Etymology.
The specific name is derived from the Latin flavus (yellow) and penna (feather), referring to its mostly yellow elytra.
Type material.
Holotype. China ‒ Guangxi Zhuang Autonomous Region • ♂, Longsheng ; 1800 m; 20-IV-1963; S. Y. Wang leg.; IZAS.
Paratypes. China ‒ Guangxi Zhuang Autonomous Region • 3 ♂♂; same data as holotype; IZAS .
Diagnosis.
The species resembles M. villosipes Y. Yang, Liu & X. Yang, 2024 , in the habitus and the general shape of aedeagus but could be easily differentiated from the latter by the following characters: antennae normally filiform in male (Fig. 14 C View Figure 14 ); mesotibiae never covered with longer hairs in male (Fig. 14 C View Figure 14 ); abdominal sternite VII without any bulges or long setae in male; aedeagus with left dorsal paramere (Fig. 18 E View Figure 18 ) about 0.7 times length of left ventral paramere. Unlike in M. villosipes , antennae cylindrically thickened in male ( Lin et al. 2024 a: fig. 9 a); male mesotibiae densely covered with longer and erected hairs in male ( Lin et al. 2024 a: fig. 8 a); abdominal sternite VII with one bulge covered with long setae in male ( Lin et al. 2024 a: fig. 8 b); aedeagus with left dorsal paramere 1.1 times longer than left ventral paramere ( Lin et al. 2024 a: fig. 6 e, f).
Description.
Body length: 5.2‒5.6 mm (5.6 mm in holotype); body width: 1.0‒ 1.3 mm (1.3 mm in holotype).
Male (Fig. 14 C View Figure 14 ). Coloration. Body black, but yellow at clypeus, antennomeres I ‒ III, scutellum, and apical half part and outer half part of elytra.
Eyes large, interocular distance about half as wide as diameter of an eye. Antennae extending to the middle of abdominal tergite II, antennomeres II about half length of I, III ‒ X subequal in length and about half length of I, XI about 1.3 times longer than X.
Pronotum 1.1 times wider than long, anterior margin slightly arcuate, posterior margin bisinuate, lateral margins subparallel, anterior angles rounded, and posterior angles nearly rectangular. Elytra 1.3 times longer than wide, 2.3 times longer than pronotum, with lateral margins sinuate, sutures strongly dehiscent from the base, distance between sutures wider than width of the elytron, apices rounded.
Abdominal tergite VIII (Fig. 15 B View Figure 15 ) about 1.3 times longer than wide, with lateral margins slightly arcuate, postero-lateral projections about 1 / 3 length of the tergite and arcuate at inner margins. Abdominal sternite VIII (Fig. 16 B View Figure 16 ) bilobed, with lateral portions diverging posteriorly from each other, broadly fused at basal half part, each with a sharply hooked projection at apex, a triangular protuberance at middle of inner margin, surface coarsely punctate and covered with a few erected and stout setae in middle part. Proctiger (Fig. 17 B View Figure 17 ) semicircular, almost surrounded by paraproct and covered with a few long pubescence on surface. Paraproct (Fig. 17 B View Figure 17 ) semicircular and obviously bordered at lateral margins, slightly emarginate in middle of posterior margin, around which covered with long pubescence, with tergal flange long and about 3.5 times as long as paraproct, basal 1 / 3 part strongly broadened and nearly oval, nearly as long than wide, apical 2 / 3 part slender and bent inwards.
Aedeagus (Fig. 18 E ‒ H View Figure 18 ): left ventral paramere slender and bisinuate in dorsal and ventral views, rounded at apex (Fig. 18 F, G View Figure 18 ); left dorsal paramere conical tube-shaped, short and about 0.6 times length of left ventral paramere, pointed at apex (Fig. 18 F View Figure 18 ); right paramere 1.1 times as long as left ventral paramere, narrowest in middle part, rounded at apex (Fig. 18 E, H View Figure 18 ); median lobe moderately sclerotized and as long as parameres, lamellar at basal part and elongate-tube shaped at apical half, rounded at apex (Fig. 18 F, G View Figure 18 ).
Female. Unknown.
Distribution.
China (Guangxi).
