[Clade 113]

Diagnosis. Members of this clade can be diagnosed by the following not uniquely derived and/or reversed features: (1) parietals short restricted to the epiotic region, not reaching sphenotic anteriorly [2-1]; (2) epiotic process long extending beyond first pleural rib [3-0]; (3) ascending process of parasphenoids in adults long, contacting pterosphenoids [20- 0]; (4) first proximal radial of dorsal fin in adult males located between neural spines of 10 th and 11 th vertebrae [62-4]; (5) adult females with first proximal radial of dorsal fin located between neural arches of 10 th and 11 th vertebrae [63-2]; (6) absence of a basal process on first gonactinost [69-0]; (7) complete fusion of second and third gonactinosts [72-1]; (8) lateral process on base of fifth middle anal-fin radial in adult males asymmetrical [79-3]; (9) middle anal-fin radials 5, 6, and 7 in adult males asymmetrical (right lateral projection more compressed and much larger than left one) [80-1]; (10) anal fin asymmetrical in adult males [87-1]; (11) more distal elements of R6 branches partially fused [127-1]; and (12) hypural plate bipartite [131-2].
