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