Eurycyphon sp. A

Material examined: 1 ♀: NE QLD, Mt Demi, 7 km SW of Mossman, 24.Oct. 1983, 110m, D. Yeates & G.Thompson, Pyrethrum rainforest ( QMSB).

Habitus. BL 2.6mm, BL/BW ~1.4. Occiput dark brown, frontoclypeus, pronotum and scutellum reddish brown. Elytra cinnamon-coloured. Lower side and legs dark reddish. The elytra have been somewhat dislocated, overlapping along the caudal portion of suture. Therefore, the caudal portion of body contour seems to narrow considerably. Punctures on head fine, indistinctly granular. Pronotum with finer normal punctures, those on elytra even finer. Antenna: fairly slender, antennomere 3 not shorter than pedicel but narrower. Distal antennomeres are approximately 2x longer than wide.

Female. The genitalia are similar to E. perlatus but there are no microtrichia surrounding the prehensor. It consists of a sclerotized hull in which 2 ridges with a few sharp teeth are located. Details not visible.

Notes. This is the female of an unknown species. It is not named because the genitalia are not sufficiently visible, clearing was only partly successful. By size and shape, it resembles two species from which it differs as follows: E. perlatus differs by strong granular punctation on head and pronotum; E. castaneus differs by the large, deep punctures on the elytra.
