Reticuluma Cheng & Li

Reticuluma Cheng & Li, 2005: 379 –383.

Type species: Reticuluma citrana, Cheng & Li, 2005 .

Body flat, sloped anterad from the middle of pronotum. Covered with black or brown reticulation, forewings subhyaline.

Head small, slightly narrower than pronotum, with four black or orange spots, arranged in arc. Vertex shorter than the width between eyes, sloping to front and slightly extended beyond eye, numerous transverse stripes on apex extend to the base of postclypeus. Crown and face with obvious boundary. Ocelli on crown. Coronal suture about 2/3 length of vertex. Face black, distinctly wider than long, postclypeus flat, somewhat concave, antenna ledge developed.

Pronotum approximately 2× broader than median length, smooth; posterior margin straight or incurved medially; lateral margin long, carina present, nearly straight ventrally. Scutellum distinctly shorter than pronotum, basal width longer than medial length; transverse depression distinct with two milky or yellowish white spots on ends. Forewing elongate, subhyaline; with some supernumerary costal crossveins and many false veins consisting of dark pigment lines; crossvein present between claval veins, some species with short setae on subcostal vein; appendix well developed but narrow; five apical cells with small brown or black spots( Figs. 5A–C ). Fore femur with short dorsal setae, AM1 strong, AV1 and IC morderately strong( Fig. 5 D). Fore tibia with dorsal and ventral surface flattened obliquely; AD and PD setae sparse; AV setae dense ( Fig. 5 E). Macrosetal formula of hind femur apex 2+2+1, also with short subapical setae ( Fig. 5 F). Hind tibia flattened; AD setae very strong with several short setae between larger setae; PV setae dense ( Fig. 5 G). Hind tarsomeres I and II truncate distally, each with transverse row of blunt setae ( Fig. 5 H).

Male pygofer quadrate in lateral view with short and long macrosetae near posterior margin ( Figs. 3A, 3 I, 4A). Connective ‘Y’ or ‘T’ shaped. Style apex cheliform with well developed preapical lobe and slender, laterally curved apophysis; preapical lobe with several setae near inner margin ( Figs. 3E–F , 4D–E, 4 I).

Distribution. China (Shaanxi, Yunnan, Guizhou, Hunan, Zhejiang, Jiangxi, Anhui, Fujian, Guangdong).
