Camponotus parvus

Identification
Comparison of the features of the Camponotus wing imprints described to date is unproductive. First, the majority of the 28 fossil species (i.e., without the three imprints withdrawn from Camponotus in this paper) are described from females. Taking into account the pronounced sexual dimorphism in the size of sexual individuals in this genus, it is difficult to compare even the sizes of males and females from different localities. Since the wing length of the male C. parvus is 6 mm, it can be assumed that the size of females of this species may be 8–16 mm. Second, the standards of description and drawings of the majority of species described at the beginning of the last century do not allow comparison of the details of venation that are important for taxonomic purposes. Given these facts, our comparison shows that, among the known fossil representatives of Camponotus, there are three species with a relatively long 3r cell (Ir ca. 0.6): Camponotus curviansatus (female, FWL = 10 mm), Camponotus longus (female, FWL = 11.8 mm), and Camponotus gracilis (male, FWL = 10.4 mm). However, the latter is much larger than C. parvus. The synonymy of C. parvus with one of the two females of these two species cannot be ruled out without additional examination of the specimens.

In the study of the wings of extant representatives of Formicinae, it was shown that males have relatively wider wings than females of this subfamily, regardless of the absolute size of individuals (Perfilieva, 2007, 2021). From these data, I assume that the wing imprint of C. parvus belongs to a male.
