Genus Chanohirata Hayashi & Machida

Chanohirata Hayashi & Machida, 1996: 69–70 . Type species: Penthimia theae Matsumura, 1912 .

Redescription. Dorsum covered with black or brown reticulation. Vertex shorter than width between eyes, sloping to front and slightly extended beyond eye, numerous transverse striations on apex extend to the base of postclypeus. Crown and face with obvious boundary; ocelli placed on crown toward middle, more remote from each other than from eyes. Face black, wider than long, postclypeus flat, antennal ledge developed. Pronotum broader than median length, anterior margin convex, posterior margin sinuate, lateral margins carinate. Scutellum shorter than pronotum, basal width longer than medial length. Forewing subhyaline, with some supernumerary costal cross veins and many false veins consisting of dark pigment lines; appendix developed but narrow. Fore femur with anteroventral (AV1) seta moderately strong, intercalary (IC) row with about 10–13 setae; AM1 seta large, situated near apex. Fore tibia with dorsal and ventral surface flattened obliquely; AD and PD setae sparse; AV setae dense. Hind femoral macrosetae 2+2+1. Hind tibia flattened; AD setae very strong with several short setae between larger setae; PV setae dense.

Male pygofer quadrate without process on apex in lateral view and with macrosetae near posterior margin. Connective ‘Y’ or ‘T’ shaped. Style with well developed preapical lobe, laterally curved apophysis; preapical lobe with several setae near inner margin.

Remarks. Chanohirata resembles Reticuluma Cheng & Li but differs from the latter in lacking a lateroapical process on the male pygofer. The genus also has some resemblance to Uzelina Melichar , particularly in the male genitalia, but the latter has the head spatulate in profile and lacking reticulate markings on the vertex compared to the thicker anterior part of head and reticulately marked vertex in Chanohirata . Prior to this study, Chanohirata was known only from the type species described from Japan. Here we transfer five species previously placed in Reticuluma to Chanohirata (see new combinations in Checklist below) and describe three new species of the genus. We also recognize one new synonym (see below).

Distribution. China (Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hainan, Henan, Hunan, Jiangxi, Shaanxi, Taiwan, Tibet, Yunnan, Zhejiang); Japan ( Fig. 5 ).
