Risoba viridangulata sp. n.
Risoba chlora Hampson sensu Martini & Thöny, 1993: 7.


Risoba viridangulata

17-18mm. The forewing facies places this species with glauca and allies but the pale and green marked areas of the wing are more distinctly interrupted by broad bands of grey: an arcuate one, concave costad, basal to the postmedial; a transverse one between the postmedial and the submarginal that stops short of both costa and dorsum. The male genitalia have a valve costal process as in glauca but distinctly smaller. The aedeagus has an extended row of short, well spaced spines ventrally, and the aedeagus vesica is globular with a transverse row of somewhat sinuous spines that grade in robustness from one end to the other.
