[Taxacom] word for only species in the genus

[Thomas Pape]

Hi John,

You ask for a term "describing a species that is the sole member of its genus", but that must in my opinion be a property of the genus (i.e., the containing unit) rather than of the item (here = species) being contained.

Also, I am not happy with the term "monotypic" for genera containing only one species, because there is always only one name-bearing type. Better to use "monospecific".

/Thomas

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)." *.
