Longer than 50% of all species in Tropiduridae 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 57 to 177 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

"Individuals of S. philmayi sp. nov. were observed during sunny days between 800 and 1400 hours basking on fallen logs close to trails that border or cross patches of forest. One adult male specimen was collected basking in the understory vegetation at 1 m in height. Other individuals were observed basking on rocks in patches of cacti and also on rocky fences with bushes near houses." (Venegas et al. 2021b)

Keeping one
15 in × 15 in × 15 in(38 × 38 × 38 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.
Lives on rock, so stable hard surfaces and basking ledges suit it.
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 3.75 in (95 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 Stenocercus philmayi. Rather than repeat a number from a care sheet, this page leaves it out.
Feeding
4kJ per day
Worked out for an animal of 31 g, the heaviest recorded for Stenocercus philmayi — 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.
