( Fig. 5 View FIGURE 5 )

Nyctiophylax (Paranyctiophylax) adaequatus Wang & Yang 1997 View in CoL (in Yang et al. 1997): 284–285, 287–288, fig. 6 (male). Type locality: Henan (Song-xian Co., Mt. Bai-yun-shan N34.08°, E112.05°).

Remarks. Additional field collections and laboratory identifications have brought us more specimens of this species. These specimens from other parts of China show interesting variations, possibly with a geographical cline, especially in the shape of the inferior appendages. The holotype also is redrawn here for comparison.

In each inferior appendage of the holotype, the basomesal lobe is only slightly shorter than the dorsal branch of the main body in lateral view ( Fig. 5E View FIGURE 5 ), with a narrow apex and an obviously angled mesal protrusion in ventral view ( Fig. 5F View FIGURE 5 ). Material from Gui-zhou shows a similar pattern. However, in a specimen from Guang-dong (southern China) the basomesal lobe is obviously shorter than the dorsal branch of the main body of each inferior appendage in lateral view (5A), with a blunt tip and the mesal projection not so distinctively angled ( Fig. 5B View FIGURE 5 ). These characters are also variable individually in the same collection ( Fig. 5C View FIGURE 5 ). In specimens from Qin-ling (northern China), the basomesal lobe is slightly shorter than the dorsal branch of the main body of each inferior appendage as for the holotype, but with a more acute apex and the mesal projection is not so distinctively angled in ventral view ( Fig. 5H View FIGURE 5 ).
