Arctornis virgamicruncus sp. n.  


Arctornis virgamicruncus (paratype)


14, 15mm. The facies is similar to that of clavimicruncus, but the male genitalia are distinct. The uncus is similar in character, but the valves have the distal margin rounded, the ventral and dorsal margins more or less parallel. The harpe is more or less straight, extending to just beyond the valve. It is apically acute, very sparsely scobinate, but only very slightly expanded along its length.

Taxonomic note. Closely related species occur in Sulawesi (slide 2213) and Seram (slides, 1985, 1994).
