Mammillonema

Darekar and Khan (1982) described the new genus Mammillonema , with M. mammillatus as its type and unique species, and compared it to Oriverutus , from which it was separated by a series of seriously questionable differences: mammillate papillae, nature of odontophore (“spear extension asymmetrical, zig-zag anteriorly”), both pharyngeal regions nearly equal in length, female genital system didelphic, and mammillate ventromedian supplements. Only the differences observed in odontophore nature might be of some taxonomical relevance, but such a “zig-zag” design has not been described in dorylaims, and is often the result of inadequate killing and fixation processes. Jairajpuri and Ahmad (1992) regarded Mammillonema as identical to Oriverutus and transferred its only and type species to the latter, an action that seems to be well justified and herein accepted.
