Proarna bergi ( Distant, 1892a) new record

Tympanoterpes bergi Distant 1892a: 61 . ( Argentina)

REMARKS. Historically there has been confusion in differentiating the taxa P. bergi and P. bufo Distant, 1905d due to the slight differences in the morphology of the two species. Sanborn & Heath (2014) determined a geographical separation between the species with P. bufo distributed in central and eastern Argentina while P. bergi was distributed in the northern and western parts of the country. This along with differences in morphology noted by Jacobi (1907) was used to clarify the Bolivian specimens cited by Distant (1905d) and Jacobi (1907) as P. bergi rather than P. bufo ( Sanborn 2019b) .

This is the only Peruvian species of Proarna that is unicolorous dark brown with an abdomen that slightly expands laterally from the base to segment 5 before curving to the terminus. No other Peruvian species exhibits this coloration or abdominal shape.

DISTRIBUTION. The species has been reported previously from Argentina ( Metcalf 1963a; Duffels & van der Laan 1985; Sanborn 2013; Sanborn & Heath 2014) with recent records expanding the distribution to include Bolivia ( Sanborn 2019b). Previous references to Colombia were shown to be erroneous ( Sanborn & Heath 2014). It is associated with grasses in various habitats and is endothermic ( Sanborn et al. 1995a).
