[Taxacom] word for only species in the genus

[John Grehan]

I've had a couple of responses, but they pertain to the genus rather than
the species being the sole member. Perhaps it might help if I show the
sentence as below

"As noted by Viette (1947), the shape of the valva in *Eudalaca *is a
similarity also shared with the Southern Chilean *Blanchardinella
venosus **(Fig.
16)." *Here a comparison is being made between a genus and a single species
of another genus, but that species is the only member of its genus. I was
hoping that there was a technical term denoting that species status.
Otherwise it might seem that the similarity is confined to a single species
whereas there might be other species in that genus that do not share the
similarity.  If there is no such term then I could perhaps just write it as:

"As noted by Viette (1947), the shape of the valva in *Eudalaca *is a
similarity also shared with the monobasic Southern Chilean
*Blanchardinella **(Fig. 16)." *.
