Manota quantula sp. n.

Figs. 17 A–D

Male. Colour. Head dark brown, face light brown. Antenna pale brown. Clypeus pale brown, mouthparts pale yellowish. Thorax yellowish, medial part of scutum and scutellum seeming brownish. Legs yellowish, coxa 2 and coxa 3 posteroapically brown, trochanter 2 and trochanter 3 brown, apical fourth of femur 3 slightly infuscated. Wing pale brown; haltere yellow with dark brown knob. Abdominal tergites pale brown, seeming medially darker, sternites yellow. All setosity pale, yellowish or brownish. Head. Antennal flagellomere 4, Fig. 17 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 5 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 ca. 1.2 times longer than palpomere 4. Number of strong postocular setae 8. Thorax. Anepisternum setose, with 45 setae; anterior basalare setose, with 5 setae; preepisternum 2 non-setose; laterotergite setose, with 13 setae, episternum 3 setose, with 3 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 extending to the level of the tip of R1; wing length 1.8 mm. Hypopygium. Figs. 17 B–D: Sternite 9 laterally fused with gonocoxa, the posterior margin transverse, quite contiguous with the mesial gonocoxal margin, anterior margin shallowly incised, the setae similar to the adjacent ventral setae of gonocoxa; at the posterior margin, between the parastylar lobes, there is a membranous lobe. Posterolaterally the gonocoxa is only slightly drawn into a curved lobe. Parastylar lobe welldeveloped, with 4 setae. No paraapodemal lobe identifiable. Dorsal mesial margin of gonocoxa simple, slightly lobe-like produced mesiad at the middle; the setae on the dorsal side of gonocoxa similar to those on the ventral side. Juxtagonostylar setae not identifiable. Ventrally from the middle of the dorsal mesial margin of the gonocoxa, there is a plate-like lobe bearing posteriorly ca 15 setae some of which are apically sharp, some blunted. Gonostylus flat, broadly oval, with a few setae on the ventral surface, with several stronger setae at mesial apical and lateral areas, the three setae at the apical margin stronger than the others, the mesialmost of these longer than the others. Aedeagus elongate subtriangular, the lateral sides nearly straight, the apex curved ventrad. Hypoproct extending posteriorly over the apices of gonostyli, the number of ventral setae (sternite 10) ca. 20 on each half. Cerci mesially separate.

Female. Unknown.

Discussion. The setose anterior basalare and laterotergite together with sternite 9, which laterally is totally fused with the gonocoxa and which posteriorly extends near the level of the gonostylar bases, group Manota quantula with three other Neotropical species, viz. M. ibabnezi , M. major Jaschhof & Hippa and M. squamulata Jaschhof & Hippa. It differs from all by having the setae/megasetae on the lobe ventrally from the middle of the dorsal mesial margin of the gonocoxa arranged rather in a narrow zone at the posterior margin of the lobe than in a more compact group or patch. Further, M. quantula differs from M. major and M. squamulata by lacking a transverse megaseta posteriorly at the dorsal mesial margin of the gonocoxa and by having the apical setae of the gonostylus short, not nearly as long as the gonostylus. Manota quantula differs from M. ibanesi by having all the setae posteriorly on the dorsal side of the gonocoxa unmodified, in M. ibabnezi there is a seta which is stronger than the others.

Etymology. The name is Latin, quantula , how little, referring to the small size of the fly.
