Type locality: Egypte; restricted to El Arish, northern Sinai, Egypt, by neotype designation.  
Reproductionoviparous 
TypesNeotype: ZFMK 77470, designated by WAGNER & CROCHET 2009. 
DiagnosisDiagnosis: Diagnosis: Medium-sized Trapelus [largest known voucher from Egypt SVL 123 mm (Anderson, 1898)] with an average ratio TL/SVL of 1.3. Gular pouch well developed. Dorsal scales relatively uniform with intermixed larger scales. Ventral scales keeled. Usually vertebral scales slightly larger than the scales on the flanks. Coloration uniformly sandy grey with five brown transverse bands, which are inter- rupted by a yellowish stripe and whitish lines on the body and a barred tail. Additionally two transverse bands are on the interorbital area. Adult males get a characteristic coloration under nuptial conditions: throat and flanks bright to violet blue, the flanks with interspersed white spots. Additionally, pregnant females have a special coloration, with dorsal bands becoming brick red (from Wagner et al. 2011: 904). 
CommentSynonymy after WERMUTH 1967.

Distribution: see map in Kissling et al. 2016: Fig. 1 and Bar et al. 2021.. Not in Israel where it is replaced by P. agnetae. 
EtymologyNamed after Marie Jules Cesar Lelorgne de Savigny (1778-1851), a zoologist and artist. He studied medicine, but turned to zoology.
