Review of the stiletto fly genus Actenomeros Winterton & Irwin (Diptera, Therevidae, Agapophytinae)

The endemic Australian genus Actenomeros Winterton & Irwin, 1999b is reviewed. Three species are transferred from Nanexila Winterton & Irwin, 1999a: Actenomeros aureilineata (Winterton & Irwin, 1999a) comb. n., Actenomeros intermedia (Winterton & Irwin, 1999a) comb. n. and Actenomeros paradoxa (Winterton & Irwin, 1999a) comb. n. A new species (Actenomeros budawangsp. n.) is described and figured from New South Wales. A key to species is presented.     

New species of Vomerina Winterton (Diptera, Therevidae, Agapophytinae) from Australia

Two new species of Vomerina Winterton, 2007 (Vomerina comapenissp. n. and Vomerina micorasp. n.) are described from New South Wales (Australia).     

The phylogeny of stiletto flies (Diptera: Therevidae)

The therevoid clade represents a group of four families (Apsilocephalidae, Evocoidae, Scenopinidae and Therevidae) of lower brachyceran Diptera in the superfamily Asiloidea. The largest of these families is that of the stiletto flies (Therevidae). A large‐scale (i.e. supermatrix) phylogeny of Therevidae is presented based on DNA sequence data from seven genetic loci (16S, 18S and 28S ribosomal DNA and four protein‐encoding genes: elongation factor 1‐alpha, triose phosphate isomerase, short‐wavelength rhodopsin and the CPSase region of carbamoyl‐phosphate synthase‐aspartate transcarbamoylase‐dihydroorotase). Results are presented from Bayesian phylogenetic analyses of approximately 8.7 kb of sequence data for 204 taxa representing all subfamilies and genus groups of Therevidae. Our results strongly support the sister‐group relationship between Therevidae and Scenopinidae, with Apsilocephalidae as sister to Evocoidae. Previous estimates of stiletto fly phylogeny based on morphology or DNA sequence data, or supertree analysis, have failed to find significant support for relationships among subfamilies. We report for the first time strong support for the placement of the subfamily Phycinae as sister to the remaining Therevidae, originating during the Mid Cretaceous. As in previous studies, the sister‐group relationship between the species‐rich subfamilies Agapophytinae and Therevinae is strongly supported. Agapophytinae are recovered as monophyletic, inclusive of the Taenogera group. Therevinae comprise the bulk of the species richness in the family and appear to be a relatively recent and rapid radiation originating in the southern hemisphere (Australia + Antarctica + South America) during the Late Cretaceous. Genus groups are defined for all subfamilies based on these results.     

Iranotrichia gen. n., a new genus of Scenopinidae (Diptera) from Iran, with a key to window fly genera of the world

An unusual new genus of Scenopinidae, Iranotrichia gen. n., comprising two newly discovered species (Iranotrichia insolita sp. n. and Iranotrichia nigra sp. n.), is described from Iran. Iranotrichia gen. n. are scenopinine window flies with a habitus reminiscent of certain bee fly genera (Bombyliidae), based on colouration and elongate mouthparts and antennae. The phylogenetic placement of this distinctive new genus is discussed and a dichotomous key to world genera is presented. The genus name Kelseyana nom. n. is proposed to replace Caenoneura Kröber, 1924, which was found to be preoccupied by Thomson (1870: 270) (Hymenoptera) and Kirby (1890: 136) (Odonata).     

Phylogenetic revision of the Taenogera Kröber genus-group (Diptera: Therevidae), with descriptions of two new genera

The phylogenetic relationships of the Taenogera genus-group, consisting of nine genera, are examined using cladistic methods. Twenty-one species representing nine genera and one outgroup were compared in a cladistic analysis across 99 states in 44 characters. The genus Taenogera Kröber is revised to contain only T. longa (Schiner), T. nitida (Macquart) and T. notatithorax Mann. Two new genera are described and figured: Actenomeros gen. n., with two species, A. corniculaticaudus sp. n. and A. onyx sp. n.; and Taenogerella gen. n., with four species, Ta. elizabethae sp. n., Ta. platina sp. n., Ta. schlingeri sp. n. and Ta . nigrapicalis (Mann) comb. n. Phylogenetic analysis also supports the removal of Nanexila gracilis (Mann) comb. n. from Taenogera .

