Geoplana vaginuloides is a species of land planarian belonging to the subfamily Geoplaninae.[1] It is found in areas within the Atlantic Forest in the municipalities of Rio de Janeiro and Teresópolis, Brazil.[2]
Description
[edit]Geoplana vaginuloides is a flatworm around 70 mm in length and 4 mm in width. The body is elongate with parallel margins; the front tip is rounded and the back tip is pointed. The dorsal side has a black band running down the middle of the body, flanked on either side by a white-yellow stripe; outside of the yellow stripe is a thin black line, bordered by a reddish-iron colored band. The underlying base color is a saffron yellow. The ventral side is a grey color; at the head, the margins darken.[2]
Aside from its coloration, it is distinguished from other members of Geoplana by having two-layered musculature of the inner pharynx, a developed anteroventral region of the penis bulb, and a penis papilla with the dorsal insertion displaced anteriorly to level the ventral.[2]
