In a recent paper, Fred
Thompson highlights some Spiraxidae from Costa Rica
and Panama. The subfamilies within this group and
four genera are redescribed; two species are
described as new taxa. New distribution records from
both countries.
The first one is Rectaxis pagodus Thompson, 2010, from La Lola Agricultural station, west of Limón, Costa Rica. Holotype UF 80942. Fig. 1. Scale line = 1 mm.
The second new species is Volutaxis (Volutaxis) eburneus Thompson, 2010. Type locality: Costa Rica, prov. Limón, La Estrella, Hitoy Cerera Biological Reserve. Holotype UF 215409. Fig. 4.

Visitor in the lab

This week the
Systematics
congress is being held in Leiden and Naturalis is a
co-host. Quite some extra visitors this week in our
labs and one of them is Dr Ira Richling (University
of Kiel, Germany). I have been in contact with her
because we share a common fav group: Neotropical
snails.
Ton de Winter and Ira Richling
discussing some Neotropical helicinids.
As a specialist in Helicinidae she was interested to see our small collection. Due to time shortage, she took notes on interesting things and found some alcohol preserved material that she took for further studies.
We also discussed on her observations on Costa Rican Drymaeus. There she observed this genus quite common as a ‘garden snail’, with two species represented on the campus in San José. She found D. sulphureus and D. inusitatus to be blue-bodied. The latter species is restricted to the Caribbean side of the country. These snails are more blue in the lowland, becoming paler higher up in the mountains.
