Diagnosis. Body small, BL around 1.3 mm; antennae gradually thickened; punctures on median region of clypeus virtually absent, few distinct punctures present on lateral regions of clypeus, punctures on median area of frontovertexal region small but distinct, sharply marked and separated by spaces slightly wider than their diameters, those on lateral areas of frontovertexal region distinctly denser, separated by spaces subequal to their diameters, punctures on median region of pronotal disc and on elytra barely discernible and separated by spaces subequal to their diameters; subhumeral lines short, as long as 0.25 × EL. Male: aedeagus ( Figs 219–221 View FIGURES214–221 ) in ventral view with capsular region of median lobe with subtrapezoidal distal margin, its median portion straight, distal margin in lateral view with deep U-shaped emargination; subapical dorsal projection in dorsal view somewhat angulate in submedian region, in lateral view with weakly concave dorsal margin.

Description. Body of male ( Fig. 218 View FIGURES214–221 ) strongly convex, oval, with shallow and indistinct constriction between pronotum and elytra, moderately dark brown with slightly lighter tarsi, covered with light brown setae. BL 1.35 mm.

Head broadest across large and moderately strongly convex, coarsely faceted eyes, HL 0.18 mm, HW 0.31 mm; frontovertexal region weakly convex at middle; supraantennal tubercles weakly elevated. Punctures on median region of clypeus virtually absent, few distinct punctures present on lateral regions of clypeus, punctures on median area of frontovertexal region small but distinct, sharply marked and separated by spaces slightly wider than their diameters, those on lateral areas of frontovertexal region distinctly denser, separated by spaces subequal to their diameters; setae short, sparse and suberect. Antennae long and slender, gradually thickened, AnL 0.65 mm, antennomere 1 about as long as broad, 2 distinctly elongate, 3–7 each about as long as broad, 8–10 each slightly transverse, 11 about as long as 9 and 10 combined, about 1.8 × as long as broad.

Pronotum semi-oval, strongly convex at middle and flattened near anterior and hind corners, equally broad between base and near middle; PL 0.40 mm, PW 0.60 mm. Anterior margin in strictly dorsal view nearly straight; lateral margins strongly rounded in anterior third and nearly 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 nearly equidistant to posterior and lateral pronotal margin. Punctures on median region of pronotal disc barely discernible and separated by spaces subequal to their diameters, punctures near anterior corners much denser and slightly coarse; setae short and moderately dense, suberect.

Elytra indistinctly wider than pronotum, together oval, broadest near anterior third; EL 0.78 mm, EW 0.63 mm, EI 1.24; 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 nearly equidistant to lateral margin of mesoscutellum and subhumeral line; elytral apices separately rounded. Punctures on elytra similar to those on median region of pronotum but slightly larger and less distinct; setae similar to those on pronotum.

Hind wings functional.

Metaventrite lacking lateral impressions.

Legs long and slender, unmodified.

Aedeagus ( Figs 219–221 View FIGURES214–221 ) AeL 0.40 mm; in ventral view capsular region of median lobe with subtrapezoidal distal margin, its median portion straight, distal margin in lateral view with deep U-shaped emargination; subapical dorsal projection in dorsal view parallel-sided proximally, somewhat angulate in submedian region, and gradually narrowing distad in distal half, in lateral view with weakly concave dorsal margin; parameres indiscernible.

Female. Unknown.

Distribution. S China: Yunnan.

Etymology. The adjective linguatoides is derived from the species name C. linguatus .

Remarks. Within the C. longilinguis group, C. linguatoides can be identified by the following combination of characters: in lateral view, the subapical dorsal projection much longer than apical lateral projection, and distal margin of capsular region of median lobe with deep U-shaped emargination; in ventral view, distal region of aedeagus almost as long as wide.