New genera of philopotine spider flies (Diptera, Acroceridae) with a key to living and fossil genera

Information on the three previously described species of Halocoryza Alluaud is updated and a new species for the genus from Isla Carmen, Sea of Cortés, Baja California Sur, México is described. Halocoryza whiteheadianasp. n. was found at UV light on a beach of that island. This species does not fit the profile of the other three species, i.e., living on coralline beach sands, or in the Mangrove intertidal zone. Two alternative possibilities as to why this is so are suggested and a study plan for testing these possibilities is proposed.     

A new species of spider fly in the genus Sabroskya Schlinger from Malawi, with a key to Acrocerinae world genera (Diptera, Acroceridae)

A most remarkable new genus of scuttle fly (Diptera: Phoridae) from Sulawesi

ABSTRACT. Postoptica platypezoidea gen.n., sp.n. from Sulawesi is described. It shows no obvious affinity with any known genus. Its superficially platypezid like appearance and other apparently plesiomorphic features are interpreted as secondary and convergent.     

A new species of Ocydromia Meigen from China,with a key to species from the Palaearctic and Oriental Regions (Diptera,Empidoidea, Ocydromiinae)

Previously only one species of the genus Ocydromia Meigen was recorded from China. Here a second species of the genus from China, Ocydromia shanxiensis sp. n., is reported. A key to the species of the genus from the Palaearctic and Oriental regions is presented.     

A new genus of Chlidanotini (Lepidoptera, Tortricidae) from New Caledonia, with a key to genera and check-list of species

Abstract Iconostigma gen.n., with included species tryphaenu sp.n. (typespecies) and morosa sp.n., is described from New Caledonia. A key to males of the world genera and a check-list of the world species of Chlidanotini are provided. The relationship of the Chlidanotini to the Polyorthini and Hilarographini is discussed, with particular reference to Iconostigma . It is suggested that the hair-pencils of the eighth abdominal segment, and the invaginations in the male valvae into which each hair-pencil is inserted, are apomorphic characters which unite these three tribes. Panegyru Diakonoff is transferred to the Tortricini and Polemograptis flavicostana (Walsingham) is transferred to Panegyra , comb.n. Archimaga euplocamis Meyrick is synonymized with Metrernis ochrolina Meyrick, syn.n.     

A new genus and a new species of Siricinae (Insecta, Hymenoptera, Siricidae) from India with a revised key to its world genera

Neoxeris gen.n. (type species: Neoxeris melanocephala sp.n.) from India is described and illustrated. Neoxeris is related to Sirex Linnaeus and Xeris Costa from which it is distinguished. A revised key to the world genera of Siricinae is provided.     

New species of Prepseudatrichia Kelsey from Thailand (Diptera, Scenopinidae)

A new genus of fossil Mymaridae (Hymenoptera) from Cretaceous amber and key to Cretaceous mymarid genera

Myanmymar aresconoidesgen n., sp. n. is described from one female in Burmese amber, dated as about 100 my. It is similar to Arescon on wing features but is unique among Mymaridae in having distinctly segmented palpi. It is the fifth mymarid genus definitely referable to the Cretaceous period. A key to Cretaceous mymarid genera is presented and the features of Myanmymar are compared with the other Cretaceous and extant mymarid genera.     

A new genus and species of hypodermatine bot flies (Diptera: Oestridae)

The bot fly Gruninomyia mira Szpila & Pape, gen.n. , sp.n. is described from Iran, North Khorasan, based on a single adult male and with no larval or host data. The monotypic genus shows a mixture of features otherwise found in either the rodent/lagomorph‐parasitizing oestromyine clade (Oestroderma + Oestromyia) or the artiodactyl‐parasitizing hypodermatine clade (Hypoderma + Pallasiomyia + Pavlovskiata + Przhevalskiana + Strobiloestrus) of subfamily Hypodermatinae. A morphology‐based phylogenetic analysis is marginally in favour of a position of Gruninomyia Szpila & Pape, gen.n. as sister taxon of (Oestroderma + Oestromyia). The COI barcode sequence is provided for the new species, and a phylogenetic analysis based on this marker for Oestridae retrieved from GenBank is in agreement with the conclusions based on morphological data.
