Manota limai sp. n.

Figs 8 A–E

Male. Colour. Head brown, face somewhat paler. Antenna light brown to brown, including scape and pedicel. Clypeus and mouthparts pale yellowish. Thorax light brown to brown. Legs yellowish, basal and apical fourths of hind femur and basal third of midfemur slightly infuscated. Wing with light brownish tinge because of microtrichia; halter yellowish with blackish knob.Abdomen brown to dark brown, tergites laterally and sternites lighter.All vestiture pale, yellowish or brownish, thicker setae and trichia seeming darker than finer ones. Head. Antennal flagellomere 4 1.1–1.2 times as long as wide. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 5 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 1.5–1.6 times longer than palpomere 4. Nine strong postocular setae. Thorax. Anepisternum with 54–56 setae; anterior basalare and laterotergite non-setose, preepisternum 2 with 18–19 setae; metepisternum with 10–15 setae. Legs. Mid and hind tibial organs absent. Wing. R 1 meeting C within basal half of costal margin; sclerotized part of M 2 not extending to level of tip of R 1; wing length 2.2–2.3 mm. Hypopygium ( Figs 8 A–E). Sternite 9 laterally free from gonocoxa, anterior margin with deep Ushaped incision medially, posterior margin transverse with V-shaped membranous area, extending over the middle between bases of gonocoxa and gonostylus, anterior 1/3 non-setose, setae on posterior 2/3 similar to those on ventral side of gonocoxa. Ventral medial margin of gonocoxa simple, oblique. Parastylar lobe elongate, subquadrangular, covered with conspicuous microtrichia and with 3–4 strong setae at anteromedial corner. Paraapodemal lobe large, apically rounded. Dorsal medial margin of gonocoxa simple. Dorsal posterior margin simple, forming together with medial margin a rounded acute angle with a dense aggregation of fine setae on medial side. Setae on dorsal side of gonocoxa similar to those on ventral side except for a few more prominent ones at posterolateral margin. On the ventral side of dorsal posterior margin (between this and the juxtagonostylar setae), a finger-like lobe bearing a strong apically curved seta at apex. Two juxtagonostylar setae present, one is a rather unmodified long pointed megaseta with a strongly hooked apex, the other an unmodified apically slightly curved megaseta of subequal length, both arising from a common basal body, which is shorter than the megasetae. Gonostylus subrectangular, with posteromedial part drawn out into a prominent rectangular lobe bearing two or three (both the holotype and the paratype are asymmetrical by having 3 megasetae on the left side and 2 on the right) simple, pointed and medially directed megasetae at apical margin, ventral surface of gonostylus setose, dorsal surface with three prominent setae medially, the microtrichia long. Aedeagus subtriangular, without lateral shoulders, apex curved ventrad. Hypoproct extending posteriorly to middle of gonostylus, the ventral setae (sternite 10) strong and forming a mesial longitudinal stripe of 4 setae on each half. Cerci medially separated, subapically constricted, setae confined to apex.

Female. Unknown.

Etymology. The species is named after Dr. Ricardo Faustino de Lima (University of Lisbon, Portugal) in recognition of his contribution in organizing the Malaise trap sampling in São Tomé.

Comments. The non-setose laterotergite, setose preepisternum 2 and a finger like lobe with one apical seta posterodorsally on gonocoxa group Manota limai sp. n. with eight other Afrotropical species, viz. M. issongo , M. joerni , M. mabokeensis , M. dissidens , M. freerki, M. toomasi, M. redunca and M. fuscinula . In having elongated rectangular gonostylus with strong setae or megasetae apically, M. limai resembles M. fuscinula , but can be distinguished in having one of juxtagonostylar megasetae apically hooked (straight or gently curved in M. fuscinula ).

Types. Holotype. Male , SÃO TOMÉ and PRINCIPE, São Tomé, Lagoa Amélia near Bom Sucesso, 00°06°35’27’’E, 29.viii–15.ix.2016, Malaise trap, R. de Lima & L. Viegas leg. (slide mounted, IZBE) . Paratype. Male, same data as holotype, except 15–31.xii.2016 (slide mounted, IZBE) .
