Carabidae, Clivinini, Clivina: subgenus Semiclivina move to genus rank?

North American Clivina (Semiclivina) dentipes Dejean would become combination Semiclivina (s. str.) dentipes (Dejean) as a consequence of the proposed taxonomic treatment by Austrian authority Alexander Dostal in ZooKeys 132:33-50 (2011) who elevated subgenus Semiclivina to genus rank. This brings up the question of whether BugGuide should follow the latest peer-reviewed taxonomic revision presented in a single paper by a single author. Other than some recent website endorsements, I am not aware of corroboration for genus rank in a subsequent formal publication other than in 2018 by same Dostal with coauthor Vieira on a "Key to American Clivinini". The main distinguishing character trait of "proepisternum with stridulation stripe" was used to elevate Semiclivina to genus rank. Alexander Dostal is currently the world authority on members of tribe Clivinini. At least within Carabidae, I've sensed slowness by North American workers to accept published genus-subgenus changes across vast waters. Semiclivina is well entrenched as subgenus in recently published works by George Ball & Yves Bousquet (2001- American Beetles), Wolfgang Lorenz (2005 - Nomina Carabidarum), Yves Bousquet (2009 - Zookeys 25:37-48), Terry Erwin (2011 - Treatise Western Hemisphere Caraboidea), and Yves Bousqet (2012 - Catalogue Geadephaga). These authors were already aware of the anatomic character of the proepisternum as grounds for subgenus Semiclivina.

Ultimately, the assigning of rank genus or subgenus is an arbritary/artifical choice and so either is now acceptable in any subsequent presentation of Semiclivina. One must consider the weight of prior usage against the convincing evidence for new usage. As of my update this Jan 05, 2020, I am okay with BugGuide leaving Semiclivina at subgenus rank equally as well as moving it to genus.

I don't see why not
Reasons for generic rank seem reasonable and it is in a published peer-reviewed publication.

Is C. dentipes the only affected taxon in our fauna?

 
Genus Semiclivina in North America
includes S. (S.) dentipes [widespread] and S. (S.) vespertina [AL, LA, MS - introduced].

Please tweak BugGuide accordingly. Thanks.

 
done
thanks, colleagues

 
V - the only change was a genus listing of "Semiclivina"
added to the classification on the Carabidae Info page. No new guide page for genus Semiclivina has yet been created and that is okay with me. See my updated introduction above. Other opinions?
