|Distribution||Australia (Western Australia)|
Type locality: Australia (but see note below).
|Types||Holotype: MNHP 1246, from Australia (original description cites Cape of Good Hope, southern Africa), see Guibé (1954) [Brachystopus lineopunctulata].|
Holotype: BMNH (not found), from W. A. [Ronia catenulata]
Syntypes: BMNH 1918.104.22.168-77, from Australia.
|Diagnosis||Diagnosis. A species of Lerista with forelimb only a short stump (L1 = 0.7–1.2% SVL), two digits on a relatively short hindlimb (L2 <14% SVL), fused frontoparietals, four or five supraciliaries and a free eyelid (vs. fused into a transparent spectacle) (AMEY & EDWARDS 2017).|
Comparisons. Only three other species of Lerista, L. connivens, L. miopus and L. varia, have the combination of forelimb with a nubbin or stump, two digits on the hindlimb, free eyelid and interparietal fused to the frontoparietals. Lerista lineopunctulata differs from L. connivens in a more developed forelimb (a stump 0.7–1.2% SVL vs. usually a depression only or a nubbin no more than 0.6% SVL), a reduced hindlimb (up to 14% SVL vs. 13–23% SVL, 7–10 subdigital lamellae on longest toe, homologous to digit IV, see Greer (1987, 1990) vs. 11–14, 5–7 supradigital scales on longest toe vs. 8–11), more supraciliaries (5 vs. 4) and colour pattern (brown-grey dorsally with lines of dark brown spots, pattern fading laterally vs. two irregular lines of dark brown enclosing a paler brown vertebral stripe and a solid dark brown upper lateral stripe). From L. miopus, it differs in a more developed forelimb (a stump 0.7–1.2% SVL vs. usually a depression only or a nubbin no more than 0.7% SVL) and more distinct colour pattern (lines of dark brown spots vs. often so indistinct as to appear patternless). From L. varia, it differs in a more developed forelimb (a stump 0.7–1.2% SVL vs. usually a depression only or a nubbin no more than 0.4% SVL), a reduced hindlimb (up to 14% SVL vs. 13–24% SVL, 5–7 supradigitals on the longest toe vs. 8–10), more paravertebrals (76–88 vs. 63–73) and a generally bolder colour pattern (usually brown-grey with lines of dark brown spots dorsally vs. usually 2–4 indistinct lines of dark brown spots) (AMEY & EDWARDS 2017).
|Comment||Synonymy partly after COGGER 1983.|
Type species: Rhodona punctata Gray, 1839 is the type species of the genus Rhodona Gray, 1839. This genus was resurrected by WELLS 2012: 22, who also provides a diagnosis of the genus. Unfortunately WELLS did not provide a phylogenetic analysis of the genera, into which he broke up Lerista, hence we leave the current genus Lerista intact for the time being.
