description: Anthelephila selamatra sp. nov.
(Figs 34–39)
Type locality. Indonesia, Sumatra, Lampung Province, Bukit Barisan Selatan National Park, 5 km SW of Liwa, 5°04′S 104°04′E, altitude ca 600 m.
Type material. HOLOTYPE: ♂, ‘ S SUMATRA, Lampung prov., BUKIT BARISAN SELATAN N.P., 5°4′S 104°4′E, ca 600 m, 5 km SW Liwa, J. Bezděk lgt., 7-17.ii.2000 [p]’ (NMPC). PARATYPES: 2♂♂ 2♀♀, same data as holotype (ZKDC); 1♂, ‘ E SUMATRA, RIAU prov. BUKIT TIGAPULUH N.P. 0°50′S 102°26′E, 18.-25.i.2000, D. Hauck lgt. [p]’ (ZKDC).
Description. Male (holotype). Body length 4.2 mm. Head largely black, with slight reddish-brown tinge anteriorly; pronotum and elytra black, unicolorous; femora brownish- black, tibiae and tarsi black; antennae black in terminal half/third, basal antennomeres with brownish tinge.
Head 1.2 times as long as wide, somewhat produced postero-medially (widely parabolic) and 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 2.2 times, X 2.1 times, XI 3.1 times as long as wide.
Pronotum 1.5 times as long as wide, distinctly narrower than head including eyes, nearly evenly rounded anteriorly, narrowed and rather sharply impressed (constricted) postero-laterally in dorsal view; pronotal disc evenly shaped, strongly 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 wrinkled. Setation as on head.
Mesoventrite with very slight indication of moderately wide median longitudinal bulge (no median carina); metaventrite moderately impressed medially, with indication of submedian setose patches.
Elytra rather short, 1.5 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, nearly decumbent, especially in basal third; scattered longer tactile setae.
Metathoracic wings developed.
Fore legs partly modified (Fig. 34); profemora simple; protibiae with small tooth-like protrusion on inner side, close behind mid-length; 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. 35) moderately emarginate and sinuous posteriorly. Sternite VIII (Figs 36, 37); paired prongs simple, evenly narrowing distally in lateral view. Tergum VII rather convex and distinctly produced posteriorly, rounded apically. Tergite VIII forming a pair of sclerites, narrowly connected postero-medially, subtruncate, with moderately produced, rounded lateral apical angle. Apical sclerite of segment IX membranous, widely narrowly rounded apically. Aedeagus (Figs 38, 39); apical portion of tegmen 0.5 times as long as basal-piece, trilobed apically.
Female. Externally differing from male as follows: fore legs quite simple; metaventrite simple, evenly sparsely punctate; abdominal sternum VII slightly produced and rounded apically; tergum VII subtriangular, rounded apically.
Variation. Body length (♂ ♀) 4.1–4.7 mm; head largely dark reddish-brown to entirely black.
Differential diagnosis. Anthelephila selamatra sp. nov. is externally similar to A. bogorensis (Pic, 1913), A. gibbithorax (Pic, 1901), A. modiglianii (Pic, 1901) and A. sunda sp. nov., that are all distributed on Sumatra, Java or Mentawai Islands. Externally, it may resemble especially A. gibbithorax from Mentawai in largely black colouration and morphology of pronotum (pronotal disc evenly convex, its outline somewhat bulging posteriorly in lateral view, laterobasal impression deepened dorso-laterally), but differs in shallowly emarginate male sternum VII (deeply excavate in A. gibbithorax), and straight and simple prongs of male sternite VIII (quite dissimilar, strongly curved in A. gibbithorax). Furthermore, the two discussed species share trilobed apex of tegmen (nearly identical), but the sclerotized inner structure of median lobe appears to be different.
Etymology. Composed from an Indonesian word Selatan (= south) and Sumatra; named in reference to the species distribution; noun in apposition.
Distribution. Indonesia (Sumatra).
