CommentThys van den Audenaerde pointed out that L. polylepis was based on an aberrant L. laterale with 19 dorsal scale rows.

Distribution: Not reported from Benin according to ULLENBRUCH et al. 2010. Has been erroneously listed for Benin but has not been found there although it probably does occur there (Hughes 2013). For a map with localities in Equatorial Guinea see SÁNCHEZ-VIALAS et al. 2022.
