Helminth biodiversity of Costa Rican Anurans (Amphibia: Anura)

One hundred and sixty-three frogs representing 21 species collected in Costa Rica were examined for helminths. Those found were: one species of Digenea (Mesocoelium monas), one species of Cestoda (Cylindrotaenia americana), 15 species of Nematoda, 11 species represented by gravid individuals (Aplectana hylambatis, Aplectana incerta, Aplectana itzocanensis, Capillaria recondita, Cosmocerca parva, Cosmocerca podicipinus, Falcaustra costaricae, Hedruris heyeri, Oswaldocruzia costaricensis, Oswaldocruzia nicaraguensis, Rhabdias savagei) and four species represented by larvae (Physaloptera sp., Porrocaecum sp., Spirocamallanus sp., Ascarididae gen. sp.) and three species of Acanthocephala, one species represented by gravid individuals (Anuracanthorhynchus lutzi) and two species by cystacanths (Centrorhynchidae gen. sp. and Oligacanthorhynchidae gen. sp.). Mean helminth diversity (number of helminth species) per frog species was 2.4 ± 0.3 SE, range: 1–6. Forty-nine new host records are reported. Costa Rican frogs are infected by generalist helminths, which infect other species of frogs from Central and South America.     

Geographical distributions and host associations of larval parasitoids of frugivorous Drosophilidae in Japan

In Japan, dominant parasitoids attacking frugivorous Drosophilidae species were Asobara (Braconidae, Alysiinae), Leptopilina, and Ganaspis species (Figitidae, Eucoilinae). Asobara japonica was found throughout Japan, and its populations in the main islands of Japan were parthenogenetic whereas those in the subtropical islands were sexually reproducing. Other parasitoids showed rather restricted distributions; A.tabida, A. rossica, A. rufescens, and Leptopilina heterotoma occurred mainly in northern to central parts of the main islands, Ganaspis xanthopoda from central to southern parts of the main islands, A. leveri in a southern part of the main islands, and A. pleuralis, L. victoriae, and Ganaspis sp. mainly in the subtropical islands. Their major hosts were species of the D. melanogaster species group in the main islands, and species of the D. melanogaster, immigrans, and polychaeta species groups in the subtropical islands. Host use considerably varied among parasitoid species, especially in the subtropical islands.     

Gastrointestinal helminths from fifteen species of Litoria and Nyctimystes (Anura: Hylidae) from Papua New Guinea

Three hundred and ninety‐nine individuals representing 10 species of Litoria and five species of Nyctimystes (Hylidae), L. arfakiana, L. bibonius, L. eucnemis, L. genimaculata, L. impura, L. infrafrenata, L. modica, L. nasuta, L. thesaurensis, L. wollastoni, N. gularis, N. kubori, N. papua, N. pulcher and N. semipalmatus collected in Papua New Guinea were examined for helminths. Gravid individuals representing one species of Monogenea (Parapolystoma bulliense), one species of Digenea (Mesocoelium monas), 18 species of Nematoda (Aplectana krausi, Aplectana macintoshi, Aplectana zweifeli, Cosmocerca novaeguineae, Falcaustra papuensis, Icosiella papuensis, Maxvachonia adamsoni, Maxvachonia ewersi, Meteterakis crombiei, Moaciria moraveci, Ochoterenella papuensis, Oswaldocruzia bakeri, Parapharyngdon maplestoni, Parathelandros allisoni, Parathelandros andersoni, Physalopteroides milnensis, Rhabdias australiensis, Seuratascaris numidica) and one species of Acanthocephala (Acanthocephalus bufonis) were found. Also included were immature forms representing one species of Cestoda (as a metacestode), three species of Nematoda (Abbreviata sp., Rictulariidae gen. sp., Ascarididae gen. sp. in cysts), one species of Acanthocephala (unidentified cystacanth), and one species of Pentastomida [Raillietiella sp. (nymph)]. The mean helminth species richness for infected hosts was 1.3±0.6 SD (range one to three species). Sixty‐seven new host records and two new locality records are reported.     

