Costa Rica: cloud forests of Cordillera de Tilaran, Cordillera Volcanica Central, Cordillera de Talamanca.
Cryptopone gilva is restricted to cloud forest habitats. For example, it is common in the ridge crest cloud forest in the Monteverde area (1400-1600m), rare around "El Aleman" at the head of the Penas Blancas Valley (900m), and absent at Casa Eladio further down the valley (800m). In Monteverde it is common under loose bark of dead wood and under epiphyte mats in the low arboreal zone: ground level to a few meters high. I often encounter lone founding queens. I find colonies in logs at a certain stage of decay, when the bark comes off in intact sheets, and there is a thin layer of decayed humus between the bark and the still hard wood. Workers are found thinly scattered in anastomosing tunnels in the humus layer. As a bark sheet is peeled away one to five workers may be revealed, which quickly disappear into holes in the wood and under adjacent bark. I have never been able to collect more than a few dozen workers from a colony, and I have never found an obvious colony center or distinct galleries with aggregations of workers and brood. Occasional larvae and pupae occur in the tunnels. The nesting behavior is very similar to that of Typhlomyrmex rogenhoferi, a species more common at lower elevations.
Specimens are occasionally taken in samples of sifted leaf litter (Winkler samples).
