Tribe Heterandriini + Tribe Gambusiini + Supertribe Poeciliini

[Clade 122]

Diagnosis. Members of this clade can be diagnosed by the following not uniquely derived and/or reversed features: (1) anterior margin of frontals extend anterior by between nasals [1-0]; (2) posterior supraorbital canal (2b, 3, 4a) absent or opened, forming a shallow groove [5-0]; (3) third gonapophysis forming an angle of 10-32 degrees relative to vertebral column [55-2*]; (4) first proximal radial of dorsal fin in adult males located between neural spines of 13 th and 14 th vertebrae [62-1]; and (5) hypural plate partially fused with an elongate aperture [131-1].

Tribe Heterandriini Hubbs , new usage [Clade 54]

Heterandriini Hubbs, 1924: 7 . Type-genus: Heterandria Agassiz, 1853 .

Diagnosis. Heterandriins share the following uniquely derived and unreversed feature: (1) distal portion of third and fourth gonactinosts completely fused, except by a small notch [74-3*]. Heterandriins can also be diagnosed by the following not uniquely derived and/or reversed features: (1) epiotic process shorter than exoccipital process [3-2]; (2) anterior process of anterior ceratohyal extending ventral to ventral hypohyal present [24-0]; (3) dorsolateral process of pelvic fin in adult males large [36-1]; (4) width of first pelvic-fin ray in adult males decreasing abruptly at distal portion, distal slender portion long [41-1]; (5) first proximal radial of dorsal fin in adult males located between neural spines of 11 th and 12 th vertebrae [62-6]; (6) absence of a basal process on first gonactinost [69-0]; (7) distal portion of second and third anal-fin gonactinosts fused [71-1]; (8) membranous tip anterior to R4 and R5 curved downwards [110- 1]; (9) membranous tip anterior to R4 and R5 small [111-1]; and (10) dorsal expansion of ray 5p of anal fin in adult males present [124-1].
