Cnemidophyllum (Peucestoides) bituberculatum Gorochov 2025, sp. nov.

Cnemidophyllum (Peucestoides) bituberculatum Gorochov sp. nov. (Figs 103, 112, 113, 122–125, 134–136) Etymology. This name consists of the Latin prefix “bi-“ (two) and word “tuberculatus” (with tubercle, with tubercles) due to the presence of a pair of distinct tubercles on the last male tergite. Material. Holotype – male, PERU: Ucayali Department, “Atalaya Distr., Pitza”, 10 º 54.780' S, 73 º 51.054' W, February 2021, possibly V. Izerskyy (ZIN). Description. Male (holotype). General appearance similar to that of C. (P.) stridulans but with light brown coloration (probable result of poor preservation during drying, and lifetime coloration possibly greenish like that of C. stridulans). Preabdominal structure of body with some characteristic features: rostral tubercles more or less similar to those of C. (Peucestophyllum) granti but with upper tubercle having distal part slightly wider than scape, and with dorsal surface of rest of this tubercle having thin but distinct zigzag-like groove; pronotum with very concave anterior and slightly convex posterior edges of disc, with high dorsolateral keels having 12–13 rather large but apically rounded denticles, and with high lateral lobes having ventral edges very oblique and long as well as slightly concave (Figs 112, 113); tegmina as in C. (Peucestoides) stridulans in shape and venation (Fig. 122) but with stridulatory apparatus as in Figs 123–125 (stridulatory vein of left tegmen about 10 mm in length and with nearby 240 ventral teeth); hind wings shortly protruding beyond tegminal apices; legs with fore tibia having dorsal outer spinule near slite-like tympana, and with middle tibia (Fig. 103) distinguished from that of C. (P.) stridulans by practically uniform coloration (hind legs missing). Abdomen with following characters: last tergite with a pair of large posterior tubercles located in median part of this tergite, with rather deep longitudinal groove between bases of these tubercles, and with a pair of additional posterior lobules around previous tubercles (these lobules almost as long as these tubercles, barely hooked and with acute apices directed backwards and slightly medially; Figs 134, 135); genital plate somewhat longer than cerci and slightly narrowing to distinctly but not deeply notched apex (this notch almost angular, and styli around it very small; Fig. 136); other structures of abdominal apex as in Figs 134, 135. Female unknown. Length in mm. Body 46; body with wings 87; pronotum 13; tegmina 74. Comparison. The new species differs from C. (P.) stridulans by a longer stridulatory vein of the left tegmen with less numerous ventral teeth (this vein is almost 10 mm in length instead 8.5 mm, and with nearby 240 teeth instead about 260 ones), a distinctly deeper notch between posterior medial tubercles of the male last tergite as well as larger and barely hooked (not simply angular) lobules of this tergite around the previous tubercles (compare Figs 135 and 137), and the presence of very small styli on the male genital plate (vs: these styli are absent).
