Biology; Zoology. 82 Philipp Wagner & Wolfgang Böhme; A new species of Trapelus from arid central Africa 2. RESULTS & DISCUSSION Trapelus schmitzi sp. n. Holotype. ZFMK 2590; Guelta Archei, Ennedi Moun- tains, Chad; leg. G. Niethammer, April 1954. Diagnosis. A small species of Trapelus, with a short and thick head, a dark throat and a homogenous, smooth to feebly keeled dorsal scalation intemiixed with a few larg- er keeled scales of the same shape. Scalation of hindlimb homogenous. The new species differs from all described African of the genus by its body proportions, a short tail, its dorsal scalation and the uniformly dark-coloured throat. Trapelus schmitzi sp. n. differs: - from T. savignii (type locality: Egypt) and T. ßavima- culatus (type locality: Djetta, Arabien) in having smooth ventral scales and in having a very small guiar pouch instead a large one. - from T. imitabilis (type locality: Egypt) in having no keeled, enlarged dorsal scales, in a higher number of preanal pores (8 to 12 in T. mutabilis [Schleich at al. 1996] instead of two rows of 18 [10+8] in T. schmitzi sp. n.), a shorter tail (average of mm in T. muta- bilis and mm in T. schmitzi sp. n.) and a more or less homogenous dorsal scalation. - from T. pallidus (type locality: 'Oberägypten'= sou- thern Egypt) in having a homogenous hindlimb scala- Fij;. 1.
