Fig. 11E

Material examined

BULGARIA • 1 ♀; Belasitsa Mtn , Castanea sativa forest ; 3–10 May 2010; B. Georgiev and H. Delchev leg.; pitfall trap; IBER .

Descriptive notes

Vulva ( Fig. 11E ). Vulva of nearly equal width in both the sagittal and the transverse planes, mostly symmetric; bursa with a deep and rather broad median cleft; evenly setose throughout, without distinct rows; operculum (op) with markedly concave apical margin, exceeding bursa by ca ¼ of total height of vulva, distally with several long setae. Receptaculum seminis consisting of a very long and thin, somewhat bent, mesal tube (mt) ending in a medium-sized, piriform ampula (ma), and a somewhat ticker and mostly straight lateral tube (lt) forming a large, strongly elongate ampulla (la) at bottom.
