Northern Flinders Ranges froglet
Species Description: Donnellan S, Anstis M, Price L, Wheaton L 2012 A new species of Crinia (Anura: Myobatrachidae) from the Flinders Ranges, South Australia. Zootaxa 3499: 1-26.
Diagnosis: C. flindersensis is distinguished from other Crinia species mainly by coloration or larval morphology. Adult C. flindersensis are morphologically indistinguishable from adult C. riparia, its sister species, but are distinguished morphologically by their tadpoles. C. flindersensis tadpoles are more rounded in shape, have a more arched tail fin, a shorter tail, and a narrower oral disc less adapted to fast flowing water (Donnellan et al. 2012).
Coloration in preservative: The dorsum and flanks are an unpatterned dark gray. The snout is black with brown lips. The abdomen is cream colored with dark grey patterning. The dorsal surfaces of the limbs are a lighter grey with dark grey banding while the ventral surfaces are brownish. Dorsal and ventral patterns can vary, even within populations (Donnellan et al. 2012).
Tadpole Coloration: The colors seen in C. flindersensis tadpoles vary both within populations and between localities. The dorsum may be bright gold, dark golden brown, reddish brown, black, dark brown, or rusty brown. The venter is translucent, and over time accumulates bright copper-gold clusters that eventually create a nearly opaque layer by stage 34 (Donnellan et al. 2012).
Distribution and Habitat
C. flindersensis tadpoles are bottom dwellers and are found in slow moving or still portions of the creeks (Donnellan et al. 2012).
Life History, Abundance, Activity, and Special Behaviors
Trends and Threats
C. flindersensis is named for the Flinders Ranges, the South Australian mountain ranges where the species is found (Donnellan et al. 2012).
C. flindersensis is mostly closely related to the Southern Flinders Ranges froglet, C. riparia, and is also closely related to C. signifera (Donnellan et al. 2012).
Littlejohn and Martin (1965), in their paper describing C. riparia, included specimens from within the range of C. flindersensis in their analysis. They acknowledged, however, that these may have been biologically distinct and did not use them for their C. riparia description (Donnellan et al. 2012).
Due to taxonomic confusion, specimens of C. riparia from within the Flinders Range are likely C. flindersensis.
