Cephennodes (Cephennodes) pseudogokarnaensis sp. n.

( Figs 233, 235–236 , 245 )

Type material. Holotype: NEPAL ( Sankhuwasabha District ): ♂, one label: "E. NEPAL: KOSI / Val . Induwa Kola / 2000 m, 16.IV.84 / Löbl - Smetana" [white, printed] (MHNG). Paratype: 1 ♂, "E. NEPAL: KOSI / Forêt S. Mangsingma / 2250 m, 12.IV.84 / Löbl - Smetana" [white, printed] ( MHNG) .

Diagnosis. BL 1.23–1.25 mm; species of the C. gokarnaensis group with apex of median lobe of aedeagus subtriangular; apical projection of aedeagus directed toward apex of median lobe.

Description. Body of male ( Fig. 232 ) dark brown, moderately stout, with moderately deep constriction between pronotum and elytra, strongly convex, covered with light brown setae; BL 1.23–1.25 mm.

Head subtrapezoidal, HL 0.18 mm, HW 0.30 mm; vertex and frons confluent and weakly, evenly convex, supraantennal tubercles small, weakly elevated; eyes moderately large, strongly convex, coarsely faceted. Punctures on vertex and frons very small but distinct, sharply marked, slightly sparser on median area than on sides, separated by spaces subequal to diameters of punctures; setae sparse, short, suberect. Antennae moderately long and moderately strongly thickened, AnL 0.65 mm, pentamerous club indistinctly delimited; antennomere I about 1.2 × as long as broad; II narrower than I but similar in length, 1.3 × as long as broad; III slightly narrower and much shorter than II, about as long as broad, IV–VI each as broad as III but indistinctly longer, 1.1 × as long as broad, VII slightly broader and distinctly longer than VI, about 1.4 × as long as broad; VIII distinctly broader and shorter than VII, about as long as broad; IX and X each distinctly larger than preceding ones, each about as long as broad; XI slightly broader than X, slightly shorter than IX–X together, about 1.6 × as long as broad.

Pronotum in dorsal view subrectangular with rounded sides, broadest near middle, PL 0.38 mm, PW 0.55 mm; anterior margin in strictly dorsal view slightly arcuate; lateral margins indistinctly microserrate, strongly rounded in anterior third, distinctly less so in posterior half and weakly convergent toward obtuse-angled hind corners; posterior margin shallowly bisinuate; lateral carinae distinct but narrow, fused with lateral margins; antebasal pits small and shallow, nearly equally distant from posterior and lateral pronotal margins. Punctures on disc slightly larger than those on frons and vertex, sharply marked, those in median area separated by spaces slightly shorter than diameters of punctures; setae moderately long, dense, suberect.

Elytra elongate, oval, broadest slightly in front of middle, EL 0.68–0.70 mm, EW 0.60–0.63 mm, EI 1.12– 1.13. Humeral calli weakly elevated; subhumeral lines very narrow, divergent posteriorly, equal to about 0.4 EL, each developed as moderately sharp stepwise border between more convex humeral region and less convex adsutural area; basal pit on each elytron located in shallow and round basal impression; apices of elytra separately rounded. Punctures slightly larger and slightly sparser than those on pronotum, relatively sharply marked, distinct; setae similar to those on pronotum, except for subapical region, where setae are distinctly denser and directed posteromesally.

Hind wings not studied.

Metaventrite with large, sharply delimited postmesocoxal impressions, with median area covered with fine, dense punctures.

Abdomen and legs unmodified.

Aedeagus ( Figs 235–236 ) stout, AeL 0.13 mm, apex of median lobe subtriangular; apical projection broad, directed slightly toward apex of median lobe, rounded; parameres very slender, strongly unequal in length, one not reaching and one exceeding apex of median lobe, each with one long apical seta.

Female. Unknown.

Distribution ( Fig. 245 ). Eastern Nepal.

Etymology. The name pseudogokarnaensis was chosen to emphasize similarity to C. gokarnaensis .

Remarks. See remarks for C. gokarnaensis .
