Cheliplana caeca Meixner, 1938

The name Cheliplana caeca was used by Meixner (1938) to refer to a species of Cheliplana with strongly curved proboscis hooks and a thick ‘cuticle’ lining the prepharyngeal tube. As noted by Marcus (1952), who refrained from including C. caeca in his key to Karkinorhynchidae, both the male and female genital structures are unknown, making it impossible to identify the species in the future. It is therefore considered a nomen nudum.
