FIGURE 3 in A multidisciplinary approach reveals a new species of glassfrog from Colombia (Anura: Centrolenidae: Nymphargus)

FIGURE 3. Difference in pectoral musculature among genera of Centrolenidae. A. Diagram of a ventral view for Rulyrana mcdiarmidi (adult male, QCAZ 42049) showing the musculus deltoideus clavicularis (D. c), m. deltoideus episternalis (D. ep), m. supracoracoideus superficialis (Spc. s), m. supracoracoideus profundus (Spc. p), m. pectoralis sternalis (P. es), m. pectoralis abdominalis (P. a) and coracoradialis tendon (Cr. t). B. Detail of humeral muscles of "Centrolene'' acanthidiocephalum, adult male (ICN 5278). C. Teratohyla spinosa, adult male (ICN 19437). D. Nymphargus griffithsi (DHMECN 4164). E. N. pijao sp. nov. adult male (ICN 60228). Note the development of the crista ventralis of the humerus in males of B, C and D (i.e., humeral spine present), and the unnoticed crista ventralis (covered = humeral spine absent) in A and E. Character state codification is indicated in each of the species. Scale bars = 2 mm.
