Graptemys pearlensis — RHODIN et al. 2010 
DistributionUSA (Mississippi, E Louisiana)

Type locality: Mississippi, Copiah County, Pearl River at State Highway 28, near Georgetown  
Reproductionoviparous. 
TypesHolotype: CM 62162 (=). Collected by T.E. Magers, 23 September 1967. D.E. Hahn collection, field number DEH 3400 
DiagnosisDiagnosis. — A high-domed Graptemys with large females and small males, like G. gibbonsi, but typically with a single, generally narrower (relative to G. gibbonsi), vertical, yellow bar on the upper surface of each marginal scute (Fig. 6). A continuous black to brown vertebral stripe is usually present on the carapace. The yellow pigment bar on the 12th marginal scutes is usually 50% or less of those scute lengths along the same axis as the pigment bar (Fig. 7). When longer, the pigment bar tends to be located more distal from the seam between the 12th marginal scutes than it is in G. gibbonsi (Fig. 8). The head pattern is similar to that of G. gibbonsi and usually consists of a prominent, three-pronged, yellow nasal trident on the snout, and the postorbital blotches are connected to the interorbital blotch.
 
CommentSynonymy: Praschag et al. 2017 found that G. ernsti, G. gibbonsi, G. pearlensis and G. pulchra are nearly identical genetically and, thus, likely conspecific. Originally, G. pearlensis was recognized as part of G. pulchra by Baur (1893) and subsequent authors until Lovich and McCoy (1992) described G. gibbonsi, which also included what is now recognized as G. pearlensis. Later, Ennen et al. (2010) split G. gibbonsi (sensu lato), restricting G. pearlensis to the Pearl River and G. gibbonsi (sensu stricto) to the Pascagoula River.

Habitat: freshwater (lakes, rivers)
