Morphometric analysis to discriminate between species: The case of the Megalobulimus leucostoma complex

Descripción del Articulo

Plasticity of conchological characters had led to erroneous descriptions and the accumulation of synonyms making difficult the discrimination among species. The land snail genus Megalobulimus is an example of this problem. Megalobulimus leucostoma (Sowerby, 1835) has three subspecies which are diffi...

The land snail genus Megalobulimus is an example of this problem. Megalobulimus leucostoma (Sowerby, 1835) has three subspecies which are difficult to differentiate by using the original descriptions. The aim of this paper is to discriminate among the subspecies of M. leucostoma by using morphometric and distribution analyses. Both provide substantial differences between M. l. leucostoma and M. l lacunosus that would not support the subspecies status of the former. Megalobulimus leucostoma weyrauchi fits into the great conchological variability of M. l .leucostoma; also the sympatric status between these two subspecies would not support the subspecies status of the former, and M. l. weyrauchi should be considered as part of M. l. leucostoma.La plasticidad de los caracteres conquiliológicos ha conllevado a diversas descripciones erróneas y a la acumulación de sinonimias lo cual ha dificultado la discriminación entre especies. El género de moluscos terrestres Megalobulimus es un ejemplo de esta problemática. Dentro de éste se encuentra Megalobulimus leucostoma (Sowerby, 1835), que presenta tres subespecies las cuales no se logran diferenciar correctamente a partir de sus descripciones originales. El presente estudio busca discriminar a las subespecies de Megalobulimus leucostoma a partir del análisis morfométrico y de distribución. Ambos análisis establecen diferencias sustanciales entre M. l. leucostoma y M. l. lacunosus que no soportarían el estatus de subespecie de esta última. Megalobulimus leucostoma weyrauchi se ubica dentro de la gran gama de variabilidad conquiliológica de M. l. leucostoma y sus datos de distribución lo ubican en simpatría con la misma por lo cual su estatus como subespecie no estaría soportado, y podría considerarse como parte de M. l. leucostoma.Universidad Nacional Mayor de San Marcos, Facultad de Ciencias Biológicas2014-08-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/rpb/article/view/981410.15381/rpb.v21i2.9814Revista Peruana de Biología; Vol. 21 Núm. 2 (2014); 117 - 124Revista Peruana de Biología; Vol. 21 No. 2 (2014); 117 - 1241727-99331561-0837reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/rpb/article/view/9814/8640Derechos de autor 2014 Victor Borda, Rina Ramirezhttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/98142020-05-20T19:19:51Z
