Benbowia kiriakoffi sp. n.

Benbowia kiriakoffi

Benbowia kiriakoffi

17-18mm, 23 mm. The forewing green ground colour is slightly bluer than in virescens; the fasciation is very similar but for the sagittate black mark on the submarginal just subcostally, which is much more pronounced than in virescens. The hindwing dorsum is generally suffused with dark brown. The main difference is in the male genitalia where the socii are set further apart, are straight, broad ended, rather than adjacent, outcurved, apically serrate; the serrate ventral processes of the valve are rounded rather than acute; the serrate margin to the eighth tergite is broadly bilobed rather than monolobed.
