Two new species of Hatschekia Poche, 1902 (Copepoda,Hatschekidae) parasitic on two inshore fishes from Antofagasta,Chile

Hatschekia affluens sp. nov., parasitic on the gills of Pimelometopon maculatus, and Hatschekia amphiprocessa sp. nov., on those of Paralabrax humeralis, both from Antofagasta, Chile, are described and illustrated. These two species constitute the second record of Hatschekia from the coast of Chile.     

Species of Gyrodactylus von Nordmann, 1832 (Monogenea Gyrodactylidae) from poeciliid fishes,with a description of G. turnbulli sp. nov. from the guppy,Poecilia reticulata Peters

Gyrodactylus bullatarudis Turnbull, 1956 is described from Xiphophorus helleri × X. maculatus hybrids. Specimens from this host were morphologically indistinguishable from material of this species from Poecilia reticulata and P. sphenops, although differences in host specificity were noted. Gyrodactylus turnbulli sp. nov., a member of the G. eucaliae species group, is described from Poecilia reticulata. Gyrodactylus turnbulli has frequently been confused with G. bullatarudis, although the two species are only distantly related. They can be distinguished by differences in the structure of the dorsal bar, which is deeply notched in G. bullatarudis, and by the relative length of the ventral bar processes.     

Apelaunothripini from the Philippines (Thysanoptera: Phlaeothripidae)

Summary

The relationships of the phlaeothripine tribe Apelaunothripini is discussed. Four genera and thirteen species are recorded from the Philippines, including the following two new genera and nine new species: Apelaunothrips cephalicus sp. nov., A. fasciatus sp. nov., A. flavicornis sp. nov., A. marginalis sp. nov., A. philippinensis sp. nov., A. rostratus sp. nov., A. simpliceps sp. nov., Lizalothrips luzonensis gen. and sp. nov., Paradexiothrips bispinosus gen. and sp. nov. Keys are provided to the four genera included in the Apelaunothripini, and to the ten Apelaunothrips species from the Philippines.     

Parashiinoa mackayi gen. nov., sp. nov. (Poecilostomatoida: Shiinoidae), a new parasitic copepod from two Australian species of Pomadasys (Haemulidae)

A new genus, Parashiinoa, is proposed for a new species of parasitic copeepod found attached at the base of the dorsal fins of two species of Australian haemulid fishes, Pomadasys maculatus (Bloch) and P. argenteus (Forsskål). The new species, P. mackayi, is described and illustrated. One species of the genus Shiinoa, S. bakeri Cressey and Cressey, is transferred to the new genus. A redefinition of the family Shiinoidae is provided.     

The genus Platypalpus Macquart (Diptera: Hybotidae) from Northeast Thailand with comments on the species groups in the Oriental region

The first records on the genus Platypalpus Macquart from Thailand are presented including 10 species new to science: P. fai sp. nov., P. gaemluang sp. nov., P. hualuang sp. nov., P. isaanensis sp. nov., P. nuadkhao sp. nov., P. phomyaaw sp. nov., P. seedam sp. nov., P. seeluang sp. nov., P. siamensis sp. nov., and P. thaicus sp. nov.. A key to these species is provided. All species of Platypalpus known from the Oriental Region (totally 54) are arranged into the species groups currently established for the genus. Eight species groups are recognized from the Oriental Realm and the distribution of each group is briefly discussed. The P. albiseta‐group is most diverse in the Orient with 16 species recorded. Two species of this group possess a modified structure and vestiture of certain abdominal segments that is the first record of this phenomenon in Platypalpus. Also, within the P. albiseta‐group a complex of closely related species sharing an apomorphous condition of the hypoproct has been recognized. In these species the structure of the hypoproct is likely to deal with clasping during copulation instead of the cerci and epandrial lamellae.

