Male genitalia. Inferior appendages two-segmented ( Fig. 236 View Figs ). In lateral view, phallus bent, with curved elongated apex ( Fig. 238 View Figs ), with broad opening in dorsal view ( Fig. 239 View Figs ). In dorsal view, segment X widely separated medially ( Fig. 237 View Figs ).

Material examined. Thailand: 3 males, Lamphun Province, Mae Ping, coll. A. Nuntakwang, 22 April 2003 (HMPC) .

Distribution. India, Laos, Thailand, Vietnam.

Remarks. Fore- and hind wing images were not provided because the observed specimens were old, and the wing pattern was no longer clear. Therefore, forewing drawing ( Fig. 235 View Figs ) is provided to show the difference of the wing pattern to other Pseudoleptonema species. No female specimens were available for examination.
