Hippa, Heikki, Søli, Geir & Kurina, Olavi, 2019, New data on the genus Manota Williston (Diptera: Mycetophilidae) from Africa, with an updated key to the species, Zootaxa 4652 (3), pp. 401-441 : 420-423

Manota oronnai sp. n.

Figs 9 A–C

Male. Colour. Head light brown, face somewhat paler. Antenna light brown, including scape and pedicel. Clypeus and mouthparts pale yellowish. Thorax yellowish to light brown. Legs yellowish to light brown, apical third of hind femur infuscated. Wing with light brownish tinge because of microtrichia; halter yellowish with blackish knob. Abdomen 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 ca. 1.3 times as long as wide. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 4 apically curved sensilla; palpomere 4 with parasegment. Nine strong postocular setae. Thorax. Anepisternum with 65 setae; anterior basalare and laterotergite nonsetose; preepisternum 2 with 13 setae; metepisternum with 9 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 1.9 mm. Hypopygium ( Figs 9 A–C). Sternite 9 laterally free from gonocoxa, posterior and anterior margins both with deep V-shaped incision medially, extending about middle between bases of gonocoxa and gonostylus, anterior half non-setose, setae on posterior half somewhat shorter than those on ventral side of gonocoxa. Ventral medial margin of gonocoxa angular. Parastylar lobe large, plate-like, triangular, with two setae at medial angle. No paraapodemal lobe identifiable. Dorsal medial margin of gonocoxa simple, convex. Dorsal posterior margin simple, forming together with medial margin a right angled lobe with a dense aggregation of fine setae on medial side. On ventral side of dorsal posterior margin of gonocoxa an elongated, subrectangular lobe, about twice as long as wide, with aggregation of fine setae at apex. One juxtagonostylar setae present, a simple, apically vasculiform megaseta, arising from a basal body, which is longer than the megaseta. Gonostylus subrectangular, apically transverse, with a very long seta deviating from other setosity at apicolateral corner, and with a short finger-like lobe subapically on medial side bearing two weak and simple apical megasetae. Aedeagus subtriangular, with lateral shoulders, apex curved ventrad. Hypoproct extending posteriorly over basal part of gonostylus, the ventral setae (sternite 10) strong and forming a mesial longitudinal stripe of 5–6 setae on each half. Cerci medially separated, setae delimited on the apical and medial margins of cercus.

Female. Unknown.

Etymology. The species is named after the mythical hero Oronna who defended the town Ilaro when it got under the threat of invasion by the Dahomean Army in the 17 th century.

Comments. Because of the non-setose laterotergite, setose preepisternum 2 and gonocoxa posterodorsally with an apical setae bearing lobe, the new species groups together with 16 other Afrotropical species (see couplets 36 to 52 in the Key of the Afrotropical species above). Among them, M. oronnai sp. n. is unique as the lobe posterodorsally from the gonocoxa is subrectangular and with an aggregation of fine setae apically while all other species have this lobe finger-like and with 1–3 strong setae apically. In addition, the new species has a single apically vasculiform juxtagonostylar megaseta, while all other species have two juxtagonostylar setae, which are apically pointed.
