Physotopoda thai Lelej 1995b: 15  , ♀; 2005: 51; Okayasu et al. 2018: 308.

Diagnosis. FEMALE. This species can be recognized by its T2 pattern, which has one basomedial spot, one apicomedial spot, and two apicolateral spots. Other useful diagnostic features include: the clypeus has a basomedial tooth; the vertex has a transverse patch of silver to golden setae; the mesosoma is longer than wide; the scutellar scale is posteriorly rounded and surrounded by scattered tubercles; and the pygidium is smooth. Body length 3.5–7.5 mm. MALE. Unknown.

Distribution. Laos *, Myanmar *, Thailand (Chiang Mai, Krabi, Loei, Nakhon Ratchasima, Nakhon Si Thammarat, Phatthalung, Phetchabun, Phetchaburi, Sakhon Nakhon, Songkhla, Surat Thani, Ubon Ratchathani).

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, 72View FIGURES 68–76) to largely infuscated dorsally and posteriorly ( Fig. 73View FIGURES 68–76). The metasomal setal spots vary from bright golden ( Fig. 71View FIGURES 68–76) to pale whitish gray ( Fig. 72View FIGURES 68–76). The shape of the posterior T2 spot varies from a nearly equilateral triangle ( Fig. 72View FIGURES 68–76) to broadly obtuse triangle ( Fig. 73View FIGURES 68–76). There can be a medial setal spot on T3 ( Figs 72, 73View FIGURES 68–76) or T3 can lack such a medial spot ( Fig. 71View FIGURES 68–76). The body length varies from 3.5 to 7.5 mm.
