Manota prisca sp. n.

Figs 8 A–E

Male. Colour. Head pale brown or yellowish-brown, frons, vertex and dorsal part of occiput darker brown.

Antenna brown, scapus and pedicellus slightly paler brown. Mouthparts pale yellowish. Thorax brown, prothorax, anterior margin of scutum and ventral half of preepisternum 2 pale brown, the intensity of the paler areas varying between specimens. Legs pale yellowish, trochanters 2 and 3 infuscated, basal third of femora 2 and 3 more infuscated with variable intensity. Wing unicolorous greyish-brown; haltere yellowish-brown with dark brown knob. Abdomen brown, sternites 1–4 appearing paler, especially laterally. All the setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 8 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 4–5 apically expanded curved sensilla; palpomere 4 with parasegment. Number of strong postocular setae 11–12. Thorax. Anepisternum setose, with 56–78 setae, anterior basalare non-setose, preepisternum 2 setose, with 20–32 setae, laterotergite non-setose, episternum 3 setose, with 10–24 setae. Wing. Length 1.9–2.6 mm. Hypopygium, Figs 8 B–E: Sternite 9 very large, subquadrangular, about three-fourths of the ventral length of gonocoxa, lateral margin sharply delimited, posterior margin transversely straight, anterior margin shallowly concave, the setae similar to the ventral setae of gonocoxa. Ventral mesial and apical margin of gonocoxa confluent, simple, concave. Parastylar lobe broad, varying much in shape depending on the position, with one or two setae on the mesial side. Paraapodemal lobe distinct, usually partly covered by sternite 9 and parastylar lobe in ventral view. Dorsal mesial margin of gonocoxa rather simple on anterior part, beyond middle with a plate-like lobe bearing numerous strong setae. Dorsal apical margin of gonocoxa with two strong setae arising from a long common basal body. Laterally from the latter with a long flat non-setose lobe. Two juxtagonostylar setae present, one a normal rather small seta, the other a large flat many-lobed megaseta, both the setae arising from a low common basal body. Gonostylus rather long, in dorsal and ventral aspect narrow, in lateral and mesial aspect much broader, setosity on basal parts short, on apical part long, absent on broad ventral and mesial areas, the long mesioventral setae on apical part of gonostylus forming a conspicuous curved row, at the middle of dorsal mesial margin with one megaseta. Aedeagus subtriangular, with lateral shoulders, the apical part curved ventrad. The position of hypoproct varying between the mounts, in some cases extending posteriorly to the basal part of gonostylus, in other cases extending further, up to just over their tips, with ca. 40 evenly distributed setae on each half. Cerci mesially separate.

Female unknown.

Discussion. M. prisca is not similar to any other described Manota . It is at once distinguished by the long, flat and non-setose apico-lateral lobe on the dorsal side of the gonocoxa, and also by the unique shape and chaetotaxy of the gonostylus. M. prisca is somewhat reminiscent of those Manota which have a large, broad and anteriorly weakly incised sternite 9, setose plate-like-lobe at the dorsal mesial margin of gonocoxa and a large hypoproct, e.g. M. obtecta ( Fig. 7 B), but differs by having the lateral margin of sternite 9 free, not fused with the gonocoxa.

Etymology. The name is from Latin, prisca , of former times or ancient, and refers to the primitive impression given by the fly with its large sternite 9, which is not fused with the gonocoxa laterally.
