The tadpole of the hylodid frog Hylodes ornatus (Bokermann, 1967), including chondrocranium description, and advertisement call

Abstract

The genus Hylodes Fitzinger is composed of diurnal frogs that live associated to lotic streams in forests (Lingnau et al. 2008; Silva & Benmaman 2008). In Brazil, this genus occurs from the states of Espírito Santo to Rio Grande do Sul (Lingnau et al. 2008; Frost 2011). Hylodes currently comprises 24 species (Frost 2011) distributed in four species groups (Heyer 1982): glaber; lateristrigatus; mertensi; and nasus. Hylodes ornatus (Bokermann) are included in “Hylodes lateristrigatus” species group with other 17 species (Silva & Benmaman 2008; Canedo & Pombal 2007). Fourteen out of 24 species of Hylodes have their larvae described (Pirani et al. 2011).
