Description of the female Chinese specimens
Female (Figs 11–13). Forewing length 12.0–12.5 mm, hindwing length 10.0–10.5 mm (n = 4). General color yellow to brown. Head nearly as wide as pronotum, with a subtriangular dark brown area covering ocelli; compound eyes dark and antennae pale brown. Pronotum disc yellow with pale brown rugosities. Wing membrane subhyaline, veins pale brown; legs yellow without darker markings. Cerci pale brown (Fig. 11). Subgenital plate of sternum 8 forming a small rounded sclerite with a posteromedial notch (Fig. 12). Vagina oval, lined densely around base of spermathecal stalk. Spermathecal stalk and spermatheca short, slender and curled at tip; a single accessory gland occurs near spermatheca tip (Fig. 13).
China (Guangdong Province: Conghua County, Liuxi River; Shixing County, Chebaling Nature Reserve. Guangxi Province: Jinxiu suburb; Tianlin County, Pinglang). Vietnam (Di Linh, Dak Song, Gia Lai, Nghe An, Pleiku). Thailand (Chanthaburia).
This species is expected to be widespread in southern Asia. The male of Neoperla mnong has been described from Vietnam by Stark (1987) and well-illustrated by Stark and Sivec (2008) from Vietnamese material. This species has been previously recorded from China by Du (1998) and Li et al. (2012b). Females of Neoperla mnong from Vietnam were described as Javanita costalis by Navás (1932) and later described by Stark and Sivec (2008). In this study, females collected from Guangdong Province of China in 2009 are described and illustrated for the first time. The subgenital plate of these specimens is smaller and pigment patch over the ocelli is larger (for comparison see Figs 40, 43 in Stark and Sivec 2008).
