description: Tenuicapitis gen. n.
Type species: Tenuicapitis xizangensis sp. n.
Diagnosis. The new genus differs from other Penthimiini as follow: crown distinctly produced with bicarinate marginal rim overhanging flat frontoclypeus, ocelli on crown near anterior margin well separated from eyes; dorsal color pattern reticulate, forewing with many false veins; male subgenital plate with sublateral row of macrosetae; style apex slender.
Description. Head in profile thin, anterior margin rimmed with two carinae, produced in dorsal view; crown longer than half distance between eyes, and shorter than median length of pronotum; ocelli located at side of crown, closer to corresponding eye than to apex of crown; lateral frontal sutures reaching ocelli; coronal suture about 1/3 length of vertex. Clypeus flat, broadening dorsally; clypellus pear-shaped, ridged medially, truncate at apex; lorum flat; antennal ledge developed. Pronotum approximately 2× broader than median length, smooth; posterior margin weakly concave; lateral margin long, carina present, nearly straight ventrally. Scutellum broadly triangular with transverse median impression distinct. Forewing elongate, semi-opaque, fine dark brown reticulations; appendix developed; with five apical and three ante-apical cells (Fig. 1A). Hind wing with four distal apical cells (Fig. 1B). Fore femur with short dorsal setae, AM1 strong, situated near ventral margin; AD1 slender and long; IC with row of fine setae (Fig. 1C); front tibia with about 8 and 17 setae in rows AD and AV, respectively (Fig. 1D). Macrosetal formula of hind femur apex 2+2+1 (Fig. 1E); hind tibia with AD setae very strong with several short setae between larger setae; AV and PV setae dense (Fig. 1F); hind tarsomeres I and II truncate distally, each with transverse row of blunt setae (Fig. 1G).
Male pygofer with some macrosetae near posterior margin. Valve nearly rectangular. Subgenital plate nearly triangular with four to five sublateral macrosetae. Connective short, Y-shaped. Style slender distally with series of setae on lateral margin.
Remarks. This genus has some resemblance to Chanohirata Hayashi & Machida and Uzelina Melichar, but differs in having thin head in lateral view compared to thicker head in both latter genera. This new genus is also similar to Tambila Distant, but differs in having slender body, distinct produced head in dorsal view, forewing with five apical cells, a longer style and more complex shape of the aedeagus.
Etymology. This genus name, a combination of the Latin “ tenuis ”, meaning “thin”, and “ caput ”, meaning “head”, refers to the head in profile thin. The gender is masculine.
Distribution. China (Xizang).
