description: Anthelephila bukaba sp. nov.
(Figs 9–14, 51, 52)
Type locality. Indonesia, Sumatra, Bengkulu Province, near Curup, Bukit Kaba Mount, 3°29′S 102°36′E, altitude 1000–1500 m.
Type material. HOLOTYPE: ♂, ‘ W SUMATRA, Bengkulu prov., nr.Curup, BUKIT KABA Mt., 3°29′S 102°36′E, 1000-1500 m, J. Bezděk lgt., 30.i.- 3.ii.2000 [p]’ (NMPC). PARATYPES: 12 ♂♂ 18 ♀♀, same data as holotype (ZKDC, NMPC, DCDC).
Description. Male (holotype). Body length 4.6 mm. Body black, unicolorous (Fig. 51); antennae and legs brownish-black, basal antennomere brownish, narrowed basal portion of femora reddish-brown.
Head 1.2 times as long as wide, somewhat angled postero-medially (widely parabolic), differentiated from short neck; tempora strongly narrowing posteriad, posterior angles absent. Eyes medium-sized, rather convex. Dorsal surface glossy, delicately punctate, wrinkled anteriorly on frons; punctures widely separated. Setation subdecumbent; scattered longer tactile setae. Antennae moderately enlarged in terminal third; antennomere I 2.7 times, X 1.9 times, XI 2.9 times as long as wide.
Pronotum elongate, 1.7 times as long as wide, distinctly narrower than head including eyes, nearly evenly rounded anteriorly, weakly narrowed and impressed (constricted) postero-laterally in dorsal view; pronotal disc evenly shaped, nearly evenly moderately convex in lateral view. Surface smooth and glossy, including posterior third; disc sparsely punctate, similarly as head; lateral sides largely impunctate, postero-lateral impressions coarsely shortly wrinkled. Setation as on head.
Mesoventrite with inconspicuous, narrow median longitudinal bulge, somewhat uneven in lateral view, rounded anteriorly, otherwise forming coarse median carina, with several longer setae antero-laterally and in median line posteriorly; metaventrite simple, with slight indication of paired longitudinal, submedian patches of dense, coarser punctures.
Elytra 1.7 times as long as wide, conjointly rounded apically; humeri distinct, postscutellar impression absent. Surface glossy, sparsely, rather evenly punctate; punctures delicate, widely separated. Setation uniform, distinctly longer than on head, nearly decumbent, especially in basal third; scattered tactile setae.
Metathoracic wings developed.
Fore legs partly modified (Fig. 9); profemora simple; protibiae impressed and with angled lobule on inner side distally; all tibiae with two terminal spurs; penultimate tarsomere widened/flattened distally, with terminal tarsomere articulated dorsally near base for all tarsi.
Abdominal sternum VII (Fig. 10) deeply emarginate, with narrowly produced lateral lobes, rather scantily setose. Sternite VIII (Fig. 11); paired prongs simple, long and slender, moderately bent. Tergum VII rather convex and strongly produced posteriorly, narrowly rounded apically (Fig. 12). Tergite VIII forming a pair of sclerites, rather widely connected postero-medially, narrowly produced (Fig. 13). Apical sclerite of segment IX inconspicuous, weakly sclerotized, rounded apically. Aedeagus (Fig. 14); apical portion of tegmen 0.7 times as long as basal-piece, trilobed apically, middle lobe wider and with deep apical notch.
Female. Externally differing from male as follows: elytral apices conspicuously narrowly produced (Fig. 52); fore legs simple; metaventrite evenly sparsely punctate; abdominal sternum VII conspicuously, abruptly produced and slightly emarginate apically; tergum VII subtriangular, produced and narrowly rounded apically.
Variation. Body length (♂ ♀) 4.0– 5.2 mm.
Differential diagnosis. Anthelephila bukaba sp. nov. is undoubtedly close to A. pectinipes sp. nov., as suggested by similarity of external (e.g. slender pronotum, evenly shaped pronotal disc) and numerous male characters, including morphology of tegmen apex (Figs 14, 27). It can be easily distinguished from the latter species by quite simple and delicately setose male profemora, deeply emarginate male sternum VII and apically slender prongs of male sternite VIII. Females are very conspicuous in having extremely produced and pointed elytral apices (simple, shaped similarly in both sexes in A. pectinipes sp. nov.).
Etymology. Named after the type locality (Bukit Kaba Mount); noun in apposition.
Distribution. Indonesia (Sumatra).