Two new Encarsia species (Hymenoptera: Aphelinidae) reared from eggs of Cicadellidae (Hemiptera: Auchenorrhyncha) in Argentina: an unusual new host association

Males of two undescribed Encarsia species were reared from eggs of two cicadellid species during a study of egg parasitoids of corn leafhopper, Dalbulus maidis (DeLong and Wolcott) in northwestern Argentina. Samples were collected during the summer of 2004–2007 using sentinel eggs, and several males of a new species of Encarsia (Hymenoptera: Chalcidoidea: Aphelinidae) were obtained. A single male of a closely related Encarsia species, also previously undescribed, was reared from an egg of another cicadellid on maize, Plesiommata mollicella (Fowler). These are the first records of any Encarsia species reared from eggs of Cicadellidae. The two new species are described as Encarsia dalbulae Polaszek and Luft Albarracin sp. nov., and Encarsia mollicellae Polaszek and Luft Albarracin sp. nov.     

The Cassidininae Hansen, 1905 (Crustacea: Isopoda: Sphaeromatidae) of Australia

The Cassidininae of Australia are revised. The status of the subfamily is assessed and it is concluded that, as presently constituted, the Cassidininae is an artificial taxon. It is maintained here as a taxon of convenience (sensu lato) until the other sphaeromatid subfamilies can be reassessed, but a new diagnosis (sensu stricto) is given. The genus Cassidina is redescribed. Three new genera are established: Agostodina gen. nov. (type species: A. munta sp. nov.), Apemosphaera gen. nov. (type species: A. naranagi sp. nov.) and Discidina gen. nov. (type species: D. banawarra sp. nov.). New diagnoses are provided for the genera Cassidina Milne Edwards, Chitonopsis Whitelegge, Cassidinidea Hansen, Paracassidina Baker, Syncassidina Baker and Platysphaera Holdich and Harrison. The genus Dies is placed in synonymy with Cassidinidea and an annotated list is given of all species of the genus. The following new species (excluding the new type species) are described: Chitonopsis booyoolie, Agostodina munta, Paracassidina anasilla, P. bakeri, P. bamarook, P. bilbie, P. cervina, P. dama, P. fuscina, P. incompta, P. kutyo, P. munna, P. petala, P. prolata, P. wurrook and Cassidinidea korpie. Keys to the Australian genera and species are given.

The species formerly classified in the genus Afidentula Kapur from New Guinea and Aru Islands are revised. As a result of detailed analysis of mouth parts and genital structures of the species, two new genera are proposed: monotypic Lalokia gen. nov. from Aru Islands and New Guinea, with Lalokia aruensis (Crotch) (comb. nov.), and Papuaepilachna gen. nov. from New Guinea including Papuaepilachna bivacana (Bielawski) (comb. nov.), P. kapuri (Bielawski) (comb. nov.), P. nasti (Bielawski) (comb. nov.), P. tenmana (Bielawski) (comb. nov.), P. watalai (Jadwiszczak) (comb. nov.) and P. wiebesi (Bielawski) (comb. nov.). All species are illustrated and an identification key to the species of Papuaepilachna is provided. A key to the genera of Epilachnini from New Guinea and Aru Islands is also provided. http://www.zoobank.org/urn:lsid:zoobank.org:pub:F721B07F-CBF0-4516-853D-1FD434FE06F1     

Two new species of Phylactella (Bryozoa Cheilostomatida) from the Mediterranean area belonging to the P. labrosa (Busk) complex of species

Examination of fossil and Recent specimens from the Sicilian area belonging to the Phylactella labrosa ‘complex’ revealed two new species: P. mediterranea sp. nov., a Pleistocene-to-Recent taxon and P. megarensis sp. nov., from Pleistocene sediments from eastern Sicily. Ecological, geographical and stratigraphical distribution of both new species are discussed also in comparison with P. labrosa.     

