The Saharo-Sindian genus Trapelus contains 14 species, four of which occur in northern Africa. One of these taxa, Trapelus mutabilis, has a very widespread distribution from West to East Africa along the northern Saharan border. It has been identified as a species complex that includes several cryptic taxa. Together with a key of the so far described African species of the genus, the description of the first of these ciyptic taxa is presented here. Keywords. Squamata, Agamidae, Trapelus sp. n., Africa, Chad, Ennedi mountains. 1. INTRODUCTION In his guiding work Moody (1980) revised the family Agamidae and resurrected the genus Trapelus Cuvier, 1816. The taxa of the genus are characterized by short and thick heads and a small, deeply sunk tympanum with some spiny scales above the ear-opening. About 14 species of the genus are recognized and are distributed from north- western Africa, along the Saharan border, through the Near East to southwest and central Asia. Four of them occur in Africa [Trapelus mutabilis (Merrem, 1820): northern Africa; Tixipehispallidus {Rquss, 1833): Egypt; Trapelus savignii (Duméril & Bibron, 1837): Egypt; Trapelus tournevillei (Lataste, 1880): Algeria, Tunisia.] with a dis- tribution centre in north-eastern Africa. Most of the Egypt- ian taxa occur eastwards to the Near East and Egypt is the westernmost border of their distribution. The synonymi- sation of T. flavimaculatus with T. savignii by Saleh (1997) is not followed by us in this article, because Saleh (1997) failed to give reasons for this important taxonom- ic step. The two taxa are clearly distinct both in mor
