Pachyrhynchus barsevskisi Rukmane, 2016

This distributional map is inspired by one article published in 2016. See references.

Comments on Locality Data

The paper indicated that the collection done in October 2015 in Sierra Madre was in "Disimongal, Madela." There is no such place as Madela in the province of Quirino. However, there is a municipality called Maddela, and in this municipality there is a barangay called Disimongal. It is possible that the name of the place is just misspelled in the paper. The paper also indicated that another collection was done in May 2015 in the province of Quirino. However, the barangay was not specified. This may mean collection could be in the same barangay (Disimongal), but it is not known.

The same case can be observed on the locality for the holotype where only up to the municipality level was indicated (Province of Aurora, Municiplity of Dingalan). No GPS coordinates were indicated in the paper for this particular species. The seemingly inadequate knowledge of Philippine geography probably means that the researcher may not have visited the sites where collection was done. If so, it would have been better if the researcher actually went to the Sierra Madre mountain range to ensure appropriate acquisition of GPS coordinates and proper identification of the locality up to the barangay (and possibly purok) level.

The paper also indicated collector as "local collector". It would have been more appropriate to indicate the name of the collector for credibility and reliability. Collection of wildlife for research purposes is approved through the issuance of Wildlife Gratuitous Permit (WGP) by the Department of Environment and Natural Resources (DENR) Regional Office. This is under Republic Act 9147, also known as the "Wildlife Resources Conservation and Protection Act". But since the month and year of collection was indicated in the paper, the name of such local collector is probably in the permit that the DENR keeps in file, and can be retrieved by a simple "Freedom of Information" request.

Also, for research involving collection of actual specimens, Section 4.1 in the Wildlife Gratuitous Permit indicates that the DENR shall be acknowledged. Such acknowledgment is not indicated in the paper.

[Main] The Wildlife Resources Conservation and Protection Act (RA 9147) together with its Implementing Rules and Regulations (IRR) and Bioprospecting Guidelines present the requirements in performing wildlife collections. A few sections of the DAO 2019-09 and RA 9147 are highlighted here to emphasize the importance of keeping up to date with the existing laws for the conservation of Philippine wildlife. Aside from species that are declared critically endangered, endangered, or vulnerable, other threatened species are explicitly defined and protected. [DAO 2019-09] Section 1(e.4). Definition of Terms, Other Threatened Species "Refers to a species that is not critically endangered, endangered nor vulnerable but is under threat from adverse factors, such as over collection throughout its range and is likely to be moved to the vulnerable category in the near future.  It also includes species that have the tendency to become threatened due to predation, destruction of h
