Kamimuria tenuilobata, Li & Kong & Liu, 2020

Li, Weihai, Kong, Fanbin & Liu, Siqi, 2020, New and little known species of Kamimuria (Plecoptera: Perlidae) from Fujian of China, Zootaxa 4809 (2), pp. 363-373 : 364-371

Kamimuria tenuilobata sp. n.

( Figs. 3–4 )

Adult habitus. General color brownish. Head yellowish brown, ocellar patch light brown, posterior portion around posterior ocelli brownish, two dark triangular patches present between forward of M-line and base of antennae ( Fig. 3a ). Antennae dark brown, palpi brownish. Pronotum brownish, rugosities obscure, strips along median suture dark brown, posterolateral margin expanded laterally. Legs light brown, knees slightly darker. Wing membrane pale brown with darker veins.

Male ( Figs. 3–4 ). Forewing length ca. 17.1–17.4 mm. Hemitergal lobes re-curved and nearly reaching the posterior margin of tergum 9, each lobe sharply narrowing medially in dorsal and lateral views ( Figs 3 c–d). Tergum 9 with spinous mesal sclerite covering ⅔ length of the tergum. Tergum 8 with several rows of sensilla basiconica ( Fig. 3b ). Metasternum and sterna 4–7 with patches of setae.

Aedeagus ( Fig. 4 ). Tubular in shape with a medial constriction. Basal ½ mostly membranous, with ventral surface covered by microtrichia at the narrow portion. Distal ½ trilobed with complex armatures: the largest basoventral lobe globular, with lateral and dorsal spinous area and a small ventral spinous patch connected with patches of medial lobe, which consists of three lateral rows of spines and triangular ventral patch of spines; the dorsopical lobe slightly bilobed, with two patches of larger spines in dorsal and caudal views; the caudal patches of spines seemingly as a pair of large single spine in low magnification.

Female. Unknown.

Distribution. This species is known only from the type locality, Shaowu County of Fujian Province.

Type material. Holotype male ( HIST): China: Fujian Province, Nanping City, Shaowu County, Wuyishan , Nanhu Forest Farm , 409m, 2019.VIII.10, light trap, N 27°32’38’’, E 117°29’3’’, R. R. Mo, S.Q. Liu & R. J. Liu, paratype: 1 male ( HIST): same locality and collector, 2019.VIII.11.

Etymology. The specific epithet refers to narrow apical part of the hemitergal lobe of tergum 10.

Remarks. The hemitergal lobes of tergum 10 of the new species are similar to K. similis Klapálek, 1912 from northern Vietnam, especially in lateral view (comparing fig. 48 of Sivec & Stark 2008 and Fig. 3d ). However, the large spine-like sclerites on the aedeagal armature of K. similis is absent in K. tenuilobata .
