Anthelephila alamea   sp. nov. Figs 16–19 View FIGURES 16 – 19

Description. Male (holotype). Body length 4.5 mm. Head and pronotum dark reddish; elytra brownish black, with slight bluish reflection; legs and antennae reddish-brown, distal antennomeres somewhat darker.

Head 1.2 times as long as wide, differentiated from short neck; tempora strongly narrowing posteriad, posterior angles absent. Eyes medium-sized, rather convex. Dorsal surface moderately glossy, distinctly punctate and largely corrugated (especially medially to eyes), with indication of smooth, impunctate median strip posteriorly; punctures distinctly separated. Setation short, subdecumbent; few erect setae. Antennae moderately enlarged in terminal third; antennomere X 1.5 times, XI 2.2 times as long as wide.

Pronotum 1.4 times as long as wide, slightly narrower than head including eyes, nearly evenly rounded anteriorly, strongly narrowed and moderately impressed (constricted) postero-laterally in dorsal view; pronotal disc evenly convex. Surface rather glossy, mostly minutely and sparsely punctate, coarser postero-medially, nearly impunctate near procoxal cavities, with several transverse wrinkles dorsally shortly before base and smooth antebasal area; postero-lateral impressions and adjacent dorso-lateral area rather coarsely, longitudinally wrinkled. Setation as on head.

Mesosternum simple, with indication of median carina posteriorly, its outline slightly convex in lateral view. Metasternum simple.

Elytra 1.6 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. 16 View FIGURES 16 – 19 ); profemora with shorttooth-like process, rounded apically, with short fringe of stiff setae subapically; protibiae nearly simple, moderately swollen and with slight ridged protrusion on inner side; penultimate tarsomere widened/flattened distally, with terminal tarsomere articulated dorsally near base in all tarsi. Setation normally developed; pro- and mesotibiae with two, metatibiae with single distinct terminal spur.

Abdominal sternum III with paired submedian, longitudinal carinae at base; sternum VII ( Fig. 17 View FIGURES 16 – 19 ) moderately emarginate to incised posteriorly, and with minute, coarsely setose median process, projecting from its margin. Tergum VII simple. Sternite VIII ( Fig. 18 View FIGURES 16 – 19 ), paired prongs simple, apically pointed and coarsely setose. Tergite VIII with paired sclerites subtruncate apically, narrowly connected medially. Terminal sclerite of segment IX (spiculum) membranous, narrowed apically. Aedeagus ( Fig. 19 View FIGURES 16 – 19 ); apical portion of tegmen 0.4 times as long as basal-piece, trilobed apically.

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

Variation. Body length (♂♀) 4.4–4.5 mm.

Differential diagnosis. Anthelephila alamea   sp. nov. belongs to the A. fossicollis   species-group. It resembles A. keilana   sp. nov. in having comparatively simple, slender prongs of male sternum VIII, but differs in many details (cf. Figs 18 View FIGURES 16 – 19 versus 78).

Etymology. Species name is Laotian girl name, Alamea (precious), and should be treated as noun in apposition.

Distribution. Burma, Laos.
