Distribution: Pakistan, India, Myanmar, Thailand, Malay Peninsula, Singapore, Indonesia, Borneo, Vietnam, and China (Hainan).

Remarks: Austruca annulipes was thought to be widely distributed in the IWP ( Crane 1975; Naderloo et al. 2010). However, Shih et al. (2013) showed the specimens from eastern Africa represent a different species (as “ Uca aff. annulipes ”), later described as Uca occidentalis Naderloo, Schubart & Shih, 2016 ( Naderloo et al. 2016). COI sequences show minimal genetic divergence suggesting good connectivity across the remainder of the species’ range from Pakistan to China ( Fig. 4 ). Saher et al. (2014) noted that A. iranica and A. annulipes are sympatric in Pakistan, confirmed with COI data here.
