Genus Torbda Cameron, 1902

Torbda Cameron, 1902c: 18 . Type species: Torbda geniculata Cameron, 1902 . Designated by Morley (1913).

Miophatnus Cameron, 1907b: 105 . Type species: Miophatnus nigromaculatus Cameron, 1907 . Monobasic.

In Japan, two species T. parallela Momoi, 1970 , and T. sauteri Uchida, 1932 , have been recorded. Momoi (1970) and Gupta & Gupta (1983) provided the character states for both species by descriptions and/or keys, while many additional specimens (including a Chinese specimen) of T. sauteri indicate that this species with a large intraspecific variation in the body coloration and sculptures. Table 1 shows the variation of body coloration of T. sauteri and T. parallela , the character states of Figs. 11H–J (fore wing), 11K and L (hind tibia), and 11N–P (T7) are previously used for the separation of both species and of Figs. 11E– G (occiput) are newly found in this study. The character states of Figs. 11I and 11O are intermediate condition of T. sauteri and T parallela . In addition, these characters varied individually and more or less overlapped each other and are not reflect the species concept. Thus, I conclude that both species are same species. In this study, I synonymize T. parallela under T. sauteri (syn. nov.)
