Anomaloglossus praderioi was originally described as Colostethus praderioi by E. La Marca in 1998 on the basis of two male specimens. The present paper provides a redescription of the species on the basis of new material from Maringma Tepui in Guyana and an additional specimen from Sierra de Lema in Venezuela. The redescription includes descriptions of the tadpole and vocalisation. Anomaloglossus praderioi is a medium-sized species mainly distinguished from its known congeners in having Fingers I, II and IV equal in length, the tip of Finger IV barely reaching the base of the distal subarticular tubercle on Finger III when fingers are adpressed, Fingers II and III with preaxial keel-like lateral folds, toes basally webbed with folded flaplike fringing except on Toes IV-V, symmetrical cloacal tubercles present, thin pale dorsolateral stripe present from tip of snout to tip of urostyle, ventrolateral stripe inconspicuous, never straight, oblique lateral stripe absent, throat in male grey to very dark grey, almost solid black, with black blotches, throat in female bright orange, almost immaculate. The tadpole is dark brown to black, exotrophic, benthic, LTRF 2(2)/3. The advertisement call consists of long trains of a single note repeated at a rate of 61-76 notes/min with a dominant frequency ranging from 3,562 to 3,856 Hz. The species is reported from eastern Venezuela and western Guyana and inhabits montane medium-canopy forest at elevations between 1,310-1,950 m above sea level.
