Gyrtothripa
parvipusilla
sp. n.
6-7mm. This is a smaller and slightly paler species than pusilla (7-9mm);
the dorsal half of the basal third of the wing is more distinctly paler, and the
general tone of the wing more rufous. The male genitalia have the tegumen
reduced relative to the vinculum compared with pusilla; the uncus is less
strongly tapered and more clearly distinguished from the tegumen. The valves are
somewhat narrower, the costal margin less produced into an angle, and the
ventral process with curved setae is rounded rather than acute. The aedeagus is
slender, broader. The female has the corpus bursae ovate rather than
sausage-shaped, with the scobination distinctly denser over two-thirds rather
than uniformly light throughout.
