Fig. 6 in Integrated evidence sheds light on the taxonomy of the widespread Tantilla melanocephala species complex (Serpentes: Colubridae) and indicates the existence of a new species from southern South America

Fig. 6 Geographical distribution of taxa corresponding to the individuals examined in this study. Stars correspond to types localities of valid species; circles represent the distribution of analyzed individuals; triangles correspond to sequenced samples; crosses and question marks symbolize the type localities of the synonyms of T. melanocephala species; the question marks represent the approximate type locality according to Wilson and Mena (1980). The brown dashed polygon represents the known distribution of the T. melanocephala complex according to Nogueira et al. (2019); the other non-dashed polygons represent the distribution of evolutionary units recognized within the T. melanocephala complex. Acro- nyms of the Brazilian states: AM, Amazonas; PA, Pará; PB, Paraíba; PE, Pernambuco; MT, Mato Grosso; MG, Minas Gerais; SP, São Paulo; PR, Paraná; SC, Santa Catarina; RS, Rio Grande do Sul
