Rana Nodriza Inesperada (Jaramillo-Martinez, Vilà, Guayasamin, Gagliardi-Urrutia, Rojas-Runjaic, Simões, Chaparro, Aguilar-Manihuari, and Castroviejo-Fisher, 2025, Bull. Am. Mus. Nat. Hist., 471: 20). 

Distribution

Geographic Occurrence

Natural Resident: Colombia, Ecuador

Comment

In the Colostethus trilineatus group, and previously confused with Colostethus marchesianus (now Allobates marchesianus), according to the original publication. Venegas and Gagliardi-Urrutia, 2013, in Pitman et al. (eds.), Rapid Biol. Social Invent. Rep. 25: 112, reported the species from Peru. Medina-Rangel, Thompson, Ruiz-Valderrama, Fajardo Muñoz, Lombana Lugo, Londoño-Guarnizo, Moquena Carbajal, Ríos Rosero, Sánchez Pamo, and Sánchez, 2019, in Pitman et al. (eds.), Bajo Caguán–Caquetá, Rapid Invent. 30: 400, noted Allobates aff. insperatus from Caquetá, Colombia. Gagliardi-Urrutia, García Dávila, Jaramillo-Martinez, Rojas-Padilla, Rios-Alva, Aguilar-Manihuari, Pérez-Peña, Castroviejo-Fisher, Simões, Estivals, Guillen Huaman, Castro Ruiz, Angulo Chávez, Mariac, Duponchelle, and Renno, 2022, Anf. Loreto: 34–35, provided a brief account and genetic barcode for Allobates aff. insperatus from central Loreto, Peru, now apparently assigned to Allobates juami followin Jaramillo et al. (2025); Allobates liniaureum is only known from the type locality, not sampled by Gagliardi et al. (2022).
