( Figs 145–147 View FIGURES 142–150 )

Type material. Holotype: CHINA (YUNNAN Prov.): ♂, two labels: “CHINA: Yunnan, Baoshan Pref., Gao- / ligong Shan, W pass 35 km SE / Tengchong , 2100 m, 24º50’18’’N, / 95º45’43’’E, devast. prim. dec. forest, / litter, wood, mushrooms sifted, 25.VII. / 2009, leg. M. Schülke [ CH09-06 ]” [white, printed]; “ CEPHENNODES (s. str.) / aliusmodi m. / P. Jałoszyński, 2025 / HOLOTYPUS ” [red, printed] ( MNB) GoogleMaps . Paratype: 1 ♀, same data as for holotype, and with yellow GoogleMaps PARATYPUS label (cPJ).

Diagnosis. Body very small, BL around 1.1 mm; antennae gradually thickened; punctures on head, pronotum and elytra fine, inconspicuous; subhumeral lines as long as 0.3 × EL. Male: lacking secondary sexual characters; aedeagus ( Figs 146–147 View FIGURES 142–150 ) in ventral view with subtriangular capsular region of median lobe, its distal portion projecting into elongate triangular and apically angulate process, apical projection elongate, subtriangular, broadly separated from apex of capsular region.

Description. Body of male ( Fig. 145 View FIGURES 142–150 ) moderately strongly convex, oval, with shallow but distinct constriction between pronotum and elytra, moderately light brown with lighter tarsi, covered with light brown setae. BL 1.08 mm.

Head broadest across moderately large and moderately strongly convex, coarsely faceted eyes, HL 0.13 mm, HW 0.28 mm; frontovertexal region weakly convex at middle; supraantennal tubercles weakly elevated. Punctures on clypeus and frontovertexal region fine and inconspicuous; setae sparse, short, suberect. Antennae moderately long and slender, gradually and moderately strongly thickened, AnL 0.53 mm, antennomere 1 about as long as broad, 2 distinctly elongate, 3–7 each about as long as broad, 8–10 each weakly transverse, 11 slightly shorter than 9 and 10 combined, about 1.7 × as long as broad.

Pronotum semi-oval, strongly convex at middle and flattened near hind corners, equally broad between base and middle; PL 0.33 mm, PW 0.50 mm. Anterior margin in strictly dorsal view nearly straight; lateral margins strongly rounded in anterior half 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 distinctly closer to lateral than posterior pronotal margin. Punctures on pronotal disc fine and inconspicuous; setae short and moderately dense, suberect.

Elytra as wide as pronotum, together oval, broadest between middle and anterior third; EL 0.63 mm, EW 0.50 mm, EI 1.25; subhumeral lines as long as about 0.3 × EL, developed as sharp borders between elevated humerus and lower mesal region, weakly divergent posterad; basal elytral fovea on each elytron situated slightly closer to lateral margin of mesoscutellum than to subhumeral line; elytral apices separately rounded. Punctures on elytra superficial and inconspicuous; setae similar to those on pronotum.

Hind wings functional.

Metaventrite with distinct lateral impressions as long as about half its length.

Legs long and slender, unmodified.

Aedeagus ( Figs 146–147 View FIGURES 142–150 ) of simonis form, AeL 0.15 mm; capsular region of median lobe in ventral view subtriangular, its distal portion projecting into elongate triangular process, apical projection elongate, subtriangular, with narrow distal portion, broadly separated from apex of capsular region; parameres long and slender, not reaching apex of aedeagus, each with one moderately long apical seta.

Female. Externally indistinguishable from male; wings not studied. BL 1.10 mm; HL 0.15 mm, HW 0.25 mm, AnL 0.50 mm; PL 0.33 mm, PW 0.50 mm; EL 0.63 mm, EW 0.53 mm, EI 1.19.

Distribution. S China: Yunnan.

Etymology. The Latin alius -modi (modi being a noun) means “of another kind”.

Remarks. Within the C. simonis group, C. aliusmodi is the only species with narrowly subtriangular apical projection in ventral view projecting distad further than apex of capsular region and parallel to it, but these two structures are widely separated.
