Diagnosis. Body large, BL around 1.7 mm; antennae gradually thickened; punctures on clypeus virtually absent, on frontovertexal region moderately large, sharply marked and dense, those at middle separated by spaces subequal to their diameters, punctures near eyes slightly denser, punctures on median region of pronotal disc smaller than those on frontovertexal region but also sharply marked and similarly dense, those on elytra fine and inconspicuous; subhumeral lines short, as long as 0.25 × EL. Male: aedeagus ( Figs 195–197 View FIGURES 194–201 ) in ventral view with capsular region of median lobe with broadly rounded distal margin; subapical lateral lobes conspicuously large and semicircular; apical projection trilobate, with two lateral subtriangular lobes and also subtriangular and pointed apical lobe; subapical distal projection in dorsal view subrectangular, wider than long and with subtriangular and projecting distolateral corners, in lateral view apical lobe distally angulate, and subapical dorsal projection recurved; each paramere with four setae.

Description. Body of male ( Fig. 194 View FIGURES 194–201 ) strongly convex, oval, with barely discernible constriction between pronotum and elytra, moderately dark brown with slightly lighter tarsi, covered with light brown setae. BL 1.73 mm.

Head broadest across large and conspicuously strongly convex, coarsely faceted eyes, HL 0.25 mm, HW 0.40 mm; frontovertexal region weakly convex at middle; supraantennal tubercles weakly elevated. Punctures on clypeus virtually absent, on frontovertexal region moderately large, sharply marked and dense, those at middle separated by spaces subequal to their diameters, punctures near eyes slightly denser; setae short, sparse and suberect. Antennae long and slender, gradually thickened, AnL 0.88 mm, antennomere 1 about as long as broad, 2 distinctly elongate, 3–6 each weakly transverse, 7–10 each about as long as broad, 11 nearly as long as 9 and 10 combined, about 1.7 × as long as broad.

Pronotum semi-oval, strongly convex at middle and flattened near anterior and hind corners, broadest near middle and weakly narrowing posterad; PL 0.53 mm, PW 0.78 mm. Anterior margin in strictly dorsal view nearly straight; lateral margins strongly rounded in anterior third and weakly sinuate posteriorly, just in front of hind corners weakly concave, finely microserrate, posterior corners nearly right-angled; posterior margin shallowly bisinuate; lateral marginal carinae simple (i.e., not doubled); lateral antebasal pits shallow but distinct, each located slightly closer to posterior than to lateral pronotal margin. Punctures on median region of pronotal disc slightly smaller than those on head but also sharply marked and separated by spaces subequal to their diameters, punctures near anterior and posterior corners denser and somewhat coarse; setae short and moderately dense, suberect.

Elytra slightly wider than pronotum, together oval, broadest near anterior third; EL 0.95 mm, EW 0.83 mm, EI 1.15; subhumeral lines developed as sharp borders between elevated humerus and lower mesal region, as long as 0.25 × EL and weakly divergent posterad; basal elytral fovea on each elytron slightly closer to lateral margin of mesoscutellum than to subhumeral line; elytral apices separately rounded.Punctures on elytra fine and inconspicuous; setae similar to those on pronotum.

Hind wings lacking.

Metaventrite with deep lateral impressions as long as 4/5 of its length.

Legs long and slender, unmodified.

Aedeagus ( Figs 195–197 View FIGURES 194–201 ) AeL 0.58 mm; in ventral view capsular region of median lobe with broadly rounded distal margin; subapical lateral lobes conspicuously large and semicircular; apical projection trilobate, with two lateral subtriangular sharp-angled lobes and also subtriangular and pointed apical lobe; in lateral view apical lobe distally angulate; subapical dorsal projection in ventral view subrectangular, wider than long and with subtriangular and projecting distolateral corners, in lateral view subapical dorsal projection sinuate; each parameral apex strongly curved mesad and with four setae.

Female. Unknown.

Distribution. S China: Yunnan.

Etymology. The adjective pingbianus refers to the type locality in Pingbian Miao Autonomous County.

Remarks. Cephennodes pingbianus can be identified by its unique aedeagus, which in ventral view has a trilobate apical structure, composed of a pair of subtriangular sharp-angled lateral lobes and also a triangular apical lobe.
