( Figs. 1–2 )

Neoperla baotianmana Li & Wang, 2011 . Entomological News. 122: 3. Type locality: Henan Province, Neixiang County, Baotianman.

Supplementary description. The aedeagal sac is ca. 1.5X as long as the tube, the armature consists of ca. 20 pairs of large lateral spines in the median two thirds of the sac length and are arranged in S-shaped line.

Female ( Figs. 1 a–c). Forewing length 10.9-11.0 mm. Head pattern similar to male. Subgenital plate produced in a triangular tab and slightly sclerotized along posterior margin. Vagina longer than wide, somewhat ovumshaped, with a weak sclerite in base of spermathecal stalk; spermathecal stalk slender, gradually expanded to main part of spermatheca; spermatheca with brown internal spicules, apex bearing a single curved accessory gland.

Egg ( Figs. 2 a–d). Oblong oval shaped. Length ca. 0.41 mm, width ca. 0.24 mm. small globular bodies occur throughout the egg chorion. Collar not distinctly stalked, but slightly constricted at base, width ca. 0.09 mm at rim. Collar short and indistinctly flanged, surrounded by 2-3 irregular rows of heavily pitted cells. Chorion striate, each primary stria enclosed by a pair of secondary striae; striae surfaces coarse, sulci between each group of striae slightly wider than striae, intermittent with smooth and coarse floor of irregular rows of dense punctations near and between short transverse striae. Primary striae connect to collar and lid. Lid covered with distinct follicle cell impressions; follicle cell impressions densely punctate in each cell; walls of cells coarse and moderately thin.

Material examined: 1 male and 2 females ( HIST), China, Henan Province, Neixiang County, Baotianman, 2008. VIII.12, Ding Yang. 1 male, 1 female ( CAU), Henan Province, Song County, Baiyuanshan, 2008. VIII.13, Ding Yang.

Distribution. China (Henan Province) (Li and Wang 2011).

Remarks. The aedeagal sac of N. baotianmana was not extruded in the types because the large spines made the dissecting process difficult. The aedeagus of a male was fully extruded after nearly 2 hours of extraction. The uneverted aedeagus, however, is sufficient for identification at present as no similar species is known. Combined with the internal features of the female terminalia, this species clearly belongs to the clymene group as stated in Li and Wang (2011).
