“…However, Leme (1973) elevated all subspecies in Megalobuliminae to species level in an unpublished thesis that largely followed the faunal lists of Morretes (1949Morretes ( , 1953 (Fontenelle et al, 2019). Leme (1973) did not provide a clear rationale for his decision, but was nevertheless followed by later authors (e.g., : Pilsbry, 1901: Pilsbry, -1902Morretes, 1949: 147;Breure. 1979: 63;Richardson, 1995: 79;Salgado & Coelho, 2003: 160;Simone, 2006: 118, fig.…”

Taxonomic study on a collection of terrestrial mollusks from the region of Santa Maria, Rio Grande do Sul state, Brazil

The malacological collection of the Universidade Federal de Santa Maria, curated by Dr. Carla B. Kotzian, has been recently donated to the Museu de Zoologia da Universidade de São Paulo (MZSP, Brazil). The collection is rich in well preserved specimens of terrestrial gastropods from central Rio Grande do Sul state, in southernmost Brazil. That region, centered in the municipality of Santa Maria, represents a transitional area between the Atlantic Rainforest and Pampas biomes and has been scarcely reported in the literature. Therefore, we present a taxonomical study of these specimens, complemented by historical material of the MZSP collection. Overall, we report 20 species, mostly belonging to the Stylommatophora, from which four represent new records for Rio Grande do Sul: Adelopoma brasiliense, Happia vitrina, Macrodontes gargantua, and Cyclodontina corderoi. The present report of C. corderoi is also the first from Brazil. Two introduced species were found in the studied material: Bradybaena similaris and Zonitoides sp.

“…nov. was also described for other species of Megalobulimus, although by three different names; BAKER (1926) referred to it as the "short diverticulum" in M. oblongus, HYLTON-SCOTT (1939), as the "bursa hastae" in M. lorentzianus, and SIMONE & LEME (1998) as the "free oviduct appendix" in M. riopretensis and M. mogianensis. Although this structure was described on each of these species, its function remains unknown (BAKER 1926, HYLTON-SCOTT 1939, LEME 1973, THOMÉ et al 1994. …”

“…Desde entonces se busca incluir las descripciones de la anatomía interna, con énfasis en el sistema reproductor (Leme 1973, 1993, Leme & Indrusiak 1990. Sin embargo, en Colombia no ha sido estudiada la morfología de las partes blandas de los Megalobulimus mencionados.…”

Análisis morfológico del sistema reproductor e identificación molecular a través de los marcadores mitocondriales COI y 16S rRNA de <em>Megalobulimus oblongus</em> (Mollusca, Strophocheilidae) de Colombia

et al. 2014

En este trabajo se hizo el análisis morfológico y molecular a 28 caracoles terrestres de Megalobulimus oblongus, colectados en diferentes departamentos de Colombia, depositados en una colección de referencia. Para la caracterización morfológica, los animales se disecaron al estéreomicroscopio. Se describieron el sistema reproductor y la concha. Del sistema reproductor se tomaron medidas a las estructuras que lo componen. De la concha se describió la forma, el color, el número de espiras y la ornamentación e igualmente se tomaron medidas básicas usando un calibrador digital. Para el análisis molecular se usaron dos marcadores mitocondriales, el 16S rRNA y el gen Citocromo Oxidasa C subunidad I (COI). Ambos marcadores confirmaron la presencia de un único haplotipo en los ejemplares, aun para individuos situados en regiones biogeográficas diferentes y distantes. Este estudio sugiere que en Colombia M. oblongus se encuentra en peligro, por lo que urgen investigaciones sobre reproducción, genética poblacional y biogeografía que esclarezcan su situación en el país. Demuestra además que las colecciones de referencia y los bancos de tejidos son fuentes de información de gran valor, ya que permiten conocer aspectos relacionados con el riesgo en que se encuentran las especies y que sirven de insumo para el diseño de acciones de conservación.
