Varma lobata Chang & Chen sp. n. Figs 2, 24-34
Holotype: ♂, China: Yunnan, Jinping Fenshuiling Native Nature Reserve (22°46'N, 103°14'E), 7 July 2012, W.-B. Zheng; paratypes: 4 ♂♂, 6 ♀♀, same data as holotype.
Body length (from apex of vertex to tip of forewings): male 9.2-9.5 mm (N = 6), female 11.1-11.8 mm (N = 4).
Coloration. General color pale green to greenish-yellow. Vertex, pronotum, mesonotum pale green. Forewings light green, marked with irregular brown spots at the base and middle and around nodal line, with 3-4 ranks of fine speckles and suffused fuscous between apical margin and the first subapical line.
Head and thorax. Vertex (Fig. 24) distinctly broader than long in middle line (4.8:1). Frons (Fig. 25) longer in middle than widest breadth (1.3:1), widest at apical fourth. Pronotum (Fig. 24) obviously wider than long in middle (4.5:1). Mesonotum (Fig. 24) wider than long in middle (1.2:1). Forewing about 2.4 times longer than the widest, venations as in Fig. 27. Hind wing with venation as in Fig. 28. Spinal formula of hind leg 6 (5)-5-2.
Male genitalia. Male genitalia (Figs 29-34) with pygofer not bilaterally symmetrical, in proflile left view, irregularly stomach-like, posterior margin produced caudad with a lobe near its upper end; in right side, irregularly subquadrate, posterior margin producrd into strip directed caudoventrad (Figs 29, 31, 32). Anal tube (urite X) (Figs 31, 32) symmetrical, not surpassing apex of aedeagus in lateral view, anal styles relatively small, not surpassing apex of anal tube. In ventral view, gonostyli (Figs 29, 30, 33) with basal 3/4 fused together, medially produced into sub-semicircular lobe. Aedeagus (Figs 29, 34) tubular, relatively long, narrow at base and distinctly expanded apex, splitting into two lobe plates, directed into dorsal margins, both with serrated margins, of one prongy in left view, of one sub-oblong lobe in right side, with 3-4 denticulate structure in ventral margins near basal 2/3. Periandrium fissure-like, exposed in middle. Corpus connectivi stout, rod-like.
Female genitalia. Gonapophyses VIII (first valvula) (Fig. 35) saw-like, strongly sclerotized with 7 distinct teeth on dorsal margin, ventral margin with 3-4 distinct teeth. Gonapophyses IX (second valvula) (Fig. 37) degradated, triangular. Gonoplace (third valvula) (Fig. 38) stout, membranous, formed 12 or 13 teeth on ventral margin and apical margin. In ventral view, endogonocoxal lobe (Fig. 36) in the base of the gonapophyses VIII produced mesad irregular triangle, that of left more narrow, that of right more broader. Sternite VII (Fig. 36) with posterior margin forming a pit in middle 1/2.
The name of the new species results from apex of aedeagus, splitted into two lobe plates.
This new species can be distinguished from other species in the genus by the following combination of characters: (1) Gonostyli with a sub-semicircular lobe at apically inner margin (Fig. 30). (2) Apex of aedeagus, splitted into two lobe plates, directed into dorsal margins, of one sub-oblong lobe, of one sub-oblong lobe, with 3-4 denticulate structure in ventral margins near basal 2/3 (Fig. 34). (3) Pygofer, irregularly stomach-like in proflile left view; right side, posterior margin producrd into a strip (Figs 29, 32). (4) Sternite VII with posterior margin forming a pit in middle 1/2 (Fig. 36).