Revision of the Trogidae of South America (Coleoptera: Scarabaeoidea)

The South American Trogidae are revised. Three genera, Trox Fabricius, Omorgus Erichson (with two subgenera, Omorgus and Haroldomorgus Scholtz), and Polynoncus Burmeister, and 47 species are recorded from the continent and its islands. Trox is represented by the ubiquitous introduced species T. scaber (L.), Omorgus is represented by 13 species and Polynoncus by 33 species. Five new species are described and all others are re-described. A key to all taxa is provided. Adults of all species and their male genitalia are illustrated and their distributions mapped. Observations are presented on phylogeny, zoogeography and biology. The new species are O. capillaceus, O. indigenus, O. nocheles, P. erugatus and P. gibberosus. Four new synonymies are proposed (synonyms listed first): O. triestinae Pittino = P. suberosus (Fabricius); P. furcifer Pittino = P. bifurcatus (Vaurie); P. parafurcatus occidentalis Pittino and P. furcillifer Pittino = P. parafurcatus Pittino. Omorgus badeni (Harold) is reinstated as a valid species. Lectotypes are designated for O. batesi (Harold) and O. badeni (Harold).     

Phylogenetic analysis of the subgenus Lampetis (Spinthoptera) (Coleoptera: Buprestidae) of North and Central America,and the West Indies

Phylogenetic relationships between species of Lampetis (Spinthoptera) of North and Central America and the West Indies were analysed by cladistic methods, based on 65 characters from the external morphology and male genitalia. Eleven species of different generic groups of the subtribe Dicercina were considered as outgroups, including also species of Lampetis (Lampetis) and one South American species of L. (Spinthoptera). The monophyly of Lampetis (Spinthoptera) is supported by two synapomorphies, but this subgenus appears to be more closely related to species of Psiloptera rather than to Old World species of Lampetis (Lampetis), suggesting that Lampetis (Spinthoptera) may be segregated from Lampetis as a different genus. The species of Lampetis (Spinthoptera) from North and Central America and the West Indies do not represent a monophyletic taxon, because L. (S.) tucumana (South American outgroup) is nested within them. Comparison of these results with a previous panbiogeographic analysis indicate that several generalized tracks possess species from different clades, thus suggesting an ancient radiation of this taxon in Mesoamerica and the Mexican Transition Zone.     

Re‐description of the lycosiformis species group of Anyphops Benoit and description of two new species (Araneae,Selenopidae)

Anyphops Benoit is a heterogeneous genus with 62 known species restricted to the Afrotropical region. It is split into four species groups using the number of ventral spine pairs on tibiae I–II. The lycosiformis species group (?=?B‐B1 species group of Lawrence) is characterized by four ventral pairs of spines and includes Anyphops lycosiformis (Lawrence), A. natalensis (Lawrence) and A. parvulus (Pocock). In this paper, I revise this species group and include here A. mumai Corronca, A. lawrencei (Roewer) and two new species: Anyphops ngome n. sp. and A. lucia n. sp. from South Africa. Drawings of the female and male genitalia and some somatic characters are given, in some cases for the first time. A key for the lycosiformis species group and a map showing the distribution of each species are provided.     

Helminths of 13 species of microhylid frogs (Anura: Microhylidae) from Papua New Guinea

In an attempt to better document the invertebrate biodiversity of the threatened fauna of Papua New Guinea (PNG), 208 microhylid frogs representing 13 species collected in 2009 and 2010 in PNG were examined for endoparasitic helminths. This study found mature individuals of one species of Digenea (Opisthioglyphe cophixali), adults of two species of Cestoda (Nematotaenia hylae, Cylindrotaenia sp.) and cysticerci of an unidentified cestode species; adults of nine species of Nematoda (Aplectana krausi, Bakeria bakeri, Cosmocerca novaeguineae, Cosmocercella phrynomantisi, Falcaustra papuensis, Icosiella papuensis, Ochtoterenella papuensis, Parathelandros allisoni, Parathelandros andersoni), and one species of Acanthocephala (cystacanths in the family Centrorhynchidae). There was a high degree of endemism among the helminth species infecting the microhylids, with 83% of the species known only from PNG. Yet the helminth fauna infecting Papuan microhylids are generalists with direct life cycles (no intermediate host) that also infect other anuran species. We thus conclude infection is more dependent upon habitat conditions than diet. Twenty-nine new host records are reported.     

