Pseudoeupolyphaga Qiu & Che 2024

GenusPseudoeupolyphagaQiu & Che, 2024 Pseudoeupolyphaga Qiu & Che in Han et al. 2024: 165. Type species. Polyphaga yunnanensis Chopard, 1922, by original designation. Supplementary diagnosis. Following anatomical examination of specimens representing 15 species and subspecies, no noteworthy variations were discerned in the sclerites of female external genitalia and the shape of spermathecae across different species within this genus. Consequently, detailed descriptions of female external genitalia and spermathecae for these species were omitted, and instead, a summary diagnosis encompassing the genus is provided (Fig. 6). Comprehensive information and illustrations of the anatomical samples are available in the supplementary material (Suppl. materials 1, 2). Paratergites (pt.) banded or lamellar. Crosspiece (cp.) indistinct or distinct, with a small protuberance that points towards the posterior lobes of valvifer II (p. l.). The posterior lobes of valvifer II fuse with the anterior arch (aa.) forming a circinate structure. Posterior lobes of valvifer II well-sclerotized or not, curved apically. The first valvule (v. I) long, slightly curved, with more pronounced lateral sclerotization. Basal part of valvifer II (v. II) and valvifer III (v. III) enlarged. The spermathecal plate (sp. pl.) well-sclerotized, narrow, depressed downward in the middle. Basivalvula (bsv.) symmetrical, with two lobes narrow. Each lobe with curved anterior margins, curly lateral margins, and round posterior margins. The spermatheca (sp.) consists of a large spherical ampulla and a short spermathecal duct. With or without a curved and elongated duct attached to the ampulla. The vestibular sclerite (vst. s) shaped like the letter “ W ”, with three protrusions. The subgenital plate (SVII) densely setose, posterior margin bulging and protruding, with middle part slightly concave inward or not.
