Cephennodes (s. str.) pseudopalpalis sp. nov.

( Figs 125, 127–129 View FIGURES 124–133 )

Type material. Holotype: CHINA ( YUNNAN Prov.): ♂, two labels: “CHINA: Yunnan / Nujiang Lisu Aut. Pref., / Salween side valley 5km S / Fugong, road SS 228, / km 223 (creek bank, litter sifted) / 8.VI.2007 D.W. Wrase [25]” [white, printed]; “ CEPHENNODES (s. str.) / pseudopalpalis m. / P. Jałoszyński, 2025 / HOLOTYPUS ” [red, printed] ( NKME).

Diagnosis. Body small, BL around 1.15 mm; antennae gradually thickened; punctures on head and pronotum fine and inconspicuous, those on adsutural half of each elytron distinct, sharply marked and conspicuously dense, separated by spaces slightly narrower than their diameters, punctures becoming smaller towards lateral and posterior elytral margins; subhumeral lines short, as long as 0.2 × EL; elytra with conspicuous setal pattern: setae on densely punctate adsutural halves directed posterad, those on outer halves directed laterad. Male: lacking secondary sexual characters (unless setal elytral pattern is such a character); aedeagus ( Figs 128–129 View FIGURES 124–133 ) in ventral view with nearly straight and conspicuously narrow apical region of capsular portion pointed at apex; distal margin of apical plate nearly straight.

Description. Body of male ( Fig. 127 View FIGURES 124–133 ) strongly convex, oval, with very shallow constriction between pronotum and elytra, light brown with slightly lighter tarsi, covered with yellowish brown setae. BL 1.13 mm.

Head broadest across moderately 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 and frontovertexal region fine and inconspicuous; setae short, sparse, suberect. Antennae long and slender, gradually and strongly thickened, AnL 0.60 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 longer than 9 and 10 combined, about 1.8 × as long as broad.

Pronotum semi-oval, moderately strongly convex at middle and flattened near hind corners, equally broad between base and middle; PL 0.35 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 almost equidistant to posterior and lateral pronotal margin. Punctures on pronotal disc fine and inconspicuous; setae on pronotal disc short and moderately dense, suberect.

Elytra as wide as pronotum, together oval, broadest near anterior third; EL 0.63 mm, EW 0.50 mm, EI 1.25; subhumeral lines marked as borders between lower mesal and elevated humeral regions, only as long as about 0.2 × EL and distinctly divergent posterad; basal elytral fovea on each elytron situated at middle between lateral margin of mesoscutellum and subhumeral line; elytral apices separately rounded. Punctures on elytra conspicuously distinct, those on mesal half of each elytron small but sharply marked and appearing somewhat coarse, separated by spaces smaller than puncture diameters, punctures gradually becoming smaller and shallower towards lateral and posterior elytral margins; setae forming conspicuous patter, those on densely punctate adsutural halves directed posterad and suberect, those on outer halves directed laterad and erect.

Hind wings functional.

Metaventrite with lateral impressions about as long as 3/4 of its length.

Legs long and slender, unmodified.

Aedeagus ( Figs 128–129 View FIGURES 124–133 ) of modified simonis form, AeL 0.20 mm; capsular region of median lobe in ventral view drop-shaped with moderately strongly elongate and conspicuously narrow distal region tapering towards pointed apex; dorsal apical projection (= distal plate) in ventral view with nearly straight distal (oblique) margin; parameres long and slender, not reaching apex of aedeagus, each with one short apical and two similarly short subapical setae.

Female. Unknown.

Distribution. S China: Yunnan.

Etymology. The adjective pseudopalpalis refers to the similarity to C. palpalis .

Remarks. Cephennodes pseudopalpalis clearly differs from C. palpalis ( Fig. 133 View FIGURES 124–133 ) in a much stouter body, and from C. micrus described below in less convex lateral margins of elytra. All three species have clearly different aedeagi, although representing variations of the same form.
