Nola canioralis
(holotype)


Diagnosis and taxonomic note.
The forewing of this and the next species is crossed by a series of fine, entire, but slightly irregular fasciae running transversely. At least the base, and often most of the pale areas of the wing are invested with opalescent scales. The species belong to a complex for which the name Pisara may be applicable at a subgeneric level; the complex is perhaps more diverse in the Australasian tropics. The male genitalia, including the aedeagus, tend to be rather broad, and the uncus is present but vestigial. The harpe is robust and is usually diagnostic. In canioralis the forewing submarginal is rather diffuse and zig-zag. The postmedial is stepped around the discal spot, displaced basad posterior to it, and the antemedial is transverse, sometimes delineated darker and concave basad, with the medial zone between a slightly darker grey. Opalescence is only weakly evident. The male genitalia (Sulawesi specimen; no Bornean males were located) have a rather rectangular harpe with its apical side slightly oblique. See also the next species. The female genitalia have the ductus bursae short relative to that of the next species, with the basal zone weakly sclerotised, more so on one side than the other. The two invaginate, spine-like signa are less strongly sclerotised, their bases less prominent.

Geographical range. Borneo, Sulawesi.

Habitat preference. The holotype female was taken by A.R Wallace in Sarawak, most probably in the lowlands. Three further females (in ZM, Univ. Amsterdam) were taken at 300m on Tawau Hill and at 950m and 1000m at Sayap, north of G. Kinabalu, all in Sabah.
