Scaphobaeocera notata sp. n.

( Figs 13-15 )

Type material. Holotype ♂: PAPUA NG: Morobe Mt. Mission, Bitoi Rd 1350m, 22.V.1992 G. CUCCODORO # 6A [rotting trunk and vegetational debris in pine-oak plantation] ( MHNG).

Paratypes: 2 ♂♂, 2 ♀♀, 5 specimens sex not examined, same data as the holotype ( MHNG); 5 ♂♂, 1 ♀, 6 specimens sex not examined, same data but #6B [under rotting trunk, lower montane rain forest] ( MHNG); 1 ♀, NEW GUINEA /NE/ Wau , Mt. Missim 1200 m 20.VIII.1068 / No. NG-“-B.35 leg. Dr. J . BALOGH (HNMB).

Description. Length 0.96-1.20 mm, width 0.56-0 67 mm, dorsoventral diameter 0.57-0.65 mm. Head and body light reddish-brown. Elytra each with a dark spot centred anterior mid-length, and darkened in apical seventh or sixth. Appendages somewhat lighter than most of body. Length/width ratios of antennomeres as: III 13/5: IV 18/5: V 27/5: VI 25/6: VII 28/12: VIII 23/8: IX 31/12: X 32/12: XI 45/13 (Fig. 15). Pronotum very finely punctate, not microsculptured. Visible tip of scutellum minute. Elytra with parasutural striae, sutural striae shallow, somewhat curved near base, usually with distinct strigulate microsculpture, discal punctation almost as fine as pronotal punctation, sometimes weakly iridescent. Hypomera not microsculptured, appearing smooth, lacking longitudinal stria. Middle area of metaventrite flattened, without median stria or impression, with dense and rather coarse punctation surrounding smooth centre, some punctures larger than puncture intervals, pubescence short. Lateral parts of metaventrite very finely punctate, not microsculptured. Submesocoxal areas about 0.02 mm, submesocoxal lines punctate. Metanepisterna about 0.05-0.0 7 mm wide, flat, not narrowed anteriad, impunctate, with straight suture reaching metepimera. Tibiae straight. Sternite 1 without obvious microsculpture, not iridescent, very finely punctate, with rather coarse basal punctures; apical sternites with strigulate microsculpture.

Male: Protarsomeres 1 to 3 widened, narrower than apices of protibiae. Aedeagus as in Figs 13, 14, 0.25-0.29 mm long.

Etymology. The species epithet is a Latin adjective, meaning spotted.

Differential diagnosis. This species may be readily distinguished by the elytra, each bearing a dark spot. The aedeagal characters suggest relationships with S. nuda LÖBL, 1979 from India (see LÖBL 1984 ). These two species may be distinguished, in addition to the colour pattern, by the elytra lacking microsculpture and the strigulate microsculpture on apical abdominal segments S. nuda.