Palaearctic species of Ammoplanus (Hymenoptera: Sphecidae)

The Palaearctic species of the genus Ammoplanus Giraud are revised, based on material of over 1750 specimens from Europe, North Africa and Central Asia. For almost all species it was possible to examine the type material and in six species the lectotypes have been designated, in two cases (A. perrisi and A. marathroicus) the neotypes. As a result 38 species are recognized as valid, keyed out and commented on. Eight species are described as new and four species names are here placed in synonymy. Several species are of wide distribution, which made it necessary to include also those described from Central Asia and Mongolia. The keys are made to all Palaearctic species but no material is known from the regions east of Mongolia, although four undescribed species are available from South-East Asia. The Afrotropical species are listed and most of them were also examined. Two subgenera are recognized in the region; 32 species are classified in Ammoplanus sensu stricto and six in the subgenus Ammoplanellus. In the nominal subgenus the following species are described as new: A. atlasensis from Morocco, A. biscopula from Israel, A. biskrensis from Algeria, A. denesi from Turkey (Anatolia), A. freidbergi and A. kaplanae from Israel, A. minutus from Bulgaria and Turkey and A. strumae from Bulgaria and Greece. New synonymy: A. angelae becomes a junior synonym of rhodesianus (known before only from Africa), A. crudelis a synonym of A. kaszabi, A. handlirschi a synonym of A. marathroicus, A. suarezi a synonym of A. kohlii, A. subcompressus of A. gegen, A. orbiculatus of A. simplex and A. zarcoi of A. kohlii; A. wesmaeli is confirmed as a synonym of A. perrisi. Otherwise the synonymy is corrected under A. bischoffi and the names A. dusmeti and A. curvidens are re-established as valid. In a short review of the African species A. (Ammoplanellus) cradockensis Arnold, 1959 is placed as a new synonym under A. (Ammoplanellus) latiscapus Leclercq, 1959. The nomenclatural changes are explained under the relevant species.     

Gastrointestinal helminth communities of two gekkonid lizard species,Nactus multicarinatus and Nactus pelagicus (Squamata: Gekkonidae), from the Republic of Vanuatu,Oceania

Gastrointestinal helminth communities of two gekkonid species, Nactus multicarinatus and Nactus pelagicus, from the Vanuatu Archipelago were examined. Both helminth communities were depauperate: N. multicarinatus harboured one species of Digenea, Mesocoelium monas, one species of Cestoda, Oochoristica javaensis, four species of Nematoda, Hedruris hanleyae, Parapharyngodon maplestoni, Physocephalus sp. (larvae in cysts), Filarioidea gen. sp. (juvenile); N. pelagicus harboured one species of Cestoda, O. javaensis, four species of Nematoda, H. hanleyae, Falcaustra tannaensis, P. maplestoni, Physocephalus sp. (larvae in cysts). In each helminth community P. maplestoni represented a core species and H. hanleyae was a secondary species. It is postulated that the helminth fauna infecting lizards of the Vanuatu Archipelago originated in Australia and Papua New Guinea and reached the archipelago by rafting; their establishment in Vanuatu was fortuitous.     

Filth inhabiting flies of Dacca city

Summary

Information obtained about the association of various flies with different types of filth in Dacca city, their life histories, food preference of the larvae, and the seasonal changes of their population has been recorded.

The filth of Dacca city has been classified into the following eight categories for the present work. (1) Human excrement, (2) cow dung, (3) manure heaps, (4) garbage and kitchen refuse, (5) decaying fruits and vegetables, (6) carrion, (7) rotten fish and meat, and (8) municipal sewage and other liquid waste.

In total nine fixed areas in different parts of the city were visited regularly to collect adult flies, or their eggs or larvae.

The association of various flies with the above eight types of filth has been discussed.

The duration of the life cycle from oviposition to emergence of the adults was recorded for five species of Psychoda, seven species of Musca, one species of Calliphora, two species of Chrysomyia, two species of Lucilia, and three species of Sarcophaga, during summer and winter.

Food preferences of the larvae of two common species of Musca, two species of Sarcophaga, one species of Lucilia, one species of Calliphora, and two species of Chrysomyia have been recorded.

The trend of the seasonal variation of the various fly populations have been discussed.     

Metazoan endoparasites of 18 anuran species from the mesophytic semideciduous Atlantic Forest in southern Brazil

