( Fig. 20 A–B)

Type locality: Australia, Queensland, Palm Cove, near Cairns , mangrove forest along the coastline. Holotype: Male, 3.vii.2000, caught by net, leg. W. Mohrig ( PWMP).

Description. Male. Head. Brown. Eye bridge 3 facets wide. Antenna dark brown; 4th flagellomere with l/w index of 3.0, with a few curved hyaline sensoria-like bristles between somewhat long appressed hairs, neck dark brown and about 1/5 of the length of the basal node. Palpus 3-segmented, basal segment large, with 2 bristles and short sensillae. Thorax. Dark brown. Scutum with very short hairs, short lateral bristles; scutellum with 4 short marginal bristles; Postpronotum bare. Wing pale, with very distinct posterior veins; R1 short, = 1/3 R; R5 without ventral macrotrichia; C = 2/3 w; y very short, = 1/ 3 x, without macrotrichia; M-fork narrow; Cu-stem short, CuA2 rather strongly curved; posterior veins without macrotrichia. Haltere short and darkened. Legs brown; fore tibia with a very broad comb-like row of paler bristles at the inner apex; middle tibia with two short unequal spurs, hind tibia with one short spur only. Claws large and strongly curved. Abdomen. Brown, with fine sparse hairs.

Hypopygium brown; gonocoxite with a rather short strong bristle on the ventral apex, with sparse hairs ventrally but rather long at the inner margin; gonostylus short and compact, with a strong apical tooth and an irregular row of 6 spines in the distal third. Tegmen large, wider than long, with a small area of fine teeth. Aedeagus very short, furca large and strongly sclerotiZed. Body length: 2.2 mm.

Comments. The species is characteriZed by a strong apical tooth and 6 subapical spines in the distal third of the gonostylus, a large and broad tegmen and a short aedeagus with a large furca. It belongs to the Scatopsciara atomaria group and is similar to species of the Palaearctic region.
