Sphingonaepiopsis pumilio
Diagnostic description:
Body and forewing much more brown than either Sphingonaepiopsis gorgoniades or Sphingonaepiopsis kuldjaensis. Abdomen upperside without three pairs of white lateral spots (unlike Sphingonaepiopsis gorgoniades). Hindwing upperside orange-yellow, with brown marginal band of nearly even width, not tapering as in Sphingonaepiopsis kuldjaensis.
Male genitalia: Uncus compressed, sharply pointed. Gnathos pointed. Valve strongly narrowed in apical half, almost pointed, longitudinally grooved along the dorsal edge. Harpe broad, densely covered distally with long spines that lie flat upon the harpe except for a few at the apex. Phallus without armature, or with a short, transverse, subapical ridge, bent proximad.
