Bump-Headed Arboreal Jumper
Cocalus are comparatively large spiders characterised by a carapace that slopes downwards both anteriorly and posteriorly. A low but distinct hump is situated in this area bounded by the PME and PLE.
The male of this species has not been described. However, circumstantial evidence suggests that it was probably described under the name of C. concolor (Type locality: Pulau Bintang in Indonesia).
