Issoca is a genus of land planarians found in Brazil.
== Description == Species of the genus Issoca are characterized by the presence of a spoon-shaped head having a cephalic retractor muscle, which allows those animals to pull their anterior end upwards and backwards. Associated to the muscle are cephalic glands, forming a so-called cephalic musculo-glandular organ in a way similar to the one found in the genera Choeradoplana and Luteostriata. The copulatory apparatus usually lacks a permanent penis papilla, i. e., the penis is formed during copulation by folds in the male cavity which are pushed outwards.
