::The Moths of Borneo::

SUBFAMILY EUSTROTIINAE

Cretonia forficula sp. n. (Plate 3, Figs 116, 123, 126)

GG, EE 9-10mm. This is a slightly smaller and more variegated species than the next, resembling vegetus more closely. The male genitalia are distinguished by having long spines arising ventrally from the tegumen and curving down within a sheath to near the base of the valve sacculus; they resemble the cerci of some Dermaptera and together form an incomplete circle when slide‑mounted. The juxta is elongate, dividing into two dorsally, the two processes being very long and slender, extending two‑thirds of the way up the tegumen. The valve has a horn‑like saccular process as in lanka (see above), but the costal process is slightly more produced, and the cucullar apex is larger and flexed ventrally. The aedeagus vesica lacks a cornutus. The female genitalia have the ductus bursae funnel‑like, evenly sclerotised, and the corpus bursae is not particularly thickened or corrugated.
