Gongylidium sp. Banks, 1900: 480.
Oedothorax banksi Strand, 1906: 445 (Df).
Type material: Banks’ description (1900) was based on two females collected from Muir Glacier in 1899, but no type designation was mentioned.
Diagnosis:
Females: From original description in Banks (1900): ‘the epigynum is an elliptical area with a nearly square cavity in posterior part; on middle of hind margin is a denticle projecting forward’. Although difficult to comprehend the structure solely based on this description, the presence of a cavity in the posterior part of the epigye discriminates this species from all Oedothorax, Mitrager, Callitrichia species and their related genera, like Gongylidium and Timeticus.
Distribution: USA, Alaska.
Habitat: Glacier. Remarks: Due to the unavailability of type material and any images in the original descriptions of this species, the current status of this species is unclear.
