NOTE. These specimens are very similar to each other and to the original description (Ingrisch, 1995). The males and females from Malay Peninsula are almost identical to the types of this species (from Thailand) in the body coloration (including that of the hind femur proximal half, which is almost completely light brown in male and with a dark longitudinal outer stripe in female) and in the presence of a very short but distinct additional tubercle on the basal part of the male cercus ( Fig.

17); however, the male from Malaysia has the left tegmen with a somewhat wider membranous area between its mirror and lateral field as well as with a shorter and wider apical area ( Fig. 83 ). All the males from Sumatra have the left tegmen almost as in my Thailandian male ( Figs 82 and 84 ), but their cercus is with the abovementioned additional tubercle almost indistinct ( Fig. 18 ), and the hind femur of my

Sumatran female is without any dark stripe on its proximal half. These differences allow me to propose that my specimens may belong to two or three subspecies;

however, I have only one male from each of the localities in Malay Peninsula and one female from Sumatra, i.e. this material is insufficient for such decision .
