( Figures 62–64 )

Symplanella recurvata Yang & Chen, 2014: 21 ; Chen, Zhang & Chang, 2014: 179.

Supplementary description. Measurements. Body length including forewing: female 6.15–6.25 mm (N = 12); forewing length: female 5.30–5.40 mm (N = 12).

Female genitalia. Anal segment in dorsal view with length 1.4 times longer in middle line than widest part, apical margins arc convex; anal pore located apical margins; in lateral view small. Abdominal sternite VII in ventral view with width 1.3 times as long as length, posterior margin sinuated, behind the posterior margin with a small process. Gonapophysis VIII elongate, with eight spines at apical margin. Gonapophysis IX with two symmetrical lobes, each lobe with many spines at dorsal margin. Gonoplac with outer surface shagreen; in lateral view with base half broad, apical half narrowed.

Host plant. Bamboo ( Neosinocalamus sp. ).

Distribution. South China (Guangdong and Guangxi Provinces).

Material examined. 7♂♂ 12♀♀, China: Guangdong, Guangzhou, Huanan Botanical Garden (23°08’N, 113°14’E), on bamboo ( Neosinocalamus sp. ), 2006-IX-22, Xiang-Sheng Chen ; 5 ♂♂ 11 ♀♀, Guangxi, Daxin, Encheng , 2009-V-4, Hong-Rong Li .

Remarks. S. recurvata Yang & Chen, 2014 is closely related to S. unipuncta Zhang & Wang, 2009 but differs in: 1) anal segment in lateral view with one stout process at apical margin ventrally, which curves cephalad apically (with one tooth-like process at middle of ventral margin in S. unipuncta ); 2) posterior margin of pygofer without process (with one process in S. unipuncta ); 3) aedeagus without process at base (with two long stout processes basally and ventrally, which as long as aedeagal shaft in S. unipuncta ).
