Description

All details followed the original description by Thormar & Sørensen (2010), hence, we would only address two additional points. First of all, we can confirm the absence of glandular cell outlets type 2 in this species. Secondly, we can confirm the presence of female papillae in ventromedial positions on segment 7. They consist of circular openings, and quite broad, sort of rhomboid tubular intracuticular substructures. Tergal extensions of segment 11 are pointed, and extending into long, flexible seta-like tips, formed by a terminal fringe. Sternal extensions are rounded, without any particular fringe differentiation.