On the occurrence of blood flukes (Sanguinicolidae: Trematoda) in British freshwater fish

Summary

A new genus, Cahara, is described, based upon Dalpada brevivitta Walker, as its type species C. brevivitta (Walker) comb. nov., C. confusa (Distant) comb. nov. and C. jugatoria (Lethierry) comb. nov. are redescribed and illustrated. C. murreeana sp. nov., C. montana sp. nov., C. kightleyi sp. nov., C. chaubattia sp. nov., C. bhowaliana sp. nov. and C. metallica sp. nov. are described as new. The genus Cahara occurs in the subhimalayan region of India, Pakistan and Nepal. Its members feed on deciduous trees, apple, walnut, fir, deodar, Bauhinia, etc. Superficially, the species resemble one another, as well as members of Dalpada s. lat. in their coloration and some have been confused with species like Dalpada versicolor in the past, but certain characters, like the shape of the head, the simple second antennal segment and more particularly the male and female genitalia, distinguish the genus Cahara from all others. A key to the species of Cahara is provided.     

New species of Australian arid zone chelonine wasps from the genera Phanerotoma and Ascogaster (Hymenoptera: Braconidae) informed by the ‘Bush Blitz’ surveys of national reserves

Here we focus on the poorly studied braconid wasp subfamily Cheloninae for the arid zone of the Australian continent, using material, in part, resulting from comprehensive surveys of three arid zone reserves. The Bush Blitz programme is a multi-institutional project with the aim of documenting the diversity of the flora and fauna in Australia’s National Reserve System, with describing new species being a key focus of the programme. In total, 11 species from the genera Ascogaster and Phanerotoma are treated, with species’ delimitation based on both molecular and morphological data. Two species are redescribed (Phanerotoma behriae Zettel, 1988a and P. decticauda Zettel, 1988a) and nine species are described as new (Ascogaster brevivena sp. nov., A. ferruginegaster sp. nov., A. prolixogaster sp. nov., A. rubriscapa sp. nov., Phanerotoma bonbonensis sp. nov., P. bushblitz sp. nov., P. lutea sp. nov., P. nigriscapulata sp. nov. and P. witchelinaensis sp. nov.). Keys to the arid zone species of these two genera are provided, along with a species richness estimation of Australian chelonine wasps.

Most species are heterotrophs drawn from the euglendis, dinoflagellates, kinetoplastids, bicosoecids, heteroloboseids, and a variety of taxa of uncertain affinities. The work emphasizes the rich variety of protist taxa in marine benthic sites. New names are Amphidinium corrugatum, Anisonema glaciale, Bodo cephalophorus, B. platyrhynchus, B. saliens, Bordnamonas tropicana, Cafeteria ligulifera, C. marsupialis, C. minuta (Ruinen, 1938) nov. comb., Cryptaulax elegans, Dinematomonas inaequalis = Dinema inaequale, Dinematomonas maculata (= Dinema maculatum), Dinematononas valida (= Dinema validum), Diplonema ambulator, Diplonema metabolicum, Discocelis punctata, Dolium sedentarium, Goniomonas amphinema, Goniomonas pacifica, Gyrodinium oblongum, Heteronema exaratum, H. splendens, H. vittatum, Mastigamoeba psammobis, M. skujae nom. nov., Massisteria marina, Metopion fluens, Metromonas grandis, M. simplex (Griessmann, 1913) nov. comb., Notosolenus alatellus, N. navicula, N. ostium, N. scutulum, N. urceolatus, N. tamanduensis, N. triangularis, Percolomonas cuspidata, P. descissa (Perty, 1852) nov. comb., P. elephas (Klug, 1936) nov. comb., P. membranifera, P. pyriformis (Klebs, 1892) nov. comb., P. salina (Entz, 1904) nov. comb., P. spinosa (Klug, 1936) nov. comb., P. sulcata (Stein, 1878) nov. comb., Petalomonas boadicea, P. marginalis, P. minor, P. poosilla, P. raiula, Phyllomitus granulatus, P. vesiculosus, Platychilomonas psammobia, Ploeotia adhaerens, P. corrugata, P. decipiens, P. heracleum, P. discoides, P. longifilum, P. oblonga, P. pseudanisonema, P. punctata, P. robusta, P. scrobiculata, P. tenuis, Protaspis obliqua, P. verrucosa, P. gemmifera, P. tegere, Pseudoperanema (= Peranema) dolochonema, Thecamonas filosa, T. mutabilis (Griessmann, 1913) nov. comb., T.trahens, Urceolus cornutus, U. cristatus.     

