Neopanorpa brevivalvae Chou & Wang in Chou et al., 1988: 38 , fig. 9 (type locality: Rucheng, Hunan, China), syn. nov.

Diagnosis

This species can be recognized by the combination of the following features: 1) forewing with an additional short band between apical and pterostigmal bands ( Fig. 6 A–B); in males, 2) notal organ strongly arched dorsad at middle ( Fig. 6D ); 3) postnotal organ strongly raised and finger-like ( Fig. 6D ); 4) hypovalves distinctly reduced, shorter than one-fourth of hypandrium ( Fig. 6 E–F); 5) ventral aedeagal valves whitish with a pair of lateral hooks ( Fig. 6F, H ); and in females, 6) medigynium with broadly spatulate posterior arms, and a concealed axis ( Fig. 6L ).

Description

MEASUREMENTS. Male: FL = 13.5–14.8 mm, FW = 3.0– 3.4 mm; HL = 12.0– 13.2 mm, HW = 2.8–3.2 mm.; Female: FL = 13.8–15.2 mm, FW = 3.0– 3.4 mm; HL = 12.5–13.6 mm, HW = 2.9–3.2 mm.

Distribution

China: southern Hunan and northern Guangdong.

Comments

The specimens collected from the type locality (Longdoufeng) were at first determined as N. brevivalvae based exclusively on the male genitalia, especially the greatly reduced hypovalves ( Fig. 6F ). The females, however, basically conform to the holotype of N. lungtaushana in morphology, especially in the broadly spatulate posterior arms in the medigynium ( Fig. 6L ).

Neopanorpa brevivalvae was described based on a male holotype, a female allotype, as well as one male paratype and one female paratype. According to the original descriptions and illustrations ( Chou et al. 1988), the female medigynium bears an elongate axis extending beyond the main plate basally. However, the axes are greatly reduced in all the female specimens in this study. We reexamined the two female types of N. brevivalvae , and consider that they were mismatched with the males by Chou et al. (1988). Therefore, N. brevivalvae is here treated as a junior synonym of N. lungtaushana .
