FIGURE 5. Hemipenial morphology of Ninia teresitae (ICN 12527—A) from municipality of Tumaco, Km 28 of the Tumaco–Llorente road, 1 km south of Tumaco, department of Nariño, Colombia; and Ninia atrata (ICN 12529—B) from municipality of San Martin, Vereda La Castañeda, Palmas del Meta S.A, department of Meta, Colombia.
