Manota paula sp. n.

Figs. 14 A–D

Male. Colour. Head brown, face yellowish brown. Antenna pale brown. Clypeus yellow, mouthparts pale yellowish. Thorax yellow, medial part of scutum and scutellum at least seemingly darker brownish. Legs yellowish, apical fourth of femur 3 slightly infuscated. Wing pale brown; haltere yellow with light brown knob. Abdominal tergites pale brown, sternites paler yellowish. All setosity pale, yellowish or brownish. Head. Antennal flagellomere 4 similar to Fig. 4 A ( M. appendiculata ). Palpomere 3 of maxillary palpus with apicomesial thumblike extension, with 3 apically curved sensilla; palpomere 4 with parasegment; for palpomere 5, see the comments below. Number of strong postocular setae 8–9. Thorax. Anepisternum setose, with 31–47 setae; anterior basalare non-setose; preepisternum 2 non-setose; laterotergite non-setose, episternum 3 setose, with 7–11 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 1.5–1.7 mm. Hypopygium. Figs. 14 A–D: Sternite 9 laterally fused with gonocoxa except near the posterior margin, the posterior margin transverse, extending well over the middle of gonocoxa, anterior margin deeply incised, the setae similar to the adjacent ventral setae of gonocoxa. Ventral mesial margin of gonocoxa wavy, 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. The setae dorsally on the gonocoxa similar to those on the ventral side. Number of juxtagonostylar setae two, the ventral one a strong megaseta with a wing-like flat lobe near the apex, the dorsal one flattened, with a whip-like branch, both arising from a common basal body which is as long as the megasetae. Anteriorly from the juxtagonostylar megasetae there is a plate-like lobe, anteriorly bearing 2 strong megasetae and posteriorly 2 smaller megasetae. Posteriorly from the juxtagonostylar megasetae there is a small submembranous non-setose lobe and a stronger sclerotized lobe with a couple of normal setae plus a flattened seta at apex. Gonostylus flat, elongate subquadrangular, with a short strong seta at apicolateral corner and a long strong seta plus ca. 4 weaker setae at apicomesial corner. Aedeagus elongate subtriangular, the lateral sides straight, the apex curved ventrad. Hypoproct extending posteriorly to base of gonostyli, the number of ventral setae (sternite 10) ca. 25 on each half. Cerci mesially separate.

Female. Unknown.

Discussion. By 1) non-setose anterior basalare, 2) non-setose laterotergite, 3) sternite 9 fused laterally with the gonocoxa, 4) membranous parastylar lobe with one seta, 5) well-developed posterolateral lobe on the gonocoxa, 5) presence of strong, stout megasetae anteriorly from the juxtagonostylar megasetae on the dorsal side of the gonocoxa, 6) having the two anterior-most ones of the latter in the same position except on different dorsoventral levels, and 7) presence of a small lobe at the dorsal mesial margin of gonocoxa posteriad from the juxtagonostylar megasetae Manota paula is similar to M. acuminata . It differs by having 2+2 megasetae anteriorly from the juxtagonostylar megasetae instead of 2+5 and by having the gonostylus rectangular with apically concave margin instead of gonostylus with wavy margins including a deep apical notch.

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

Comments on type material. The holotype lacks palpal segments 5, therefore ratio of fifth to fourth palpal segment is not presented. Two of the paratypes lack the head and the third paratype is extremely faded.

Types. Holotype. Male, ECUADOR, Nape Prov., Yasuni NP, Yasuni Res. Station, 00°38’ S, 76°36’ W, Malaise trap, 3–20.xi.1998, leg. T. Pape & B. Viklund (on slide, in SMNH). Paratypes. 3 males, with same data as holotype (on slides, in SMNH).
