Explanation of Names
Author of name: Sherman C. Bishop. First year published: 1924.
Okefinokee (the name of the swamp) + -ensis, a Latin ending that means "found at, living in (a place)"
Body length of adult female ~30mm, of adult male ~8mm.(1)
This species is not distinguishable from D. tenebrosus without looking at characteristics of the palp/epigynum (Carico, 1973).
Georgia & Florida according to Carico's revision(2)
, but also Alabama & Louisiana according to the original description by Bishop(1)
Carico (1973) says they are typically collected in swampy areas where they perch vertically on trees. Bishop (1924) says they may stray away from water as in the case of Dolomedes tenebrosus.
Usually aquatic insects but also small fish, tadpoles, frogs, etc.
Adult female D. okefinokensis
may actually be the largest species of Dolomedes
. This rumor is corroborated by the size measurements given in Bishop's original description (females attain 30mm in body length). The next largest is D. tenebrosus
, the adult females reaching up to 26mm in body length.
