CommentBRYGOO (1986) synonymized Cryptoblepharus boutonii mayottensis MERTENS 1928: 83 with Cryptoblepharus (boutonii) gloriosus (Stejneger).

Comparison of subspecies. C. g. gloriosus is distinguished from C. g. mayottensis and C. g. mohelicus by having shorter forelimbs (mean % of SVL: 30.1 instead of 35.4 or more). Further distinguished from C. g. mayottensis by fewer midbody scale rows (mode 22 instead of 24), more palmar scales (mode 12 instead of 10) and larger size (mean SVL 39.8 instead of 36.5 mm). Further distinguished from C. g. mohelicus by shorter snout (mean % of head length: 43.6 instead of 47.3), more paravertebral (mode 51 instead of 47) and plantar (mode 13 instead of 11) scales.

Conservation: “Glorioso and these islands seem to be heavily degraded and full of rats. We can even not exclude that C. gloriosus and the other Glorioso endemics (Amphiglossus valhallae, Zonosaurus madagascariensis insulanus) have become extinct in the meantime. The islands are very small (ca. 5 square kilometres in total) and there might be almost no chance to escape any major threats like rats etc. I therefore think the endemic taxa should be treated as Critically Endangered" and there is an urgent need for a herpetological survey to clarify the situation.” [F. Glaw, pers. comm. 8 June 2011].
