Diagnosis. Differs from Exocnophila hastata comb. nov. by the shorter head and tergum VIII, the slenderer thorax and a slightly narrower cercus with slightly constricted inner margin in males, and the more globose head with more convex vertex, shorter tergum VIII and almost straight margin of tergum X (undulated forming three round lobes in E. hastata ) in females. Differs from Exocnophila ovifuscum sp. nov. by the thicker cerci in both sexes, the less elongate and less compressed head, absence of tubercles in the mesothorax in males, and the less compressed and wider head with a more convex vertex and the almost straight margin of tergum X (irregularly and roundly serrate in Exocnophila ovifuscum sp. nov.) in females. Further differs from females of Exocnophila cornuta by the more robust body, slightly smaller head and less elongated tergum X, and from females of Exocnophila tuberculata by the less robust body and absence of ornamentations on legs.
