| Comment | Synonymy: after Wallach 2016: 279. See this paper also for references. Epictia schneideri presumably represents the new species revealed by the molecular phylogeny of McCranie and Hedges (2016), referred to as E. bakewelli-4 (voucher specimen unknown) in their fig. 2, or an entirely separate discovery if that specimen did not originate from the Sierra Madre del Sur. The two other appar- ently undescribed species, represented as bakewelli-1 (based on mitochondrial genes from UTA 57498 from “between Puerto Escondido and Puerto Angel”) and bakewelli-3 (based on UTA 53657 from “between Mazunte and Piontepanoc”) in fig. 2, originate from coastal localities in Oaxaca. Habitat: pine-oak, deciduous, and semi-evergreen forests Comparisons: see Wallach 2016: 284 for detailed comparisons. |
| Etymology | “This species is named in honor of Greg Schneider, Collections Manager, Division of Reptiles and Amphibians, Museum of Zoology, University of Michigan (UMMZ), and commemorates his 30 years of service to the museum. Greg facilitated my work in Ann Arbor in 1986, and has provided loans, data, and photos on scolecophidians in the UMMZ collections since that time.” (Wallach 2016: 280) |
