Amphibulima

Three species of Amphibulima have been reported from Dominica, of which the local subspecies of A. patula is the most frequently encountered. The two others, A. pardalina and A. browni Pilsbry, 1899 are much rarer. The latter is here pictured, thanks to David Robinson (yes, him again :-)

Seeming-slug or semi-slug

Several months ago I showed some pictures of a semi-slug that remained puzzling at that time. With the help of David Robinson we reached the conclusion that it must have been a juvenile of Amphibulima pardalina Guppy, 1868. The poor snail just happened to have lost his shell and probably didn’t survive his moment of fame before the camera lens...

David sent me the following pictures that convinced me of this ID.
NB: remarkable that there is a light and a dark brown coloured form of this animal.

Thanks again, David!

Today two more pictures of Amphibulima that were very kindly sent by Dr David Robinson. It are juvenile specimens of A. patula from St. Kitts. David writes: “[It] is definitely present on St. Kitts and on Nevis”, islands were it hasn’t been reported from hitherto.

David sent me other pics as well, more on those later.

Update on Dominican Amphibulima

After all those ‘varia’ subjects it’s time to pay attention to Neotropical snails again.

Today I met with Ad Hovestadt, specialist on Antillean snails, to discuss about his recent trip to Dominica. He showed me some Amphibulima shells and suggested that the pictures shown
here are actually Amphibulima patula (Bruguière, 1792), a young specimen. The two other species known from the island - A. pardalina Guppy, 1868 and A. browni Pilsbry, 1899 - have also be collected by him and he gave me an alcohol preserved specimen of the former. This specimen was depicted in this post.
We decided to write on joint paper on these and other species which he collected during his trip.

Ad Hovestadt sent me a picture taken during his recent trip to Dominica, West Indies. Although the background is accidentally sharper than the shell, this is probably a specimen of Amphibulima browni Pilsbry, 1899.

It is one of those rare species that are seldomly collected, so it is fortunate to be pictured.
Thanks Ad!


Update: After examining the shell of this specimen Ad and I have come to the conclusion that it actually represents the very similar A. pardalina Guppy, 1868

Just received some photo's from someone who was in Dominica and hiked high in the mountains there. He took several pictures of snails, one of which is this Amphibulima patula (Bruguière, 1789)
