Fig. 1 in Phylogenetic analyses and description of a new species of black widow spider of the genus Latrodectus Walckenaer (Araneae, Theridiidae) from Mexico; one or more species?

Fig. 1 (continued on next two pages). Neighbour–Joining (NJ) tree constructed with p distances of CO1 barcode sequences from different specimens and species of Latrodectus Walckenaer, 1805. Colors in the branches indicate species (grey box), yellow branches indicate the new species (L. occidentalis Valdez-Mondragón sp. nov.). Abdomen dorsal and ventral patterns (numbers 1 and 2, respectively) and spermathecae and epigyna (numbers 3 and 4, respectively) of females are shown only for Mexican species. Numbers on branches represent bootstrap support values (> 50% significant). Letters beside the groups are described and discussed in the text.
