Of these, AMNH 183494 was exchanged to MCZ in July 1928, and AMNH 183500 was exchanged to ANSP in July 1928. The two paratypes from above Baeza are AMNH 176261 and 176262, both sexed as males, collected on 14 and 17 November 1922, by the Olallas. The four paratypes from Baeza are: AMNH 173844, 176263–176265, all males, collected in September and November 1922 .
