Scatopsciara dubiosa Mohrig & Kauschke sp. n.

( Fig. 19 A–E)

Type locality: Australia, Queensland, Mt Lewis , 37 km WSW of Port Douglas, 16°35´S, 145°16´E.

Holotype: Male, 13.vi.1997, wet forest, Malaise trap, leg. J. Seymour (PWMP).

Paratypes: 1 male, 13.vi.1997; 1 male, 8.viii.1997, type locality, same data ( PWMP; 1 male in ANIC).

Description. Male. Head. Brown. Eye bridge 3 facets wide. Antenna brown, scape and pedicel somewhat paler; 4th flagellomere with l/w index of 2.0, hairs as long as the diameter of the basal node, neck about 1/4 of the length of the basal node. Palpus rather long, 3-segmented, basal segment with one bristle and a patch of sensillae. Thorax. Brown. Scutum with rather short pale hairs, some dorsocentral and lateral bristles stronger; scutellum with 2 long marginal bristles. Postpronotum bare. Wing broad and pale; R1 short, = 1/2 R; R5 short and without ventral macrotrichia; C = 2/3 w; y shorter than x, without macrotrichia; posterior veins without macrotrichia. Haltere short and darkened. Coxae and femora yellowish, tibia and tarsi darkened; fore tibia at the inner apex with an irregular row of bristles, proximally weakly bordered; middle and hind tibia with two unequal spurs. Claws toothless. Abdomen. Brown. Hypopygium brown; gonocoxite ventrally with a long, strong bristle and with sparse short hairs on the inner margin; gonostylus narrow, at the apex with 2 short and somewhat unequal spines. Tegmen wider than long, apically rounded. Aedeagus short and robust. Body length: 1.2 mm.

Comments. The species is characteriZed by unequal spurs on the middle and hind tibia and an irregular row of bristles on the apex of the fore tibia, with a semicircular border proximally. This structure is unusual for species of Scatopsciara , but all other characters are in accordance with this genus. Gonostylus elongate with 2 unequal apical spines. The species is currently left unplaced in Scatopsciara .

Distribution. Australia, Queensland.
