description: Anthelephila utara sp. nov.
(Figs 45–50)
Type locality. Indonesia, Sumatra, North Sumatra Province, Pematang Siantar 20 km direction Prapat, altitude ca. 1000 m.
Type material. HOLOTYPE: ♂, ‘ N - Sumatra P - Siantar 20 km Richtung Prapat [h] // ca 1000 m Lichtfang April-September 1986 leg. Dr. Diehl [h] // Formicomus bataviensis Pic det. G. Uhmann 1987 [p]’ (ZSMC). PARATYPES: 1♂ 1♀, ‘ Gunung Singgalang (Sumatra’s Westkust) 1600 M. VII 1925 leg. E. Jacobson. [p+h]’ (ZKDC).
Description. Male (holotype). Body length 4.0 mm. Black, nearly unicolorous, legs partly with brownish tinge, antennae brownish-black, basal antennomeres paler.
Head 1.2 times as long as wide, somewhat angled postero-medially (widely parabolic), distinctly differentiated from short neck; tempora strongly narrowing posteriad, posterior angles absent. Eyes medium-sized, rather convex. Dorsal surface glossy, distinctly punctate; punctures largely umbiliform, more delicate basally, distinctly separated. Setation subdecumbent; scattered longer tactile setae.Antennae only moderately enlarged in terminal third; antennomere I 1.9 times, X 1.7 times, XI 3.7 times as long as wide.
Pronotum 1.5 times as long as wide, distinctly narrower than head including eyes, nearly evenly rounded anteriorly, strongly narrowed and impressed (constricted) postero-laterally in dorsal view; pronotal disc somewhat flattened medially, nearly evenly moderately convex in lateral view. Surface smooth and glossy; disc punctate, similarly as head, with some transverse wrinkles in front of smooth antebasal area; lateral sides largely impunctate, postero-lateral impressions wrinkled and adjacent dorso- lateral surface rugose. Setation as on head.
Mesoventrite with simple, moderately wide, median longitudinal bulge, at most slightly convex in lateral view, with short setae scattered along margins, and a few long, coarse setae postero-medially; metaventrite simple.
Elytra 1.7 times as long as wide, conjointly rounded apically; humeri distinct, postscutellar impression at most slightly indicated. Surface glossy, distinctly punctate; punctation double, rather evenly developed, setiferous punctures widely separated. Setation uniform, distinctly longer and more raised than on head, nearly decumbent; numerous erect tactile setae.
Metathoracic wings developed.
Fore legs modified (Figs 45, 46); profemoral process tooth-like, short and bluntly pointed; protibiae with longitudinal carina, abruptly ending distally with minute denticle; 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. 47) distinctly sinuous postero-medially. Sternite VIII (Figs 48, 49); paired prongs elongate, slender, with conspicuously long and coarse setae laterally in basal half and tufted, longer setae subapically. Tergum VII narrowly rounded apically. Tergite VIII forming a pair of sclerites, narrowly connected medially, narrowly rounded apically. Apical sclerite of segment IX inconspicuous. Aedeagus (Fig. 50); apical portion of tegmen 0.2 times as long as basal-piece, wide and bilobed apically.
Female. Externally differing from male as follows: fore legs simple; abdominal sternum VII simple, very slightly produced and rounded to subtruncate apically; tergum VII subtriangular, rounded apically.
Variation. Body length (♂ ♀) 4.0– 4.3 mm.
Differential diagnosis. Anthelephila utara sp. nov. is close to A. antennalis sp. nov., but differs in many details of male characters, e.g. less elongate terminal antennomere, robust profemoral process, slight protrusion of metatibiae (situated rather distally), nearly sinuous posterior margin of sternum VII, paired prongs bearing conspicuous subapical tuft of long setae, and in shorter apical lobes of tegmen.
Etymology. The species name utara is the Malay word for north, and should be treated as noun in apposition; named in reference to the location of type locality in the North Sumatra province (‘ Sumatera Utara’).
Distribution. Indonesia (Sumatra).
