Manota patula sp. n.

Figs. 13 A–D

Male. Colour. Head brownish, face paler brown. Antenna pale brownish. Clypeus and mouthparts pale yellowish. Thorax pale brown, medial part of scutum and scutellum seeming darker brown. Legs yellowish, femur 2 weakly and indefinitely infuscated on basal part, femur 3 infuscated on basal and apical fourth. Wing pale greyish brown; haltere yellowish with dark brown knob. Abdominal tergites pale brown, sternites paler than tergites. All setosity pale, yellowish or brownish. Head. Antennal flagellomere 4 seen in ventral view on the slide, lateral view apparently similar to Fig. 4 A ( M. appendiculata ). Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 3 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 ca. 1.2 times longer than palpomere 4. Number of strong postocular setae not possible to count in the single slide. Thorax. Anepisternum setose, with 45 setae; anterior basalare non-setose; preepisternum 2 non-setose; laterotergite non-setose, episternum 3 setose, with ca. 7 setae. Legs. Mid and hind tibial organs absent. Wing. R1 meeting C well on the basal half of the costal margin; the sclerotized part of M2 not reaching to the level of the tip of R1; wing length 1.5 mm. Hypopygium. Figs. 13 A–D: Sternite 9 laterally fused with gonocoxa, the posterior margin short, transverse, not extending quite to the middle of gonocoxa, anterior margin deeply incised, the setae similar to the adjacent ventral setae of gonocoxa. Ventral mesial margin of gonocoxa angled, the ventral setae unmodified; posterolateral part is drawn into a long posteriorly strongly widened lobe. Parastylar lobe membranous, non-setose. No paraapodemal lobe identifiable. Dorsal mesial margin of gonocoxa lobe-like produced mesiad on the posterior half, that part with a prominent row of setae. Otherwise the setae on the dorsal side of gonostylus similar to those on the ventral side. Number of juxtagonostylar setae two, the ventral one a flattened and basally expanded megaseta, the dorsal one a flattened and winding megaseta, both arising from separate basally fused basal bodies which are nearly as long as the megasetae. Anteriorly from the juxtagonostylar megasetae there is a plate-like lobe bearing 4 megasetae at its posterior margin and 1 similar megaseta on its ventral surface. Posteriorly from the juxtagonostylar megasetae there is a narrow transverse lobe bearing 4 setae at apex, one of the setae flattened and stronger than the others. Gonostylus flat, subtriangular, with a transverse lobe at apex, with a crest running from apex to the base of a strong seta on basal half, and with one strong dorsad curved seta at apex. Aedeagus broadly subtriangular, the lateral sides slightly concave, the apex curved ventrad; flanking the aedeagal apodeme there two plate-like structures, the longer posterior one seems striated, the shorter anterior one seems to bear small papillae. Hypoproct extending posteriorly to middle of gonostyli, the number of ventral setae (sternite 10) ca. 25 on each half. Cerci mesially separate.

Female. Unknown.

Discussion. The non-setose anterior basalare, non-setose laterotergite, sternite 9 fused laterally with the gonocoxa, membranous parastylar lobe, well-developed posterolateral lobe of the gonocoxa and the presence of several strong, stout megasetae anteriorly from the juxtagonostylar megasetae on the dorsal side of the gonocoxa make M. patula similar to a number of other Neotropical Manota . However, the species has several unique characters, viz. 1) the pattern of strong megasetae on the plate-like lobe anteriorly from the juxtagonostylar megasetae: 4 in a marginal row, the fifth one on the ventral side of the lobe; 2) apically strongly broadened posterolateral lobe of the gonocoxa; 3) the shape of the gonostylus and 4) the sclerotized structures, of unknown homology, flanking the aedeagal apodeme ( Fig. 13 D).

Etymology. The name is Latin, patula , spread out, referring to the apically expanded posterolateral lobe of the gonocoxa.
