Trachysphyrus zaceras Porter

This species, unusual because of its ventro-distally flattened female flagellum, remains known only from the holotype, a specimen labeled “Río Negro, Conesa, CHILE!!, F. H. Walz. ” I assume that it actually comes from General Conesa in the Argentine province of Río Negro, located in austral Subandean Desert between Choele Choel and Viedma along the Río Negro river. There is no similar locality in Chile. Also, T. zaceras has the legs mostly pale orange in color, whereas Chilean members of this species group have the legs largely black .
