The Taxonomy Thread

Given his significance to the subject in question, it is worth noting that Colin Groves has passed away:

Although many disagree with some of his taxonomic opinions, I think we can all agree that he was one of the most influential taxonomists of recent times and made very significant contributions to the fields of taxonomy and biological anthropology.

I am sorry to hear that he has passed away.
 
Some changes to the taxonomy of Japanese salamanders
Zoolog Sci. 2017 Dec;34(6):538-545.
Taxonomic Relationships of Hynobius stejnegeri and H. yatsui, with Description of the Amber-Colored Salamander from Kyushu, Japan (Amphibia: Caudata).

Abstract
Examination of the holotype of Hynobius stejnegeri Dunn, 1923 revealed that the species is identical with H. yatsui Oyama, 1947, recently resurrected from H. naevius (Temminck and Schlegel, 1838). The name H. yatsui is therefore relegated to a subjective junior synonym of H. stejnegeri. The latter name, however, has been widely applied to an amber-colored or tortoise-shell salamander from Kyushu, southwestern Japan, which now requires a new name. We thus describe the amber-colored salamander as a new species Hynobius ikioi. The new species is phylogenetically very close to H. amakusaensis Nishikawa and Matsui, 2014 and H. osumiensis Nishikawa and Matsui, 2014, both also from Kyushu, but is easily distinguished from them by its uniquely bi-colored dorsum.

Slightly off-topic but I'm curious, where are the captive populations of Gracula robusta?

There seems to be a captive breeding programme on Nias Island.

There are some details in this article: Save Magiao: Nias Hill Myna Conservation Breeding Center – Silent Forest and also a few pictures of birds in this breeding centre on the IBC page Nias Hill Myna (Gracula robusta) videos, photos and sound recordings | the Internet Bird Collection | HBW Alive

Interesting to note is that the same places also has Silvery Pigeons Nias Heritage Museum – Critically Endangered Silvery Pigeons discovered at the Museum Zoo
 
Not as many saki monkey species as we thought?

"Reconsidering the taxonomy of the Pithecia irrorata species group (Primates: Pitheciidae)"

Abstract
The number of Pithecia species has considerably increased in recent years. In the first comprehensive taxonomic revision for the genus, five species were recognized, among these, Pithecia irrorata, with two subspecies: P. irrorata irrorata and P. irrorata vanzolinii. These subspecies were elevated to full species in the most recent taxonomic revision of the genus, which was based primarily on pelage color. Additionally, it was proposed that P. irrorata was a group of undescribed species, and three additional species were described from P. irrorata: P. mittermeieri, P. rylandsi, and P. pissinattii. However, diagnoses and geographic distributions are not well defined for the species proposed, bringing confusion to subsequent studies. To address the current hypothesis on the species diversity in the P. irrorata species group, we conducted comparative analyses using the same source of evidence: pelage color variation. Material analyzed includes specimens throughout the distribution of the group in Peru, Bolivia, and Brazil. Based on our results, we recognize two groups that are morphologically diagnosable and correspond to geographically isolated populations. The senior names available for these groups are P. irrorata and P. vanzolinii. We recognize P. mittermeieri, P. rylandsi, and P. pissinattii as junior synonyms of P. irrorata. We also discuss some taxonomic inaccuracies regarding the type localities and type material for the senior and junior names, provide synonymy lists based on extensive literature review, and provide distribution maps for the valid species we recognized.
