| Popis: | Genus Porocoma Cobb, 1920 Diagnosis (from Gerlach 1962 and Cobb 1920) Xennellidae. Cuticle annulated with longitudinal ridges. Cephalic capsule absent. Secretory excretory pore lies on a setiform elevation. Amphideal fovea horseshoe-shaped. Female reproductive system with two posterior ovaries, one of which extends anterior to vulva and folds posteriorly. Number and structure of male genital branch(es) unknown. Spicules short, arcuate. Tail conicocylindrical. One species. Type species Porocoma striata Cobb, 1920. Remarks This genus was considered closely related to Oxystomina by Wieser (1953), presumably due to the shape and arrangement of the cephalic sensilla, the minute buccal cavity and body shape. Porocoma was included in the Oxystominidae in the classification of Hope & Murphy (1972) but was later moved to the family Xennellidae by Lorenzen (1981) based on similarities with Xennella in the shape and arrangement of cephalic sensilla and presence of longitudinal cuticular ridges.
