DistributionAustralia (Queensland)

Type locality: second Claudie River crossing, Iron Range road, via Coen, in 12° 44’ S, 143'13’ E, NE Qld.  
Reproductionoviparous 
TypesHolotype: QM J24603; paratypes: QM, AMS 
DiagnosisDiagnosis: A small, short-legged, rock-dwelling Carlia distinguished from all members of this genus except C. scirtetis and C. coensis, in having smoothly curved posterior edges to the mid-dorsal scales, weakly quadricarinate (occasionally with five carinations) dorsal scales; carinations composed of 2-5 small points. For features which distinguish C. rimula from C. scirtetis see diagnosis for the latter species. C. rimula may be distinguished from C. coensis by mid-body scale count (26-30 vs 36-45), colour and pattern (dark brown with gold/silver dorsolateral lines and a midlateralline vs almost black with striking, irregular and broken, gold, dorsolateral, vertebral and midlaterallines), in having short limbs, and in being dorsoventrally depressed (from Ingram & Covacevich 1980: 46). 
CommentCarlia rimula is nested within Lygisaurus, with L. parrhasius as sister species, in a comprehensive genetic analysis of 1384 exon sequences (Bragg et al. 2018) 
EtymologyFrom the Latin rimula (a little cleft), alluding to the rock-dwelling behaviour of this species, which shelters in narrow crevices. (G. Shea, pers. comm., 9 Feb 2024)
