Kamimuria simplex

Kamimuria simplex (Chu, 1929) (Figs. 2–3) Perla simplex Chu, 1929: 88; Claassen, 1940: 145. Kamimuria simplex: Wu, 1938: 200; Illies, 1966: 294; Du et al, 1999: 61; Zwick, 1977: 116; Sivec & Stark, 2008: 137; Stark & Sivec, 2013: 117; Huo et al., 2022: 274. Amended description of aedeagus (Figs. 3d–3f). Aedeagus membranous, medially with a constriction in dorsal and ventral aspects, posterior to the constriction is a global bald membrane which extends dorsally in a tubular apex (Fig. 3f); sac is membranous, lacking any sclerites, mostly covered with dense minute spines or wrinkles but the apex with dorsal, ventral and lateral armatures of larger spines (Figs. 3d, 3e); the dorsal and lateral spines forming a C-shaped band, distal of the band is a small projecting membranous lobe forming the extreme of the sac (Fig. 4f). Female. Only known from the original description and illustration of type series. Egg and larva. Unknown. Examined material. Neotype, 1 male (IZCAS), China: Zhejiang Province, Hangzhou City, Hushan park, ca. 30.36 N, 120.20 E, 859m, 1957.VI.30, leg. unknown. Addtional material: 1 male (IZCAS), China: Fujian Province, Wuyishan, Jiuqu stream, 750m, 27.6404 N, 117.9348 E, 1990.V.30, leg. Morse et al. Distribution. Southeastern China (Fujian, Zhejiang provinces). Remarks. The neotype male was collected in Hushan Park, about twenty km to the Middle Tien-tsu Temple, the holotype locality in Hangzhou City at summer, around the date of holotype (July 7, 1928). We also present new illustrations of head, tergal characters (Figs. 3a–3c) for an easier identication of this species. These two males (Figs. 2a, 2b) are identical with the types in “dark habitus, lighter pigmentation of costal margins of wings, and spineless tergum 8, especially the leg coloration: proximal portion of femur and sometimes the middle portion of tibia yellowish, the rest of leg being black” in the original description of Chu (1929). Kamimuria simplex was recently redescribed by Huo et al. (2022) based on recently collected adults of both genders from Fujian Province, but those specimens of have evenly dark legs and sensilla basiconica patches present on posterior tergum 8, which are different from the type series. Huo’s specimens may refer to K. circumspina which is also distributed in Fujian.
