Wing length 4 mm; width 1.7 mm; vein R 2+3 is short, about half the length of R 2; vein Sc apex at about one-third length of R 2+3; vein R 2 is long, about twice as long as R 4+5 Coramus gen. nov. differs from Dacochile in the length of vein Sc, which in the latter ends at one-third length of Rs and in proportion of Rs to R 2+3. Coramus gen. nov. differs from Nannotanyderus in having a long vein R 2, about twice as long as R 2+3. Male genitalia with gonopods elongate; gonocoxite
