Trypoxylon 124
Trypoxylon platense Brèthes, 1913:155, ♀, ♂. Syntypes: Argentina: Buenos Aires (MACN). – Richards, 1934:275

Synonymized with Trypoxylon platense by Gemignani, 1940:439. – Bischoff and von Schulthess, 1937:170 (Argentina:
Junca viejo); R. Bohart and Menke, 1976:349 (listed, as questionable synonym of Trypoxylon platense).
