Abstract The submandibular musculature of 37 species the five currently recognized genera subfamily Phyllomedusinae (Anura: Hylidae) is described; observations are made on variation and ontogeny these muscles. Supplementary apical elements m. intermandibularis occur in all phyllomedusines studied, addition to supplementary posterolateral previously reported. Our discussed context 1) proposed homology between elements; 2) with reported for Pelodryadinae (sister taxon Phyllomedusinae); 3) implications our understanding relationships Pelodryadinae. Anatomical differences their co‐occurrence indicate that not homologous. Despite pelodryadines adhesion fibers principal element occurrence a broad aponeurosis or medial raphe, extensive morphological developmental resemblances structures homologous, presence synapomorphy + J.
