DistributionAustralia (New South Wales)

Type locality: 15 km S, 32.3 km E of Nowendoc (31°39'S 152°04'E), New South Wales.  
TypesHolotype: AMS (AM) R44654; now Utah Museum of Natural History, Salt Lake City. 
DiagnosisDiagnosis (Flaviemys): A genus of short-necked turtles with the following character combination: (1) broad cervical scute; (2) bright yellow coloration on the ventral marginal and the plastron; (3) bright yellow stripe on the ventral aspects of legs, running from the plastron to the distal of the first toes; (4) three bright yellow stripes on the tail, with one mid-ventral and the others lateral; (5) bright yellow marking on the ventral distal tip of the tail; (6) neural bones present.

Diagnosis: A member of the Elseya latisternum complex readily separated from all other Elseya, by the excellent illustrations and descriptions of Cann (1978: Plate 65, mature male, Plates 66-67, mature female, Plate 64 habitat of this species). The presence of a bright yellow facial streak readily separates this species from Elseya latisternum. Found in rivers of north-eastern New South Wales. Cogger (1983) provides diagnostic illustrations of its nearest relative, Elseya latisternum (Plates 408–410). 
CommentSynonymy: Might be synonymous to E. georgesi from which it differs “in a number of subtle colour differences... including a black horizontal bar through the eye” (which purvisi has but georgesi lacks; COGGER 2000).

Myuchelys purvisi and M. georgesi are cryptic species (Georges & Adams, 1996; Thomson & Georges, 1996) differing overtly only in intensity of colouration.

Type species: Elseya purvisi WELLS & WELLINGTON 1985: 8 is the type species of Flaviemys LE et al. 2013. The genus was rejected by Spinks et al. 2015, based on molecular data. 
EtymologyEtymology (Flaviemys): The generic name ‘‘Flaviemys’’ is based on a distinctive yellow color pattern on the plastron of the species. From the Greek, flavus (yellow) and emys (turtle).

Etymology: Named for Malcolm Purvis of North Sydney, New South Wales, noted herpetologist [from GEORGES & THOMSON 2010].
