DiagnosisDiagnosis A relatively small member of the genus Elseya (see Joseph-Ouni & McCord 2019a,b for measurements of additional species) in New Guinea that is characterized by the following combination of features (Plates 2a-c): A relatively low, evenly rising, oval carapace with low midline apex, that is rusty or chestnut brown in wild coloration and that typical lacks any defining pattern or black blotches in adults; strongest (sharpest) portion of narrow vertebral keel present in adults from the posterior portion of V4 through to the full length of V5; all marginals even (level) to one another on the outer edges, hence lacking any noticeable marginal serration; posterior marginal flaring minimal; keratinous head shield fully developed, dipping minimally behind posterior eye orbit; narrow longitudinal (parietal) head casque extensions of the posterior head shield reaching to make contact with the dorsal rim of the tympana at the anterior (‘12 o’clock’) position; posterior head shield squared off at its terminus; eye uniquely almost completely darkened black in wild coloration but giving way to a dark chestnut-iris with minimal yellow flecking in captivity; a uniformly dark gray maxilla and dark mandible; V2 typically octagonal shaped, having four unequal sides on each side of length wise symmetry where V2 meets adjacent scutes sulci; IH sulci relatively shortest (posterior-most point of IG scute closest to H-P sulcus) of all currently described Elseya species in New Guinea (except for E. rhodini). Sexual dimorphism is present, with males having slightly more depressed shells than females and smaller size, and by an elongate head and pointed face in females but shortened, rounded face in males (JOSEPH-OUNI & MCCORD 2022).
