Description of the aberrant Leptopilina lasallei n. sp., with an updated phylogeny of Leptopilina Förster (Hymenoptera: Figitidae: Eucoilinae)

ABSTRACT

In the search for native Asian parasitoids of Drosophila suzukii, the notorious spotted-wing Drosophila (SWD), an odd new species of Eucoilinae was discovered. Leptopilina lasallei sp. nov. is herein described and diagnosed relative to other eucoilines associated with drosophilid hosts. Morphologically, L. lasallei is somewhat aberrant within Leptopilina; phylogenetically, L. lasallei is sister group to the core Leptopilina. In the process of investigating L. lasallei, a de novo molecular phylogeny of Leptopilina was generated and is included here. The integrated approach used for the characterisation of L. lasallei, and the resulting phylogeny of Leptopilina, produced data useful to select parasitoid species for SWD biological control.http://www.zoobank.org/urn:lsid:zoobank.org:act:402D504A-4616-4524-85D7-1C13A6276F06 http://www.zoobank.org/urn:lsid:zoobank.org:act:402D504A-4616-4524-85D7-1C13A6276F06     

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.     

Systematics and fossil evidence of host-parasitoid relationships of Calamiscus Borgmeier (Diptera: Phoridae)

The life history and hitherto unknown males of Calamiscus cryptopalpis are described. A second species of this genus, C. inflativenis n. sp. is described from Costa Rica. The species C. cryptopalpis is a gregarious parasitoid of injured stingless bees in Costa Rica. The co-occurrence of a specimen of the genus Calamiscus in a piece of amber with the oldest known fossil bee is hypothesized to be the most ancient host-parasitoid relationship between a pair of insect species documented thus far. The otherwise rarely-seen fly was probably lured to the amber site by the alarm pheromones of the bee, and then trapped in the sticky tree resins.     

Global species diversity

Sixteen species from the following six orders of insects have been recorded as breeding on pteridophytes of the Lycopsida: Homoptera, Thysanoptera, Mecoptera, Diptera, Hymenoptera and Lepidoptera. All but one of these is from Selaginella, the exception being a pyralid moth from Lycopodium in Hawaii. Three new species are described from Selaginella eurynota in Costa Rica: Aleurotulus pteridophytae Martin sp. nov. (Homoptera, Aleyrodidae), Encarsia sueloderi Polaszek sp. nov. (Hymenoptera, Chalcidoidea), a parasitoid which was reared from the whitefly, and Echinothrips selaginellae Mound sp. nov. (Thysanoptera, Thripidae).

First described fossil representatives of the parasitoid wasp taxa Asaphesinae n. n. and Eunotinae (Hymenoptera: Chalcidoidea: Pteromalidae sensu lato) from Eocene Baltic amber

ABSTRACT

New Baltic amber species of Pteromalidae sensu lato are described, from two different subfamilies, Asaphesinae n. n. and Eunotinae. Asaphesinae is provided as a replacement name for Asaphinae Ashmead 1904, which is a junior homonym of the trilobite family Asaphidae Burmeister 1843. Coriotela lasallei gen. n., sp. n.. and Butiokeras costae gen. n., sp. n.. are described as the first known fossil species of Asaphesinae and Eunotinae, respectively. These species establish the minimum known age of both groups in the Eocene. Taxonomic changes are also proposed for some extant species. The genus Desantisiana Neder de Román syn. n.. is found to be a junior synonym of Notoglyptus, and its only described species is transferred as Notoglyptus jujuyensis (Neder de Román) comb. n.. The tribe Calyconotiscini, previously classified in Eunotinae, is abolished and Calyconotiscus Narendran & Saleem is transferred to Pireninae.

Three new species,a synonymy and taxonomic notes on southern African members of the dung beetle genera Scarabaeus s. str. Linnaeus, 1758 and Escarabaeus Zídek & Pokorný, 2011 (Scarabaeidae: Scarabaeinae)

Three new species are described in the dung beetle genera Scarabaeus s. str. L., 1758, and Escarabaeus Zídek & Pokorný, 2011. Two comprise, Scarabaeus karae sp. nov. and Escarabaeus remii sp. nov. and are novelties. The third comprises Scarabaeus geminogalenus sp. nov., which describes a new species previously misidentified by Péringuey in 1901 and involved in a false synonymy by Janssens (1940). Notes are provided on the type specimen of Scarabaeus galenus. A close relative, Scarabaeus vicinus is recorded for the first time. Scarabaeus natalensis is synonymized with Scarabaeus basuto. Relationships and validity of a further five species are discussed: Scarabaeus convexus with S. spretus and S. rusticus; S. ebenus with S. interstitialis. The type specimen of Scarabaeus rixosus is also discussed. Distribution maps are provided for the new species and those in the S. galenus species complex.

