Fig. 70 after Kenk (1970b), 



Mature specimens 6-9 ram long and 1.2-1.8 mm wide. Anterior end truncate, 

 with slightly bulging frontal margin and rounded lateral edges, without 

 a neck constriction. Eyeless and unpigmented, white. Body relatively 

 transparent, showing in life the position of the anterior adhesive 

 organ, the pharynx, and in the postpharyngeal part the copulatory complex 

 as a round or elliptical transparent area with an opaque spot in the 

 center. The adhesive organ consists of a deep invagination of the 

 epithelium with irregular outline, which receives the outlets of many 

 eosinophilic glands and to which a system of retractor muscles is 

 attached. Testes numerous, both dorsal and ventral, prepharyngeal . 

 Penis has a large, spherical bulb and a short, finger-shaped papilla. 

 Vasa deferentia enter bulb ventrolaterally and empty separately, but 

 close together, into the elongated, glandular seminal vesicle. From this 

 vesicle a narrower, somewhat curved (contraction?), nonglandular ejacu- 

 latory duct proceeds to the tip of the penis papilla. Genital atrium 

 rather small, receiving the common oviduct in its posterior part. Copu- 

 latory bursa a rounded sac, bursal duct narrow in its anterior portion, 

 gradually widening as it curves down toward the gonopore but showing no 

 histologically distinct vagina nor a terminal sphincter. Found in a cave 

 in Indiana. Literature: Kenk (1970b).