Brazil has the richest anuran biodiversity in the world and many species have not yet been studied for parasites. One hundred and forty frogs belonging to 18 species (Rhinella schneideri, Dendropsophus aff. minutus, Dendropsophus nanus, Hypsiboas albopunctatus, Hypsiboas punctatus, Hypsiboas raniceps, Phyllomedusa tetraploidea, Pseudis platensis, Scinax fuscovarius, Trachycephalus typhonius, Leptodactylus chaquensis, Leptodactylus fuscus, Leptodactylus aff. latrans, Leptodactylus mystacinus, Leptodactylus podicipinus, Physalaemus cuvieri, Physalaemus nattereri and Elachistocleis bicolor) collected in aquatic habitats in forest remnants and surrounding agricultural landscapes in southern Brazil were examined for endoparasites. Twenty-four species of endoparasites were identified among 21 adult and three larval individuals: one species of Monogenea, Polystoma lopezromani; eight species of Digenea, Catadiscus marinholutzi, Catadiscus propinquus, Choledocystus simulans, Gordoderina sp., Neohaematoloechus neivai, Rauschiella lenti, Rauschiella linguatula, Rauschiella repandum; one species of Cestoda, Ophiotaenia sp.; one species of Acanthocephala, Centrorhyncus sp.; 12 species of Nematoda, Aplectana sp., Aplectana travassosi, Cosmocerca podicipinus, Raillietnema sp., Schrankiana formolusa, Falcaustra mascula, Oxyascaris oxyascaris, Ochoterenella digiticauda, Physaloptera sp., Brevimulticecum sp., Rhabdias sp., Parapharyngodon hylidae; and one species of Annelida, Dero (Allodero) lutzi. The endoparasite fauna found is constituted by generalist species. Two new records of occurrence in Brazil and 33 new host records are reported.     

The Thysanoptera Haplothripini (Insecta: Phlaeothripidae) of Iran

In Iran, 4 genera and 27 species are recorded of the Thysanoptera tribe Haplothripini (Phlaeothripidae, Phlaeothripinae): Dolicholepta Priesner with 1 species, Haplothrips Amyot and Serville with 23 species, Neoheegeria Schmutz with 2 species, and Plicothrips Bhatti with 1 species. Identification keys are provided to these taxa. Three new synonyms are established: H. inoptatus Priesner is a junior synonym of H. globiceps Bagnall, H. iraniensis Priesner is a junior synonym of H. maroccanus Priesner, and H. scythicus Knechtel is a junior synonym of H. leucanthemi (Schrank). Reports of H. cerealis Priesner from Iran are considered to be misidentifications of H. tritici Kurdjumov, and comments are made on the identity of several predatory species related to H. subtilissimus (Haliday) and H. globiceps Bagnall. Several character states used for recognizing taxa in Haplothrips are discussed, and available biological data for each species are presented.     

Seven new species of Amynthas (Clitellata: Megascolecidae) and new earthworm records from Taiwan

Earthworm specimens collected in southern Taiwan consisted of seven new species of Amynthas and several previously known species, mostly widely distributed peregrines. The new species are A. nanrenensis of the octothecal A. corticis species group, A. monsoonus and A. huangi of the sexthecal A. aelianus species group, and four proandric octothecal species: A. chaishanensis, A. hengchunensis, A. kaopingensis and A. ailiaoensis. Amynthas chaishanensis has dorsal intrasegmental spermathecal pores, but the other three proandric species have dorsal, lateral or ventral intersegmental spermathecal pores, respectively. The proandric species are united by several features, including the enclosure of segment xi in a sac, as in A. formosae (also proandric), octothecal with spermathecae in vi–ix, spermathecal diverticula stalks generally kinked and often enclosed in membrane, and prostatic ducts divided polytomously into numerous small ductlets, which may be grouped into bundles of two to five. In A. ailiaoensis the prostatic duct trunk contains up to seven separate lumens in the ental half, surrounded by the circular muscle of the duct, while in A. chaishanensis the prostatic duct trunk contains about 40 small lumens. Of the previously known species in the collection, Pontodrilus litoralis and Metaphire houlleti are first reported from Taiwan. Additional locations for A. incongruus and A. robustus are given, and in the latter case the material appears to be the usual male‐sterile morph. Other species found are Pontoscolex corethrurus, Amynthas corticis, A. gracilis, Metaphire californica, and Polypheretima elongata.     

Encarsia (Hymenoptera: Aphelinidae) parasitoids of Bemisia species in Taiwan (Hemiptera: Aleyrodidae)

The whitefly genus Bemisia (Hemiptera: Aleyrodidae) is represented by five species in Taiwan, including the notorious global pest Bemisia tabaci. A catalogue of Encarsia species attacking these whiteflies, based almost entirely on previously unpublished records, is provided. A key for the identification of the 17 Encarsia species known to parasitize Bemisia species in Taiwan is provided. Three new species, E. guangxingana Shih, Ko and Polaszek sp. nov., E. lineolata Shih, Ko and Polaszek sp. nov. and E. magnalata Shih, Ko and Polaszek sp. nov., are described from Taiwan. These new species were all reared from Bemisia giffardi.     

