Male 7.5 mm long, 2.3 mm wide across eyes and 2.9 mm wide across hind margin of pronotum. Female 7.5 mm long, 2.3 mm wide across eyes and 2.9 mm wide across hind margin of pronotum. Ratio of width of head including eyes to hind margin of pronotum 0.79.

Pale greenish brown with brown spots. Forewings and legs brown.

Male genitalia: Caudal margin of pygofer convexly rounded, without macrosetae. Subgenital plate of uniform width, upturned, and with rounded apex, several microsetae on lateral margin. Style narrow and long, apophysis curved dorsally almost at right angle, robust with rounded apex. Aedeagus with well developed bifid dorsal apodeme, preatrium absent, aedeagal shaft slightly widened apically in lateral view, apex in caudal view broadened with apical median notch.

Material examined. Holotype 3, China, Sichuan Prov., Xikang, Gonggashan, 10–12 Sep. 1939, Zhou Yao, Zheng Fengling and Du Tianhe. Paratype: 1Ƥ, data as holotype (All in NWAFU).

Figs. 1, 4, 7, 11–13, Sinojassus loberus ; Figs. 2, 5, 8, Sinojassus aspinus ; Figs. 3, 6, 9, Sinojassus compressus . 1–3, Habitus, dorsal view; 4–6, Habitus, lateral view; 7–9, face; 10, Female first gonapophysis; 11, Magnified view of apex of first gonapophysis; 12, female second gonapophysis; 13, Magnified view of apex of female second gonapophysis.

Remarks. This species resembles Sinojassus loberus externally but can be distinguished from the latter by: 1) lack of dark patches on the forewings and legs brown; 2) subgenital plate not triangular; 3) male pygofer without a ventral lobe and without macrosetae; 4) aedeagus widened near apex with a median notch; and 5) style with more robust apophysis.

Etymology. The name of the species refers to the absence of macrosetae on the male pygofer.
