Description of the Adult Male of Stylops advarians Pierce (Strepsiptera: Stylopidae)

The morphology of the adult male of Stylops advarians Pierce is described for the first time. This species was previously known only from the endoparasitic adult female and the host-seeking, first-instar larva. Members of Stylops are cosmopolitan, and Stylops advarians can be found parasitizing Andrena milwaukeensis Graenicher in western Canada.

AbstractThe first instar larva of a species of the Australian endemic genus Aenigmetopia Malloch is described for the first time, along with the first instar larvae of three other Australian species representing the genera Amobia Robineau-Desvoidy and Protomiltogramma Townsend. Larval morphology was analysed using a combination of light microscopy, confocal laser scanning microscopy and scanning electron microscopy. The following morphological structures are documented: pseudocephalon, antennal complex, maxillary palpus, facial mask, modifications of thoracic and abdominal segments, anal region, spiracular field, posterior spiracles and details of the cephaloskeleton. Substantial morphological differences are observed between the three genera, most notably in the labrum and mouthhooks of the cephaloskeleton, sensory organs of the pseudocephalon, spinulation, sculpture of the integument and form of the spiracular field. The first instar larval morphology of Aenigmetopia amissa Johnston, Wallman, Szpila & Pape corroborates the close phylogenetic affinity of Aenigmetopia Malloch with Metopia Meigen, inferred from recent molecular analysis. The larval morphology of Amobia auriceps (Baranov), Protomiltogramma cincta Townsend and Protomiltogramma plebeia Malloch is mostly congruent with the morphology of Palaearctic representatives of both genera.

Preimaginal stages of the six species of Hydraenidae presently known from Cuba were obtained by rearing adults in the laboratory. Eggs of Hydraena perkinsi Spangler, 1980, H. decui Spangler, 1980 and H. franklyni Deler-Hernández & Delgado, 2012 are described and illustrated for the first time. The first instar larva of Gymnochthebius fossatus (LeConte, 1855) is redescribed, adding some new remarkable morphological characters including what could be the first abdominal egg-burster reported for this family. All larval instars of H. perkinsi, H. guadelupensis Orchymont, 1923 and Ochthebius attritus LeConte, 1878 are described and illustrated for the first time, with a special emphasis on their chaetotaxy. The second instar larva of G. fossatus along with first and third instar larvae of H. decui and H. franklyni are also studied for the first time. The pupal morphology and vestiture of a species belonging to the genus Hydraena are described for the first time, based on the pupa of H. perkinsi. Biological notes for several preimaginal stages of the studied species are also given.

First Time

The comparactive morphology of the male and female postabdomen of the Australian Tachinidae was studied in a survey which included 152 species of representative genera from all subfamilies except Dufouriinae. The value of the structure of the postabdomen for the higher classification of the family was ascertained, and new information gained which has allowed a better understanding of the correct taxonomic position of some problem groups of tachinids. It was possible to recognise suites of characters for each sex to define each subfamily, but this was not possible at tribal or generic levels in most groups. The male terininalia are diagnostic at specific level. The survey also allowed the discovery of, or confirmed, the reproductive habit of the included genera and provided information on the first-instar larva of 52 species, many of which larvae are described below for the first time. Characters of puparia which may have taxonomic value are discussed and illustrated.

The monotypic genus Pentaneurella Fittkau & Murray was originally described based on larvae, pupal exuviae and pharate males. The latter prevented the observation of key features, such as wing dimensions, abdominal coloration pattern, and hypopygial apodemes (sternapodeme and phallapodeme), and the description of the adult male was considered incomplete by the authors. Herein, the adult female of Pentaneurellakatterjokki is described for the first time, and the adult male, pupa and larva are redescribed and figured based on specimens recently collected in Germany and Norway. We also discuss the phylogenetic position of Pentaneurella.

