Parasynegia sundastriaria sp. n.
18-20mm. This species, along with the type species and diffusaria, has
the discal spots large, that of the forewing pale-centred. The dark ring to the
pale centre is variable thick, diffuse, as in diffusaria, rather than
narrow, fine as in pluristriaria where the pale centre is larger and more
elliptical. The fasciae are finer and more clearly etched than in diffusaria though
not as regular and linear as in pluristriaria.
The male genitalia are distinguished by: the broad, triangular, basal
process to the valve (digitate in pluristriaria, very small in diffusaria);
the large spatulate distal process (asymmetrically double in pluristriaria,
digitate in diffusaria); the large, straight apical spine to the
aedeagus (broader, shorter with a second smaller one opposite in diffusaria).
