The species on which a genus is based and with which the genus name remains associated during any taxonomic revision.
〔植,动〕模式种
Example sentencesExamples
Consequently, the species is here proposed to be the type species of a new genus related to Girtyocoelia Cossmann, 1909.
The adult dorsal median septum, seen in the new species, is absent in the type species and dorsal muscle fields are more clearly defined.
However, the ventral valve of Australostrophia mesembria, type species of the genus, is weakly convex, while the dorsal is very gently concave.
These characters alone are insufficient to characterize Schistometopus; thus, the genus is considered nomen dubium and the term is restricted to the type specimen of the type species.
This large group (Clade B) is formed by most of the species of the genus (including the type species, B. rotundifolium), which typically have parallel-veined leaves.
