DistributionEgypt (North Sinai [HR 32: 59]), Sudan, Ethiopia, Eritrea, Somalia, Kenya, Uganda, Cameroon

keniensis: Type locality: Lake Baringo

perreti: Cameroon, Nigeria; Type locality: “Soulede, Mokolo, N Kamerun”

Type locality: Egypt  
Reproductionoviparous 
TypesHolotype: lost (probably, fide SCHÄTTI 1988).
Holotype: MHNG 1464.45, male; paratypes: BMNH 1975.1074 [juv., probably from Bambour (Bambur) area, Nigeria], BMNH 1975.1141-42 (juv. female and ad. female, Bambour), USNM 125691 (female, Marama, Nigeria), ZFMK 18686 [juv. female, Benoue (Garoua), Kamerun]. [perreti]
Holotype: BMNH 1946.1.13.87 (orig. 1932.5.2.7), collected by E.B. Worthington, 1930 [keniensis] 
DiagnosisDiagnosis (perreti). A subspecies of C. florulentus distinguished from the nominate race by 25 (instead of 21-23) dorsal scale rows at midbody. It differs from f. florulentus and f. keniensis in higher ventral counts (219 versus 214 or fewer in males, 226-231 against 205-228 in females), and more maxillary teeth (16-17 instead of 15 or less). 
CommentDistribution: Not explicitely listed by SCHLEICH, KÄSTLE & KABISCH 1996. The author is “GEOFFROY 1809: 67” fide DUMÉRIL et al. 1854. Reports from Libya represent Hemorrhois algirus or possibly P. rogersi (Bauer et al. 2017).

Subspecies: Schätti 2014: 384 elevated perreti to full species. However, the only difference he mentions is that perreti has 25 dorsals (vs. 27-29 in the Platyceps florulentus complex)
