COLOMBIA • 1 adult ♂ ; Santander , municipality of Sucre , La Pradera , Tequendama ; 05°51ʹ47″N , 073°54ʹ40 W , 2574 m a.s.l. ; 23 Jun. 2017 ; Diego Escamilla leg.; UPTC­Am 1012 • 1 adult ♂ ; Santander , municipality of Sucre , La Pradera , Peña Bonita river ; 05°51ʹ43″N , 073°54ʹ16″W , 2574 m a.s.l. ; 20 Aug. 2017 ; Juan Carvajal leg.; UPTC-Am 0972 . Identification. Our specimens were easily identified as H. piceigularis based on: finger webbing extending to base of distal subarticular tubercle of finger IV; ulnar, tarsal and supra-anal folds with red edge, yellow bottom base, and cream top; tympanum covered by skin without modifications; and mental gland present in males (Ruiz­ Carranza and Lynch 1982). Remarks. We recorded 18 individuals, even though the population may be larger, given the auditory record and the capacity of this species for concealment. Hyloscirtus piceigularis was found in the small forest fragment, in a ravine ( Fig. 2B ) and had mossy rocks as their preferred microhabitat ( Fig. 5 ). Animals were active both during the day and at night. Tadpoles at various stages were found in backwaters and other lotic waterbodies during the dry season in February The study area lies between the species’ northernmost occurrence, in the municipality of Encino, and its southernmost occurrence, in the department of Cundinamarca . We extend the distribution of the species approximately 100 km , from the type locality in the municipality of Encino.
