Camptomyia heterobia Mamaev, 1961

Fig. 10

A Camptomyia male studied here matches that of C. heterobia as illustrated by Spungis (1989: fig. 3.7), with the exception of the gonostylar apex that in the present specimen is pointed (Fig. 10A) rather than narrowly rounded. What seems to be a difference in shape is most likely just a matter of how the gonostylus is oriented in the slide mount. Also, in Spungis’s illustration the ventral parameres diverge to form a V-shape, while they are parallel to each other in the specimen studied here (Fig. 10B); this difference I deem an indication of these structuresʼ mobility. The few published records of C. heterobia suggest this species to be widespread in the Palearctic, albeit rarely encountered in nature.

Revised diagnosis

Morphology

Camptomyia heterobia is characterized by the construction of the parameres, of which the dorsal pair is long and thick, with the apices bent laterad (↓ 1, Fig. 10B), whereas the much smaller ventral pair forms two pointed rods laterally attached to the aedeagal apodeme (↓ 2, Fig. 10B). Males are large, the body length being 3.3 mm in the German specimen and 4.1 mm in the Russian specimens described by Mamaev (1961), and the posterior fork (M 4 +CuA) is unusually distinct (Mamaev 1961: fig. 1.1, veins in question labeled Cu 1 and Cu 2).
