( Figs. 5a–f View FIGURE 5 )
Adult (in alcohol). Length of forewing 21.3 mm (n=3). Forewing narrow and long, dark brown, with many light speckles. Hind wing triangular, and semi-transparent.
Wing venation ( Figs. 5a–b View FIGURE 5 ) typical of genus, but in forewing crossveins r-m and m-cu partly transparent, distance between m-cu and cu equaling length of cu.
Male genitalia. Abdominal segment IX annular; in lateral view anterior margin slightly produced anterad and posterior margin concave at insertion of inferior appendage, ventral margin about 3.5 times as long as dorsal margin; apicolateral angle obtuse, about 1/8 as long as preanal appendage; anterior margin with shallow excision in dorsal view. Preanal appendage elongate, setose. Segment X tongue-like, sclerotized basally and membranous apically, nearly half as long as preanal appendage, in dorsal view tapering from base to apex with distal end rounded. Intermediate appendage about half as long as preanal appendage; basal half broad; distal half narrow, curved ventrad, tapering to apex and curved inward, two intermediate appendages meeting at angle of 90° in dorsal view; lateral margin with acute process curved downward in middle in lateral view. Superior arm elongate, highly sclerotized, about half as long as preanal appendage; S-shaped in lateral view and arched laterad in dorsal view; apex obtuse. Inferior appendage setose; triangular in lateral view; in ventral view sub-rectangular, about 3 times as long as wide, with apex obliquely truncate. Phallus with 12 strong spines, endothecal armature bearing many fine spines.

Diagnosis. The new species belongs to the second subgroup, as indicated by having the intermediate appendage curved mesad, and is similar to S. stoetzneri Döhler 1929 from Sichuan, China. This species can be distinguished from the latter by the male genitalia: (1) the dorsum of segment X is much broader than the distal half of the intermediate appendage (they are equal in width in S. stoetzneri ); (2) the intermediate appendage bears an acute process in the middle of the lateral margin (absent in S. stoetzneri ).
Etymology. The specific name is derived from the Latin word acanthocladus, referring to the tooth of the intermediate appendage in lateral view.
Distribution. China (Guang-xi).
