Fig. 13 in New Taxa And Cryptic Species Of Neotropical Snakes (Xenodontinae), With Commentary On Hemipenes As Generic And Specific Characters

Description

Fig. 13. Two unrelated small Brazilian snakes that are similar to Eutrachelophis spp. in nuchal markings and in having 15 dorsal scale rows, but they differ from each other and from Eutrachelophis spp. in fundamental hemipenial and maxillary characters. Color-pattern similarities in these and a few other small snakes include an anterior band or spots (first arrow), followed by paired spots or a fused pale crossbar (second arrow) that is medially constricted like the fused ocelli in some specimens of Eutrachelophis (compare with figs. 2 and 4). A, B. Amnesteophis melanauchen (Jan), a Brazilian
