|Diagnosis||Diagnosis.—A relatively small species of Carlia distinguished from other members of the genus by the following combination of characters: scales smooth; size small (maximum SVL 43.2 mm); supralabials usually six; supra- ciliaries usually eight or nine; fewer than 10 supradigital scales on fourth toe, 19–30 lamellae under fourth toe (mean 5 23.9 6 0.12); 24–28 scale rows around midbody (mean 5 26.0 6 0.09); 34–42 paravertebral scales (mean 5 38.6 6 0.17); typically one small, white-tipped ear lobule on anterior margin of ear opening (Fig. 1C in KRAUS 2007); dorsal and lateral surfaces dark brown with a lighter golden-brown dorsolateral stripe separating the two fields (Fig. 2B); tem- porals dark brown; a few light brown or white scales arrayed to form a stripe along the anterior face of the upper forearm and often on the anterior face of the upper hind limb; region between ear and forearm insertion with either a white stripe or scattered white scales (Fig. 2B, C); and a dark orange-red wash on the sides and under the tail in sexually active males. Carlia curta differs from species in the C. bicarinata complex and C. fusca complex in its smooth scales, small size, and only 8–9 supra- digital scales on the fourth toe. Carlia curta differs from C. novaeguineae in having a single conspicuous, pointed, anterior ear lobule (vs. typically none) that is tipped with white (vs. brown, when present); greater number of midbody scale rows (mean 5 26.0 6 0.09 in C. curta vs. 23.6 6 0.27 in C. novaegui- neae); greater number of lamellae under the fourth toe (mean 5 23.9 6 0.12 in C. curta vs. 21.5 6 0.27 in C. novaeguineae); dark brown lateral surfaces, dorsal surfaces, and temporals; light golden-brown dorsolateral stripe on each side; a straw-colored or white stripe along the anterior face of each upper forearm; and straw- colored or white flecks in the region between ear and forearm. Carlia curta differs from C. macfarlani in having a single anterior (vs. several anterior and posterior) ear lobule; a lesser number of paravertebral scales (mean 38.6 6 0.17 in C. curta vs. 42.1 6 0.17 in C. macfarlani); greater number of lamellae under the fourth toe (mean 5 23.9 6 0.12 in C. curta vs. 21.5 6 0.12 in C. macfarlani); dark brown lateral surfaces, dorsal surfaces, and temporals; a light golden-brown dorsolateral stripe; a straw-colored or white stripe along the anterior face of the upper forearm; straw-colored or white flecks in the region between the ear and forearm; and in lacking rows of brown spots ventrally. Carlia curta differs from the other Australian species of the C. novaeguineae complex as follows: from C. foliorum and C. timlowi in having a moveable lower eyelid (vs. eyelid fused to form a spectacle); from C. abscondita, C. laeve, C. malleolus, C. rococo, C. sesbrauna, C. tanneri, and C. zuma in usually having six (vs. seven) supralabials; and from C. aerata in having eight or nine (vs. six or seven) supraciliaries, a round (vs. horizontally elongate) ear opening, and single (vs. many) ear lobules. It further differs from all of these species in the color pattern elements noted above [from KRAUS 2007].|
