Cephennodes (Fusionodes) microsoma sp. nov.

( Figs 202–205 View FIGURES 202–209 )

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 / 28.VIII.2014, / leg. M. Schülke [ CH14-22 a]” [white, printed]; “ CEPHENNODES / ( FUSIONODES ) / microsoma m. / P. Jałoszyński, 2025 / HOLOTYPUS ” [red, printed] ( MNB) GoogleMaps . Paratype: 1 ♂, same data as for holotype, with yellow GoogleMaps PARATYPUS labels (cPJ).

Diagnosis. Body moderately large, BL around 1.4–1.5 mm; antennae gradually thickened; punctures on clypeus and frontovertexal region fine but distinct, sharply marked and separated by spaces subequal to their diameters, punctures on median region of pronotal disc similar to those on head, those on elytra fine and inconspicuous; subhumeral lines short, as long as 0.3 × EL. Male: aedeagus ( Figs 203–205 View FIGURES 202–209 ) in ventral view with capsular region of median lobe with bifurcate distal margin; subapical lateral lobes subtriangular and about as long as broad; apical lateral projections touching at middle only with their apices; in dorsal view proximal subapical dorsal projection with broadly and shallowly emarginate distal margin; in lateral view apical lateral projection vertical and proximal subapical dorsal projection bent apically at right angle; each paramere with two setae.

Description. Body of male ( Fig. 202 View FIGURES 202–209 ) strongly convex, oval, with shallow but distinct constriction between pronotum and elytra, moderately dark brown with slightly lighter tarsi, covered with light brown setae. BL 1.43– 1.45 mm.

Head broadest across large and moderately strongly convex, coarsely faceted eyes, HL 0.20 mm, HW 0.35 mm; frontovertexal region weakly convex at middle; supraantennal tubercles weakly elevated. Punctures on clypeus and frontovertexal region fine but distinct, sharply marked and separated by spaces subequal to their diameters; setae short, sparse and suberect. Antennae long and slender, gradually thickened, AnL 0.68–0.75 mm, antennomere 1 about as long as broad, 2 distinctly elongate, 3–10 each transverse, 11 indistinctly longer than 9 and 10 combined, about 1.7 × as long as broad.

Pronotum semi-oval, strongly convex at middle and flattened near anterior and hind corners, broadest near middle and weakly narrowing posterad; PL 0.43–0.45 mm, PW 0.60–0.63 mm.Anterior margin in strictly dorsal view nearly straight; lateral margins strongly rounded in anterior half 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 fine but distinct, sharply marked and separated by spaces subequal to their diameters, punctures near anterior corners much denser and somewhat coarse; setae short and moderately dense, suberect.

Elytra distinctly wider than pronotum, together oval, broadest near anterior third; EL 0.80 mm, EW 0.70– 0.68 mm, EI 1.14–1.19; subhumeral lines developed as sharp borders between elevated humerus and lower mesal region, as long as 0.30 × EL and strongly divergent posterad; basal elytral fovea on each elytron slightly closer to lateral margin of mesoscutellum than to subhumeral line; elytral apices separately rounded. Punctures on elytra fine and inconspicuous; setae similar to those on pronotum.

Hind wings functional.

Metaventrite lacking lateral impressions.

Legs long and slender, unmodified.

Aedeagus ( Figs 203–205 View FIGURES 202–209 ) AeL 0.48 mm; in ventral view with capsular region of median lobe with bifurcate distal margin developed as pair of subtriangular lobes separated by U-shaped emargination; subapical lateral lobes subtriangular and each about as long as broad; apical lateral projections with convex lateral margins, except for short subapical concave area, touching at middle only with apices; in dorsal view proximal subapical dorsal projection subtrapezoidal and with broadly and shallowly emarginate distal margin; in lateral view apical lateral projection vertical and distally angulate, proximal subapical dorsal projection bent apically at right angle; parameral apices in ventral view straight and parallel to long axis of aedeagus, each with two setae.

Female. Unknown.

Distribution. S China: Yunnan.

Etymology. The noun microsoma refers to the relatively small body as for a member of a typically large-bodied subgenus.

Remarks. Cephennodes microsoma is the only member of the C. hippopotamus species group that has the aedeagus in lateral view with a long proximal subapical dorsal projection distally bent at a right angle.
