(QMJ40098 –40100 now identified as L. hobsoni  sp. nov.). Other material examined is listed in Appendix 1.GoogleMaps 

Diagnosis. Distinguished from all other Lerista  by its combination of enlarged first supraciliary, monodactyl hindlimb, single loreal, usually single preocular, single presubocular and no broad black lateral band.

Comparisons. Lerista cinerea  can only be confused with other Lerista  spp. that also possess an enlarged first supraciliary (resulting from the fusion of the first two supraciliaries). These include the Queensland Lerista wilkinsi  group ( L. ameles  , L. hobsoni  sp. nov., L. storri  , L. vittata  , L. vanderduysi  sp. nov. and L. wilkinsi  ) and also L. apoda  and L. stylis  (both of which are no longer considered members of this group). Lerista cinerea  is separated from L. ameles  and L. apoda  by its hindlimbs (vs. totally limbless), from L. storri  by having a clawed digit (vs. stylar), from L. vittata  and L. vanderduysi  sp. nov. in lacking a broad, dark lateral band (vs. dark lateral band present) and from L. wilkinsi  by the number of digits (one vs. two toes on the hindlimb). It is closest to L. hobsoni  sp. nov. from which it can be distinguished by possessing a single loreal (vs. two loreals). While specimens from the type locality possess a prefrontal scale which distinguishes them from all other members of the L wilkinsi  group, other populations now assigned to L. cinerea  are lacking this character.

Variation. Sample size is 25 unless otherwise noted: SVL = 39–71 mm (59 ± 7 mm); HL = 7–10% SVL (8 ± 1%); HW = 56–69% HL (65 ± 3%); SE = 19–32% HL (25 ± 3%); EE = 44–55% HL (50 ± 2%); RL =14–21 % HL (17 ± 1%); NL = 16–24% HL (19 ± 1%); IN = 19-25% HL (22 ± 1%); EN = 29–37% HL (32 ± 2%); RF = 21–29% HL (24 ± 2%); E = 12–19% HL (15 ± 2%); MW = 5–8% SVL (6 ± 1%); L2 = 5–8% SVL (7 ± 1%); TL = 92–106% SVL (101 ± 5%, n = 6 original tails, all others regrown).

Midbody scale rows 18 (n = 19) or 20 (n = 6); NC = 28–51% (38 ± 6%); NaL = 13–25% (19 ± 3%); FN = 43– 111% (60 ± 20%); FW = 79–117% (96 ± 10%); IW = 70–121% (82 ± 11%); PL = 34–81% (58 ± 9%); MW = 53– 90% (76 ± 10%); prefrontal present (n = 15) or absent (n = 10) – when present, usually contacts preocular, second loreal, frontonasal, frontal and first supraciliary (fails to contact the preocular, n = 2); first supraciliary usually contacts preocular, loreal, prefrontal (when present, frontonasal when absent), frontal, first supraocular and second supraciliary (fails to contact loreal, n = 9); frontal contacts interparietal, frontoparietal, first supraocular, first supraciliary, prefrontal (when present) and frontonasal; preocular usually single (occasionally two, n = 3); 4–5 palpebrals (mode = 4); single postocular (or two, n = 3); single postsubocular (or absent, n = 7); usually two infralabials contacting postmental (n = 10), rarely one (n = 2); 4–5 scales between last infralabial and ear (mode = 4); temporal contacts fourth and fifth supralabials, postocular, pretemporal, second temporal and postsupralabial (sometimes fails to contact postocular, n = 4; sometimes point contact with parietal, n = 5); primary chin shields narrowly separated (n = 16) or in contact (n = 8); 2–8 enlarged nuchal scales (mode = 4), 86–113 paravertebrals (mode = 99); L2B = 7–14 (mode = 9); 6–8 subdigital lamellae under single digit (mode = 7), 3–8 supradigitals (mode = 4), 75–97 subcaudals (mode = 83, n = 6). Presacral vertebrae 47–49 (mode = 48, n = 9); 3 phalanges (n = 6); 45–49 caudal vertebrae (n = 3).

Colouration in preservative. See Greer et al. (1983).

Colouration in life (as different from colouration in preservative) ( Fig. 10 View Figure ). As for spirit specimens but the base colour is silvery grey (fades to pale brown in spirit).

Distribution and habitat ( Figs. 1 View Figure and 12 View Figure ). The distribution of L. cinerea  is centred on the Charters Towers region on the division between the Suttor and Lower Burdekin River drainage sub-basins. Most records are associated with semi-evergreen vine thickets.
