Mantella baroni Boulenger

The description is based on a tadpole in Gosner stage 42 from the series of tadpoles catalogued as ZSM 1418/ 2004 (figure 2) (2 tadpoles). Tadpoles were captive bred in 1996–1998 (see Glaw et al. 2000). The examined specimen had the following measurements: BL 7.1 mm, BH 3.7 mm, BW 5.7 mm, TMH 1.8 mm, TMW 1.9 mm, MTH 2.7 mm, TMHM 1.2 mm, ED 1.1 mm, IOD 2.6 mm, IND 1.7 mm, ODW 1.6 mm, TAL 14.8 mm, TL 21.9 mm. The mouth opens anteroventrally. Since all of the tadpoles are already in advanced Gosner stages, the description of the mouth part could not be accomplished. TAL/TL is 68%.

Other tadpoles from the series examined are catalogued as ZSM 1419/2004 (3 tadpoles). All tadpoles were obtained through captive breeding, from parental specimens without precise collecting locality. Variation of all tadpoles is shown in table 6 and 7.
