2018 - Azevedo et al. synonymize
Acrepyris, formerly a subgenus containing all the species of
Pristocera in the western hemisphere, with
Pristepyris, which is considered a valid genus separate from
Pristocera. "Recently, when we started a review of '
Acrepyris', we found clearly in part of the publication where the genus
Acrepyris was proposed that
Pristepyris name was already a valid name.
Acrepyris was cited as new genus in Kieffer & Marshall on page 249, published on November 1st 1905, while
Pristepyris was mentioned as a genus already known on page 246 published in the same set pages, referring the designation of
Pristepyris name to the publication of Kieffer (1905). This indicates that
Pristepyris, not
Acrepyris, is the senior synonym for the genus conception."

2014 - "treated in American sources, e.g.
(2)(3) as a subgenus of
Pristocera; according to
(2), no other subgenera are represented in our area; however, Dr Lim have identified some of the posted images as
Pristocera and some as
Acrepyris, so we'll keep both pages as separate genera for the time being." =v=
