Kamimuria shiae, 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

Kamimuria shiae sp. n.

( Figs. 1–2 )

Adult habitus. General color yellow brown. Head yellowish brown ( Fig. 1a ), with brown triangular ocellar patch, the patch much lower in paratype. Antennae brown, generally becoming brownish toward apex, pedical and scape darker, palpi light brown. Pronotum brown with darker rugosities, anterior margin and stripes along median suture darker. Legs yellow brown with dark knees. Wing membrane yellowish brown, veins darker.

Male ( Figs. 1–2 ). Forewing length ca. 18.5 mm. The recurved hemitergal lobes barely covering posterior margin of tergum 9; each lobe gradually narrowing medially in dorsal and lateral views, with distinct ventral spinules near apex ( Figs. 1 b–d). Tergum 9 with spinous mesal sclerite and covering over ⅔ length of tergum 9. Sensilla ba- siconica on tergum 8 indistinct, with only a few sparse pale brown sensilla basiconica ( Fig. 1b ). Metasternum and sterna 4–7 with patches of setae.

Aedeagus ( Fig. 2 ). Tubular in dorsal and ventral views and trilobed in lateral view, with membranous and bald dorsal and larger ventral lobes. Basal ½ enlarged and bald; basal ½ of distal armatures mostly with microtrichia ventrally and larger sharp spines laterally and dorsally; the spinous patch widely separated laterally and narrowly interrupted dorsally. Distal ¼ in caudal view gourd-shaped against the dorsal and ventral lobes (the dorsoapical membraneous lobe uneverted in paratype thus not gourd-shaped), with a large rounded spinous area between the lobes.

Female. Unknown.

Distribution. This species is known only from the Wuyi Mountains of Fujian Province.

Type material. Holotype male ( HIST): China: Fujian Province, Nanping City, Wuyishan , Guadun , 1200 m, 2019.VIII.25, light trap, N 27°44’12’’, E 117°38’12’’, M.Y. Li & W.H. Li; paratype, 1 male, China: Fujian Province, Shaowu County, Wuyishan , Nanhu Forest Farm , 409m, 2019.VI.11, light trap, N 27°32’38’’, E 117°29’3’’, R. R. Mo & W.H. Li.

Etymology. The specific epithet refers to Ms. Xiuhong Shi, organizer of the stonefly surveys.

Remarks. The male of the new species is similar to K. robusta in having similarly arranged spines of aedeagal sac. The aedeagus of K. shiae can be however, easily distinguished from K. robusta by a larger dorsal patch of armature and presence of a more projecting membranous ventral lobe.
