Genus Reticuluma Cheng & Li

Reticuluma Cheng & Li, 2005: 379–383 ; Fu & Zhang, 2015: 253–260 ; Wang & Zhang, 2019: 289–295 ; Xu, Yu, Dai & Yang, 2020: 177–186 . Type species: Reticuluma citrana Cheng & Li, 2005 .

Redescription: Body flat, sloped anterad from the middle of pronotum. Covered with black or brown reticulation. Crown slightly narrower than pronotum; coronal suture length about 3/5 of crown; ocelli located on crown, closer to eyes than to each other. Postclypeus slightly convex, anteclypeus flat and truncate at apex. Pronotum length 1.5 times medial length of crown, anterior margin convex, posterior margin transverse. Scutellum basal width longer than medial length. Forewing elongate, with many false veins consisting of dark pigment lines; crossvein present between claval veins, some species with short setae on subcostal vein; appendix developed.

Pygophore longer than high, posterior margin rounded with a short apical process. Valve triangular. Subgenital plate extending beyond apex of pygofer, nearly triangular. Connective ‘Y’ shaped; stem slightly longer than anterior arms. Style with developed preapical lobe, apical fingerlike, curved laterally; preapical lobe with several setae near inner margin. Aedeagal shaft with pair of preapical processes.

Remarks. Examination of specimens of species previously included in Reticuluma Cheng & Li revealed that this genus, as previously defined, is very similar to Chanohirata in overall body size, structure, coloration and male genitalia. However, the male pygofer of the type species of Reticuluma differs from other species included in the genus in having an obvious process on the lateroapical margin. Hence, we restrict the definition of Reticuluma to include only the type species and transfer all other species previously included in Reticuluma to Chanohirata : C. bipennata (Xu, Yu, Dai & Yang) comb. nov., C. dactyla (Fu & Zhang) comb. nov., C. eurya (Fu & Zhang) comb. nov., C. hamata (Wang & Zhang) comb. nov., C. lini (Cheng & Li) comb. nov., C. lageniformia (Wang & Zhang) comb. nov. and C. spinata (Cheng & Li) comb. nov., Reticuluma testacea ( Kuoh, 1991) syn. nov. of C. theae ( Matsumura, 1912) .
