Cratyna (Diversicratyna) adulterina Mohrig & Kauschke sp. n.

(Fig. 3 A–B)

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

Holotype: Male, 8.viii.1997, Malaise trap, leg. J. Seymour (PWMP).

Description. Male. Head. Yellowish-brown. Eye bridge 4 facets wide. Antennal flagellomeres with short dense hair, rather short necks; 4th flagellomere with l/w index of 2.2, neck ¼ of the length of the basal node, brownish and darkened at the tip; with hairs shorter than the diameter of the basal node. Palpus short, 2-segmented; basal segment with 1–2 bristles. Thorax. Brown with yellow spots on the scutum and pleural sclerites. Scutum with rather short hairs and some longer lateral bristles; scutellum with short hairs and with 4 longer marginal bristles. Postpronotum with a few short hairs. Wing brownish, R1 = R, joining C at the level of the M-fork; R5 with ventral macrotrichia in the distal third; y = x, without macrotrichia; posterior veins without macrotrichia. Haltere rather long, brown. Legs yellowish, tarsi darkened; legs rather long and thin; fore tibia with a dense patch of brownish bristles at the inner apex; spurs of middle and hind tibiae equal and much longer than the diameter of the apex; claws without teeth. Abdomen. Tergites brown, sclerites yellow. Hypopygium brownish; gonocoxites somewhat longer than gonostylus, without a distinct long robust bristle on the ventral apex, the inner ventral margin with rather sparse hairs; gonostylus narrowed to the apex, with a long apical tooth and 4 shorter hyaline spines (two above and two below the tooth). Tegmen laterally curved, without any inner structure. Aedeagus short. Body length: 3.4 mm.

Comments. Cratyna adulterina sp. n. is similar to Cratyna unispinula (Mohrig & MenZel, 1992) from Germany. It is characteriZed by a 2-segmented palpus, a rather long-stalked haltere and a narrow gonostylus with a long apical tooth and four hyaline spines. The subgenus Diversicratyna was established for Palaearctic species and differs mainly from other Cratyna subgenera by a narrow elongate gonostylus with a rather strong apical tooth, surrounded by a few shorter spines. The Zoogeographic distribution of the subgenus is not clear yet and requires further investigation, particularly in relation to the fauna of the Oriental region.

Distribution. Australia, Queensland.
