Nola jarvisi sp. n.


Nola jarvisi (holotype)

8mm, 7-9mm. The forewings have a pale, slightly creamy grey ground colour, marked and suffused with blackish grey, more so in the medial zone and at the margin. The medial zone is bounded by a fine, curved antemedial, concave basad, and a strongly (but rather angularly) sinuous postmedial, concave basad anteriorly and distad posteriorly. There are raised scales medially at the costa, subcostally near the antemedial and, at the same distance from the costa, subbasally. The positions of these are similar to those in
mesosticta and helpsi, but the sinuous course of the postmedial is diagnostic. The hindwings are grey. The male antennae are finely bipectinate. The male abdomen has the apodemes of the eighth segment well developed, those of the tergite short spines at the corners of an elongate triangle. The valves are deeply cleft, the arms similar, but the ventral one slightly shorter and with a subapical spine. The harpe is small and relatively basal. The aedeagus vesica has a small, hooked cornutus and a short diverticulum scattered with small, rather granular spines along one side.
