Cephennodes parvus Jałoszyński, 2025, sp. nov.

Cephennodes (s. str.) parvus sp. nov. (Figs 148–150) Type material. Holotype: CHINA (YUNNAN Prov.): ♂, two labels: “CHINA mer.: Yunnan prov. / (pass SW from Baoshan / Gaoligong Shan) / 4. - 8.6.2005 / sporocarp of mycetes / Oto Nakladal lgt.” [white, printed]; “ CEPHENNODES (s. str.) / parvus m. / P. Jałoszyński, 2025 / HOLOTYPUS ” [red, printed] (MNHW). Paratype: 1 ♀, same data as for holotype, and with yellow PARATYPUS label (cPJ). Diagnosis. Body very small, BL around 1 mm; antennae gradually thickened; punctures on clypeus virtually absent, on frontovertexal region small but sharply marked and dense, slightly denser near mesal margins of eyes than at middle, on median area separated by spaces slightly wider, and near eyes slightly narrower than their diameters, pronotum and elytra with fine, inconspicuous punctures; subhumeral lines as long as 0.3 × EL. Male: lacking secondary sexual characters; aedeagus (Figs 149–150) in ventral view with subtriangular capsular region of median lobe, its distal portion projecting into elongate subtriangular and apically rounded process, apical projection much wider than long, subtriangular, broadly separated from apex of capsular region. Description. Body of male (Fig. 148) 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 1.05 mm. Head broadest across moderately large and moderately strongly convex, coarsely faceted eyes, HL 0.13 mm, HW 0.25 mm; frontovertexal region weakly convex at middle; supraantennal tubercles weakly elevated. Punctures on clypeus virtually absent, on frontovertexal region small but sharply marked and dense, on median area separated by spaces slightly wider, and near eyes slightly narrower than their diameters; 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 strongly elongate, 3–7 each about as long as broad, 8–10 each weakly transverse, 11 slightly shorter than 9 and 10 combined, about 1.6 × 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 0.45 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 nearly equidistant to lateral and posterior pronotal margin. Punctures on pronotal disc fine and inconspicuous; setae short and moderately dense, suberect. Elytra slightly wider than pronotum, together oval, broadest near anterior third; EL 0.60 mm, EW 0.50 mm, EI 1.20; 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 3/4 of its length. Legs long and slender, unmodified. Aedeagus (Figs 149–150) of simonis form, AeL 0.13 mm; capsular region of median lobe in ventral view subtriangular, its distal portion projecting into elongate subtriangular and apically rounded process, apical projection much wider than long, subtriangular, 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 0.95 mm; HL 0.13 mm, HW 0.25 mm, AnL 0.50 mm; PL 0.20 mm, PW 0.48 mm; EL 0.63 mm, EW 0.50 mm, EI 1.25. Distribution. S China: Yunnan. Etymology. The Latin adjective parvus means little, small. Remarks. Within the C. simonis group, C. parvus is most similar to C. aliusmodi. They both share the aedeagi with a subtriangular capsular region of median lobe, and a subtriangular apical projection broadly separated from the capsular region. In C. aliusmodi, the apical projection is much longer than that in C. parvus (elongate vs. wider than long), and exceeds the apex of capsular region, whereas in C. parvus the apex of capsular region projects beyond apex of the projection.
