Morfología del Epipodio de Prisogaster niger (Mollusca: Vetigastropoda): Revelando Autapomorfías Potenciales de Valor Diagnóstico para Prisogasterinae
Provedor de dados: International Journal of Morphology
Autores: Collado,Gonzalo A; Méndez,Marco A; Brown,Donald I.
En este trabajo se describe la morfología del epipodio del caracol marino Prisogaster niger. En esta especie el epipodio está conformado por un complejo de estructuras entre las cuales los lóbulos del cuello, rebordes epipodiales, tentáculos epipodiales y papilas epipodiales constituyen conspicuos caracteres. El estudio de la morfología del epipodio reveló potenciales autapomorfías de valor diagnóstico para la subfamilia Prisogasterinae.

Microscopic Anatomy of the Reproductive System in Two Sympatric Species of Fissurella Bruguiére, 1789 (Mollusca: Vetigastropoda)
Provedor de dados: International Journal of Morphology
Autores: Collado,Gonzalo A; Brown,Donald I.
This study describes the microscopic anatomy of the reproductive systems of the keyhole limpets Fissurella latimarginata and Fissurella cumingi to test the existence of a possible isolating reproductive mechanism of morphophysiological type between species, and consequently to determine if the findings provide a valid taxonomic characteristic to distinguish these sympatric species. The results show that in both species the reproductive system is intimately associated with the excretory system. The gonad has a septa organization, and is connected with the distal portion of the right kidney by means of a renopericardial duct which functions as a genital duct. The gametes are evacuated to the mantle cavity through the right kidney opening. Besides transport...
