FIGURE 11. Sulcate (left) and asulcate (right) sides of the hemipenes of Leptophis bolivianus (AMNH 104564) from Estancia Yutiole, department of Beni, Bolivia (A–B); L. coeruleodorsus (TCWC 46262) from municipality of San Fernando de Apure, state of Apure, Venezuela (C–D); L. liocercus (CZGB 1149) from municipality of Ilhéus, state of Bahia, Brazil (E–F). Note that although the hemipenis of CZGB 1149 is slightly bilobed, its sulcus spermaticus remains unbifurcated until the apical portion of the organ; L. nigromarginatus (LPHA 1731) from municipality of Santarém, state of Pará, (G–H); and (TCWC 42177) from Centro Union, departament of Loreto, Peru (I–J). Although the first row of basal spines is small in the four species, the two spines adjacent to sulcus spermaticus are larger than those in other rows. Scale bars = 0.5 cm. Photos by D. Kizirian (A–B) and N.R. Albuquerque (C–J).
