The Australasian spider flies (Diptera: Acroceridae) are reviewed, with all eight currently recognized genera diagnosed and figured. The panopine genus Panops Lamarck, 1804 from Australia and Indonesia is revised with four new species described, increasing the total number of species in the genus to nine: Panops aurum sp. n., Panops danielsi sp. n., Panops jade sp. n. and Panops schlingeri sp. n. Five species of Panops are redescribed: Panops austrae Neboiss, 1971, Panops baudini Lamarck, 1804, Panops boharti (Schlinger, 1959), comb. n., Panops conspicuus (Brunetti, 1926) and Panops grossi (Neboiss, 1971), comb. n. The monotypic genera Neopanops Schlinger, 1959 and Panocalda Neboiss, 1971 are synonymized with Panops. Keys to genera of Australasian Acroceridae and species of Panops, Helle Osten Sacken, 1896 and Australasian Pterodontia Gray, 1832 are included.
cybertaxonomy, spider parasitoid
Spider flies (also known as small-headed flies) (Diptera: Acroceridae) are a distinctive group of lower brachyceran flies characterized by unusual adult body shape and highly specialized larval biology as parasitoids of spiders. Adults are recognized as important pollinators of angiosperms (Fig. 1), frequently as strong fliers with greatly elongate mouthparts for feeding in long corolla flowers, although some species have reduced or even vestigial mouthparts`(

The Australasian acrocerid fauna comprises all three subfamilies, although represented by relatively few genera. Two acrocerine genera (Ogcodes Latreille, 1797 and Pterodontia Gray, 1832) are found throughout the region, and are considered cosmopolitan throughout all major biogeographic regions. Philopotinae are represented by an endemic genus in New Zealand (Helle Osten Sacken, 1896) (
Panopinae are well represented in the Australasian region.Six genera are described previously from New Zealand (Apsona Westwood, 1876), Indonesia (Neopanops Schlinger, 1959) and Australia (Panocalda Neboiss, 1971, Panops Lamarck, 1804, Mesophysa Macquart, 1838 and Leucopsina Westwood, 1876) (

Apsona is a monotypic genus endemic to New Zealand and can be readily differentiated from all other Panopinae based on the lack of tibial spines. Apsona shows little relationship to the rest of the Australasian Panopinae and shows remarkable similarity to the New World genus Eulonchus Gerstaecker, 1856, sharing numerous characteristics such as metallic green colouration, antennal shape, dense eye pilosity, elongate mouthparts, eyes contiguous below antennal base and absence of an alula (

Leucopsina is an endemic Australian genus of contrastingly coloured yellow and black flies, with distinct sexual dimorphism between males and females; male having more pronounced constriction of the abdomen anteriorly. The body colouration, darkening of the costal wing margin and abdominal waist allows members of this genus to be convincing wasp mimics (

Mesophysa is an endemic eastern Australian genus closely related to Leucopsina. They share a similar habitus with narrowing of the abdomen anteriorly (more pronounced in Leucopsina), apilose eyes, infuscate wings and flagellum shape, as well as the crossvein 2r-m joining to R5 rather than to the stem R4+5. This genus can be differentiated from Leucopsina by the lack of black and yellow markings. Mesophysa has been considered a synonym of Panops by some authors (

Panops is the type genus for the subfamily Panopinae and includes some large metallic coloured species. The genus is endemic to Australia and neighbouring Papua region of Indonesia. The original concept of the genus was expanded to include species from the New World by some authors, but these have subsequently been placed in the separate and distantly related genus Lasia Wiedemann, 1824 (e.g. Lasia metallica Rondani, 1863; Lasia ocelliger (Wiedemann, 1830)).

The type for the genus, Panops baudini is the most commonly represented species in collections. This species is distributed in Queensland, New South Wales, Victoria and Western Australia. The apex of the aedeagus is broad and quadrangular in this species (Fig. 17) while in all other species it is much narrower. The record from Tasmania is apparently erroneous (

Panops conspicuus is recorded from arid regions of southwest Western Australia and Western Victoria. There is dramatic sexual dimorphism in both body colouration and shape in this species, with males very similar to species of Mesophysa. Panops conspicuus can be differentiated from other Panops species by the bright yellow postpronotal lobes, elongate mouthparts, yellow and brown colouration (female), and apilose eyes. Females of this species are similarly coloured to females of Panops grossi comb. n., a species which also displays dramatic sexual dimorphism.

This beautifully coloured species is named after my daughter, Jade Tanya Winterton, whose name also describes the deep green colouration found in this species.
Panops jade sp. n. is a distinctive species with extensive green to blue-violet iridescence, particularly in the female. It is similar to the western Australian species, Panops austrae, but is distinguished by the length of the mouthparts, leg colour and different vestiture pattern on the abdomen. Panops jade sp. n. is known only from Isla Gorge National Park in southern Queensland. Both males and females are recorded from Spinifex grass (Triodia sp.), presumably at rest.

Pterodontia is a cosmopolitan genus containing 19 valid species, three of which are recorded from the Australasian region (
Some species of Pterodontia have greatly enlarged and sclerotized lower calypters, appearing somewhat like a second pair of wings (e.g. Pterodontia davisi). Males in this genus typically have sclerotized projections on the costal margin of the wing. Characteristics which diagnose this genus from other acrocerids include head very small relative to thorax width, tibial spines present, cells m3, d and basal r4+5 fused to form a single cell, eyes densely pilose, antennae adjacent to the ocellar tubercle and mouthparts reduced. Contrary to other authors, Pterodontia has been placed previously in Panopinae by
