DiagnosisDiagnosis: B. alexandri sp. nov. is easily distinguishable from the allopatric B. strauchi bedriagae by having a low number of precloacal pores (usually 3+3, more rarely 3+2 or 2+2, in a single specimen MCCI-R1678: 4+4; N = 8), widely separated by two preanal scales, while B. s. bedriagae has 10 – rarely 8 - precloacal pores arranged in a continuous row or very rarely separated by a single scale. Moreover B. alexandri has three infralabials, instead of two of B. s. bedriagae. Also B. s. strauchi has the precloacal pores widely separated, but the number is higher than in B. alexandri, since it has 4+4 precloacal pores in 18 out of 19 examined specimens.
There are no obvious morphological differences between B. alexandri and B. aporus, which differ by having more body annuli, less dorsal segments and ventral segments at midbody. 
EtymologyThe species is named in honour of A. Allan Alexander (1962-), who made the most valuable study on the Blanus strauchi complex and realized that the eastern populations could be distinguished from the Cilician taxon aporus.
