Manota minutula sp. n.

Figs 13 A–E

Male. Colour. Head brown, face a little paler brown. Antenna including scape and pedicel light brown. Clypeus and mouthparts pale yellowish. Thorax brown, ventral part of preepisternum 2 paler brown. Legs yellowish, hind trochanter infuscated. Wing with slightly brownish tinge; haltere yellow with black knob. Abdomen brown. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer ones. Head. Fourth antennal flagellomere 2 times as long as broad. Palpal segment 3 of maxillary palpus with apicomedial thumb-like extension, with three apically curved sensilla; palpomere 4 with parasegment; palpomere 5 about 1.2 times longer than palpomere 4. Nine strong postocular setae. Thorax. Anepisternum with 31 setae; anterior basalare, preepisternum 2 and laterotergite non-setose; metepisternum with 8 setae. Legs. Mid- and hind tibial organs absent. Wing. R1 meeting C within the basal half of the costal margin; the sclerotized part of M2 not extending to the level of the tip of R1; wing length 1.4 mm. Hypopygium. Figs 13 A–E: Sternite 9 laterally fused with gonocoxa, the lateral margin faintly discernible posteriorly, posterolaterally with sclerotized corners, the posterior margin transverse, thin and only faintly visible, extending over the middle between the base of gonocoxa and gonostylus, anterior margin with a wide angular incision, the setae stronger than on the adjacent ventral setae of gonocoxa. Ventral medial margin of gonocoxa simple, forming a large rectangular lobe together with the posterior margin. Posterolateral part of gonocoxa forming a lobe. The ventral setae of gonocoxa unmodified, shorter on medial part than laterally, long on the posterolateral lobe. Parastylar and paraapodemal lobes not identifiable. Dorsal medial margin of gonocoxa simple but with a narrow finger-like lobe with two apical setae at the level of the juxtagonostylar setae. Posteriorly from this there is a short lobe bearing three megasetae with fine seta-like apex. Medioventrally from the dorsal medial margin, and anteriorly from the juxtagonostylar setae two lobes: 1) a large submembranous lobe bearing 1 large unmodified megaseta, and 2) ventrally from the latter a narrower and more sclerotized lobe bearing 2 long blunted megasetae with a small tooth-like megaseta in-between. General setosity on the dorsal side of gonocoxa similar to the ventral one. Two juxtagonostylar setae present, both are flattened megasetae, the more ventral one with long seta-like apex and a tooth-like branch, the more dorsal one with a broad flat apex and with a seta-like branch, both megasetae arising from a common basal body that is longer than the megasetae. Gonostylus elongate subquadrangular, the apicomedial corner with a long and two short setae, the apicolateral corner with one seta that is curved dorsad, at the middle of lateral margin one seta; no other setae on the gonostylus. Aedeagus subtriangular, the apex curved ventrad. Hypoproct extending posteriorly to the middle of gonostyli, the number of ventral setae (sternite 10) ca. 25 on each half. Cerci medially separate.

Female. Unknown.

Discussion. Manota minutula belongs to a group of four species as defined under M. pauloides . Unlike other species in this group, M. minutula has tergite 9 with sclerotized corners posterolaterally and a rather simple subquadrangular gonostylus. For further discussion, see under M. pauloides .

Etymology. The name is Latin, minutula , ‘very small’, referring to the small size of the fly.
