New issue of Tentacle

Robert Cowie and his co-editors have succeeded to publish a new issue of Tentacle, the IUCN/ SSC Newsletter that appears annually. There are several papers in this issue relevant to Neotropical malacology.

Salvador & Simone report on a presumably new Leiostracus species from Minas Gerais, which may be extinct as the small patch of rainforest where it was found a few years ago has been cleared meanwhile. The variation in colour pattern observed in their material is, despite their remark of being “extremely variable”, not uncommon in arboreal species like Leiostracus, Drymaeus and other genera in the superfamily.

Agudo-Padrón & Luz report on a nursery project for Megalobulimus paranaguensis (Pilsbry & Ihering, 1900) in the city of Joinville (Santa Catarina). The first author, in a separate note, also on a salvage effort for a small population of Drymaeus (Mesembrinus) interpunctus (Martens, 1887). In a third note, he draws attention to the precarious official conservation status for mollusks in the States of Santa Catarina and Rio Grande do Sul, Brazil.

Suarez & Martínez report on the finding of a new population of Cerion tridentatum rocai Clench & Aguayo, 1953, on the Itabo River bank, in Boca Ciega, Havana, Cuba, approximately 4 km west of the type locality.

Fernández et al. provide data on rock dwelling species at risk due to recreational developments in Holguín, Cuba. Given the recent political changes this risk may turn out to devastate other snail populations along the Cuban coast in the time to come.

Simone draws attention to the recently described Adelopoma species from a park in Sao Paulo (see also here).

In three separate notes, Herrera reports on snails from the Island of Youth, Cuba (= Isla de la Juventus, formerly Isla de Pinas). One with a new locality record for a colour variation of Liguus fasciatus, one with a new locality for Priotrochatella stellata, and the last one on conservation issues in the Sierra de las Casas.

Santos and a suite of co-authors finally devote two pages on their efforts to update the list of endangered non-marine molluscs in Brazil. The new list features eight land snail species.

Comparing these papers with previous issues, it may be noted that the diversity of authors and topics (Brazilian and Cuban land snails) is diminishing. The complete issue is available online at: http://www.hawaii.edu/cowielab/Tentacle/Tentacle_23.pdf
