TypesHolotype: QM J85244, mature male with turgid opaque testes, collected 20 July 2007 by S. Williams & C. Moritz. Paratypes: QMJ38195, adult female with developing follicles, 17 km ENE of Mt Croll (13o46' S, 143o19' E), McIlwraith Range, collected 2 June 1979, J. W. Winter & R. G. Atherton; QMJ66642, adult female with developing follicles, Peach Creek headwaters (13o44'15", S 143o20'20" E, 530 m a.s.l.), McIlwraith Range, collected 25 August 1998 by K. McDonald & J. Covacevich; QMJ70609, gravid adult female, McIlwraith Range (13o44'01" S, 143o20'09" E, 530 m a.s.l.), collected 16 August 1999, K. McDonald, A. Freeman & H. Hines. 
DiagnosisDiagnosis: Glaphyromorphus nyanchupinta sp. nov. is diagnosed from all congeners in having: narrowly separated adpressed limbs (not separated by more than the length of the forelimb); more than 24 midbody scale rows; the prefontal separated from the preocular; small body size (max SVL ~ 54 mm); seven supralabials (with 5th below centre of eye); fewer than 21 lamellae beneath 4th toe; a strong barred body pattern extending to hindlimbs; dark supralabial scales with a central white dot; dark streaks typically present on throat.

Comparison with similar species. Glaphyromorphus nyanchupinta sp. nov. can only be confused with G. othelarrni sp. nov., G. fuscicaudis and G. nigricaudis. It is readily distinguished from all three species by its small body size (max SVL = ~ 54 mm vs > 85 mm), less robust form (WT/SVL 0.04–0.06 vs > 0.09); number of subdigital lamellae beneath the 4th toe (17–20 vs generally 20 or more) (Table 1 in Hoskin & Couper 2014); labial pattern (supralabials predominantly dark, enclosing a central white dot vs supralabials pale with dark barring along sutures) (Fig. 4B), lateral head and neck pattern (dark reticulations vs dark bars or spots) (Figs 3B, 5B); the extent of the body pattern (dark dorsal and lateral bars extend posteriorly to hindlimb vs pattern generally strongest on anterior half of body and breaking up or absent beyond midbody) (Figs 3B, 5B); and dark streaks typically present on the throat (Fig. 9) vs throat typically unmarked. Glaphyromorphus nyanchupinta sp. nov. is further distinguished from G. othelarrni sp. nov. in having a proportionately shorter tail (TL/SVL 1.00 vs 1.47–1.86); shorter limbs (L1/SVL: 0.20–0.21 vs 0.22–0.26; L2/SVL: 0.28–0.32 vs 0.33–0.41); fewer midbody scale rows (25–27 vs 28–30); fewer subdigital lamellae beneath the 4th finger (10–11 vs 14–15); and fewer supralabial scales (7 with 5th below centre of eye vs typically 8 with 6th below centre of eye) (Table 1). It is further distinguished from G. fuscicaudis in having a proportionately larger head (HW/SVL: 0.13–0.14 vs 0.12–0.13; HL/SVL: 0.18–0.19 vs 0.16–0.17); fewer midbody scale rows (25–27 vs 28–30); and generally fewer paravertebral scales (mean 59 vs 64) (Table 1). It also lacks the series of yellow dorsolateral blotches that are prominent in G. fuscicaudis (Figs 5B, 5C). It is further distinguished from G. nigricaudis in having fewer paravertebral scales (56–60 vs 51–56) (Table 1). 
CommentAbundance: only known from its original description (Meiri et al. 2017).

Limb morphology: 5 digits, 5 toes (Singhal et al. 2018, Cogger 2014) 
EtymologyNyanchupinta translates as: ‘nyanchu’ for ‘dead leaves or mulch’ and ‘pinta’ for ‘covered’, referring to the lizard being hidden in the leaf-litter. The species was named by Elders of the Kaantju clan, traditional owners of the McIlwraith Range where the species lives.
