The genus Plectrocnemia Stephens in China (Trichoptera, Polycentropodidae) Author Zhong, Hua Author Yang, Lian-Fang Author Morse, John C. text Zootaxa 2012 3489 1 24 journal article 10.5281/zenodo.209646 248e2740-8f3d-4c19-af6b-8f65c440db88 1175-5326 209646 6AC261D5-E4E1-4C1C-A7E2-2918F0A308B9 Plectrocnemia yunnanensis Hwang 1957 ( Fig. 10 ) Plectrocnemia yunnanensis Hwang 1957: 383 (male); type locality: China (Yun-nan Province: Yong-ren). FIGURE 10. Plectrocnemia yunnanensis Hwang 1957 , male genitalia. A, ventral view; B, left lateral view; C, dorsal view; D, phallus, left lateral view; E, phallus, dorsal view; F, inner surface of left preanal appendage, inner view. inf.app. = inferior appendage; int.app. = intermediate appendage; m. v.pro . = mesoventral process of a preanal appendage; ph.b. = phallobase; ph.c. = phallicata; ph.scl. = phallic sclerite; pre.app. = preanal appendage; s.IX = sternum IX; t.IX = tergum IX; t.X = tergum X. The original description and illustrations are quite simple. The species is very similar to P. arphachad Malicky & Chantaramongkol 1993 ( Thailand ) , P. forcipata Schmid 1965 ( China : Yun-nan), and P. distincta Martynov 1935 ( India ) . As a matter of fact, they could actually be the same species since the drawings of these species are almost identical. We provide here more detailed descriptions and illustrations of P. yunnanensis for further comparison: Adult. Length of each male forewing 11 mm (N = 1). Head of specimen in alcohol brown with light brown antennae, pronotum light brown, meso- and metanota brown, forewings brown with white warts and stripes. Male genitalia. Mesal portion of tergum IX membranous in dorsal view ( Fig. 10 C). Tergum X membranous, long, rectangular, with 2 pairs of long, needle-like intermediate appendages in dorsal view ( Fig. 10 C), with dorsal pair much more slender than ventral ones. Preanal appendages broadly foliaceous, each with its mesoventral process composed of row of irregular teeth ( Fig. 10 F). Inferior appendages long and thick, with distal 1/3 slender and abruptly curved mesad ( Fig. 10 A). Phallus slender, tubular ( Figs. 10 D, 10E), with oval dorsal plate at end of phallobase, this plate with pair of crinkled structures when viewed dorsally ( Fig. 10 E); parameres absent.
