Scaphobaeocera lycocorax sp. n.

( Figs 8-12)

Type material. Holotype ♂: PAPUA NG Morobe Bulldog Rd, MtNaiko 2750m, 29.VI.1992 G. CUCCODORO # 25B ( MHNG). Paratype: 1 ♂, with the same data as the holotype ( MHNG).

Description. Length 1.40-1.45 mm, width 0.78-0.80 mm, dorsoventral diameter 0.85-0.87 mm. Head, most of body, femora and tibiae dark reddish-brown or blackish. Apical abdominal segments light brow or yellowish. Tarsi slightly lighter than tibiae. Antennae light brown or yellowish. Length/width ratios of antennomeres as: III 25/8: IV 35/9: V 45/10: VI 33/10: VII 50/14: VIII 32/12: IX 50/18: X 48/22: XI 65/25. Pronotum very finely punctate, with hardly visible trigulate microsculpture. Visible tip of scutellum minute. Elytra with traces of parasutural striae, sutural striae shallow, barely curved near base, discal punctation as fine or almost as fine as pronotal punctation, strigulate microsculpture distinct, not iridescent. Hypomera not microsculptured, appearing smooth, lacking longitudinal stria. Middle area of metaventrite flattened, without median stria or impression, smooth in middle, punctation dense and coarse laterally smooth middle with punctures larger than puncture intervals, punctures posterior smooth middle smaller than puncture intervals, pubescence short. Lateral parts of metaventrite very finely punctate, with strigulate microsculpture. Submesocoxal areas about 0.03 mm, submesocoxal lines distinctly punctate. Metanepisterna about 0.05- 0.07 mm wide, flat, not or slightly narrowed anteriad, impunctate, with straight suture reaching metepimera. Tibiae straight. Abdomen with strigulate microsculpture, not iridescent; sternite 1 very finely punctate, with basal punctures coarse.

Male: Protarsomeres slightly 1 to 3 widened, narrower than apices of protibiae. Aedeagus as in Figs 8-11, 0.48 mm long.

Etymology. The species epithet is a noun, the scientific generic name of the paradise crow. Differential diagnosis. This species is similar with S. papuana . It differs in external characters by the by the larger body, larger submesocoxal areas and longer antennae, in particular by the antennomere V much longer than VI. Both species may be easily distinguished by their aedeagal characters: S. lycocorax differs notably from S. papuana by the long apical process of the median lobe, the long and sinuate parameres and the shape of the flagellum.
