Type material: Oedothorax seminolus : Holotype: Gainesville, Florida, Gainesville (29°40’ N, 82°18’ W), ♂ 29.xii.1926, coll.W. M, Barrows ( AMNH, examined).

Diagnosis:

Males: This species can be identified by the lack of prosomal modification, the short and wide palpal tibia, and its long, broad, retrolaterally curved, distally rounded and incurved prolateral apophysis, and the embolic division with a direct continuation of the radix and embolus.

Females: Can be identified by the epigyne with a large, convex ventral plate and a deeply and widely emarginated dorsal plate (fig. 10 in Crosby & Bishop, 1936).

Remarks: After examining the type material of Oedothorax seminolus ( Fig. 72 ) and comparing it to the descriptions of Solugas corticarius by Emerton (1909) and Crosby & Bishop (1936), we support the decision of Buckle et al. (2001) that the former is a junior synonym of the latter. Palpal features, such as the lack of membranous connection between radix and embolus, and the shape and position of the embolic membrane, indicate that this species does not belong to Oedothorax as delimited in the present study.
