b) Original description and taxonomic history
...
. Massin et al. (2009) mentioned that theHolothuria (Metriatyla) scabravar.versicolorcan hybridize with theHolothuria (Metriatyla) scabra; however, they stood their ground for splitting using differences found in molecular studies, skeletal elements and external morphologies. Such a species delimitation concept veers away from biological species concepts which require reproductive isolation; the species delimitation concept used here seems to draw similarity with the phylogenetic species concept by Wheeler and Platnick (2000) instead, which focuses on describing species through their unique combination of fixed character states.
