Remarks. This species was described based on a single specimen from Chiang Mai; nearly 150 specimens have since been examined, allowing us to discuss intraspecific variation for this interesting species. The mesosoma varies from uniform reddish (Figs 71, 72) to largely infuscated dorsally and posteriorly (Fig. 73). The metasomal setal spots vary from bright golden (Fig. 71) to pale whitish gray (Fig. 72). The shape of the posterior T2 spot varies from a nearly equilateral triangle (Fig. 72) to broadly obtuse triangle (Fig. 73). There can be a medial setal spot on T3 (Figs 72, 73) or T3 can lack such a medial spot (Fig. 71). The body length varies from 3.5 to 7.5 mm.
