Heterixalus tricolor (Boettger 1881)

A medium-sized, uniformly colored species of Heterixalus . Males are 23-26 mm in total length, while one female was 28 mm in snout vent length. The back is uniformly colored and looks white in bright sunlight. Females have two black markings above the eyes and two rows of black spots running laterally. These patterns are less distinct in males. Thighs, ventral surface of limbs, hands and feet are orange. Venter is creamish in color. The typical call can be described as "eeep-ep". Two unharmonious note types are present: first type lasts 80-90 ms; second type is shorter, lasting 40-60 ms. Intervals after note type 1 are about 100 ms and notes are arranged in groups, most usually as "1-2" Other combinations are "1-2-2", rarely "1-2-2-2". Frequency ranges from 2.2 to 3.8 kHz.Similar species : Heterixalus madagascariensis lacks the black spots above the eyes and has a different call. H. "variabilis" displays great variability in coloration, but the typical color patterns of H. tricolor females were not found.Taken with permission from Glaw and Vences (2007).
