Diagnosis. Body small, BL around 1.0– 1.2 mm; antennae gradually thickened; punctures on clypeus small but sharply marked, on frontovertexal region virtually lacking, on pronotum and elytra small but sharply marked and dense, separated by spaces subequal to their diameters, those on elytra slightly larger than on pronotum; subhumeral lines short, as long as 0.3 × EL. Male: aedeagus ( Figs 182–183 View FIGURES 181–184 ) in ventral view with capsular region of median lobe conspicuously small, as wide as long and truncate distally, in lateral view dorsal apical projection massive and curved ventrad, and dorsal apical projection also thick but straight, parameres of conspicuously uneven lengths.

Description. Body of male ( Fig. 181 View FIGURES 181–184 ) moderately strongly convex, oval, with barely discernible constriction between pronotum and elytra, moderately dark brown with slightly lighter tarsi, covered with light brown setae. BL 1.05–1.19 mm.

Head broadest across moderately large and moderately strongly convex, coarsely faceted eyes, HL 0.15 mm, HW 0.28 mm; frontovertexal region weakly convex at middle; supraantennal tubercles weakly elevated. Punctures on clypeus small but sharply marked, separated by spaces subequal to their diameters, frontovertexal region virtually impunctate; setae short, sparse and suberect. Antennae long and slender, gradually thickened, AnL 0.58–0.65 mm, antennomere 1 about as long as broad, 2 distinctly elongate, 3 about as long as broad, 4–7 each weakly elongate, 8 transverse, 9 and 10 each about as long as broad, 11 almost as long as 9 and 10 combined, about 1.6 × as long as broad.

Pronotum semi-oval, moderately strongly convex at middle and flattened near hind corners, equally broad between base and anterior third; PL 0.33–0.35 mm, PW 0.48–0.53 mm. Anterior margin in strictly dorsal view nearly straight; lateral margins strongly rounded in anterior third and straight posteriorly, 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 much closer to posterior than to lateral pronotal margin. Punctures on median region of pronotal disc small but sharply marked, separated by spaces subequal to their diameters. Setae on pronotal disc long and moderately dense, suberect.

Elytra about as wide as pronotum, together oval, broadest between middle and anterior third; EL 0.58–0.68 mm, EW 0.48–0.55 mm, EI 1.14–1.29; subhumeral lines developed as sharp borders between elevated humerus and lower mesal region, as long as 0.3 × EL and distinctly divergent posterad; basal elytral fovea on each elytron distinctly closer to lateral margin of mesoscutellum than to subhumeral line; elytral apices separately rounded. Punctures on elytra slightly larger than those on pronotum and similarly dense; setae short, moderately dense and suberect.

Hind wings in some specimens functional, in others lacking.

Metaventrite lacking lateral impressions.

Legs long and slender, unmodified.

Aedeagus ( Figs 182–183 View FIGURES 181–184 ) of modified simonis form, AeL 0.20 mm; in ventral view with capsular region of median lobe conspicuously small, as wide as long and truncate distally, in ventral view apical projections strongly elongate and strongly asymmetrical, in lateral view dorsal apical projection massive and curved ventrad, and dorsal apical projection also thick but straight; parameres of conspicuously uneven lengths, each with one moderately long apical and two slightly longer subapical setae.

Female. Externally indistinguishable from male; wingless; BL 1.15–1.18 mm; HL 0.15 mm, HW 0.28 mm, AnL 0.58–0.60 mm; PL 0.35–0.38 mm, PW 0.53–0.58 mm; EL 0.65 mm, EW 0.55 mm, EI 1.18.

Distribution. S China: Yunnan.

Etymology. The adjective dehongdaianus refers to the Dehong Dai and Jingpo Autonomous Prefecture, where the holotype was found.

Remarks. Cephennodes dehongdaianus can be easily identified by its unique aedeagus, impossible to confuse with any other species, but externally adults are very similar to C. yunnanensis ( Fig. 184 View FIGURES 181–184 ), the latter species having a slightly larger body.
