Austrosciara kalliesi sp. n. *

( Fig. 2 A–D )

Type locality: Australia, New South Wales, Candelo (near Bega ).

Holotype: Male, 17.–24.xii.1993, leg. A. Kallies (ANIC).

Paratype: 1 male, same data ( PWMP).

Description. Male. Head. Brown. Eye bridge 4 facets wide. Antenna brownish; 4th flagellomere with l/w index of about 2.4, with pale hairs somewhat longer than the diameter of the basal node; necks rather long. Palpus 3- segmented, pale, basal segment with 1-3 bristles and a flat patch of sensillae. Thorax. Yellowish-brown. Scutum with short hairs, some lateral and prescutellar bristles longer; scutellum with 4 longer marginal bristles; postpronotum bare. Wing pale; R1 = 1/2 R; R 5 in the distal third with ventral macrotrichia; C weakly longer than 1/ 2 w; y = x and without macrotrichia; posterior veins with macrotrichia. Haltere short and bright. Coxae and legs yellowish, tarsi darkened; apex of fore tibia with a broad comb of hyaline bristles, one bristle isolated; spurs of middle and hind tibiae equal in size, longer than the diameter of the apex; claws without teeth. Abdomen. Brownish, with rather sparse fine hairs. Hypopygium brown, the ventral base wide and v-shaped; gonocoxites at the inner ventral margin with sparse hairs; gonostylus rather short, pointed to the apex and weakly darkened, apically with a rather robust tooth and 4–5 short spines in the distal third. Tegmen broader than long, flat and pyramid-like. Aedeagus rather long and thin. Body length: 2.2 mm.

Comments. The species is characterized by having macrotrichia on all posterior wing veins, brownish antenna, claws without teeth and a rather short gonostylus with an apical tooth and 4–5 shorter spines in the distal third of the inner side.

*The species is named after Dr. Axel Kallies, who graduated from the Ernst-Moritz-Arndt University Greifswald, Germany and collected sciarids during an excursion throughout Australia. Professor Kallies is currently with the Department of Microbiology and Immunology at the Peter Doherty Institute for Infection and Immunity, The University of Melbourne. The authors are very thankful to him for obtaining this material to study.

Distribution. Australia: New South Wales.
