Spaniocentra apatelloides sp. n.  
Spaniocentra apatella West sensu Holloway, 1976: 61.

Spaniocentra apatelloides

Spaniocentra apatelloides

15-17mm, 16-18mm. In facies this species resembles S. apatella West (Philippines, Sulawesi) and S. undiferata Walker (Sulawesi), but has distinctive male genitalia. In the related species there is a single, simple saccular spine, very
short in apatella. In apatelloides this is moderate but less tapering, rugose, apically blunt, with a second spine twice as long, tapering, running alongside, arising subcostally near the base of the valve. The broad aedeagus has a massive patch of cornuti in the vesica. There are two such patches in the aedeagus of undiferata but in apatella the aedeagus is narrow, the cornuti much smaller, shorter.
