description: Scaphisoma animatum sp. nov.
Figs 80-81
Holotype: SMNS; ♂; Indonesia, Lombok Is. Sapit- Sembalun Bumbung 14.-16.Feb.1994 Bolm lgt. 900- 1500 m.
Paratypes: SMNS, MHNG; 1 ♂, 2 ♀; with the same data as the holotype.
Etymology: The species epithet is a Latin adjective, meaning courageous.
Description: Length 1.37-1.46 mm, width 0.94- 0.96 mm. Head and most of body dark brown or reddish-brown. Most of elytra light, yellowish, basal fourth of elytra about as pronotum or somewhat darker, anterior halves of sutural areas slightly darkened, and each elytron with darkened subapical band. Ventral side of thorax about as dark as pronotum. Apical abdominal segments and appendages light, yellowish. Pronotum and elytra lacking microsculpture. Antennae long, length/width ratio of antennomeres as follows: III 12/7: IV 20/5: V 33/6: VI 40/8: VII 49/13: VIII 40/10: IX 48/12: X 45/11: XI 54/14. Antennomere III short, subtriangular. Pronotum very finely punctate, lateral margins evenly rounded, lateral margin carinae not visible in dorsal view. Point of scutellum exposed. Elytra with lateral margin carinae visible in dorsal view, apical margins weakly convex, inner apical angle rounded, not prominent, situated posterior level of outer angles, sutural margin not raised, sutural striae fairly shallow, parallel, somewhat curved at base, not extending laterad pronotal lobe, adsutural areas flat. Elytral punctation very fine and sparse, similar to pronotal near bases, more distinct on most of discal surface and with puncture intervals about 2 to 3 times as large as puncture diameters. Hypomera smooth. Mesepimeron slightly longer than interval to mesocoxa. Metaventrite not microsculptured, lacking mesal impressions or sulci, very finely punctate. Submesocoxal areas 0.04 mm, as long as third of interval to metacoxa, submesocoxal lines convex, with fine marginal punctures. Metanepisternum flat, slightly narrowed toward angles, with middle part of inner margin oblique, not impressed below margin of metaventrite. Tibiae straight. Abdomen very finely punctate, sternite 1 lacking microsculpture, apical sternites with punctate microsculpture. Submetacoxal areas 0.07-0.09 mm, almost reaching sternal mid-length, submetacoxal lines convex, with coarse margin punctures.
Male: Protarsal segments 1 to 3 hardly widened. Aedeagus (Figs 80-81) 0.25 mm long, moderately sclerotized. Median lobe symmetrical, with large basal bulb, articular process robust and prominent, apical process much shorter than basal bulb, strongly curved, tapering apically, tip acute in lateral view, blunt in dorsal view. Parameres symmetrical, narrow, almost straight in dorsal view, hardly bent and widened at apices in lateral view. Internal sac lacking flagellum and sclerotized pieces, membranes with fine denticulate structures.
Distribution: Indonesia: Lombok.
Type locality: Lombok, Sapit-Sembalun Bumbung, 900-1500 m.
Comments: The aedeagal characters suggest relationship with S. lombokense Löbl, 1986 and S. bugi Löbl, 1983, although these two species have parameres widened basally, and may be easily distinguished by their colour pattern and abdominal microsculpture (abdomen with striate microsculpture, body uniformly reddish-brown in S. lombokense, elytra dark with lighter reddish subbasal and subapical spots in S. bugi; see Löbl, 1983 and 1986, respectively).