A second sexually dimorphic neotropical species of Macrophthalmothrips (Thysanoptera; Phlaeothripidae)

Macrophthalmothrips kiesteri sp. nov. is described from Costa Rica and Panama with remarkably enlarged fore legs in the males. This sexual dimorphism, involving male allometry and probably male competition, is apparently plesiomorphic in the genus. Reasons are given for considering the typical condition found in neotropical Macrophthalmothrips species, with both sexes having similar slender fore legs, to be apomorphic. The sister species of kiesteri is considered to be allops Hood from Belem, and these two with diasi Hood from Sao Paulo comprise a distinctive species-group.     

A new species of the genus Zhangixalus (Amphibia: Rhacophoridae) from Vietnam

ABSTRACT

A new rhacophorid species is described from Vietnam on the basis of nine specimens collected in Quan Ba District, Ha Giang Province, northeastern Vietnam. The new species is morphologically similar to Zhangixalus pinglongensis, Z. dorsoviridis, and Z. nigropunctatus, however, it differs from the latter by having the flank cream with large black blotches on axilla and groin. The genetic distance between the new species and Zhangixalus pinglongensis, Z. dorsoviridis and Z. nigropunctatus is >3.57% (16S mtDNA gene fragment). Zhangixalus jodiae sp. nov. can be distinguished from all other species of Zhangixalus and other small rhacophorid species from Southeast Asia by a combination of the following characters: size small (SVL 36.1–39.8 mm in males); head as long as wide; vomerine teeth present; dorsal surface of head and body green without spots; axilla cream with large black blotches, groin and front-rear parts of the thigh, ventral surface of tibia black with orange blotches; lower jaw region greyish, chest and belly cream.

Three new species of Laelaspis Berlese from Iran (Acari: Laelapidae), with a review of the species occurring in the Western Palaearctic Region

This paper reports on five species of mites of the genus Laelaspis associated with ants in Iran – Laelaspis astronomicus (Koch) from Tapinoma simrothi, Laelaspis equitans (Michael) from Messor sp. and Camponotus sp., Laelaspis kamalii Joharchi and Halliday sp. nov. from Tapinoma sp., Laelaspis pennatus Joharchi and Halliday sp. nov. from Tetramorium caespitum, and Laelaspis persicus Joharchi and Halliday sp. nov. from Pheidole pallidula. Laelaspis imitatus Reitblat has also been reported from Iran, in association with an unknown insect. A key to species of Laelaspis occurring in the Western Palaearctic Region is presented, with a summary of their host associations and biology.     

A new species of Sarcofahrtiopsis Hall (Diptera: Sarcophagidae) living in roosts of Spix's disk-winged bat Thyroptera tricolor Spix (Chiroptera) in Costa Rica

Sarcofahrtiopsis thyropteronthos sp. n. is described from Costa Rica. All specimens were bred from faeces taken from young, tubular leaves of musoid plants (genera Heliconia and Calathea) used as roosts by Spix's disk-winged bat Thyroptera tricolor Spix. Larvae were observed in practically all roosts suggesting a highly specialized association.

Notes on the family Macrodinychidae (Acari: Uropodina) with description of two new species

The published records of the already known Macrodinychid species are summarized and a key to the known species of the family is given. New records of the different Macrodinychus species are presented from Saint Lucia, Dominican Republic, Cuba, Costa Rica, Suriname, Fiji, New Guinea, Solomon Islands and Thailand. Two new species (Macrodinychus malayicus sp. nov. and Macrodinychus extremicus sp. nov.) are described and illustrated. The species Macrodinychus paraguayensis Hirschmann, 1975 is proved to be the junior synonym of Macrodinychus parallelepipedus (Berlese, 1916 Berlese, A. 1916. Centuria seconda di Acari nuovi. Redia., 12: 125–177.  [Google Scholar]).     

A revision of Astyanax (Characiformes: Characidae) in Central and North America,with the description of nine new species

