The Bornean ground cuckoo was
described as
Calobates radiceus by the Dutch zoologist
Coenraad Jacob Temminck in 1832 based on a female specimen from
Pontianak district in
Borneo. In 1840, George Robert Gray established it as the
type species of a new genus,
Carpococcyx, because
Calobates was similar to the fly genus
Calobata. Additionally, it is also a
junior homonym of the genus
Calobates, established by the German naturalist
Johann Jacob Kaup in 1829. The
specific name,
radiceus, is either from the
Neo-Latin radius (rod or staff) or
radicis (foundation). It is thought to be an error for
radiatus or
radiosus, with Temminck himself referring to the species by those names in other writings, but the original description does not provide enough evidence to
emend the name. Nevertheless, some authorities use
radiatus as the specific epithet. ==References==
