Dipterygina major sp. n
Dypterygia indica Moore sensu Holloway, 1976: 9.

Dipterygina major

22-23mm. This is much larger than the other two species and somewhat larger than indica Moore. The forewings are generally much darker, with the dorsal markings distinct, whitened, the main 'step' perpendicular to the dorsum. In the male genitalia the valve is somewhat broader, the apical
finger-like process shorter and broader than in indica. The vesica of the aedeagus is broader but the group of spines is distal as in indica. The ventral part of the triangular juxta is diagnostically strongly excavate. An externally similar species flies in Sulawesi (slide 14063) but this differs in male genitalia (juxta not excavate; spiny zone of vesica more extensive and more basal).
