* "At W-R there are two sheets related to Aganisia lepida: one an illustration (W-R 40662) and the other with two illustrations and a specimen (W-R 40597). All dates agree with the protologue, but the year is one year after the one in the prolologue (1865 vs. 1866). We chose the herbarium specimen W-R 40597 as lectotype."​
