Description. The specimen of Bqaatouta is a complete sample but somehow with incomplete antennae and it carries all the diagnostic features of Paleopsychoda jarzembowskii , i. e., eye-bridge incomplete, mouthparts toothed, welldeveloped and of phlebotomine-type, with sharp toothed mandibles and laciniae; maxillary palp four-segmented, with last palpomere twice as long as others and presenting a constriction in its basal third; anterior sub-basal part of costal vein inflated, from either side of end of humeral vein, allowing as such larger surface, with insertions of a basal wing tuft of setae (specific male character); R1 reaching costa beyond level of radial fork; M3 and M4 [CuA1] meeting basally for a very small distance; CuA [CuA2] well-developed, reaching wing margin beyond half of wing; CuP [A] well developed; male genitalia with stylus bearing two apical spines; a specialized long seta strongly curved in its middle part arising between gonocoxite and gonostylus; parameres paired with apically series of four strong setae with incurved apices; surstyli joined basally, bearing apically two strong setae on each. Measurements of the different body parts are very similar to the type specimen, the holotype number 1615A.
