Mystropsychoda sp.

Figures 28–30

Diagnose: Duckhouse (1975) characterized the genus by (among others) elongate clypeus and mouthparts, second papal segment shorter than third; thorax without scent organs; subcosta long, connected to R 1 vein; R 5 ends in wing tip. Male terminalia simple symmetrical, aedeagus rounded without porcesses or projections.

Material: 1♂, Beja, Moura, Safara e Santo Aleixo da Restauração , 38°04’40.1”N, 7°14’21.3”W, 207m a.s.l., 15 November 2014, leg. Gonçalves.

Presentation of an incomplete specimen: Head longer than wide without scent organs. Eyes slightly reniform, eye-bridge and interocular suture absent, distance between eyes approximately 12 facet diameters. Antenna incomplete with scape approximately 2x longer than wide, pedicel barrel-shaped, half as long as scape; eight elongate bottle-shaped flagellomeres preserved, with a pair of slightly bent digitate ascoids more than half as long as the flagellomere. Relative length of scape, pedicel and flagellomeres: 40–30–28–28–30–28–30–29–28–27–; absolute length: 0.105–0.079–0.074–0.074–0.079–0.074–0.079–0.076–0.074–0.071– mm. Palpus of four segments, relative length: 44–58–65–73; absolute length: 0.116–0.153– 0.171–0.192 mm; all palpus segments are slightly sclerotized.

Wing length 2.25 mm, width 0.77 mm; length-width ratio 2.91. Sc terminates in R 1, radius and media forks at about same level and basal of middle of wing. R 5 terminates in wing tip, ends of all longitudinal veins with small dark spots, wing membrane hairy.

Thorax without scent organs. Abdomen and terminalia were broken during preparation, however, general appearance of gonocoxites, gonostyli and aedeagus were not very different from other species of this genus described to date, they appeared more elongate and narrower.

Comment: Four species of genus Mystropsychoda Duckhouse are presently known from East and Southeast Africa. This is the first mention outside the Afrotropical region. Features of the head (eye-bridge and interocular suture absent, clypeus and mouthpart elongate), wing venation with Sc connected to R 1, wing membrane hairy, and the shape of the (broken) simple terminalia (aedeagus spoon-shaped), place the specimens clearly in genus Mystropsychoda . Unfortunately, the terminalia were broken during the slide mounting process, therefore the specimen remains unnamed. The terminalia were morphologically not very different from the already described species, gonocoxites, gonostyli and aedeagus narrower and more elongate.
