The Nomenclatural Acts subsection is missing from the Materials and methods section. The subsection should read as follows: The electronic edition of this article conforms to the requirements of the amended International Code of Zoological Nomenclature, and hence the new names contained herein are available under that Code from the electronic edition of this article. This published work and the nomenclatural acts it contains have been registered in ZooBank, the online registration system for the ICZN. The ZooBank LSIDs (Life Science Identifiers) can be resolved and the associated information viewed through any standard web browser by appending the LSID to the prefix “http://zoobank.org/”. The LSID for this publication is: urn:lsid:zoobank.org:pub:959A2E58-3AD2-46D5-9375-BB2983855EF1. The electronic edition of this work was published in a journal with an ISSN, and has been archived and is available from the following digital repositories: LOCKSS [http://www.lockss.org]; PubMed Central [http://www.ncbi.nlm. nih.gov/pmc].

In the Results and discussion section, the LSID for the new genus and the new species are missing. To ensure their availability, the LSID, names of the new taxa, type designations, and diagnoses are re-declared in this correction. Although without an LSID, the new combination proposed is also re-declared. For detailed descriptions, distributions, etymologies, illustrations, and comments, refer to [1].
