Risoba martinii sp. n.
Risoba literata Moore sensu Martini & Thöny, 1993: 7.


Risoba martinii (paratype)

18mm. The facies is generally similar to that of
basalis Moore (see below) in the rather dull green forewings with an oblique, pale subbasal band and a more irregular and indistinct postmedial; the apical spot is dark brown but has a much narrower basal sector than basalis. The subbasal and postmedial meet the dorsum further apart than in basalis, the postmedial being more sinuous, less angled. The paler basal part of the hindwing is clouded with brown as in some other species of the jucunda group but not in basalis. The male genitalia are typical of the jucunda group with a strong crimp to the costal flange. The aedeagus and vesica are ornamented similarly to those of calainigrata, but the aedeagus spines are slightly longer.

Holotype . BRUNEI: 80m, Ulu Belait, lowland forest, 21.2.1980 (Lt. Col. M.G. Allen), BM noctuid slide 16681.

Paratype . BRUNEI: 30-60m, Labi, lowland forest and secondary, 23.7.1979 (Lt. Col. M.G. Allen).

Geographical range. Borneo.

Habitat preference. Martini & Thöny recorded a singleton from 950m on G. Trus Madi, Sabah, much higher than the lowland forest localities in Brunei of the type material.
