Figure 14 in Phylogenetic interrelationships, taxonomy, and reductive evolution in the Neotropical electric fish genus Hypopygus (Teleostei, Ostariophysi, Gymnotiformes)

Figure 14. Ventral portion of the gill arches of Hypopygus hoedemani, MZUSP 81488, 47.7 mm TL; dorsal view, anterior to left. Abbreviations: bb, basibranchial; bh, basihyal; cb, ceratobranchial; eb, epibranchial; hb, hypobranchial; ib, infrapharyngobranchial; up, upper pharyngeal tooth-plate. Note the posterior portion of the dorsal surface of the basihyal does not bear a ridge and the lack of ossification of the second to fifth basibranchial. Note also the well-developed pharyngeal teeth on cb5. Right dorsal portion of the gill arches not illustrated.

Figure 2 in Phylogenetic interrelationships, taxonomy, and reductive evolution in the Neotropical electric fish genus Hypopygus (Teleostei, Ostariophysi, Gymnotiformes)

Figure 2. Cleared and stained head of juvenile Brachyhypopomus sp. indet, MCP uncatalogued, 74 mm; left side, lateral view, anterior to left. Upper image shows unmanipulated digital photograph. Lower image is presented as a 'negative', for contrast, with cephalic sensory canal elements highlighted (red) and labeled, and the outline of an unidentified bone, located underneath the antorbital, highlighted (yellow), with no labels. Some of the elements highlighted (red and yellow) are outside the focal plane of the upper image. Abbreviations: aoc, antorbital canal; esc, extrascapular; ioc, infraorbital canal; mc, mandibular canal; nc, nasal laterosensory canal; pac, parietal canal; pasoc, parietal branch of supraorbital canal; poc, preopercular canal; pocl, postotic canal of the lateral line; ptoc, pterotic canal; soc, supraorbital canal.

Figure 1 in Phylogenetic interrelationships, taxonomy, and reductive evolution in the Neotropical electric fish genus Hypopygus (Teleostei, Ostariophysi, Gymnotiformes)

Figure 1. Single most parsimonious phylogenetic tree for Hypopygus, showing the distribution of unambiguous character state transformations. Black rectangles represent reductive characters, and grey rectangles nonreductive characters, with numbers corresponding to character descriptions in the text. Characters marked with the suffix 'R' indicate a reversal of character state. Characters 10–12, 20, 24, 27, 30, and 40 are excluded because they evolve outside clade A. The tree was generated in PAUP* based on the matrix in Appendix 1, rooted a posteriori in the proximate outgroup Steatogenys, and optimized with accelerated transformation optimization (ACCTRAN). Immediate outgroups correspond to Steatogenys (proximate outgroup) and Gymnorhamphichthys + Rhamphichthys (secondary outgroups). Characters 18 and 43 were defined as multistate. Tree length = 54, consistency index = 0.907, and retention index = 0.928, with all branches of zero maximum length collapsed and all characters unordered.
