Species description

Geographical Origin and Habitat: Native to Thailand and surrounding islands, where they inhabit mossy rock crevices and dark areas in tropical rainforests.
Taxonomy and Genetics: Family Armadillidae. Features a high-domed, armored body reaching up to 1.5 cm in length. The dorsal carapace is a glossy dark grey or deep black, bordered along the lateral flanges (epimera) by a bright cherry-red or fiery orange coloration.
Behavior and Habits: Primarily fossorial and nocturnal. They are relatively active compared to other Cubaris species but remain shy under direct light, preferring to burrow into the substrate rather than roll into a ball. They spend most of their life cycle under decomposing wood and leaf litter.
Morphology: Sexes are morphologically identical. Sexual dimorphism is not externally visible, requiring examination of pleopods under magnification to distinguish adults.

Care, breeding and tankmates

Terrarium Setup: Requires a tropical setup with deep substrate (7-10 cm) consisting of a moisture-retaining organic mix of soil, peat, and decayed wood. Provide limestone pieces, porous rocks, live moss, and a thick layer of oak leaves.
Lighting and Heating: Avoid direct light. Maintain stable tropical temperatures between 23 and 28°C. Supplementary heating is essential during winter, as cold conditions can halt feeding and colony growth.
Humidity and Hydration: Requires high humidity levels (75-90%). A fine balance is critical; the substrate must be damp but never waterlogged or muddy. Ensure good ventilation using fine mesh screens.
Feeding and Supplementation: Detritivores feeding on leaf litter, decaying wood, and moss. Supplement their diet with high-quality protein (such as krill or fish flakes) and a constant source of calcium (cuttlebone mixed into the soil).
Compatibility: Best kept in a species-only display setup. They are sensitive and should not be housed with predatory amphibians or faster, dominant European isopods that could outcompete them for resources.
Health and Common Diseases: Vulnerable to molting failure (ecdysis issues) if humidity levels drop or calcium is lacking. An incomplete molt can trap the isopod inside its old exoskeleton, leading to death.
