‘ OEDOTHORAX ’ BANKSI STRAND, 1906 INCERTAE SEDIS

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.

Males: Unknown.

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.
