A species complex in the genus Notogynaphallia Ogren and Kawakatsu (Platyhelminthes : Tricladida : Terricola) with a taxonomic revision of homonyms of Geoplana marginata Schultze & Muller and a reinterpretation of Notogynaphallia caissara (Froehlich) anatomy

BELGIAN JOURNAL OF ZOOLOGY, 136(1):81-100.

Three species of Geoplaninae from Southern Brazil with elongated body, parallel margins and yellowish dorsum with five to seven dark longitudinal stripes are studied. The three species, besides Notogynaphallia ceciliae, constitute a complex presenting a long prostatic vesicle, a folded and usually very long male atrium, a female atrium ending in a dorsally or dorso-anteriorly directed diverticulum (vagina), and a long common glandular oviduct approaching dorso-anteriorly. Besides details of the external morphology, the species are mainly differentiated by anatomical characters, such as thickness of the cutaneous musculature (mc : index), position of the ovary as related to first testes, posterior limit of the serial testes, rising of the oviducts as related to the gonopore, site of the efferent duct entrance into the prostatic vesicle, morphology of the prostatic vesicle, and morphology of the male and female atria. Two of the five-striped species were identified, one as Geoplana marginata sensu Graff, and the other as G marginata sensu Marcus, confirming that they are different species. Both are re-defined and re-named, respectively as N. graffi sp. nov. and N. ernesti sp. nov. The third, seven-striped, species was identified as N. abundans and its anatomy is described for the first time.
