Costa HC. Clarifying the type locality of Liotyphlops wilderi (Garman, 1883) (Serpentes, Anomalepididae), with comments on other reptiles from São Cyriaco, Minas Gerais. ZOOSYST EVOL 2022.

Abstract
The snake species Typhlops wilderi (today Liotyphlops wilderi) was described in 1883 based on specimens from São Cyriaco, in Minas Gerais, Brazil. The name of this type locality has been cited in different ways in the literature, making its geographic location confusing. Solving this question is an important issue for future taxonomy and systematic studies. After searching for information on the collector of the type series of L. wilderi (John Casper Branner) using the Google Scholar database, I found that São Cyriaco was a gold mining company located in the current municipality of Alvorada de Minas. Besides elucidating the type locality of L. wilderi, I searched for reptile specimens collected by Branner, deposited in collections registered at the VertNet Portal and SpeciesLink, and personally examined the extant material from Minas Gerais.

Soares YFF, de Aquino PDPU, Bagley JC, Langeani F, Colli GR. Two new species of Hypostomus suckermouth-armoured catfishes (Teleostei: Loricariidae) from central Brazil. JOURNAL OF FISH BIOLOGY 2021; 99:905-920. [PMID: 33959963 DOI: 10.1111/jfb.14777] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 04/29/2021] [Accepted: 05/04/2021] [Indexed: 06/12/2023]
Abstract
This study describes two new endemic Hypostomus species from central Brazil, which were previously identified as genetically distinct lineages in a recent genomic study that recommended their testing and potential description based on morphological data. A machine learning classification procedure (random forest) was used to investigate morphological variation and identify putatively diagnostic characters for these candidate species and revealed that each is morphologically distinct. The new species Hypostomus cafuringa is characterized by small size, dark spots under a light background, deeper caudal peduncle and shorter first ray of the pectoral fin and base of the dorsal fin when compared to congeneric species from the region. H. cafuringa is known from the headwaters of the Maranhão River, upper Tocantins River basin, Distrito Federal, Brazil. The second new species, Hypostomus crulsi, is characterized by dark spots under a light background, absence of plates along the abdomen region, shorter first ray of the pelvic fin, shorter first ray of the pectoral fin and smaller body size. H. crulsi is known from the headwaters of the São Bartolomeu River, upper Paraná River basin, Distrito Federal, Brazil. The rapid conversion of natural habitats for agricultural development and the isolation of protected areas represent a serious threat to the continued existence of these two newly described endemic species, which warrant conservation assessment.
