Issoca assanga

Issoca assanga is a species of land planarian belonging to the subfamily Geoplaninae.

The dorsal side of the body has a yellowish or cream-colored stripe running down the middle, which is divided by a discontinuous, tenuous thin black median line.

At the head region, the color of the body fades into orange, both dorsally and ventrally.

[2] The specific epithet is derived from the Tupi language word assanga, meaning "dense, thick", in reference to the species' apparent cephalic glando-muscular organ.

[2] Issoca assanga has been found within Brazil, in Desengano State Park and the Augusto Ruschi Biological Reserve.
