All crosslines present, well marked; terminal line on both wings prominently indicated by black interveinal spots. Underside unicolorously grey, without pattern. Colour of abdomen basally and apically grey, medially dark grey. Male genitalia (Fig. 16). Uncus relatively short, stout, slightly curved; membranous part of valva broadest 2 / 3 from base, there smoothly rounded; sacculus curved ventrally, almost equally broad throughout, rounded apically; clasper fused to sacculus, ampulla lacking. Aedeagus relatively short and broad; vesica with a spined, broad, sclerotised patch with many small, thin cornuti. Female genitalia (Figs. 24, 29).
