Molecular Characterization of Glossiphonia elegans (Verrill, 1872) (Glossiphoniidae: Hirudinida) from its type locality, West River, New Haven County, Connecticut, USA

Clepsine elegans Verrill, 1872 was described based on material collected from the West River, New Haven, New Haven County, Connecticut, USA (Verrill, 1872). Moore (1901) synonymized C. elegans with the European congener Glossiphonia complanata (Linnaeus, 1758) in view of the morphological similarities of the two species. Subsequently, all North American leeches bearing 6 eyespots and a pair of paramedial lines were considered Glossiphonia complanata. Using specimens collected from Ontario and Michigan, Siddall et al. (2005) resurrected Glossiphonia elgans (Verrill, 1872), because specimens collected from Ontario, Canada and Michigan, USA showed considerable genetic distinction from, and did not form monophyletic group with, European specimens of G. complanata.

Clepsine modesta was described by Verrill (1872) based on specimens collected in the West River and Whitneyville Lake, New Haven County, Connecticut, USA. Consistent with Article 73.2.3 of the International Code of Zoological Nomenclature (Anonymous 1999), the Syntype specimens of C. modesta originated from two localities and thus the type locality encompasses all of the places of origin. Moore (1898) synonomized C. modesta with the European Helobdella stagnalis (Linnaeus 1758) based on similarities in morphology. Subsequently, all North American leeches with a nuchal scute were considered as H. stagnalis with the exception of Helobdella californica Kutschera 1988, known only from Stow Lake, Golden Gate Park, San Francisco, California, USA. In addition to Europe and North America, Helobdella stagnalis has been reported from South America, Africa, and Asia (Sawyer 1986).

mGluRs (metabotropic glutamate receptors) are G-protein-coupled receptors that play an important neuromodulatory role in the brain. Glutamatergic transmission itself plays a fundamental role in the simple nervous system of the model organism Caenorhabditis elegans, but little is known about the contribution made by mGluR signalling. The sequenced genome of C. elegans predicts three distinct genes, mgl-1, mgl-2 and mgl-3 (designated Y4C6A.2). We have used in silico and cDNA analyses to investigate the genes encoding mgls. Our results indicate that mgl genes constitute a gene family made up of three distinct subclasses of receptor. Our transcript analysis highlights potential for complex gene regulation with respect to both expression and splicing. Further, we identify that the predicted proteins encoded by mgls harbour structural motifs that are likely to regulate function. Taken together, this molecular characterization provides a platform to further investigate mGluR function in the model organism C. elegans.