Since the restriction of Astyanax fasciatus to Brazil, most authors have assigned Central American and southern Mexican forms of Astyanax to A. aeneus. However, molecular studies support the hypothesis that more than one taxon is involved. With the aim of clarifying the number and status of species hidden behind the name ‘A. aeneus’, this revision comprises 80 populations of Astyanax (and ‘Bramocharax’) from Panama to Texas, with comparative material from South America, based on morphological characters (mostly osteological). Astyanax aeneus is hereby restricted to the Pacific slope, from Río Papagayo, Guerrero, to Honduras. Several species are resurrected from synonymy or redescribed: A. altior (restricted to north-western Yucatán), A. argentatus (Texas and northern Mexico), A. belizianus (central-southern Belize, Izabal, Caribbean Honduras), A. brevimanus (upper Usumacinta and Grijalva, Chiapas, Quiché, Alta Verapaz), A. finitimus (Veracruz, Tabasco, northern Chiapas), A. mexicanus (restricted to Colima and the Balsas River basin), A. nicaraguensis (Caribbean Nicaragua to Sixaola, Panama), A. orstedii (south-eastern Nicaragua, Costa Rica and westernmost Panama), A. panamensis (Pacific Panama), and A. petenensis (Campeche, Petén). Nine species are newly described: A. acatlanensis sp. nov. (inland Oaxaca and Puebla), A. bacalarensis sp. nov. (Quintana Roo, northern Belize, Petén), A. cubilhuitz sp. nov. (Alta Verapaz), A. macal sp. nov. (Maya Mountains, Belize), A. ocotal sp. nov. (Lake Ocotal, highland Chiapas), A. rioverde sp. nov. (San Luis Potosí), A. salvatoris sp. nov. (Tamazulapan, Oaxaca), A. tamiahua sp. nov. (northern Veracruz) and A. tehuacanensis sp. nov. (Papaloapan, Oaxaca). Others were already recognised as different from A. aeneus, among these A. cocibolca and A. nasutus, as well as species included before in the genus Bramocharax.

Noyesaphytis (Chalcidoidea: Aphelinidae) – an unusual new genus from Madagascar,and a reassessment of Aphelininae classification based on morphology

ABSTRACT

Noyesaphytis Polaszek & Woolley gen. nov. (type species Noyesaphytis lasallei Polaszek & Woolley sp. n. ) is described from Berenty, Tuléar, Madagascar. The genus differs from its closest relatives primarily in the structure of the female antenna, which has a single, elongate flagellum preceded by four anelli, the largest of which could be interpreted as a single anelliform funicle. This type of antenna is unknown in other Aphytini, but approaches the condition found in many Signiphoridae. Noyesaphytis possesses a character state that was until now thought to be an autapomorphy of Azotidae (sole genus Ablerus), being the groove in front of the propodeal spiracle. A second putative autapomorphy shared by Azotidae and Signiphoridae, and also Noyesaphytis, is the presence of anterior projections on the metasomal sterna. However, in Azotidae and Signiphoridae these are narrow, whereas as they are broader in Noyesaphytis. The form of the wing is consistent with Aphytini, although lacking a linea calva. The presumed male of Noyesaphytis lasallei has an antennal structure completely unknown in Aphelinidae, with a 1-segmented clava preceded by an extremely elongate single funicle, and four anelli. Differences between the female and male are discussed, some of which could indicate that the male might eventually be shown to belong to a different species, although the species are undoubtedly congeneric, despite the striking difference in antennal structure which is common in Aphelinidae. The male genitalia also suggest Aphytini. Based on a phylogenetic analysis of 50 morphological characters, we provisionally place Noyesaphytis in Aphytini pending the results of a forthcoming phylogenomic analysis. The new genus is named for its collector, John Noyes (NHM, London), and the new species is named after the late John La Salle.

Taxonomy and cladistic analysis of the subgenus Xenomorellia Malloch (Diptera: Muscidae: Morellia Robineau-Desvoidy) with description of two new species

Xenomorellia Malloch, a subgenus of Morellia Robineau-Desvoidy, is revised to include two new species, Morellia (Xenomorellia) inca Nihei and Carvalho sp. nov. from South America, and M. (X.) maia Carvalho and Nihei sp. nov. from Costa Rica and Mexico. Diagnoses for M. (X.) holti (Malloch) and M. (X.) montanhesa (Albuquerque) are provided, as well as an identification key to the four species of the subgenus. A cladistic analysis was performed to test the monophyly of Xenomorellia and to recover the phylogenetic relationships among its species. Tree searches resulted in one single most-parsimonious cladogram, wherein the monophyly of Xenomorellia is supported, as well as a sister-group relationship with the Neotropical subgenus Trichomorellia Stein. Xenomorellia was divided into two clades: one with Caribbean–Andean species (maia?+?inca), and another with species from southeastern South America (holti?+?montanhesa).     

A phytophagous braconid,Allorhogas conostegia sp. nov. (Hymenoptera: Braconidae), in the fruits of Conostegia xalapensis (Bonpl.) D. Don (Melastomataceae)

Before 1989 all braconid wasps were thought to be parasitoids, but in that year the first phytophagous species was reported. Subsequently, a few other examples of phytophagy have been discovered, most of which are species of Allorhogas in the subfamily Doryctinae. Until now, all demonstrated examples of phytophagy in this genus have been as gall inducers in the fruits of Fabaceae. Here we describe a new species from Costa Rica, Allorhogas conostegia Marsh and Shaw, and provide evidence that it forms galls in the fruits of Conostegia xalapensis (Melastomataceae). We also provide information on the phenology of the plant and of the galls and the effects of the galls on the host plant, and we discuss the potential species richness of Allorhogas in the Neotropics.
