description: Sinopoda longiducta sp. nov.
(Figs 33–48)
Type material: Holotype: ♂, CHINA: Sichuan Province: Baoxing County, Fengtongzhai Natural Reserve, 30°25′N, 102°50′E, 970 m, evergreen broad-leaf forest, 29 June 2012, M.X. Liu (MHBU, SP-SC-12-0601).
FGURES 33–34. Sinopoda longiducta sp. nov. 33–34 habitus ofmale holotype (33 dorsal, 34 ventral). Scale bar: 33–34: 2 mm.
Paratypes: 6♂♂, 3♀♀, same data as holotype (1 female in MHBU, SP-SC-12-0602, 6 males and 2 females in SWUC, SP-SC-12-0603–0610).
Etymology. The specific name is derived from the Latin word ‘ longi -’, meaning ‘long’, and the Latin word ‘ducta’, meaning ‘duct’, referring to the long internal duct system; adjective.
Diagnosis. Males of Sinopoda longiducta sp. nov. can be distinguished from other Sinopoda species (except S. triangula and S. globosa sp. nov.) by the triangular projection at the subdistal embolus (Figs 35–37, 42–45). The males of the new species differ from S. triangula and S. globosa sp. nov. by: the long distal embolus (longer than embolic apophysis) and the slender distal part of embolic apophysis. Females can be distinguished from other Sinopoda species by the long glandular appendage of vulva and its globose apical swelling (Figs 40–41, 46–48).

Palp (Figs 35–37, 42–45). Conductor slender and long; embolus slightly curving and arising from tegulum in 7 to 8-o'clock-position (left palp in ventral view), subdistal embolus with a triangular projection, embolic tip extending slightly beyond embolic apophysis, basal part of embolus only partly visible in ventral view; sperm duct slightly curved in ventral view; dRTA slender and straight, with rounded tip, vRTA short and stout from retrolateral view; both cymbium and tibia elongated, cymbium slightly longer than tibia.
