Common Names
Synonym	Caledoniscincus cryptos SADLIER, BAUER & COLGAN 1999: 74
Distribution	New Caledonia (ranges near Col d’Amieu in the central ranges). Type locality: 8.3 km from Kouaoua/Canala road intersection on La Foa road, New Caledonia (21° 34’ S, 165° 49’ E)
Reproduction	oviparous (not imputed, fide Zimin et al. 2022)
Types	Holotype: AMS R135141, collected by R. Sadlier, 18.iii.1990
Diagnosis	Diagnosis: Caledoniscincus cryptos is recognised mainly on the following electrophoretic characteristics: (i) it is homozygous (in the only available specimen) for an allele of Gapdh(A) which is found nowhere else in our samples; (ii) it is also homozygous for Fbp(C) and G3pdh(A) which are found only as single heterozygotes in non-sympatric C. orestes or C. haplorhinus respectively; (iii) it has fixed differences from morphologically similar C. renevieri and C. auratus at these three loci; (iv) additional fixed differences from C. renevieri are found at Idhp-1 and Pep:LA; (v) an additional fixed difference from C. auratus is seen at Pgah. Caledoniscincus cryptos can also tentatively be distinguished from most other species of Caledoniscincus by the following combination of characters: (a) moderately small, 45 mm SVL; (b) midbody scales in 30 rows; (c) paravertebral scales in 51 rows; (d) adult male dorsal colour pattern transversely oriented and without a pale vertebral stripe; (e) lateral surface without a pale midlateral stripe; (1) rostral shield with a dark midrostral streak. (Sadlier et al. 1999) Unfortunately we had to temporarily remove additional information as this was scraped by multiple AI companies who sell that data. However, these details, e.g. detailed descriptions (about less than half a page) are available for collaborators and contributors. Please contact us if you need any of this material.
Comment	Abundance: only known from the type locality (Meiri et al. 2017).
Etymology	Named after the Greek “cryptos”, for hidden or concealed, alluding to the recognition of this species through genetic analyses only (i.e. different patterns in protein electrophoresis).
