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.
