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.

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.

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.

A data matrix of 23 generic or subgeneric taxa versus 24 characters and a shorter matrix of 15 characters were analyzed by means of ordination, cluster analyses, parsimony, and compatibility methods (the last two of which are phylogenetic tree reconstruction methods) and the results were compared inter alia and with traditional methods. Various measures of fit for evaluating the parsimony methods were employed. There were few compatible characters in the data set, and much homoplasy, but most analyses separated a group based on Stylaria from the rest of the family, which could then be separated into four groups, recognized here for the first time as tribes (Naidini, Derini, Pristinini, and Chaetogastrini). There was less consistency of results within these groups. Modern methods produced results that do not conflict with traditional groupings. The Jaccard coefficient minimizes the significance of symplesiomorphy and complete linkage avoids chaining effects and corresponds to actual similarities, unlike single or average linkage methods, respectively. Ordination complements cluster analysis. The Wagner parsimony method was superior to the less flexible Camin–Sokal approach and produced better measure of fit statistics. All of the aforementioned methods contain areas susceptible to subjective decisions but, nevertheless, they lead to a complete disclosure of both the methods used and the assumptions made, and facilitate objective hypothesis testing rather than the presentation of conflicting phylogenies based on the different, undisclosed premises of manual approaches.

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.

This paper offers the initial description ofthe first instar larva of Protocalliphora falcozi Séguy, 1928 (Diptera: Calliphoridae) and redescription of the second and third instar larvae and puparium, as well as distinction between P. falcozi and its relative P. azurea Fallén (Diptera: Calliphoridae). The material was sampled in the National Nature Reserve Šúr (SW Slovakia) from nests of the tree sparrow (Passer montanus), which has not previously been classified as a host of P. falcozi. Knowledge of diagnostically relevant characterics to determine bird blowfly larvae and puparia will undoubtedly contribute to the current accepted phylogeny and classification of the genus Protocalliphora.

The Fedrizziidae are the most diverse group of mites associated with passalid beetles in Australia. Herein, I re-diagnose the family, genera and species, and describe ten new species from Australia, Indonesia and Thailand: Fedrizzia abradoalves sp. nov., F. gilloglyi sp. nov., F. parvipilus sp. nov., Neofedrizzia bunyas sp. nov., N. gordoni sp. nov., N. helenae sp. nov., N. imparmentum sp. nov., N. janae sp. nov., N. lepas sp. nov. and N. sulawesi sp. nov. Fedrizzia strandi (Oudemans), Neofedrizzia leonilae Rosario & Hunter, Neofedrizzia tani Pope & Chernoff and Neofedrizzia vitzthumi (Oudemans) are re-described. Neofedrizzia bicornis Karg is a junior synonym of Neofedrizzia scutata Womersley, which is also transferred to Fedrizzia. Fedrizzia unospina Karg is a junior synonym of Fedrizzia carabi Womersley. Fedrizzia gloriosa Berlese is transferred to Neofedrizzia. The specimens described by Womersley as Fedrizzia sp. cf. grossipes represent specimens of Fedrizzia sellnicki Womersley. Parafedrizzia buloloensis Womersley is recorded from Australia for the first time. A key to adult male and female Fedrizziidae and a summary of host records is provided.

Molecular Phylogenetic

The genus Nephrocytium Nägeli is a common member of phytoplankton communities that has a distinctive morphology. Its taxonomic position is traditionally considered to be within the family Oocystaceae (Trebouxiophyceae). However, research on its ultrastructure is rare, and the phylogenetic position has not yet been determined. In this study, two strains of Nephrocytium, N. agardhianum Nägeli and N. limneticum (G.M.Smith) G.M.Smith, were identified and successfully cultured in the laboratory. Morphological inspection by light and electron microscopy and molecular phylogenetic analyses were performed to explore the taxonomic position. Ultrastructure implied a likely irregular network of dense and fine ribs on the surface of the daughter cell wall that resembled that of the genus Chromochloris Kol & Chodat (Chromochloridaceae). Phylogenetic analyses revealed that Nephrocytium formed an independent lineage in the order Sphaeropleales (Chlorophyceae) with high support values and a close phylogenetic relationship with Chromochloris. Based on combined morphological, ultrastructural and phylogenetic data, we propose a re-classification of Nephrocytium into Sphaeropleales, sharing a close relationship with Chromochloris.

We report upon eleven species of thecate hydroids collected during a recent scientific expedition to the North Patagonian Zone between southern Chiloé and Puyuguapi fjord/ Magdalena Island. One species belongs to the family Haleciidae Hincks, 1868, four to the family Sertulariidae Lamouroux, 1812, and six to the family Campanulariidae Hincks, 1868. Of them, Halecium cymiforme Allman, 1888 and Symplectoscyphus leloupi El Beshbeeshy, 1991 are redescribed based on new, fertile material. Sertularella allmani Hartlaub, 1901 is assigned to the synonymy of S. antarctica Hartlaub, 1901. Campanularia subantarctica Millard, 1971 is considered as a junior synonym of C. lennoxensis Jäderholm, 1903, and data on both the male and female gonothecae are provided. A variant of Clytia gigantea (Hincks, 1866) with smaller hydrothecae than usual is described. Sertularella sanmatiasensis El Beshbeeshy, 1991 is recorded from Chile for the first time. Although not belonging to the present collection, several notes on Kirchenpaueria curvata (Jäderholm, 1904) are provided.
