Anthelephila bolavensis sp. nov.

Figs 42–45

Description. Male (holotype). Body length 4.2 mm. Head and pronotum brownish, at places with reddish tinge; elytra dark brown, with slight greenish reflection; legs and antennae reddish, tibiae slightly darker basally.

Head 1.1 times as long as wide, its base moderately produced medially, differentiated from short neck; tempora strongly narrowing posteriad, posterior angles absent. Eyes medium-sized, rather convex. Dorsal surface only moderately glossy, distinctly punctate and largely corrugated; punctures distinctly separated. Setation short, subdecumbent; few erect setae. Antennae moderately enlarged in terminal third; antennomere X 1.5 times, XI 2.3 times as long as wide.

Pronotum 1.4 times as long as wide, moderately narrower than head including eyes, nearly evenly rounded anteriorly, strongly narrowed and moderately impressed (constricted) postero-laterally in dorsal view; pronotal disc evenly convex in lateral view. Surface glossy; antero-lateral sides minutely and sparsely punctate, nearly impunctate near procoxal cavities; disc more distinctly and densely punctate to corrugate, especially posteriorly, with some transverse wrinkles before smooth antebasal area; postero-lateral impressions longitudinally wrinkled, adjacent dorso-lateral surface rugose. Setation as on head.

Mesosternum nearly simple, with slight indication of median longitudinal bulge. Metasternum simple.

Elytra 1.7 times as long as wide, conjointly rounded apically; humeri distinct; postscutellar impression absent. Surface glossy, distinctly punctate; punctation double, setiferous punctures rather widely separated. Setation nearly evenly developed, sparser near base, generally longer and more raised than on head, decumbent; numerous tactile setae.

Metathoracic wings fully developed.

Fore legs modified (Fig. 42); profemora with short tooth-like process, rounded apically, with short fringe of stiff setae subapically; protibiae nearly simple, moderately swollen, with slight angulation on inner side in distal half; penultimate tarsomere widened/flattened distally, with terminal tarsomere articulated dorsally near base in all tarsi. Setation normally developed; tibiae with two equal terminal spurs.

Abdominal sternum III with conspicuous, paired submedian carinae, and rather distinctly impressed medially (between carinae). Sternum VII shallowly emarginate and rather scantily setose (Fig. 43). Tergum VII simple, widely rounded posteriorly. Sternite VIII (Fig. 44); paired prongs with prominent, flattened and triangular apex. Tergite VIII with simple paired sclerites rounded apically, narrowly connected medially. Terminal sclerite of segment IX (spiculum) membranous and inconspicuous. Aedeagus (Fig. 45); apical portion of tegmen 0.5 times as long as basal-piece, trilobed apically.

Female. Externally differing from male as follows: fore legs and abdominal sterna III, VII simple; tergum VII subtriangular, moderately produced and narrowly rounded apically.

Variation. Body length (♂ ♀) 3.4–4.2 mm. Head and pronotum reddish to dark brown, legs pale reddish to reddish-brown.

Type material. Holotype, ♂: LAOS south, Champasak prov., Bolaven Plateau, 10–18.IV.1999, Route (No. 23) Pakse—Paksong, BAN ITOU env. (km 35), alt. 800m, N 15°10.4′ E 106°05.8′ (GPS), M. Štrba leg. [p] (NMPC).

Paratypes: 3 ♂♂, same data as holotype (ZKDC); 9 ♂♂, same data, except: E. Jendek & O. Šauša leg. (ZKDC, DCDC).

Additional specimens. Laos: 4 ♀♀, same data as holotype (ZKDC); 9 ♀♀, same data as holotype, except: E. Jendek & O. Šauša leg. (ZKDC, NMPC).

Differential diagnosis. Anthelephila bolavensis sp. nov. belongs to the A. fossicollis species-group. It can be recognized by the shallowly and rather widely emarginate male sternum VII, which is only sparsely setose medially, and by the triangular flattened apex of the paired prongs.

Etymology. Named after the type locality (Bolaven Plateau).

Distribution. Laos.
