ABSTRACT
Two new species of Varma Distant, 1906, V. falcata Chang & Chen, sp. n. (China: Guizhou) and V. lobata Chang & Chen, sp. n. (China: Guizhou) are described and illustrated. The female genitalia of four speices including two known species are described and illustrated for the first time. The diagnostic characters of this genus are redefined. A checklist to the species of Varma in China is given. The Keys on male and female genitalia to the Chinese species of Varma are provided.

Dorsal habitus of Varma species. 1Varma falcata Chang & Chen, sp. n.; 2Varma lobata Chang & Chen, sp. n.; 3Varma gibbosa Wang & Liang; 4Varma serrata Men & Qin. Scale bars = 1.0 mm.

Figure 1: Dorsal habitus of Varma species. 1Varma falcata Chang & Chen, sp. n.; 2Varma lobata Chang & Chen, sp. n.; 3Varma gibbosa Wang & Liang; 4Varma serrata Men & Qin. Scale bars = 1.0 mm.

Mentions: Body slender, somewhat dorsoventrally depressed. Head (Figs 1–4, 5, 24) produced in front of eyes. Vertex (Figs 1–4, 5, 24) shorter in middle than broad at base (about 2.1–4.8:1), disc depressed, unicarinate carina, not reaching anterior margin. Frons (Figs 6, 25) unicarinate, longer in middle line than wide than broad (about 1.3–1.5:1). Pronotum (Figs 5, 24) tricarinate, wider than long in middle (about 3.1-5.0:1). Mesonotum (Figs 5, 24) tricarinate, wider than long in middle (about 1.1–1.3:1). Hind tibia with 3 lateral spines, spinal formula of hind leg 6(5)-5-2. Forewing (Figs 1–4, 8, 27) subhyaline, about 2.5 times longer than the widest breadth, corium without granulation, costal cell with various oblique transverse veins, nodal line and subapical line distinct. Male genitalia (Figs 10–15, 29–34) with pygofer asymmetrical, irregularly subquadrate, posterior marging produced various lobes; anal tube (urite X) symmetrical, anal styles (paraproct and epiproct) relative small, not surpassing apex of anal tube; gonostyli asymmetrical, with a strong stout process in left side, with a small process in right side; fused basally, with various median processes in ventral view; aedeagus tubular, expanded apex, with several lobes or band processes.
