Creagrutus, Gunther, 1864

Genus Creagrutus View in CoL .

As mentioned in the preceding node, a test for the monophyly of Creagrutus is beyond the objectives of this paper and this issue was studied in detail by Vari & Harold (2001), who diagnosed this genera supported by 11 synapomorphies. The two species herein analyzed were included in a large polytomy of 41 species of the genus in the hypothesis of Vari & Harold (2001).

Synapomorphies:

1. Longitudinal ridge in quadrate bordering adductor mandibulae muscle ventrally and, to some degree, laterally (152): (0> 1) present. Paralleled in the Iguanodectinae and in node 209. 2. Shape of dentigerous plate of fifth ceratobranchial (204): (1> 0) rounded, with posterior notch. Paralleled in the Iguanodectinae and in Axelrodia lindeae .

3. Articulation between ventral process of mesocoracoid and dorsal margin of scapula (245): (0> 1) present and broad. Paralleled in Gymnocharacinus bergii .

4. Number of unbranched anal-fin rays (285):(1> 0) three or fewer. Paralleled in Iguanodectes geisleri and Paracheirodon axelrodi . 5. Number of ventral procurrent caudal-fin rays (302): (0> 1) 12 or more. Paralleled in the Bryconops clade, in node 229, and in Salminus brasiliensis .
