Eye minutely pilose; proboscis longer than head height; body black (with faint blue iridescence in western population); antennae red-brown to black; parafacial with marginal pile; postpronotal lobe concolourous with rest of thorax; femora black with pale apices, rest of leg dark yellow to white with black on tibiae; abdomen red or yellow laterally; distiphallus broad apically. Redescription. Body length: 9.5-12.5 mm (male), 11.0-14.0 mm (female). Head with eye sparsely pilose with minute setae (appears apilose); ocellar tubercle raised laterally or relatively flat; medial ocellus reduced; occiput brown-black, occipital pile white, sparse; postocular ridge and gena overlain with grey pubescence; clypeus length equal to oral cavity, brown-black; palpus white or yellow; margin of oral cavity (parafacial) pilose; proboscis longer than head height; flagellum red-brown to black; scape and pedicel brown. Thorax with postpronotal lobe brown-black; scutum black, scutal vestiture dense white pile; scutellum black; pleuron black (thorax with slight bluish iridescence in western populations); coxae black; femora black or brown-black, apices dark yellow; tibiae predominantly black with dark yellow to white (apically); tarsi dark yellow to white; lower calypter white, with yellow margin; wing hyaline (male) or slightly infuscate (female); venation dark; vein R4 with spur vein, rarely without. Abdomen shape rounded globose, much larger than thorax, colour highly variable, orange-red to yellow, dark markings anteriorly and medially, or dark yellow, brown anteriorly on tergites 2-6, vestiture as extensive short white-silver pile, longer laterally.

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 ( Neboiss 1971 ). Western Australian individuals have more reddish colouration laterally on the abdomen, particularly in males, and the body has a bluish iridescence (Fig. 1). This bluish iridescence is not seen in specimens from eastern states.
