Sexual size dimorphism is moderate, with adult males (up to 227 mm carapace length) smaller than females (up to 300 mm). The species occupies streams between 600 and 1100 m elevation that contain permanent pools deeper than about 2 m, frequently with granite boulders and bedrock, and often with underwater caverns formed by boulders, logs, and overhanging banks. In areas of lower water velocity, the typical substratum is coarse granitic sand overlain by fine silt, algal growth, and dense beds of macrophytes.
