Descriptive notes

VULVA ( Fig. 11G ). Slender, of nearly equal width in both the sagittal and the transverse planes, slightly asymmetric: lateral valve being somewhat higher than mesal one, as well as more densely setose; bursa with a broad and relatively deep median cleft; several, mostly vertically arranged setae on each valve; operculum (op) with narrowly rounded apical margin, exceeding bursa by ca 2 ⁄ 7 of total height of vulva, distally with a dense submarginal row of setae each side. Receptaculum seminis consisting of a long, thin and twisted mesal tube (mt) ending in a lemon-shaped ampula (ma), and a somewhat ticker, nearly straight, lateral tube (lt), not forming an ampulla at bottom.
