Diagnosis.

The male of C. seminsula can be recognised externally by the oval, elongated hyaline satellite between RS4-M1 (Figs 13, 22). The ratio of length to width of the satellite is at least 2:1. The adults are the smallest of the genus Carriola . The length of the male forewings is 9.5-15.5 mm, that of the female forewings 11.5-16.5 mm. The male genitalia (Fig. 31) are characterised by a comparatively short, rectangular valva, which tapers slightly from the base to the rounded and serrated apex. The width of the basal part of the valva is in a ratio of 1:2.5 to the length. The female genitalia differ from those of related species in the size of the signum, which is about two thirds the size of the bursa and forms a distinct V-shape. The lateral lobes of the signum are gently curved outwards and have a constant width. In the centre, the signum is twice as thick as the width of the lobes (Fig. 40).

Biology.

Unknown. The flight period is from March to December. The species occurs at elevations ranging from 170 to 1600 m.a.s.l.
