Comment(s) on data
Chaenostoma lisae (Poupin & Bouchard, 2010), described from Mayotte, is considered as a junior synonym of C. crassimanus in Shih et al. (2015, Ocypodidae of Taiwan), Teng et al. (2016, Crustacean Research). However, none of the specimens examined to establish this synonymy (Naderloo, 2013; Teng et al., 2016; Shih et al., 2015) belong to the type serie of C. lisae, most of them being instead pre-identified as 'M. boscii' and some of them used as comparative spp. for the description of C. lisae by Poupin & Bouchard (2010). Therefore, until the types of C. lisae are not carefuly revised this species should be considered as a valid dwarf species endemic to WIO (pers. note J. Poupin, September 2017).
