A new Tentacle issue is out and here I summarize the Neotropical land snail tids and bits found in there.
Espinosa & Bastardo provide information on the ecology, biology and conservation status of Coloniconcha prima Pilsbry, 1933. They found several populations which seemed healthy, one counting 449 individuals, and observed that this species uses a great variety of vascular plants for feeding and resting. Threats are the construction of (access) roads to crops and agricultural activities, illegal extraction of trees, human induced fires, and the replacement of former shaded coffee crops by short cycle crops like beets.
Fernández et al. report on 51 range-restricted species in the coastal zone of Holguín province, Cuba. They comprise the families Helicinidae (5), Pomatiidae (11), Urocoptidae (5), Cerionidae (21), Oleacinidae (1), Camaenidae [Pleurodontidae] (1), Cepolidae (6), Xanthonychidae (1).
Suárez et al. studied the occurrence and ecology of Cerion mumia hondanum Pilsbry, 1902 near the shore line at Bahia Honda, Cuba. They also report on observations on other species, e.g. they observed how Cerion species deposited their eggs in sand and found one species associated with the mangrove species Rhizophora mangle.
Herrera studied an endemic species of the Cuban Isla de la Juventus (formerly known in older literature as Isle of Pines), Pineria terebra Poey, 1851. This species has two subspecies, each with very small areas of which the habitat is threatened by frequent forest fires.
Cavallari et al. summarize some recent papers which described several new species from Bahia State in Brazil. The diversity in this state seems rather exceptional and may be linked to three biomes being present: the Cerrado, the Caatinga and the Atlantic Forest.
Miranda & Pecora analyzed the population structure of both Achatina fulica and the native Megalobulimus paranaguaensis. Their conclusion is that the native snail is possibly most affected by environmental modifications and the efforts to control the African snail.
Agudo-Padron delivered two papers. One recording the first find of Achatina folic in the greater Porto Alegre area, part of the Pampas biome. In the second paper he reports on the malacofauna of Santa Catarina State, which now counts 150 terrestrial taxa. His figure shows some species from the ecological region of Itajai Valley.
Finally, Rodriguez et al. studied the diversity of terrestrial species in 16 municipalities in Rio de Janeiro State in Brazil. The most abundant species are shown in their figure:
