|Diagnosis||Diagnosis. A medium-sized lizard with a moderately long tail. A pair of nuchals is present, the supranasals are usually separated, the prefrontals form a distinct suture in most specimens. Only one scale between the fourth supraocular and the anterior supratemporal. The posterior supratemporal is larger than the anterior one. Dorsals tricarinate. The number of lamellae under the fourth toe varies between 14 and 18, but mostly is 15 or 16. Under the fourth finger there are 11-15, mostly 11 or 12 lamellae. Brown above, flanks dark-brown, either ventrally bordered by a narrow white lateral line or not. Belly greenish-white, males with black spots on the throat. A light spot on the side of the neck in adult specimens (Hoogmoed 1974: 14).|
The most constant character is the number of scales between the fourth supraocular and the anterior supratemporal. In albilabris this always is one, no specimens were found with two scales. In affinis the number is nearly always two, only exceptionally it may be one. Another important character in which the two species differ is the number of subdigital lamellae, low in albilabris, high in affinis. This is not a very clear-cut character because a certain amount of overlap occurs (Figs. 5, 16), but it is safe to say that specimens with 14 or 15 lamellae under the fourth toe and 11 or 12 lamellae under the fourth finger are M. albilabris. In life M. albilabris shows a wide yellow zone from the lips to the insertion of the forelimbs or a yellow spot just in front of the forelimbs. In M. affinis there never is any yellow on the dorsal and lateral surfaces, at most the upper lips are orange. In M. albilabris the throat in males has black spots more or less clearly arranged in longitudinal rows. In M. affinis the throat is nearly always immaculately white. The ventral surface in preserved M. albilabris is bluish white, whereas in M. affinis it is pure white or yellowish white. (Hoogmoed 1974: 23).
|Comment||Synonymy after HOOGMOED 1974. Schmidt (1919) considered albilabris (as previous authors) as a synonym of blandingii (= affinis). Euprepes aureogularis MÜLLER 1885 has been removed from the synonymy of T. albolabris.|
Distribution: Not listed in LeBreton 1999 for Cameroon.
Similar species: T. affinis (and others). See Diagnosis.
|Etymology||Named after Latin “albus, -a, -um” = white and “labrum” = lip.|
