Austrosciara Schmitz & Mjöberg, 1924, a senior synonym of Ctenosciara Tuomikoski, 1960 (Diptera: Sciaridae) and the description of a new brachypterous species in the genus Author Mohrig, Werner Author Kauschke, Ellen Author Heller, Kai text Zootaxa 2017 2017-11-07 4344 2 357 366 journal article 31609 10.11646/zootaxa.4344.2.10 12425c73-75f8-47da-ad1d-72ccbdc74a06 1175-5326 1042976 385A5F6E-8868-46C1-9099-3DBBFAF9EE48 Austrosciara pedibusa sp. n. ( Fig. 4 A‒E ) Locus typicus : Australia , Victoria , Central Highlands , Donna Buang Road , 1 km SW of Mt Donna Buang , 37° 43’S , 144°40’16’’E , Nothofagus cunninghamii forest. Holotype : Female, 29.xi.1994 ‒ 20.i.1995 ; pitfall trap , leg. G. Milledge (NMV). Paratypes : 2 females , same data as holotype ( PWMP , PKHH ). Description . Female. Head . Eye bridge 2‒3 facets wide. 4th flagellomere with l/w-index of 1.8, with brown and sparse bristle-like hairs, somewhat longer than the width of the basal node; a few curved hyaline sensilla-like hairs in between. Necks rather long. Palpi short, 3-segmented; basal segment large, having a deep sensory pit with long sensillae and 1 bristle. Thorax . Brownish, the pleural sclerites are nearly normal in shape, and not reduced or fused. Scutum with dark, short and fine hairs. Wing strongly reduced, half as long as the thorax, scale-shaped (in lateral view rod-like). Haltere short, strongly reduced, misshapen. Legs brownish; apex of the fore tibia with a comb-like undivided row of 4‒5 hyaline bristles; middle and hind tibia with equally long spurs, as long as the diameter of the tibial apex; tarsus with somewhat shortened segments; claws toothless. Abdomen . Brown, with rather long and sparse dark hairs. Body size: 1.6 mm . Comments . The species is characterized by a 3-segmented palpus with a deep sensory pit on the basal segment and short antennal flagellomeres. The deep sensory pit with long sensillae distinguishes females of Aus . pedibusa sp. n. from the two other brachypterous species ( Aus. termitophila and Austrosciara sp.). We consider this character suitable to identify male specimens of Aus. pedibusa sp. n. , but they are unknown to us so far.
