description: Anthelephila pectinipes sp. nov.
(Figs 23–28)
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: 10 ♂♂ 4 ♀♀, same data as holotype (ZKDC, DCDC).
Description. Male (holotype). Body length 4.8 mm. Body black, unicolorous, with slight greenish reflection; 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), weakly differentiated from short neck; tempora strongly narrowing posteriad, posterior angles absent. Eyes medium-sized, rather convex. Dorsal surface glossy, delicately punctate; punctures widely separated. Setation subdecumbent; scattered longer tactile setae.Antennae at most slightly enlarged in terminal third; antennomere I 2.5 times, X 1.9 times, XI 3.1 times as long as wide.
Pronotum elongate, 1.6 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 narrow median longitudinal bulge, largely forming coarse, setose median carina; metaventrite simple.
Elytra 1.6 times as long as wide, conjointly rounded apically; humeri distinct, postscutellar impression absent. Surface glossy, sparsely, rather evenly punctate; punctation double, setiferous 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 modified (Fig. 23); profemora with slight protrusion and dense fringe of short, spine-like setae along inner carinate margin in basal half; protibiae with small denticle close behind mid-length, flattly impressed and with carinate lateral margin 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. 24) rather narrow, moderately produced and emarginate postero-medially. Sternite VIII (Fig. 25); paired prongs simple, long and slender, moderately bent, widened apically. Tergum VII rather convex and distinctly produced posteriorly, rounded apically. Tergite VIII forming a pair of sclerites, narrowly connected postero-medially, rounded apically (Fig. 26). Apical sclerite of segment IX inconspicuous, weakly sclerotized, rounded apically. Aedeagus (Fig. 27); apical portion of tegmen 0.7 times as long as basal-piece, trilobed apically, middle lobe wider and with apical notch.
Female. Externally differing from male as follows: fore legs simple; mesoventrite nearly simple, with slight indication of median carina posteriorly and several setae in median line; abdominal sternum VII conspicuously modified (Fig. 28); tergum VII subtriangular, narrowly rounded apically.
Variation. Body length (♂ ♀) 4.0– 4.8 mm.
Differential diagnosis. Anthelephila pectinipes sp. nov. is undoubtedly close to A. bukaba sp. nov., as suggested by similarity of external (e.g. slender pronotum, evenly shaped pronotal disc) and numerous male characters, including morphology of tegmen (Figs 27, 14). It differs from the latter species in modified male profemora (slight protrusion and carinate inner margin), bearing coarse spine-like setae, in rather slightly emarginate male sternum VII and apically widened and flattened prongs of male sternite VIII. Females can be easily distinguished by simple, conjointly rounded elytra apices (conspicuously produced and pointed in A. bukaba sp. nov.) and peculiar modification of sternum VII.
Etymology. Composed from Latin pecten (comb, brush) and pes (foot); named in reference to peculiar dense fringe of spine-like setae on inner proximal margin of male profemora; noun in apposition.
Distribution. Indonesia (Sumatra).
