Etymology

The specific name refers to the Brazilian odonatologist Ângelo B.M. Machado, collector of the type series ( Martínez & Pereira 1967). Pinto (2016) presented an interesting short biography of Ângelo Machado.

Comments

The eight specimens of the type series of C. machadoi are the only known individuals of this species, which is apparently endemic to a ‘ brejo de altitude ’ (Caatinga moist-forest enclave) in the Brazilian state of Pernambuco. However, only five of those specimens were found during this work: three male paratypes housed at the MZSP, and a male and a female paratype at the CMNC. Martínez & Pereira (1967) mentioned the holotype male and allotype female of C. machadoi were deposited at the “author’s collection”, without specifying which of the authors. As said earlier in this work, Martínez’s holotypes and allotypes are nowadays housed at the MACN, while paratypes and ordinary specimens were incorporated to the CMNC via the Henry and Anne Howden collection. In none of them, however, either the holotype or the allotype of C. machadoi is preserved. Therefore, the whereabouts of those two specimens is unknown to us. As for the fifth male paratype, Martínez & Pereira (1967) stated it was deposited in the personal collection of its collector, Ângelo Machado (Belo Horizonte, Minas Gerais, Brazil), and it is probably still housed there.
