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 24 to 500 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

(e.g., Rodda 2020, Munoz Nolasco 2015: "En P. dugesii, la actividad inicia a las 09:30 h y termina a las 15:00 h. En esta especie también se observó un patrón diurno bimodal, pero, a diferencia de P. brevirostris, el primer pico de actividad (entre 10:30 y 11:00 h) fue menos marcado que el segundo pico (alrededor de las 14:00 h). Ambos estuvieron separados por un valle entre las 11:30 y 13:00 h")

Keeping one
Duges' Skink is assessed as Vulnerable on the IUCN Red List. Species at risk in the wild are often covered by CITES and by national law, which decide what may be bought, sold, moved across a border or kept at all — and captive-bred and wild-caught animals are usually treated differently. Check the rules where you are before acquiring one. Nothing below is a judgement about keeping this species; it is what a published welfare standard says about space, and what the animal itself was measured doing.
11.5 in × 11.5 in × 7.25 in(29 × 29 × 18 cm)
Minimum length × width × height, for one animal. Bigger is always better.
The standard sizes ground-dwelling species at 4 × 4 × 2.5 times snout-vent length.
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 2.75 in (72.2 mm), at 4 × 4 × 2.5 times it, following the German federal welfare standard — how this is worked out.
No preferred body temperature has been recorded for Duges' Skink. Rather than repeat a number from a care sheet, this page leaves it out.
Feeding
1kJ per day
Worked out for an animal of 8 g, the heaviest recorded for Duges' Skink — 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.