Selection Of

The biology and morphology of early larval instars of Entedon costalis Dalman (Hymenoptera: Eulophidae), are described in detail for the first time. The parasitoid-host association of E. costalis was revealed as a result of selection of candidate host based on combination of assumptions based on biology of related species and field surveys. E. costalis proved to be an egg-larval parasitoid of the weevil Glocianus punctiger (Gyllenhal), which is associated with dandelion (Taraxacum officinale G.H. Weber ex Wiggers). Parasitism rate of G. punctiger by E. costalis was 25% in the model patch which was sampled in May, where infestation of dandelion inflorescence by G. punctiger was 27%. The female of E. costalis lays her egg into the host egg, but the first instar larva hatches within the first instar host. Larvae of G. punctiger start their feeding as internal flower-stalk borers, continue as seed-eaters in flowerheads, and then pupate underground when matured coincident with seed dispersal (generally in the end of May). Parasitized and unparasitized mature larvae of G. punctiger pupate underground, in earthen cells, where the parasitoid larvae finally consume their hosts and pupate 2–3 days thereafter. Adults of E. costalis emerge the following spring (about mid April), as dandelions being flowering. The morphology of immature stages and behaviour of adults is described. Various peculiarities of parasitoidhost relationships superparasitism, siblicide, host immune response are described and discussed. DNA sequences of the nuclear 28S D2 rDNA gene were obtained for E. costalis.

The adult male of Fiorinia externa Ferris is described for the first time. Its morphology agrees with that of previously described adult males in the tribe Diaspidini, and suggests a close affinity to Pseudaulacaspis. F. externa has two complete overlapping generations per year on the needles of eastern hemlock, Tsuga canadensis (L.) Carrieré, in the eastern Tennessee (USA) southern Appalachians. Adult females (both gravid and non-gravid) and first-instar nymphs were the dominant overwintering stages, although all stages apart from the adult males were present throughout the winter months. Adult males began emerging in mid March with emergence peaks in mid April to early May and again in mid to late September.

Abstract The monotypic genus Sturmiodexia Townsend, 1919 is a poorly known Neotropical taxon. Herein a new generic synonymy is proposed for this genus: Platyrrhinodexia Townsend, 1927 syn. nov. Two new combinations are assigned for Sturmiodexia: S. moyobambensis (Townsend, 1929) comb nov. and S. punctulata (Townsend, 1927) comb nov. Redescriptions were done for S. punctulata, S. rubescens Townsend 1919 and S. muscaria (Walker 1853). With these new propositions, Sturmiodexia is left with four species. In addition, the male and female terminalia, and the first instar larva, are described and illustrated for the first time for S. punctulata. Finally, a diagnose for Sturmiodexia and a key to all species is given.

The first instar larva of Diaphorocera chrysoprasis Fairmaire, 1863, a Western Saharan species, is described and figured for the first time. Adults of D. chrysoprasis were collected in Tunisia and larvae were reared ex ovo under laboratory conditions. Both egg and triungulin are described and illustrated by SEM and light microscope. The triungulin shows a campodeiform morphology, typical of non phoretic Meloinae. From the comparison between the first instar larvae of Cerocoma, the single other genus of the tribe Cerocomini whose larvae were known, and Diaphorocera, some distinctive characters are recognised. The phylogenetic placement of the tribe Cerocomini within the family is discussed.

The Australian species of Carcelia Robineau-Desvoidy are revised and the genus redescribed. C. noctuae (Curran) is confirmed as a synonym of C. illota (Curran). The subgenera Carceliella Baranov, Catacarcelia Townsend and Euryclea Robineau-Desvoidy also C.s.s. malayana Baranov are recorded from Australia for the first time. Twelve new species are described but 15 other species are left unnamed until further material is available. The new species are: actaeosa; burnsi; candens; capyrosa; flavitibia; hackeri; kindaitchin; paluma; pesitra;prominens; talwurrapin; and vicinalis. Keys to the genera of Australian Carceliini and to subgenera (five) and species (32) of Carcelia are provided; the key to species of Catacarcelia includes both Australian and Oriental species. The first-instar larva of C. hardyi (Curran) is briefly described. Knowledge of the remaining genera of Australian Carceliini is insufficient for their detailed treatment but pertinent comments on each are given. Thecocarcelia Townsend and Argyrothelaira froggattii Townsend are recorded for the first time from Australia. A diagnosis of the tribe is also given.
