| Diagnosis | Diagnosis: As similar to C. triacantha, this species is morphologically distinguished from other Carlia species by having three strong keels in scales, prefrontals more often in contact or very narrowly separated and usually six supraciliaries. As above-mentioned, in contrast with it closest relative, C. triacantha, this species has longer body size, a relatively longer head and tends to have more ear lobules, on average nine very small lobules (Figs. 4 and 5, Table S7). Another possible trait to distinguish between these species is a white line that begins posterior to each hind limb and can extend to midway through the tail (Fig. S9B). This trait is more evident in freshly caught individuals, or photographs of them, than in long preserved specimens and needs to be further tested through more observations on genetically typed individuals. Genetically diagnosed from C. triacantha, by three ND4 mtDNA sites (Table 2) and geographically by occurring in the Kimberley, although geographic diagnoses in Northern Territory requires further work. |
| Comment | |
| Etymology | Isostriacantha is derived from equal in greek (isos) with triacantha, (three spines, referring to the three keels in scales) due to the difficulty of morphologically distinguishing from its sister species C. triacantha. |
