Photo of the day (107): Deroceras

Some pictures of an as
yet unidentified slug, probably Deroceras
sp. According to my
colleague Ton de Winter, it is possibly only a form
of Deroceras
laeve (Müller, 1774). Only dissection and
comparison with well-identified material could reveal
their true identity.
The specimens were spotted in Ecuador, Prov. Pichincha, Bellavista. Photographs courtesy of Adrián González.

Deroceras in Argentina
20-07-2010 19:45
In a paper that
appeared some months ago, Martín et al. (2009) give
an overview of the distribution of
Deroceras
reticulatum (Müller, 1774) as alien species in
Argentina. Their overview is based on literature
records and own sampling.
One of their localities is in Prov. Rio Negro, Lago Nahuel Huapi, Isla Victoria. It is mentioned from two other localities in the same region, based on literature records. During a recent visit to Bariloche for the Southern Connection congress, I found the species also south of the lake, near Cerro Otto (41 08’S 71 23’W). It was pictured in this post.
Has the ubiquitous occurrence in this region any link to the frequency of visitors from Europe to this well-known touristic region?

Peruvian slugs

Some weeks ago, Valentín Mogollón sent me some
pictures of slugs that he spotted during a recent
trip to Huancavelica. One clearly was a
Deroceras
species. My colleague Ton de Winter, who is an expert
in slugs, kindly provided his opinion when shown this
photograph:
“Looks like a typical specimen of D. reticulatum (Müller, 1774), but to be sure it is better to look at the anatomy”. Since the specimen was not at hand, I’ll have to be happy with this identification.
At the same trip this specimen was encountered. Doubtless it is a veronicellid, but very hard to be more conclusive than that. Species of this family only can be identified after dissection and some even after additional DNA studies.
There are seven species from different genera known from Peru. I have to confess that I’m not familiar with any of them. So we’ll have to keep this as a Veronicellidae from Huancayo, unless someone steps up with a better idea.
