Body length: PEL: 2.125 mm; APW: 0.875 mm; PPW: 1.825 mm; EW: 2.05 mm; EL: 1.55 mm. This species (Fig. 114) is externally very similar to

. Further differences are found on male genitalia: Eighth sternite (Figs 118-119) is more slender, setae on apex are shorter; eighth sternite and tergite apically more slender (seen from lateral view; compare Figs 48 and 122). The rest of the male genitalia is markedly similar between the two species.

, and it has furthermore been found in a stomach of a bird, it is unlikely that they are conspecific, given the vast geographic stretch between African Sahara and Afghanistan. If it had been consumed by a Kentish plover in Africa and discovered in its stomach in Afghanistan it would have probably passed through the digestive tract of the bird by the time the bird migrated from the Sahara Desert to Afghanistan and would be beneath recognition at best. Instead, given the perfect shape of the insect, I consider it highly probable that the bird consumed it in Afghanistan and thus this species is an element of the Afghan fauna.
