Figs 71–75 View FIGURES 71 – 75 , 110 View FIGURES 107 – 114

Description. Body length 6.2 mm. Body reddish; legs and antennae reddish, tibiae somewhat darkened at base.

Head about 1.2 times as long as wide, nearly smoothly merging with long, longitudinally corrugated neck; tempora strongly narrowing posteriad, posterior angles absent. Eyes large and strongly convex. Dorsal surface moderately glossy, distinctly punctate and largely corrugated, especially medially to eyes; punctures distinctly separated. Setation subdecumbent; several conspicuously long, tactile setae. Antennae extremely long and slender, including terminal third; antennomere X 3.2 times as long as wide.

Pronotum 1.6 times as long as wide, distinctly narrower than head including eyes, nearly evenly rounded anteriorly, strongly narrowed and moderately impressed (constricted) postero-laterally in dorsal view; pronotal disc nearly evenly convex in lateral view. Surface largely glossy; antero-lateral sides sparsely punctate to impunctate near procoxal cavities; disc densely punctate, with slight indication median groove posteriorly, and conspicuously transversely corrugated before base; postero-lateral impressions coarsely, longitudinally wrinkled. Setation as on head.

Mesosternum with distinct median longidudinal bulge, its outline straight in lateral view. Metasternum simple.

Elytra 1.5 times as long as wide, ovoid and strongly convex, conjointly rounded apically; humeri distinct; postscutellar impression absent. Surface glossy, distinctly punctate; punctation double, setiferous coarse punctures rather widely separated. Setation nearly evenly developed, sparser in basal third/fourth, generally longer and more raised than on head, decumbent; numerous long, tactile setae.

Metathoracic wings fully developed.

Fore legs modified ( Fig. 71 View FIGURES 71 – 75 ); profemora with small, slender, sharply pointed process; protibiae with small, tooth-like protrusion on inner side at about mid-length; penultimate tarsomere widened/flattened distally, with terminal tarsomere articulated dorsally near base in all tarsi. Setation normally developed, distinctly longer and more raised on metatibiae; tibiae with two equal terminal spurs.

Abdominal sternum VII ( Fig. 72 View FIGURES 71 – 75 ) moderately emarginate posteriorly, with conspicuous median process projecting from dorsal (inner) side. Tergum VII simple, widely rounded posteriorly. Sternite VIII ( Figs 73, 74 View FIGURES 71 – 75 ); paired prongs bilobed. Tergite VIII with paired sclerites narrowly connected medially, simply rounded apically. Aedeagus ( Fig. 75 View FIGURES 71 – 75 ); apical portion of tegmen 0.6 times as long as basal-piece, trilobed apically.

Type material. Holotype, ♂ [lacking both terminal antennomeres]: LAOS centr., Khammouan pr., BAN KHOUN NGEUN vill. env., 17.v.–, ~ 300m, M. Štrba leg. [p] ( NMPC).  

Differential diagnosis. Anthelephila keahi   sp. nov. appears to be close to A. mirabilis (Telnov, 1997)   from northern Vietnam, as suggested by its larger size, reddish body colouration, head smoothly merging with long neck, and long, slender antennae. It differs clearly in all male characters, especially by the shape of the median process of sternum VII and the paired prongs.

Etymology. Species name is Laotian girl name Keahi (flames, fire), refering to uniformly reddish colouration. Noun in apposition.

Distribution. Laos.
