Distribution Notes:

Fiji (endemic). Viti Levu.


Although no collections of C. cryptus workers are known subsequent to Mann's expedition, malaise trapping has produced a dozen male specimens from across Viti Levu that closely match the morphology predicted by the worker caste.


In Fiji. Cerapachys cryptus, together with C. fuscior and Cerapachys sp. FJ06, is distinguished from the other lineages of its Fijian congeners by its 9-segmented antennae and vestigial eyes. It is separated from the aforementioned species by its paler orange color, more broadly attached subpetiolar tooth, and rougher appearing micropunctate sculpture interspersed with foveae of smaller diameter. The eyes of C. cryptus appear entirely absent on most worker specimens, and only among a few examined is the faintest hint of an ommatidium observed.
