DistributionGabon (endemic)

Type locality: “Gabon, à environ 50 kilométres sud-ouest de Lambaréné” [50 km southwest of Lambarene]  
TypesHolotype: MNHN-RA 1901.0531 
DiagnosisDifferentiation between C. haughi and C. bifrontalis is relatively minor (Gans 1987). It involves the lack of a discreet ocular in C. haughi (present in C. bifrontalis), and a caudal autotomy site at the level of the 7th caudal annulus (at the 11th in C. bifrontalis). Cynisca haughi may also have higher body annuli counts (251 in the holotype), although more material is required for confirmation. The holotype of C. bifrontalis has 240 body annuli, whilst in the Toucan-Rabi series they range from only 229 to 231.

Diagnosis: Gans 1987: 39 
CommentAbundance: only known from the type specimen (Meiri et al. 2017). 
EtymologyNamed after M. Haug, presumably the collector. Note that the original spelling used by Mocquard is “Haugi” not “haughi”.
