Chorsia
dinglei sp. n.
 9mm. The only specimen was noted as an aberration in the original
description of octosema but included as a syntype (see above). It
has the forewing pattern more irregular, less blocked, but with the submarginal
more prominent, a series of dark brown blocks with gaps, the blocks occurring in
three sets of two. The subapical pale spot on the underside is more obscure. The
ground of the forewing and the hindwing generally are much paler than in octosema. The male abdomen also differs considerably with the
side sections of the frame in the eighth sternite straight rather than angled
obtusely inwards, and the valve is tapering over the apical part and lacking a
ventral hook to the apical margin. The aedeagus vesica is narrow rather than
globular and has a long apical cornutus.
