Abstract
    A new species Cheironchus paravorax n. sp. is described from the oil producing zone of Campeche Sound in the Gulf of Mexico. It closely resembles C. vorax Cobb, 1917 but differs by its more slender habitus, different tail shape with blister, shorter and slightly stouter spicules and finer buccal armature. SEM studies provide additional information on the body cuticle, the head region and buccal armature, and in male on the precloacal supplements and gubernaculum. C. vorax Cobb, 1917 is redescribed based on specimens from the Gulf of Mexico.
