Paratypes: USNM 193622, 193624–25, San Martin; Nuevo Tocache. Topotypes: MCZ 126760, La Paz trail, Imparia, Department of Loreto, Peru; UMMZ 68090, Departament of Cochabamba, Bolivia.
Descriptions and measurements of holotype: The scale counts and other characteristics of the I. soinii holotype are in the original description (Dixon 1974) and were confirmed in the specimen by us. Total length 157.0 mm, tail length 105.0 mm (tip regenerated), head length 11.0 mm, head width 7.0 mm, snout length 3.5 mm, axilla–groin length 28.5 mm, leg length 8.2 mm, arm length 5.1 mm, diameter of eye 2.5 mm, diameter of ear 1.0 mm and distance from eye to ear 4.6 mm. The original description matches measurements observed in the holotype.
Diagnosis: (i) Femoral pores in females frequently present (0–16 pores, modal value = 5 and 12; absent in 12.5%); (ii) seven supralabials (91%), with fifth being the largest (95%) and third and fourth supralabial under the eye (95%); (iii) prefrontal usually absent (81%); and (iv) exclusive hemipenial morphotype 5.
Sexual dimorphism and variation: Iphisa soinii is sexually dimorphic, with males having more POR than females (Kruskal– Wallis, Χ 2 = 9.3, P <.01, mean = 18 and 9, respectively). Females have more dorsals and ventrals than males (Kruskal– Wallis, P <.05). Six supralabials are present in only two specimens of I. soinii (UFACF 924 and CORBIDI 11234). Variation in pholidosis is summarized in Table 1.
Distribution: Iphisa soinii is distributed in western Amazonia (red in Fig. 2), in Peru, Ecuador and in Brazil in the forest of lower Moa River and in the Serra do Divisor National Park, Acre state.
Comments: In the last review of the genus Iphisa, Dixon (1974) pointed out that there are no individuals registered at> 700 m a.s.l. However, some of the specimens from Peru occur at higher elevations (CORBIDI 13778, 13920, 16704 and 09940 being obtained at 700, 757, 900 and 1112 m a.s.l., respectively).
