Larva. Uniformly brown, hairy, with spiny tibiae ( Fig. 61View Plate VII). Eyes bulging; occipital margin slightly concave; antennae short ( Fig. 62View Plate VII). Labium reaching backwards to behind first coxae; labial palp without crenations; 11 pa1pa1 setae with some additional small setae near base; 18 mental setae ( Fig. 63View Plate VII). Femora with two dark cross-bands; tibiae, specially third pair, beset with long spiniform hairs. Wing sheaths surpassing fifth abdominal segment, with long hairs along dorsal keel. Abdomen hairy, but lacking lateral or dorsal spines. Anal pyramid as in Fig. 64View Plate VII.

Measurements. Total length 14.0; greatest width of head 4.5-4.7; hind femur 4.7; hind tibia 6.0-6.2.

Remarks. While searching for frogs in large terrestrial bromeliads, Dr. Helmut Magdefrau from the Bayrische Staatssammlung, Munich (Germany), found the two ultimate instar larvae, each in a separate specimen of bromeliad. Both adults emerged about a week later and stayed alive for two days. Adult male and female look similar, with a pale yellow middorsal stripe along the carina of the black brown mesepisterna, and with an orange abdomen.

Measurements. Total length (incl. anal appendages) 32.5 (♀ 34.5); hind wing 27.0 (♀ 25.5).
