133. Isohypsibius deflexus (Mihelčič, 1960) sensu lato [F]

Terra typica: France (Europe)

Argentina:

• 34°56′S, 58°04′W; 0 m asl: Buenos Aires Province, Arroyo Rodríguez, plankton sample. Rossi & Claps (1991)

Record numbers: Argentina: 1; total: 1.

Remarks: This Argentinean report is the only reference remote from the type locality (France, Europe), and thus it may be incorrect. The original species description reported separation of the claw primary branches from the basal section, suggesting this species belongs to Ramazzottius . A revision of both type material, and the Argentinean sample, is required.
