12. Sorolopha plinthograpta (Meyrick, 1931)

Sorolopha plinthograpta Meyrick, 1931: 135 (Ƥ, China: Formosa).

Olethreutes plinthograpta: Clarke, 1958: 539, plate 268, figure 1-1a (wings, Ƥ genit.) Eudemis plinthograpta: Issiki, in Esaki et al., 1957: 69, figure 332.

Sorolopha plinthograpta: Diakonoff, 1973: 84, figures 131–133 (3, Ƥ genit.).

Diagnosis. This species is similar to S. autoberylla (Meyrick, 1932) and S. plumboviridis Diakonoff, 1973 in male genitalia, but it can be separated from those two by the socii, which in S. plinthograpta have only simple hairs and lack apical bristles; the sacculus having a smaller spine cluster on the angulation; and the cucullus bearing very long bristles beneath the ventral prominence. S. plumboviridis has short spines along the ventral margin of the cucullus that extend to the sacculus. S. plinthograpta also resembles S. khaoyaiensis Kawabe, 1989 in male genitalia, but it can be distinguished from the latter by external characters.
