Several new papers on Neotropical snails did appear recently, with emphasis on Cuba and Brazil (decidedly the most active malacological societies).
Cuban papers were published in a new issue of the journal ‘Solenodon’ and focus mainly on Cerionidae.
Suárez studied the reproductive cycle of Cerion mumia chrysalis Férrusac, 1837. “Gonads of 144 mature specimens of Cerion mumia chrysalis were examined. Between January-December, 2012 were collected 12 specimens per month. Two reproductive cycles were recognized, one from January to April, and another from July to September. Both male and female reproductive cells were observed inside the acini, which defines the species as hermaphrodite. During May-June and subsequently in October-November no follicular activity was observed. In December, the acini decreased notably in size”.
Suárez et al. published on the effect of hurricanes on molluscs. “Data about the conservation status on mollusk populations of Cerion dimidiatum Pfeiffer, C. scalarinum Pfeiffer and Gundlach, C. torrei moralesi Clench and Aguayo, C. p. paucicostatum Torre, and C. orientale Clench and Aguayo, local endemics from Eastern Cuba are given. Populations were affected by the hurricanes hazard, been obtained values of 0.4 ind/m2; 0. 37 ind/m2; 0.04 ind/m2; 0.16 ind/m2 and 0.03 ind/m2 respectively”.
Two papers related to distribution. Fernández et al. (2015a) published on “the geographic distribution range of Cerion saetiae Sánchez Roig, 1948 was widened, with two new records: Playita de Fidel in Saetía key and Baracutey beach from El Ramón de Antilla peninsula. It presence was corroborated at type locality. Abundance and lineal dimensions variability of shell are explained”.
Fernández et al. (2015b) made “a study about terrestrial mollusks in altitudinal levels and different rocky substrata in Sierra de Nipe. Thirty new records from Sierra of Nipe and adjacent heights are presented. Twenty-six localities were visited; among them seven on serpentine rocks between 400-1000 masl, 19 localities on calcareous substratum from 100- 400 masl and eight localities were taking from published papers. One hundred fourteen species were recorded, constituting 8.2% of the Cuban fauna thereby reaching the second more diverse place in Cuba, after Viñales; therefore representing 57.3% of those known species at Nipe-Sagua-Baracoa. On calcareous substratum 113 species were recorded while on serpentine were 25, most of them also on calcareous soils, except Caracolus n. sp. Part of this terrestrial mollusks “hotspot” is protected by the National Park Mensura-Piloto”.
Finally, I like to mention a recent paper by Simone on the bulimulid genus Kora, with description of new species. The abstract reads “Three new species of the recently described genus Kora are described, based on dry material collected in caverniculous and adjacent environments. Kora terrea, from Presidente Olegdrio, MG, is characterized by spotted pigmentation; projected, wide outer lip, and pointed spire. Kora nigra, from Carinhanha, BA, is characterized by dark-brown color, elliptical outline, and rounded, narrow aperture. Kora iracema, from Sao Desidério, BA, is characterized by very ample, projected outer lip, wide spire and white coloration. A new occurrence of the type species, Kora corallina, is reported, from Carinhanha, BA, expanding its geographic distribution ~200km towards southwest. Species of the genus Kora have been shown to be restricted to semi-dry, caatinga environment, restricted to south region of Northeast Brazilian region, and north of Southeast region”.
