Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| E. S. Gaffney et al. 2006 | Members of the subfamily Bothremydinae with the following unique characters: jugal-quadrate contact present; supraoccipital-quadrate contact absent (except in unnamed taxon CNRST-SUNY 199); small palatine contribution to triturating surfaces; dorsally arched palate (except in Labrostochelys, but unknown for Taphrosphys and Rhothonemys); maxilla-quadratojugal contact absent. Other differentiating characters are: preorbital part of skull usually narrower than in Bothremydini; fenestra interorbitale high, in contrast to Bothremydini; temporal emargination slight or absent, in contrast to Kurmademydini and Cearachelyini; fossa precolumellaris absent, in contrast to Kurmademydini; shelf below cavum tympani present, as in Bothremydini; foramen jugulare posterius closed, as in Kurmademydini and Bothremydini; exoccipitals completely form neck and condylus occipitalis, in contrast to Kurmademydini and Cearachelyini; foramen stapedio-temporale not visible in dorsal view; foramen stapedio-temporale and foramen nervi trigemini very close together; fenestra postotica closed; jugal not retracted from orbit; pectoral scales on plastron reach entoplastron; neurals do not reach suprapygal; (following characters known only for Taphrosphys): shell surface covered by strong texture consisting of irregular raised polygons delimited by network of deep furrows; nuchal notch absent; seven neurals, costals 7 and 8 meeting on midline; first costal length greater than twice length of second costal; first marginal scale about equidimensional, pleural scales extending well onto peripheral bones; (following characters known only for Taphrosphys and Ummulisani): shell surface covered by strong texture consisting of irregular raised polygons delimited by network of deep furrows; posterior plastral lobe broad, in contrast to Chedighaii, and possessing a semicircular anal notch; intergular scale large, separating small gulars, humerals, and part of pectorals; pubic scar long and narrow, ischiac scar round and near edge of xiphiplastron. |
