Species Clarification

[ArachnoSoldier]

Just a quick thread... I know that many new species are found, and there has been a few name changes...Lately i've seen the Golden Chaco Knee posted as either Grammostola aurestriata or Grammostola aureostriatum. which is correct?

 

[David Burns]

G.aureostriata

 

[Fierce Deity]

yeah, it's Grammostola aureostriata.

 

[ArachnoSoldier]

and thats the species name that I have been using, but I still see aureostriatum used quite freguently. thanks.

Everybody wants to use anything he think... but to the roots...

Species name gender as a rule (if not species named after smb's name, etc.) must be the same as the gender of the genus...
In this case - Garmmostola is a femine genera name, so the species should be aureostriatA - also a femine...
Is it clear?

I assume you see it spelled differently in classified ads correct? If so then it is likely a result of sellers who don't know the scientific names of what they are selling

To verify correct spelling of scientific names I suggest you visit

Dr. Platnick's World Spider Catalog

or my own The Tarantula Bibliography

As Mikhail explained, in most cases the gender of a specific epithet must match the gender of the genus name. It is not, however, always easy to determine the gender of the genus. For example, the suffix -a often suggests a feminine word and, in the case of Grammostola, the generic name is indeed feminine, thus Grammostola aureostriata or G. rosea. However, although Brachypelma ends with -a its gender is masculine; thus, Brachypelma albopilosum, B. auratum.

Another point: if you know for certain the correct scientific name of one species in a genus and that name expresses gender, you can then be sure of the correct species for another. For example, if you know that Aphonopelma bicoloratum is correct, then if you are uncertain whether it is A. moderata or A. moderatum you can decide that the latter is correct. Or since you know that Haplopelma lividum is correct, you know that the genus is masculine and you can ascertain that H. albostriatum is correct, not H. albostriata.

Hey Michael,

It's neuter, not masculine. I believe we had this discussion before in another thread. Edit-found the thread CLICK HERE...

And I made that exact mistake before, didn't I :wall: ? Doh! Well, I can explain gender declination; I just can't get the sexes right! Fortunately I am in a monogamous relationship and don't have to risk embarrassing error
