Th II with 1 (a5) anterior, 0–2 median (m2, m4) and 6 posterior (P3 complex) mac. Th III with 3 mac (p2–3 complex) plus a4 mac present or absent ( Fig. 3A ). Abd I–III with 0, 1 (m3) and 1 (m3) central mac ( Fig. 3B ). Abd IV with 2 to 4 (A5, Si, B4–5) central mac ( Fig. 3C ), rarely 5 or 6. Th II–Abd V with ms and sens formula 1, 0| 1, 0, 1(0), 0, 0 and 1, 1 | 0, 1, 1, +, 2, respectively; Abd IV with 3 (T2, T4, D3p) bothriotricha ( Fig. 3 ). Male with circinate genital plate. Dens with 1 or 2 rows of dorsal spines, outer row with spine-like mac ciliate, inner row with conical spines gently ciliate ( Fig. 5E ). Mucro with main 3 to 6 teeth, proximal tooth (v2) with 1–5 denticles ( Fig. 5F ) (modified from Hüther 1962, 1983; Wilson 1982; Deharveng 1990; Deharveng & Gers 1993; Barra 2006; Soto-Adames et al. 2014; Jantarit et al. 2020; Surakhamhaeng et al. 2021)
