Description of the advertisement call of Phasmahyla spectabilis Cruz, Feio & Nascimento, 2008 (Anura: Phyllomedusinae) with comments on its distribution and reproduction
In this study we describe for the first time the advertisement call of Phasmahyla spectabilis (Fig. 1) and provide new data on the geographical distribution and reproduction of the frog. Species belonging to the genus Phasmahyla Cruz (1990) are found in mountain streams in the Atlantic Rainforest from the states of Paraná northwards to Bahia (Cruz et al. 2008a), wherein seven species are currently recognized: P. guttata (Lutz), P. cochranae (Bokermann), P. jandaia (Bokermann & Sazima), P. exilis (Cruz), P. spectabilis Cruz, Feio & Nascimento, P. timbo Cruz, Napoli & Fonseca and P. cruzi Carvalho-e-Silva, Silva & Carvalho-e-Silva. Main characteristics of the genus are the absence of an external vocal sac, cream iris and tadpoles with an oral disc modified into a short funnel-shaped structure (Cruz 1990) (Fig. 1D). All members of the genus show highly specialized reproductive strategies by laying their eggs outside the water in nests built up with enrolled leaves (Cruz 1990). Subsequently, hatching tadpoles drop into lotic water, where they feed until they complete their metamorphosis (mode 25 sensu Haddad & Prado 2005). Phasmahyla spectabilis has already been included in the red list category “data deficient” (Angulo 2009).
