Etymology: Name in apposition. The name is a tribute to Katia Cristina Machado Pellegrino, renowned herpetologist and geneticist from Universidade Federal de São Paulo (UNIFESP), for her relevant contribution to lizard cytogenetics and the systematics of Gymnophthalmidae.

Holotype: MZUSP 107623 (field number MTR 19144), from Moiobamba, Purus River (right margin) (4° 43ʹ 37.7″ S, 62° 07ʹ 49.5″ W) municipality of Beruri, state of Amazonas, Brazil. Collected on 11 January 2010 by Miguel Trefaut Rodrigues, Mauro Teixeira Jr, Renato Recoder, Antoine Fouquet, Marco Sena, José Mario Ghellere, Sérgio Marques de Souza and Francisco Dal Vecchio.
Paratypes: Brazil: Amazonas: Campo Tupana: INPA 20302, INPA 20304, INPA 20305; Moiobamba, Purus River (right margin): MTR 19004, MTR 19094, MTR 19172, MTR 19177, MTR 19180, MTR 19365, MTR 19372; Rondônia: Porto Velho (UHE Jirau): MZUSP 103666, MZUSP 103667, MZUSP 103668, MZUSP 100244.
Diagnosis: (i) Femoral pores in females present (0–20 pores, modal value = 14; absent in 27%); (ii) six supralabials (92%), with fourth supralabial being the largest (92%) and third supralabial under the eye (96%); (iii) prefrontal always present; and (iv) hemipenial morphotype 6.
Description of the holotype (Fig. 10): Adult male, with snout–vent length 43.6 mm. Rostral broad, well visible from above, wider than high, contacting the first supralabial, nasal and frontonasal. Frontonasal width two times length, contacting the rostral, nasal, loreal and prefrontals. Prefrontals hexagonal, narrower, contacting each other in the midline, in contact with loreal, first and second supraocular, frontal and frontonasal. Frontal heptagonal, longer than wide, in contact with prefrontals, second supraocular, frontoparietals and contacting interparietal in the midline. Frontoparietals pentagonal, almost the same size as prefrontal, midline not in contact because of contact with frontal, contacting second and third supraocular, parietals and interparietal. Interparietal length two times width, longer and narrower than parietals; in contact with frontal, frontoparietal, parietals and, posteriorly, with the first pair of dorsal scales. Parietals roughly heptagonal, posteriorly rounded, slightly wider than long, in lateral contact with three temporals, anteriorly contacting third supraocular and frontoparietal, posteriorly contacting first dorsals. Three supraoculars: first the smallest; second the largest and in broad contact with frontal; the third superocular is of medium size, in broad contact with frontopariental. Nasal above first supralabial, anteriorly narrowed; nostril in the centre and lower part of the scale; in contact with loreal, frontonasal, frenocular and rostral. Loreal posterior to nasal, narrower and diagonally oriented; posteriorly contacting first superciliar, preocular, ventrally contacting frenocular, anteriorly contacting frontonasal, prefrontals and first supraocular. Frenocular below preocular and loreal, followed posteriorly by a long subocular and sharing suture with preocular, ventrally contacting first and second supralabials and anteriorly contacting nasal. Six supralabials: third the largest, longer than high and under the eye; fifth is higher than long, in posterior contact with two temporals, subocular and sharing suture with postocular; sixth supralabial is the smallest, contacting granules around tympanum and two temporal scales. Medial region of eyelid with a semitransparent undivided disc surrounded by granular smooth scales. Left lower eyelid with 10 strongly pigmented palpebrals; right one with eight, also strongly pigmented. Four superciliaries: first the largest, wider anteriorly, contacting first and second supraocular, second superciliar, preocular, loreal and eyelid. Temporal region smooth, with scales of different sizes and shapes. Ear opening surrounded by a series of very small and juxtaposed bristly granules; tympanum ovoid and recessed. Lateral surface of neck with smooth, imbricate and larger scales. Head scales smooth and juxtaposed with scattered sensorial organs. Mental broad, width two times length, contacting postmental and first infralabial. Postmental heptagonal, wider than long, length two times mental. Two pairs of chin shields: the first pair very large, occupying more than half of the ventral region of the head, contacting the second, third and fourth infralabials; the second pair much smaller and separated by gulars, in contact with the fifth infralabial. Six infralabials: third the largest; sixth smaller and contacting granules of tympanic region. Eight pairs of smooth, intercalated, imbricate, shielded and rounded gular scales, followed by five distinct interbrachials: three of them larger than gular scales; the external two smaller. Two rows of ventral scales with 19 pairs, from interbrachials (not included) to preanals; between eighth and ninth scale, an incision for tissue sampling. Lateral scales rounded, imbricate, with similar size at mid-body, becoming smaller, numerous, rounded and more imbricate around arm level. Four transverse rows of lateral scales at mid-body. Thirty-one transverse rows of smooth dorsals, imbricate, alternated, hexagonal, wider than long, wider in occipital region and more narrow and acuminate at hindlimb level. A scale in the third row is abnormally divided. A distinctive area with granular scales surrounds the area of arm insertion. The last quarter of the tail is broken; ventral and dorsal scales of the tail are lanceolate, keeled, imbricate, alternated; more rounded near to anal plate. Anal plate with five lanceolate scales: medial and paramedial the largest; medial one recessed, narrower than peripheral scales. Ten continuous femoral pores on each leg, preanal pores present, each pore within a small and rounded scale on the ventral surface of hindlimbs. Left hemipenis removed. Forelimbs with large, smooth and imbricate scales; those on ventral part of brachium much smaller and rounded. Anterior and ventral parts of hindlimbs with large rounded smooth and imbricate scales, identical to the corresponding parts of forelimbs. Posterior part of hindlimbs with irregular granules, grading progressively to larger imbricate scales on dorsal part of tibia. Metacarpal and metatarsal scales imbricate and larger than phalangeal scales; supradigital lamellae smooth and imbricate. Palmar and plantar surfaces with small granules; right palmar surface with 13 single infradigitals on finger IV and left palmar surface with 12 infradigitals on finger IV; 16 double infradigitals on toe IV. Toes and fingers, except for finger I, clawed, and in the following relative sizes: I <II <V <III <IV.
Coloration in preservative: Dorsal, tail and lateral surfaces of body dark brown, with darker stains on anterior portion of dorsal and lateral scales and irregularly distributed on the tail scales. Small sparse stains on the head. Flanks predominantly dark brown from the nasal to the hindlimbs, becoming more yellowish to cream on the ventral part of the body and tail. Ventral parts of body and tail immaculate creamy.
Measurements of holotype (in millimetres): SVL 43.6; TRL 25.5; HL 8.7; HW 6.4.
Sexual dimorphism and variation: Iphisa pellegrino is sexually dimorphic. Males have a larger head than females (ANCOVA, F 1,14 = 7, P <.01). Males have more femoral pores than females (Kruskal– Wallis, Χ 2 = 10.8, P <.01, mean = 19 and 9, respectively). Females have more dorsals and ventrals than males (Kruskal– Wallis, Χ 2 = 7.7, P <.05). Only two individuals (MZUSP 103666 and 103668) from the municipality of Porto Velho, in the Hydroelectric Plant of Jirau, an area where populations of I. elegans and I. pellegrino co-occur, have seven supralabials.
Distribution: Iphisa pellegrino has a restricted distribution, occurring in central Amazonia (purple in Fig. 2), south of the Amazon River, only in the interfluvium of the Purus–Madeira Rivers.
