The identity of Ewartia oldfieldi (Distant) is re-examined and this species is redescribed. Five new species belonging to the genus Ewartia Moulds are described. Ewartia oldfieldi s. str. occurs in association with wattles (Acacia spp.; Mimosaceae) with large or fleshy phyllodes growing in soils derived from sandstone and coarse-grained metasediments throughout the south-eastern third of Queensland. Ewartia roberti n. sp. is associated with wattles that possess narrow or delicate phyllodes, growing in loam soils in southern Queensland and northern New South Wales. Ewartia lapidosa n. sp. occurs in dryer inland and semi-arid areas between Croydon in northern Queensland and the Capertee Valley in central New South Wales where it occurs on various wattles growing in hard, rocky soils, including those derived from laterite and sandstone. Ewartia etesia n. sp. occurs principally on wattles growing along drainage lines in the Top End of the Northern Territory and the eastern edge of the Kimberley in Western Australia. Ewartia thamna n. sp. occurs in low, shrubby vegetation (presumably on wattles) in gravelly soils on low rises and along floodplains at the southern edge of the Top End in the Northern Territory. Ewartia carina n. sp. occurs in transitional habitats with tropical rainforest elements on the eastern edge of Cape York Peninsula in north Queensland. The distinctive, sometimes variable and typically complex calling songs specific to each of the species are illustrated and documented as part of these descriptions and comparisons.

Fossil phorid flies display various levels of morphological change that are correlated with myrmecophily (association with ants) and termitophily (association with termites) in the modern fauna. Three discrete episodes in the evolution of limuloidy, a defensive body form, are documented from Eocene Baltic amber. Extinct fossil stem-group taxa of the modern myrmecophilous genus Aenigmatias Meinert are described, with three new species – A. longicornis sp. nov., A. primitivus sp. nov. and A. nigeroticus sp. nov. – recognized and illustrated. Protoplatyphora Brues is synonymized with Aenigmatias, with its single previously described species, A. tertiarius (Brues), considered a new combination. Chaetopleurophora bisetosa Brown, 2007 is transferred to Aenigmatias as A. bisetosus (comb. nov.). An unrelated Aenigmatias-like fossil is described as Pseudaenigmatias ctenitibia gen. et sp. nov., and belongs to a modern termitophilous clade. Limulomyia tyche Brown, 1999 is interpreted as a separate, already highly limuloid lineage not related to either of the other two limuloid groups. A key to fossil Aenigmatias is given, along with a phylogenetic analysis of fossil taxa. Fossil specimens have profound implications for our knowledge of the evolution of the limuloid body form found in modern species of Aenigmatias. http://zoobank.org/urn:lsid:zoobank.org:pub:DE779D49-7636-4B1D-9F7D-CF3FF6D3CE97 © 2016 The Trustees of the Natural History Museum, London 2016.

A new fossil species of the genus Anevrina Lioy is described from 40 million-year-old Baltic amber. It differs from the only other described fossil species of this genus, Anevrina oligocoenica Brues, by the setation of the tibiae and the structure of the male genitalia. The new species is most similar to the extant Anevrina olympiae (Aldrich), from which it differs by the darker color and details of the male genitalia. © 2013 Entomological Society of America.

The phylogeny of the bee-killing flies, genus Melaloncha Brues (Diptera: Phoridae) is analysed using six genes - cytochrome oxidase I, 16S ribosomal DNA, 12S ribosomal DNA, NADH1 dehydrogenase, 28S ribosomal DNA and CAD- plus 47 morphological characters. A total of 91 specimens, including eight out-groups and 83 Melaloncha (representing 70 species) were included in the analyses. Parsimony analysis of the combined data set produced a single most parsimonious tree with varied Bremer and bootstrap support of interior nodes. Bayesian analysis of molecules only and of morphology + molecules produced trees largely in agreement with parsimony results, although with a few differences. Supported groups included subfamily Metopininae, genus Melaloncha, and subgenera Melaloncha s.s. and Melaloncha (Udamochiras) Enderlein. Within the subgenera, the previously recognized Melaloncha furcata, Melaloncha cingulata, Melaloncha ungulata and Melaloncha stylata groups were recovered, as well as some new groupings. The M. furcata group was placed as the sister group of other Melaloncha s.s., which is consistent with known host-attacking behaviour. © 2010 The Authors.

The ambrosia beetle Xyleborinus andrewesi (Blandford) is recorded from North America for the first time. It was reared from a section of sugar apple (Annona squamosa L.) collected in North Fort Myers, Lee Co., Florida.

Recording and describing animal 'monsters' collected in the field can still contribute to progress in developmental biology despite the uncontrolled conditions the specimen experienced throughout development. Comparison with model organisms and a sound phylogenetic analysis may offer a tentative explanation for the underlying developmental mechanism and suggest new targets for experimental studies. We describe a female specimen of the anthomyiid fly Hydrophoria sp. with an ectopic macrochaeta in the left eye and suggest tentative interpretations, including one in terms of a local expression, or derepression, of a proneural gene. The anthomyiid lineage has been estimated to have split ca. 65 million years ago from the dipteran clade containing Drosophila and ca. 140 million years ago from the clade containing Megaselia. © 2012 Springer-Verlag Berlin Heidelberg.

A simple light trap for collecting small insects, especially Diptera, is described. Some extraordinary specimens collected by this type of trap are noted.


The species of the New World genus Apocephalus are parasitoids, mostly of ants, and many undescribed species exist. Here, the Apocephalus mucronatus group species are revised, with five new to science described: A. longimanus, A. longimucrus, A. missouriensis, A. setissitergus, and A. weissi. Along with the previously known two species, Apocephalus mucronatus Borgmeier and Apocephalus mesacanthus Brown & Lebrun, these form a well-defined monophyletic group based on the presence of a spinelike protrusion on the oviscape, distinctly sclerotized posterolateral membrane on intersegment 7-8, and other female characters. Life history data are known for only one species, which is a parasitoid of Camponotus carpenter ants. Copyright © 2012 · Magnolia Press.

A new species of phorid fly, Euryplatea nanaknihali (Diptera: Phoridae), is described from Thailand. This is the first Oriental Region record for this genus; it is otherwise known only from the type species from Africa, where it parasitizes ants of the genus Crematogaster Lund. The new species is probably capable of parasitizing the smallest host Crematogaster (Formicidae) ants in its range. At 0.40 mm in body length, it is the smallest known fly in the world. © 2012 Entomological Society of America.


Hydrellia lagarosiphon sp. n. is described from adult male, female, ovum, third instar larva and puparium from cultured material originating from that reared from Lagarosiphon major in South Africa. Its related species, Hydrellia bicolorithorax Giordani Soika, 1956, is partially redescribed from type material from Rwanda.
