The tadpole of the Brazilian torrent frog Hylodes heyeri (Anura; Hylodidae)

摘要

Hylodes heyeri Haddad, Pombal & Bastos is allocated in the H. lateristrigatus group (Heyer, 1982), together with other 17 species. The tadpole of H. heyeri is still unknown and our aim here is to describe the tadpole and compare it with other Hylodesspecies for which tadpole descriptions are available. Thirteen tadpoles in the stage 25 (Gosner 1960) were collected in a torrent stream in Morretes (25 deg 26 min 59 sec S 48 deg 52 min 09 secW), Paraná, south Brazil and PEIC (Parque Estadual Ilha do Cardoso) (25 deg 03 min 05 sec S 47 deg 53 min 48 sec), Sao Paulo, southeast Brazil Voucher tadpoles were deposited at Celio F. B. Haddad collection, Departamento de Zoologia, Universidade Estadual Paulista, Rio Claro, Sao Paulo (CFBH 19248, 21995, 21996). Measurements of morphology follows nomenclature of Altig & McDiarmid (1999) and are reported as mean +- SD, min - max. The dental formula follows Altig (1970). In both Morretes and PEIC there were no other species of Hylodes during our field activities.
