| Diagnosis | Diagnosis: “A species of the genus Philothamnus characterized by an entire cloacal scale, 15 rows of scales halfway up the body, the ventrals weakly keeled number from 152 to 157 in males and from 155 to 162 in females, the undertail coverts smooth on the number from 88 to 98 in males and from 79 to 90 in females, 9 (4,5,6) supralabial, usually 2 anterior temporals (rarely only one) and two posterior temporals, from 31 to 36 maxillary teeth and an olive-brown dorsal coloration with bluish dots and blackish crossbars in front of body. Philothamnus mayombensis sp. Nov differs from all other species of the genus Philothamnus by the combination of 15 rows of midbody dorsals and a simple anal, this with the exception of (1) P. bellii from West Africa which is characterized by a black dorsal coloring never observed in P.mayombensis sp. nov. and a genetic distance of 4% for the 16S gene, (2) from P. pobeguini from West Africa the West, which has a much lower number ventrals and subcaudals in both sexes and only two supralabials in contact with the eye, (3) of P. rwandae from the Albertine rift which presents a distinctly greater number of ventrals in both sexes, and (4) P. heterodermus from Africa Central and West Africa by a distance genetics of 7% for the 16S gene, as well as by a distinct coloring, more or less evenly green in P. heterodermus and never olive-brown with bluish dots and bars blackish crossbones at the front of the body like in P. mayombensis sp. nov.” (from Trape et al. 2021) |
