PARVIDRILUS STRAYERI ERSÉUS, 1999

Amended description: In the light of the atrial appearance, and the preatrial location of the spermatheca in some of the new species, we can now interpret the so-called ‘copulatory organ’ and ‘genital body’ described by Erséus (1999) to be the two atria merging into a common ejaculatory duct and the spermatheca, respectively.

Distribution and habitat: Known only from the type locality in Alabama, USA. Interstitial water. [A subsequent visit to the type locality by C. Erséus and M. J. Wetzel in March 2008 failed to collect additional specimens of P. strayeri for study (M. J. Wetzel, pers. comm.).]
