Diagnosis. FEMALE. This species can be recognized by the following characters: the femora are orange basally, the scutellar scale is posteriorly rounded and ~3–5 punctures wide, the T1 fringe is predominantly pale golden, the felt line on T2 is simple, the T2 apex lacks a pale setal band, T3 and T4 each have a medially interrupted band of pale golden setae, and the pygidium is narrow with irregular striae basally and smooth in the apical half. Body length 5.5–10 mm. MALE. See Mickel (1933a).

Distribution. China (Anhui, Fujian, Guangdong, Hainan, Hong Kong), Laos * (Attapeu, Bolikhamsay), Malaysia (Selangor), Thailand * (Chaiyaphum, Chiang Mai, Kanchanaburi, Krabi, Loei, Mae Hong Son, Phatthalung, Phetchabun, Surat Thani, Trang).

Remarks. This common species broadly overlaps with T. wilsoni in distribution in Thailand. The females can be separated by the pygidium and T1 fringe. The pygidial difference is significant, but difficult to quantify, while the T1 fringe color is easy to describe, but becomes less functional in old or damaged specimens. The males of these species are both known, but will be described in an upcoming paper. They differ in metasomal coloration and structure of the penis valves.

Trogaspidia pagdeni is currently subdivided into two subspecies (Mickel 1933a), T. pagdeni pagdeni was described from peninsular Malaysia and T. pagdeni nodoa (Mickel, 1933) from China. The only differences that Mickel noted were the shade of setal markings in females. The discovery of this species in Thailand bridges the distribution gap between these forms and provides justification to synonymize these subspecies here.
