Cephennodes (Fusionodes) brachycornis sp. nov. (Figs 210–213) Type material. Holotype: CHINA (YUNNAN Prov.): ♂, two labels: “CHINA (Yunnan) Pu’er Pref., / Ailao Shan, 37 km NW Jingdong / 24º45’12’’N / 100º41’24.5’’N {sic!} / 2300 m (devastated forest rem- / nant, litter/moss/grass roots sifted / 13.IX.2009 D.W.Wrase [48]” [white, printed]; “ CEPHENNODES / (FUSIONODES) / brachycornis m. / P. Jałoszyński, 2025 / HOLOTYPUS ” [red, printed] (MNB). Diagnosis. Body large, BL around 1.8 mm; antennae gradually thickened; punctures on clypeus virtually absent, on frontovertexal region fine but distinct, sharply marked and these on lateral regions separated by spaces slightly shorter than their diameters, those on median area distinctly sparser, punctures on median region of pronotal disc slightly smaller than on head but distinct and separated by spaces subequal to their diameters, those on elytra fine and inconspicuous; subhumeral lines short, as long as 0.3 × EL. Male: aedeagus (Figs 211–213) in ventral view with capsular region of median lobe with straight distal margin; subapical lateral lobes lacking; apical lateral projections not touching at middle; proximal and distal subapical dorsal projections rudimentary, each visible in lateral view as minute subtriangular convexity; in lateral view apical lateral projection strongly bent dorsad and subtriangular; each paramere with two setae. Description. Body of male (Fig. 210) strongly convex, oval, with shallow but distinct constriction between pronotum and elytra, dark brown with slightly lighter tarsi, covered with light brown setae. BL 1.78 mm. Head broadest across large and 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 lacking, those on frontovertexal region fine but distinct, sharply marked and on lateral regions separated by spaces slightly shorter than puncture diameters, those on median area distinctly sparser; setae short, sparse and suberect. Antennae long and slender, gradually thickened, AnL 0.88 mm, antennomere 1 about as long as broad, 2 weakly elongate, 3–6 each indistinctly transverse, 7 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, broadest near middle but indistinctly narrowing posterad; PL 0.55 mm, PW 0.78 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 small but distinct and separated by spaces subequal to their diameters, punctures near anterior and posterior corners much denser and coarse; setae short and moderately dense, suberect. Elytra slightly wider than pronotum, together oval, broadest near anterior third; EL 0.98 mm, EW 0.83 mm, EI 1.18; subhumeral lines developed as sharp borders between elevated humerus and lower mesal region, as long as 0.30 × 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 fine and inconspicuous; setae similar to those on pronotum. Hind wings vestigial. Metaventrite with lateral impressions as long as 3/4 of its length. Legs long and slender, unmodified. Aedeagus (Figs 211–213) AeL 0.50 mm; in ventral view capsular region of median lobe nearly parallel-sided, with broadly subtrapezoidal distal portion and distal margin straight at middle; subapical lateral lobes lacking; apical projections in ventral view subtriangular and much narrower than capsular region of median lobe; apical lateral projections not touching at middle; proximal and distal subapical dorsal projections vestigial, each visible in lateral view as minute subtriangular convexity; in lateral view apical lateral projection strongly bent dorsad and subtriangular; each paramere with two setae. Female. Unknown. Distribution. S China: Yunnan. Etymology. The adjective brachycornis refers to the relatively short antennae. Remarks. Cephennodes brachycornis is the only member of the C. hippopotamus species group that has the aedeagus in ventral view with the capsular region parallel-sided instead of distinctly narrowing distad.
