Table 3. Selected features of distribution and conservation status of the members of the Tantilla taeniata group. Country distribution abbreviations as follows: Belize = B; Colombia = C; Costa Rica = CR; El Salvador = ES; Guatemala = G; Honduras = H; Mexico = M; Nicaragua = N; Panama = P. Ecological formations are abbreviated as follows: LAF = Lowland Arid Forest, LDF = Lowland Dry Forest, LMF = Lowland Moist Forest, LWF = Lowland Wet Forest, PDF = Premontane Dry Forest, PMF = Premontane Moist Forest, PWF = Premontane Wet Forest, LMDF = Lower Montane Dry Forest, LMMF = Lower Montane Moist Forest, LMWF = Lower Montane West Forest. EVS = Environmental Vulnerability Scores (explained in text). EVS categorization as follows: M = medium; H = high. IUCN categorization as follows: CR = Critically Endangered; EN = Endangered; VU = Vulnerable; LC = Least Concern; DD = Data Deficient; and NE = Not evaluated. Conservation priority levels are explained in the text.

Conservation status. Applying the IUCN Red List criteria (IUCN 2012; IUCN Standards and Petitions Committee 2019) to Tantilla lydia, indicates that this species should be considered Critically Endangered (B1ab[iii]) due to the known distribution being limited to a single highlyintervened, threat-defined area of lowland Coastal Strand habitat of <10 km 2 in total extent, which has undergone extensive loss of remaining habitat due to deforestation and development. Efforts are underway to restore this habitat, and it is likely that further survey work in nearby coastal areas could uncover additional habitat and/or populations. Given the single known locality of Tantilla lydia sp. nov., its unknown population size, unknown extent of geographic and ecological distribution, and significant and continuing degradation of habitat in the vicinity of the type locality, we propose an Environmental Vulnerability Score (EVS) of 16 (6+8+2) within the “High Vulnerability” category (Wilson and McCranie 2003; Johnson et al. 2015).
