With our data set, in which stamen number in Chloranthus was scored as unknown because of the problematical morphology of the lobed androecium, the three stamens of Canrightiopsis are an autapomorphy

Appendices of the midgut are an autapomorphy

Moreover, in Limnogeton fieberi one autapomorphy

The posterior ponticuli is uniquely derived trait (autapomorphy

Neofundulus is distinguished from the remaining genera of Rivulidae family by having the following synapomorphies: fourth pectoral radial not expanded ventrally, a subasal longitudinal white-yellowish stripe on the anal fin in males, transverse black bars on caudal fin of females, and black spots on pectoral fin of males (Costa 19986) Neofundulus splendidus presents very narrow yellow lines on the pectoral fins, instead of black spots present on the other Neofundulus species, thus an autapomorphy
of this species.
In 1985, Chace used this clear species autapomorphy
(presence of hepatic spine) to define a monotypic genus (Kemphyra) and accommodate this species.
