PARATYPES: 1 ♀, same data as holotype ( ZKDC) ; 1 J, ‘NE INDIA, Arunachal Pradesh, DIRANG vicinity, 1800± 100m, 27°21′N, 92°13′E, Pacholátko leg., 8.–22.v.2006 ’ ( ZKDC) ; 1 J 4 ♀♀, ‘NE INDIA, Arunachal Pradesh, RUPA vicinity, 1600± 100 m 27°11–12′N, 92°24′E, 20.–22.vi.2004, R. Businský leg.’ ( ZKDC) .

Description (male, holotype). Body length 5.9 mm. Head brown black, its base paler, neck dark reddish brown; pronotum dark reddish; elytra black with slight bluish reflection, slightly reddish at base; legs brown black to black, tarsi paler, antennae dark reddish, slightly darkened apically.

Head produced postero-medially and nearly fluently passing into longer neck; tempora strongly narrowing posteriad, posterior angles absent. Eyes medium-sized and rather convex. Dorsal surface glossy, finely and sparsely punctate; punctation in anterior half somewhat more distinct, umbiliform. Setation mostly subdecumbent, with some longer and erect bristly setae. Antennae conspicuously long, slightly enlarged in terminal third; antennomeres IV–VI about 3.0 times, antennomere X 2.5 times and antennomere XI 3.0 times as long as wide.

Pronotum 1.6 times as long as wide, distinctly narrower than head across eyes, nearly evenly rounded anteriorly, narrowed and distinctly impressed postero-laterally (constricted) in dorsal view; pronotal disc with moderate median longitudinal impression, its outline convex in anterior half and flattened to slightly impressed posteriorly in lateral view. Dorsal surface smooth, distinctly punctate, with some coarse transverse wrinkles before base; antero-lateral sides finely, sparsely punctate, impunctate near procoxal cavities; postero-lateral impression coarsely wrinkled and adjacent, basal area somewhat rugose (densely punctate); dorsal median punctation similar to that on head, rather fine and sparse. Setation as on head.

Mesosternum simple; metasternum with a pair of setose protuberances posteriorly, shortly before median margin of metacoxae.

Elytra 1.9 times as long as wide, conjointly rounded apically; humeri distinct; postscutellar impression absent. Surface glossy, distinctly punctate; punctation simple, rather sparse. Setation similar to that on head, generally more raised, evenly developed.

Metathoracic wings fully developed.

Fore legs modified ( Fig. 72 ); profemora with long and narrow, moderately sinuous process with rounded apex, bearing a cluster of short, stiff setae subapically; protibiae impressed and moderately lobed on inner side distally, surface of impression smooth and glossy, asetose; penultimate tarsomere widened and flattened distally, with terminal tarsomere articulated dorsally in all tarsi. Setation of tibiae generally rather long and raised.

Abdominal characters as in Figs. 73–76 ; sternum VII rather deeply impressed to excavated medio-basally; median process of sternum VII dorso-ventrally flattened, its apex trilobate and middle lobe tridentate; tergum VII simple, nearly evenly rounded apically; paired prongs of sternite VIII dorso-ventrally flattened, with conspicuous simple process/lobe ventrally in apical third; apical portion of tegmen 0.4 times as long as basal piece, with a pair of finely membranous apical projections/lobes.

Female. Externally differing from male by simple metasternum and fore legs, abdominal sternum VII moderately produced and rounded apically, and tergum VII subtriangular, simply rounded apically.

Variation. Body length (J ♀) 4.9–6.0 mm.

Differential diagnosis. Anthelephila triungula sp. nov. belongs to the A. lagenicollis species-group ( KEJVAL 2000). It is undoubtedly related to A. psiloptera in having a conspicuous, apically setose profemoral process, long median process of male sternum VII, simple apex of tegmen and similar general form of male sternite VIII. It can be distinguished from the latter species by the longer and much narrower male profemoral process, apically trilobed median process of male sternum VII (quite dissimilar and simple in A. psiloptera ), as well as by many details in the morphology and setation of male sternite VIII.

Etymology. Composed from the Latin words tri (three) and ungula (claw, talon) in reference to the peculiar morphology of the median process of male sternum VII. Noun in apposition.

Distribution. India (Arunachal Pradesh).
