Engaeus cymusKeith A. Crandall
TypesSyntypes, Museum of Victoria, Melbourne J895 (2 male, 2 female). Other 31 syntypes apparenty lost (see Lew Ton & Poore 1987).
DistributionE. cymus displays one of the largest geographical distributions of all Engaeus species, occuring mainly north of the Great Dividing Range. It is one of only three species of Engaeus to be found above 1000 m in altitude.
HabitatE. cymus occupies a wide variety of habitats, but mostly usually those in creeks and seepages in either dry or wet sclerophyll forests. The type of burrow constructed appears to depend on the nature of the soil. For instance, when the soils are comparatively shallow and rocky, small individuals of this species can be collected from narrow, ramifying burrows which twist around large rocks in the low banks of creeks and rivers. Such burrows are difficult to search and a low capture rate often results. These type 2 burrows and their respective soil conditions occur over the entire range of this species and individuals of Euastacus sp. can frequently be found in transverse sympatry, occuring in either type 1a or 1b burrows. If the soils are deeper with a heavier clay component (where the soils are predominantly white), the species can be collected from type 3 burrows (which exhibit the typical characteristics of fan-shaped chimneys, multiple juvenile openings and large chambers beneath the surface).
