The genus Iphisa Gray, 1851 is composed of only one species, Iphisa elegans, distributed in the primary forests of the Amazon Basin of Peru, Ecuador, Bolivia, Colombia, Brazil, and Guiana Shield – Guyana, Surinam (Castoe et al., 2004). In Brazil, the species is known from Amapá, Pará, Amazonas, Acre, Rondônia and Mato Grosso (Ávila-Pires, 1995; Gainsbury and Colli, 2003; Rodrigues et al., 2005; Macedo, Bernarde and Abe, 2008; Vitt et al., 2008; Ávila-Pires et al., 2009; França and Venâncio, 2010; Ávila and Kawashita-Ribeiro, 2011; Marçal, Gomes and Coragem, 2011; Mendes- Pinto and Souza, 2011; Nunes et al., 2012). However, there are still several gaps in the known distribution (Gray, 1851; Dixon, 1974; Duellman, 1978; Ávila- Pires, 1995; Duellman and Salas, 1991; Hoogmoed and Ávila-Pires, 1991; Vitt et al., 2008). Iphisa elegans is a species with diurnal habits, and tends to forage just below the top layer of leaves covering the forest floor (Vitt et al., 2008). In the present note we reported new records of I. elegans (Figure 1) for the state of Mato Grosso, in Central Brazil. On 11 October 2011, two adult specimens of I. elegans were collected in the municipality of Tangará da Serra, state of Mato Grosso, Brazil (14°51’3.78”S, 57°50’11.74”W). The specimens were captured in pitfall traps with drift-fences, installed in forested savanna fragments and riparian forests near the Juba river (collection permit: SUPES/MT 57/2011). The collected specimens were euthanized with injectable anesthetic, fixed in 10% formalin and preserved in alcohol 70%, tissue samples were taken. The specimens were deposited at the Zoological Collection of the Universidade Federal de Goiás (ZUFG), Goiânia, state of Goiás, Brazil (Specimen number: ZUFG 640- 641). The I. elegans specimens from Tangará da Serra municipality fully agree with the diagnosis of Gray (1851) and Dixon (1974). Examination of additional material, previously deposited in the “Coleção Zoológica de Vertebrados da Universidade Federal de Mato Grosso” (UFMT; Cuiabá, Mato Grosso, Brazil) (see Appendix), allowed us to confirm the presence of I. elegans in ten additional localities in north and southwest from state Mato Grosso: municipalities of Colniza ( Parque Estadual Igarapés do Juruena, 8º54’42”S, 59º04’55”W; Estação Ecológica do Rio Roosevelt, Distrito de Panelas, 8º54’11”S, 60º49’22”W), Apiacás (Parque Nacional do Juruena, 9º04’01”S, 57º52’18”W); UHE Apiacás, 9º12’16”S, 57º05’19”W), Cláudia (Fazenda Continental, 11º27’47”S, 54º59’25”W), Sapezal (PCH Cachoeirão, 12º59’48”S, 58º57’29”W), Comodoro (13º48’56”S, 59º41’11” W), Jauru (PCH Ombreiras, 15º06’59”S, 58º43’59”W), Araputanga (PCH Ombreiras, 15º08’05”S, 58º56’43”W), and Reserva do Cabaçal (15º04’48”S, 58º27’57”W) (Figure 2, Table 1). The records of I. elegans for the Mato Grosso state extend its geographic distribution in approximately 125 km east and 311 km southeast of their distributions nearest known (Vale de São Domingos, 15º07’00” S, 58º58’00” W, and Juara, 10°25’46” S, 57°38’16” W, respectively). Notwithstanding, the records from Herpetology Notes, volume 6: 395-400 (2013) (published online on 23 September 2013) New records and updated distribution map of Iphisa elegans Gray, 1851 (Reptilia, Gymnophthalmidae) 1 Centro Tecnológico de Engenharia Ltda., Rua 254, 146, Setor Coimbra, 74.535-440, Goiânia, GO, Brazil; 2 Universidade Federal de Goiás, Instituto de Ciências Biológi- cas, Departamento de Ecologia.
