Figs. 19 A–D
Male. Colour. Head dark brown, face light brown. Antenna pale brown. Clypeus yellow, mouthparts pale yellowish. Thorax yellowish, posteromedial part of scutum and scutellum seeming brownish. Legs yellowish, apical fourth of femur 3 slightly infuscated. Wing pale brown; haltere yellow with brown knob. Abdominal tergites pale brown, medially seeming darker brown, sternites yellowish. All setosity pale, yellowish or brownish. Head. Antennal flagellomere 4, Fig. 19 A. 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 10. Thorax. Anepisternum setose, with 56–61 setae; anterior basalare nonsetose; preepisternum 2 non-setose; laterotergite non-setose, episternum 3 setose, with 9–10 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 extending to the level of the tip of R1; wing length 1.6–1.7 mm. Hypopygium. Figs. 19 B–D: Sternite 9 laterally fused with gonocoxa, the posterior margin medially deeply notched, situated near the middle of gonocoxa, anterior margin deeply incised, the setae similar to the adjacent ventral setae of gonocoxa. Ventral mesial margin of gonocoxa angulate, the ventral setae of gonocoxa unmodified; posterolateral part of gonocoxa is drawn into a long lobe, some of its setae arising from small ridges. Parastylar lobe membranous, covered by the mesial margin of gonocoxa, non-setose. No paraapodemal lobe identifiable. Dorsal mesial margin of gonocoxa simple. The setae dorsally on the gonocoxa similar to those on the ventral side. Number of juxtagonostylar setae two, the ventral one is a flattened acute megaseta, the dorsal one a flattened, apically rounded and slightly dilated megaseta with a whip-like branch, both arising from a common very thick basal body which is nearly as long as the megasetae. Anteriorly from the juxtagonostylar megasetae there is a plate-like lobe bearing 1+2 megasetae, the anterior-most larger than the others. Gonostylus deeply bilobed, the lateral lobe with a curved megaseta at apex, the mesial lobe ventrally with 1 long and 5 shorter setae, the dorsal side of gonostylus non-setose. Aedeagus elongate subtriangular, the lateral sides straight, the apex curved ventrad. Hypoproct extending posteriorly just over the base of gonostyli, the number of ventral setae (sternite 10) ca. 25 on each half. Cerci mesially separate.
Female. Unknown.
Discussion. By the non-setose anterior basalare, non-setose laterotergite, sternite 9 fused laterally with the gonocoxa, membranous parastylar lobe, well-developed posterolateral lobe on the gonocoxa, by having 1+2 megasetae anteriorly from the juxtagonostylar megasetae on the dorsal side of the gonostylus and by having a long whip-like branch on the more dorsal juxtagonostylar megasetae Manota virgata resembles especially M. rotundistylus, to a lesser extent M. aristata. It is distinguished from both, as well as from all other Neotropical Manota by a deeply bilobed gonostylus.
Etymology. The name is Latin, virgata, with a twig, referring to the narrow branch on the dorsal juxtagonostylar megasetae.
