Male genitalia. The Chinese specimen is quite congruent with the drawings of N. (Paranyctiophylax) sagax Mey 1995 from Vietnam, the slight difference is the apicodorsal end of each preanal appendage obviously protruded in a short finger-like process and its mesoventral process with the apex more acute and curved downward in lateral view ( Fig. 6A ); a drawing of these character variation details, together with drawings of the phallus and a ventral view of the male genitalia are provided for further comparison ( Figs. 6B, 6C ).
