Bioacoustics of Poecilimon parazonatus

Description. Holotype , male. Head. Fastigium of vertex equal or slightly wider than half of the scapus. Thorax. The pronotum short, slightly constricted in the middle, median sulcus located after the middle, cylindrical in prozona and distinctly raised in metazona, caudal margin of the disc concave, medial carina occurs as a yellowish line or absent, disk bordered by large light lines divergent in anterior and posterior margins constituting roughly as “) (“ shape; paranotal margin almost straight along prozona and oblique along metazona. Tegmina short, extend beyond the posterior margin of pronotum, stridulatory vein hardly visible under the pronotum; the stridulatory file with 58 teeth. Male terminalia. Cercus cylindrical, gradually tapering toward apex, the curvature is more prominent apically, incurved roughly as L-shaped, with a robust, but slightly tapered apex and 2–3 hardly distinguishable denticles apically. The subgenital plate is as long as wide or slightly wider than long, distal margin is almost truncated.

Remarks. The geographic section bordered by the two main branches of Euphrates, namely Murat and Karasu rivers, is an isolated section especially for the species preferring high-altitude habitats ( Uluar et al. 2021 ). Previously Sevgili et al. (2018) identified samples from some localities belonging to this geographic section (from Tunceli and Erzincan Provinces of Turkey ) as P. zonatus . However, none of these was from Pülümür Valley, the type locality of P. parazonatus sp. nov. The reports by Sevgili et al. (2018) from this geographic section possibly refer to the new species, yet they require confirmation by genetic data, as phenotype is not reliable enough for identification (see Discussion section below). Studying songs may provide further diagnostic characteristics.