Copepods of the genus Colobomatus (Poecilostomatoida: Philichthyidae) from fishes of the family Sillaginidae (Teleostei: Perciformes)

Six species of Colobomatus, five of which are new to science, were found in a survey of 26 species of sillaginid fishes in the Indo-west Pacific. Three of the species are closely related and occur in the head cavities of various species of their hosts. Colobomatus sillaginis West, 1983 is recorded in Sillaginodes punctata and 12 species of Sillago, from around the coast of Australia and in the Gulf of Thailand, representing many new host and locality records. Female C. asiaticus sp. nov. are described from southeast Asia and the Persian Gulf, in three species of Sillago. Female C. arabicus sp. nov. are described from two species of Sillago occurring only in the Persian Gulf. A second intrageneric grouping of three species of Colobomatus inhabits a different microhabitat: tubes of the lateral line scales. Each of these species infects several sillaginid fishes, and in contrast to members of the first species-group they are entirely allopatric with each other. In Australia, female C. fulloonae sp. nov. are described from three species of Sillago in northern waters, and female C. charleah sp. nov. are described from two species of Sillago and Sillaginodes punctata in southern waters. Female C. westi sp. nov. are described from three species of Sillago in the waters of eastern Asia (Japan, Korea and China). Only one male specimen of each of C. arabicus sp. nov., C. charleah sp. nov. and C. westi sp. nov. was found.     

New species of Orasema (Hymenoptera: Eucharitidae) from Central and South America

ABSTRACT

Six new species of Orasema are described. Four species are placed into a newly recognised lasallei species group: Orasema lasallei sp. nov. (Costa Rica, Honduras, Mexico, Nicaragua), O. janzeni sp. nov. (Costa Rica), O. peckorum sp. nov. (Brazil) and O. vasquezi sp. nov. (Colombia). One species is placed in the wayqecha group, Orasema masneri sp. nov. (Ecuador). One other species is currently unplaced to species group, O. longinoi sp. nov. (Costa Rica). Orasema lasallei was taken from a nest of Pheidole vorax (Fabr.) and an undescribed species near O. longinoi from a nest of Pheidole dossena Wilson (Myrmicinae). The morphology of the digitate labrum is discussed with respect to other Eucharitidae.     

Two new species of phytoseiid mites (Acari: Phytoseiidae) from the State of São Paulo,Brazil

Two new species of phytoseiid mites, Amblyseius ica and Typhloseiopsis dorsoreticulatus, from the State of São Paulo, Brazil, are described and illustrated. Amblyseius ica belongs to the americanus species group and dombeyus species subgroup, being the second species of that subgroup. Typhloseiopsis dorsoreticulatus is the first species of the genus Typhloseiopsis recorded outside Central America.     

Taxonomy of the Cecropia-inhabiting Azteca ants

Cecropia trees and several species of the ant genus Azteca form the most conspicuous ant-plant association in the Neotropics. The taxonomy and biology of the Cecropia-associated Azteca are reviewed. A key to queens is provided for the 13 species known to be obligate inhabitants of Cecropia trees, and a key to workers for the five species known from Costa Rica. Taxonomic changes include four new species and extensive synonymy. Individual species accounts contain taxonomic, behavioural, and ecological information. Evolutionary relationships among the species, and the community ecology of the Cecropia-Azteca association, are discussed.     

Annelids (Polychaeta and Oligochaeta) from the Sea of Marmara,with descriptions of five new species

This paper deals with annelids (Oligochaeta and Polychaeta) collected in the Sea of Marmara between 2006 and 2010 at depths from 0 to 66 m. A total of five oligochaete and 198 polychaete species were found. Five polychaete species, namely Prosphaerosyllis marmarae sp. nov., Levinsenia demiri sp. nov., Levinsenia kosswigi sp. nov., Levinsenia marmarensis sp. nov. and Levinsenia tribranchiata sp. nov. are new to science, and five oligochaete and 84 polychaete species are new to the fauna of the Sea of Marmara. A list of species found in the region and their maximum densities are presented at depth intervals. The present material includes six alien polychaete species, Paraprionospio coora, Polydora cornuta, Prionospio (Minuspio) pulchra, Pseudopolydora paucibranchiata, Chaetozone corona and Metasychis gotoi, of which the latter four species were new records for the region.
