Longer than only 32% of all species in Gymnophthalmidae anyone has measured.
The bar is the rank itself: its length is the share of the family this animal exceeds. The chart below is the family’s real spread, on a logarithmic scale because body length here runs from 28 to 121 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

"All specimens were lying inside the water stored in the bromeliads… Specimens from Copal, in Amazonas department, were found on the border of a small lagoon, under a rock (CORBIDI 18900) and among trash (CORBIDI 18901) in a patch of bunchgrass. Specimen CORBIDI 22197 from Fundo Alto Nieva,was found crossing a road in an area of dense montane forest. Specimen CORBIDI 19955, from Quebrada Gajmal, was collected when it fell from the stick roof of a house surrounded by cattle pasture and patches of secondary montane forest" (Echevarria et al. 2021)

Keeping one
8.25 in × 8.25 in × 8.25 in(21 × 21 × 21 cm)
Minimum length × width × height, for one animal. Bigger is always better.
The standard sizes ground species at 4 × 4 × 2.5 and climbing species at 4 × 2.5 × 4 times snout-vent length.
Recorded both on the ground and climbing, so this is the larger of the two rules in every dimension.
Mindestanforderungen an die Haltung von Reptilien (Sachverständigengutachten), German Federal Ministry for Nutrition, Agriculture and Forestry, Animal Welfare Division, 10 January 1997. The standard states these floor areas are recommendations rather than binding limits.
From this animal’s own snout-vent length of 2 in (52.2 mm), at 4 × 4 × 4 times it, following the German federal welfare standard — how this is worked out.
No preferred body temperature has been recorded for Elusive Microtegus. Rather than repeat a number from a care sheet, this page leaves it out.
Feeding
1kJ per day
Worked out for an animal of 3 g, the heaviest recorded for Elusive Microtegus — so it is the top of the range, not a figure for a particular animal. Weigh yours and the number will be lower.
An upper estimate, not a feeding target, and not veterinary advice. The equation covers only what an animal burns staying alive, so a growing, gravid or recovering animal needs more — and it was measured on wild animals, which move far more than one in an enclosure. Body condition and a vet who knows the species are what a feeding decision should rest on. Where this comes from.
What nobody knows
These are not gaps in our research. No scientific dataset records them for this species — and saying so is information you cannot get from a reference that simply leaves a field out.
