CommentDistribution: not listed explicitly by BROADLEY et al. (2003) for Zambia. Not reported from Benin according to ULLENBRUCH et al. 2010. Not listed for Togo by Segniagbeto et al. 2012.

Similar species: P. acutus and togoensis have been confused and thus reports of one of them may represent the other. Broadley 1971, separated Psammophylax acutus (Günther, 1888) from Psammophylax togoensis (Matschie, 1893) both on the basis of constant morphological characters, such as the presence of ventrolateral stripes, and of their geographical distribution. This was followed by SEGNIAGBETO et al. 2012. 
EtymologyNamed after Latin “acuere” = sharp, or “acutus” = sharpened, pointed, or “acumen” = tip, or “acus” = needle.
