Description. Male (holotype). Body length 3.0 mm. Head, pronotum, elytra and legs brown, at places with reddish tinge; antennae largely reddish, distinctly darkened, brownish in terminal third.

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, moderately convex. Dorsal surface glossy, distinctly unevenly punctate; punctures coarser, umbiliform anteriorly, delicate and sparser basally, distinctly separated. Setation short, subdecumbent; scattered longer tactile setae. Antennae moderately enlarged in terminal third; antennomere I 1.9 times, X 1.25 times, XI 2.0 times as long as wide.

Pronotum 1.4 times as long as wide, much narrower than head including eyes, nearly evenly rounded anteriorly, narrowed and strongly impressed (constricted) postero-laterally in dorsal view; pronotal disc convex anteriorly, distinctly impressed posteriorly and flattened in front of base in lateral view, anterior convex part with distinct median longitudinal impression/groove. Surface rather glossy; antero-lateral sides minutely and sparsely punctate, impunctate near procoxal cavities; disc with some coarser punctures, distinctly corrugated at constriction, in front of smooth antebasal area; postero-lateral impressions distinctly longitudinally wrinkled, adjacent dorso-lateral surface rugose. Setation as on head.

Mesoventrite simple. Metaventrite with slight indication of paired setose submedian projections close to posterior margin.

Elytra 1.6 times as long as wide, conjointly rounded apically; humeri and postscutellar impression distinct. Surface glossy, distinctly punctate; punctation uneven, double, setiferous punctures both rather widely separated and forming dense transverse band in postscutellar impression. Setation uneven, diversified, pale and whitish; ordinary pale setae somewhat longer and sparser in basal fourth, mostly subdecumbent; whitish setae short, subdecumbent, coarse, forming narrow transverse setose band in postscutellar impression; scattered, moderately longer tactile setae.

Metathoracic wings fully developed.

Fore legs modified ( Fig. 5 ); profemoral process robust, rounded to subtruncate apically, with short fringe of stiff setae subapically; protibiae with small lobule on inner side in distal third; pro- and mesotibiae with two, metatibiae with single distinct terminal spur; metatibiae with tuft of long stiff setae on median side subapically; penultimate tarsomere widened/flattened distally, with terminal tarsomere articulated dorsally near base for all tarsi.

Abdominal sternum VII with rounded median lobe, coarsely setose on margins ( Fig. 6 ). Tergum VII moderately produced and angled apically. Sternite VIII ( Fig. 7 ); paired prongs narrow and straight in lateral view. Tergite VIII with simple paired sclerites bluntly pointed apically, narrowly connected medially. Apical sclerite of segment IX thin and inconspicuous. Aedeagus ( Fig. 8 ); apical portion of tegmen 0.5 times as long as basal-piece, trilobed apically.

Female. Externally differing from male as follows: fore legs and metaventrite simple; abdominal sternum VII simple, slightly angled apically; tergum VII subtriangular, rounded apically.

Variation. Body length (♂ ♀) 2.7–3.2 mm.

Differential diagnosis. Anthelephila balijava sp. nov. belongs to the A. praetor species-group ( KEJVAL 1999). It is close to A. celer ( Laos, Thailand, Vietnam) and A. promiscua ( Philippines: Luzon), sharing narrower pronotum, well-developed median longitudinal impression of pronotal disc, apically narrower profemoral process and lobed median margin of male sternum VII. It can be easily confused with A. promiscua , considering similarity of male sternite VIII, but its paired prongs are markedly more slender, with evenly lobed dorsal margin, and prominent subapical denticle, situated very near apex; see Fig. 26 by KEJVAL (1999).

Etymology. Named after the Bali and Java islands; noun in apposition.

Distribution. Indonesia (Bali, Java).
