Cephennodes (Fusionodes) brachyclavatus sp. nov. (Figs 222–225) Type material. Holotype: CHINA (YUNNAN Prov.): ♂, two labels:“CHINA: Yunnan, SE Pingbian, / 22º54’31’’N, 103º41’44’’E, 2100 m / primary subtropical broad-leaved / forest, litter sifted / 27.VIII.2014, / leg. M. Schülke [CH14-22]” [white, printed]; “ CEPHENNODES / (FUSIONODES) / brachyclavatus m. / P. Jałoszyński, 2025 / HOLOTYPUS ” [red, printed] (MNB). Diagnosis. Body small, BL around 1.2mm; antennae conspicuously short and with strongly thickened tetramerous clubs; punctures on clypeus virtually absent, a few small but sharply marked punctures present on median area of frontovertexal region and unevenly distributed, lateral areas of frontovertexal region with similar but much denser punctures separated by spaces shorter than their diameters, punctures on median region of pronotal disc indistinctly smaller than those on head but also sharply marked, separated by spaces subequal to their diameters, punctures on elytra fine and inconspicuous; subhumeral lines short, as long as 0.3 × EL. Male: aedeagus (Figs 223–225) in ventral view with capsular region of median lobe with broadly and shallowly emarginate distal margin, apex of apical projection shallowly and narrowly emarginate, and parameres not projecting distad beyond capsular region. Description. Body of male (Fig. 222) moderately strongly convex, oval, with barely discernible constriction between pronotum and elytra, dark brown with slightly lighter tarsi, covered with light brown setae. BL 1.25 mm. Head broadest across 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 virtually absent, a few small but sharply marked punctures present on median area of frontovertexal region and unevenly distributed, lateral areas of frontovertexal region with similar but much denser punctures separated by spaces shorter than their diameters; setae short, sparse and suberect. Antennae conspicuously short and strongly thickened distad, with tetramerous clubs, AnL 0.58 mm, antennomere 1 about as long as broad, 2 distinctly elongate, 3–10 each transverse (8–10 strongly so), 11 about as long as 9 and 10 combined, about 1.3 × as long as broad. Pronotum semi-oval, moderately strongly convex at middle and flattened near anterior and hind corners, equally broad between base and near middle; PL 0.40 mm, PW 0.53 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 indistinctly smaller than those on head but also sharply marked, separated by spaces subequal to their diameters, punctures near anterior and posterior corners much denser and slightly coarse; setae short and moderately dense, suberect. Elytra about as wide as pronotum, together oval, broadest near anterior third; EL 0.70 mm, EW 0.55 mm, EI 1.27; subhumeral lines developed as sharp borders between elevated humerus and lower mesal region, as long as 0.3 × 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 lacking. Metaventrite with lateral impressions as long as 1/3 of its length. Legs moderately long and slender, unmodified. Aedeagus (Figs 223–225) AeL 0.43 mm; in ventral view with capsular region of median lobe with broadly and shallowly emarginate distal margin; subapical lateral lobes not projecting beyond lateral margins of capsular region; apex of apical projection shallowly and narrowly emarginate, its lateral margins weakly sinuate and narrowing from base of projection to apex; in lateral view apical projection short and broadening distad, subapical dorsal projection about as long as apical projection; parameral apices in ventral view not projecting distad beyond capsular region, slender and each with one long apical seta. Female. Unknown. Distribution. S China: Yunnan. Etymology. The adjective brachyclavatus refers to the unusually short antennae in relation to the body length. Remarks. Cephennodes brachyclavatus and C. microphthalmus are the only members of this group with adults reaching less than 1.4 mm in length. They differ clearly in external morphology. Cephennodes brachyclavatus has conspicuously short and strongly thickened antennae and large eyes, whereas C. microphthalmus has long and slender antennae and strongly reduced eyes; aedeagi of these species also strongly differ, especially in lateral view.
