Manota senta sp. n.

Figs. 18 A–E

Male. Colour. Head brown, face yellowish brown. Antenna pale brown. Clypeus yellow, mouthparts pale yellowish. Thorax pale brown, medial part of scutum and scutellum at least seemingly darker brownish. Legs (femur, tibia and tarsus 2 lost) yellowish. Wing pale brown; haltere pale brown, the knob dark brown. Abdominal tergites pale brown, sternites paler yellowish. All setosity pale, yellowish or brownish. Head. Antennal flagellomere 4, Fig. 18 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 3 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 ca. 1.3 times longer than palpomere 4. Number of strong postocular setae 9. Thorax. Anepisternum setose, with ca. 70 setae; anterior basalare non-setose; preepisternum 2 non-setose; laterotergite non-setose, episternum 3 setose, with ca. 10 setae. Legs. Mid tibiae lost in the single specimen; hind tibial organ 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 2.3 mm. Hypopygium. Figs. 18 B–E: Sternite 9 laterally fused with gonocoxa, the posterior margin transverse, medially notched, 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 roundly angled, the ventral setae of gonocoxa unmodified; posterolateral part of gonocoxa is drawn into a long lobe, most of its setae arising from small ridges. Parastylar lobe membranous, covered by the mesial margin of gonocoxa, with 1 seta. No paraapodemal lobe identifiable. Dorsal mesial margin of gonocoxa simple, at the middle poorly discernible. The setae dorsally on the gonocoxa similar to those on the ventral side. Number of juxtagonostylar setae two, the ventral one a flattened, apically pointed megaseta, the dorsal one a flattened apically rounded megaseta with a short twig-like branch, both megasetae are arising from a common basal body which is nearly as long as the megasetae. Anteriorly from the juxtagonostylar megasetae there is a narrow flat lobe apically bearing several fine setae. Anteriorly from this there is a plate-like lobe bearing three strong apically expanded megasetae at its posterior margin and one longer apically not expanded megaseta in more anterior position, the later arising from a separate sub-lobe. Posteriorly from the juxtagonostylar megasetae there is a strong megaseta, which is nearly connected with the mesial margin of gonocoxa. Gonostylus elongate, somewhat sigmoid in outline, with a few setae ventrally on the apical half. Aedeagus elongate subtriangular, the lateral sides almost straight, the apex curved ventrad. Hypoproct extending posteriorly near the middle of gonostyli, the number of ventral setae (sternite 10) ca. 20 on each half. Cerci mesially separate.

Female. Unknown.

Discussion. By its non-setose anterior basalare, non-setose laterotergite, sternite 9 fused laterally with the gonocoxa, membranous parastylar lobe with one seta, well-developed posterolateral lobe on the gonocoxa, by having several strong, stout megasetae anteriorly from the juxtagonostylar megasetae on the dorsal side of the gonocoxa and by having one stout megaseta situated posteriorly from the juxtagonostylar megasetae at the dorsal mesial margin of the gonocoxa Manota senta resembles M. arenalensis Jaschhof & Hippa , M. eximia Jaschhof & Hippa and M. montivaga . It differs from all of them by having 1) a flat lobe with fine apical setae just anterior from the juxtagonostylar megasetae, 2) the megasetae anteriorly from the juxtagonostylar megasetae arranged in a pattern 1+3 instead of 1+4 or 2+3 or in a single group of 5 megasetae, 3) the 3 strong megasetae in the posterior group apically flattened and expanded.

Etymology. The name is Latin, senta , thorny, referring to the many megasetae at the dorsal mesial margin of the gonocoxa.