Chelodesmid studies. XVIII. On some new or poorly-known taxa in the tribe Batodesmini (Polydesmida: Chelodesmidae)

Summary

Some new and poorly-known taxa of batodesmine diplopods are described from northern South America, with notes on their affinities. New genera include Igaraparana, based on I. batesi, sp. nov. from Amazonian Colombia; Curimagua, based on C. granulata, sp. nov. from Edo. Falcon, Venezuela; and Cheirogonus, based on C. pittieri, sp. nov. from Panama. The inadequately proposed species Leptodesmus interrupticolor Silvestri (southeastern Ecuador) is redescribed and figured from type material, and referred to Cordilleronomus as its third species. The enigmatic genus Tunochilus Chamberlin, 1950, is clarified and referred to the Batodesmini from its incorrect location in the Cryptodesmidae, with notes and drawings made from a paratype of the type species T. marginis; the presumptive congener T. marcuzzii is described as new from material taken at Caracas, Venezuela.     

A new genus and three new species of Phoridae (Diptera) parasitizing ants (Hymenoptera) in Sulawesi

Iridophora clarki gen. nov., sp. nov., Megaselia sembeli sp. nov. and M. kodongi sp. nov. are described. The females of I. clarki attack the workers of the ant Iridomyrmex cordatus (Smith). The same ant species is also attacked by M. sembeli, and the morphology of this species indicates that it is close to P. beirne Brues, the typespecies of the genus Plastophora. The loss of the type-material of the latter species prevented synonomy of the genus when it was re-evaluated (Disney, 1978). The detailed examination of M. sembeli now indicates that the genus Plastophora is a synonym of Megaselia (syn. nov.). A consequence is that P. dubitata Brues, 1935 becomes a homonym of M. dubitata (Malloch, 1912) and the replacement name M. bruesi nom. nov. is proposed. The females of M. kodongi attack workers of a species of Pheidologeton which forages on the forest floor. The habit of Iridomyrmex cordatus in using covered ways up trees appears to be related to its extreme vulnerability to attack by these two phorides.     

Three new species of earthworms belonging to the genera Amynthas and Metaphire (Oligochaeta: Megascolecidae) from Yunnan,China

ABSTRACT

Herein, three new species are described, all from Yunnan Province, China: Amynthas hiatus sp. nov., Amynthas recavus sp. nov. and Metaphire daliensis sp. nov. Amynthas hiatus sp. nov. belongs to the Amynthas aeruginosus-group, A. recavus sp. nov. belongs to the Amynthas corticis-group and M. daliensis sp. nov. belongs to Metaphire insulana-group. Amynthas hiatus sp. nov. and M. daliensis sp. nov. have two pairs of spermathecal pores in 7/8-8/9, A. recavus sp. nov. has four pairs of spermathecal pores in 5/6-8/9. The male pores of A. hiatus sp. nov. are 1/3 circumference apart ventrally and each on top of a large, raised pulvinate pad; the male pores of A. recavus sp. nov. are 2/5 circumference apart ventrally and each on top of a raised, elliptic, collapse-topped porophore; the male pores of M. daliensis sp. nov. are 2/5 circumference apart ventrally and in the oval copulatory chambers. In this paper, the anatomical and morphological characters of these three species are described. We also sequenced COI and 12S gene fragments in order to provide an analysis of K2P distances and a neighbour-joining tree.
