Material: One male and one female from each sampling location, in the collection of J.A. Ott.

Description: With the characters of the genus, measurements see Supporting Information, Table S2 View Table 2 (excel sheet).

The four specimens probably do not belong all to the same species. The male from Dahab is much longer (L> 8 mm) and more slender (a >> 200) than the remaining three individuals ( Figure 16 View Figure 16 ). Its cephalic capsule is short (<60% of corpus length), its subcephalic setae are long (75% of cephalic setae). The enlarged ventral GSO in the post-pharyngeal region protrude as 21 bumps. In contrast the male from Marsa Alam does not show protruding bumps. It shares with both females a shorter body length (L <6 mm), a stouter shape (a <190), a longer cephalic capsule (>70% of corpus length), and shorter subcephalic setae.
