Genus Indochinamon Yeo & Ng, 2007

Type species.

Potamon villosum Yeo & Ng, 1998, by original designation.

Remarks.

The genus currently contains 38 species from Thailand, Vietnam, Laos, Myanmar, India and China (Table 1, updated from Ng et al. 2008; Naruse et al. 2018). Established by Yeo and Ng (2007) for Indochinese species previously placed in Potamon Savigny, 1816, s. lato, Indochinamon is defined by a suite of characters: carapace low with a relatively flat dorsal surface; the epigastric cristae are separated from the postorbital cristae by a distinct groove; the postorbital cristae is not confluent with the epibranchial tooth; the exopod of the third maxilliped has a long flagellum; the ambulatory legs are relatively short and stout; the male pleon is narrowly triangular; the sternopleonal cavity reaches an imaginary line joining the median parts of the coxae of the chelipeds; and the G1 terminal segment is relatively short, with the groove for the G2 marginal in position, and the dorsal flap is either absent or only low and broad.
