Material examined

Paratype

OMAN • 1 ♂; Muscat, Azaiba ; 9 Feb. 1989; M.J. Ebejer leg.; NMWC.

Remarks

This is one of a very few species with extensively darkened legs ( Fig. 11A ). It is known only from the type series. Both sexes have a dark band across the frons, dark brown basal flagellomere and brown palpus. The similar species A. nigripes Ebejer, 2016 from Morocco has a yellow palpus, yellow basal flagellomere in the male, a slender postgonite and a differently shaped sternite 6 ( Ebejer 2016: 226, figs 4–6). Aphaniosoma captiosum sp. nov. has the ventro-lateral margin of tergite 6 similar to that in A. nigripes ; it differs from both species in the postgonite, which is thicker and ends in a white seta-like tip ( Fig. 13A ), and in the shape of sternites 5 and 6 ( Fig. 14C ).

Distribution

Oman ( Ebejer 1996).
