Diagnosis

|---|---|---|
| J. R. Bourque 2012 | Kinosternon pojoaque resembles members of the Kinosternon flavescens group in that it possesses a raised M9, which is a synapomorphy unique to that clade. The new species is unique from the extant flavescens group, however, in possession of the following characters: plastral bridges of hyoplastra and hypoplastra flat (with little to no upward incline) and lack longitudinal groove along the axillary and inguinal scutes when viewed ventrally (shared with Kinosternon angustipons Legler, 1965, Kinosternon dunni Schmidt, 1947, Kinosternon sonoriense (Fig. 7), Kinosternon hirtipes, Kinosternon herrerai, and other Central- South American Kinosternon); plastron short with regard to overall carapace length (∼81–82%, shared with K. angustipons, and male Kinosternon hirtipes megacephalum Iverson, 1981, and male K. herrerai); presence of well-defined lateral keel on bridge peripherals 4–6 adjoining outer margins of marginals 4–7; plastral forelobe relatively squared at gular margins, becoming slightly constricted along margins of anterior humerals (shared with Kinosternon sonoriense longifemorale Iverson, 1981, and K. herrerai), with relatively narrow contact at the hyoplastra (different from the extant flavescens group, which has broad forelobe contact); plastral hindlobe ∼1–2% longer than forelobe (shared with Kinosternon durangoense); marginals 10 and 11 nearly equally elevated (shared with Kinosternon arizonense); dorsal margin of fossa orbitalis relatively flat along prefrontal and postorbital (not upwardly inclined as in the flavescens group); dorsal ridges of parietals converge more anteriorly than typical for Kinosternon before contributing to supraoccipital crest (shared with K. herrerai). |
