Engaeus fossor
Keith A. CrandallTypes
Lectotype, Zoology Museum, Humboldt University, Berlin 1123 (intersexed); paralectotypes, Zoology Museum, Humboldt University, Berling (intersexed), 1124 (3 intersexed).Distribution
E. fossor has the widest distribution of all endemic Engaeus species in Tasmania. Although the species is found on Hunter Is., it is not present in the extensive collections of freshwater crayfish from King Is.Habitat
E. fossor occupies burrows of type 2 habitats almost exclusively; it has only rarely been found in burrows which are independent of the water-table or in burrows in permanent water. It can be found in habitats of a wide variety of vegetation types. For instance, in the north-west region of Tasmania it is found in the vast swamps dominated by blackwood (Acacia melanoxylon), or in tea-tree swamps associated with small creeks, or in coastal plains (where Geocharax sp. occurs in the permanently wet areas); elsewhere it can be located in buttongrass plains (with Parastacoides sp.), in wet sclerophyll forest or Nothofagus cunninghammi rainforest (for instance at the Lower Gordon River and at the type locality for E. cisternarius).References
