 containing very large rhabdites. Testes ventral and prepharyngeal .

 deferentia enter separately into the penis lumen which is not subdivided 

 and opens on the ventral side of the papilla. Common ovovitelline duct 

 opens into posterior part of male atrium. Copulatory bursa rather small, 

 bursal duct initially narrow, widening slightly as it approaches the 

 atrium. Known only from a cave in Virginia. Literature: Hyman (1945).
