Manota pedicellata sp.n.

Figs 14 A–F

Male. Colour. Head pale brown, vertex and dorsal part of occiput dark brown. Antenna brown. Mouthparts pale yellowish. Thorax brown, posteromedial part of scutum and scutellum darker brown, ventral part of preepisternum 2 paler brown. Legs pale yellowish, apical third of femur 3 infuscated, traces of slight infuscation at base of F2 and F 3 in some specimens. Wing pale brown; haltere pale brown with dark brown knob. Abdomen brown, sternites paler than tergites. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 14 A. Palpomere 3 of maxillary palpus with apicomesial thumblike extension, with 4–5 apically expanded curved sensilla; palpomere 4 with parasegment, palpomere 5 ca. 1.4–1.5 times longer than palpomere 4. Number of strong postocular setae 9–10. Thorax. Anepisternum setose, with 33–54 setae; anterior basalare non-setose; preepisternum 2 setose, with 12–26 setae; laterotergite non-setose; episternum 3 setose, with ca. 18–25 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 M extending to the level of the tip of R1, wing length 1.7–1.9 mm. Hypopygium, Figs 14 B–F: Sternite 9 about half the length of gonocoxa, lateral margin sharply delimited, posterior margin rounded or transverse, anterior margin deeply incised, the setae similar to the ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple. Parastylar lobe, elongate triangular or slightly sickle-shaped, varying in appearance depending on the angle of view, with 2 setae on the anterior half, the setae arising from prominent basal bodies. Paraapodemal lobe distinct, in Fig. 14 C beyond the parastylar lobe and not visible. Dorsal mesial margin of gonocoxa simple, angularly convex. Dorsal posterior margin simple, posteromesial angle acute, apically rounded, with an aggregation of setae. On the ventral side of the latter there is a finger-like curved lobe bearing two apical setae. Two juxtagonostylar setae present, both rather unmodified pointed subequal megasetae arising from a common basal body, which is slightly longer than the megasetae. Gonostylus about half the length of gonocoxa, semicircular or oval in outline; there is a small apicomesial lobe bearing two rather weak megasetae at apex, the lobe is usually turned to the dorsal side in the mounts and difficult to observe; the ventral setae similar to those on gonocoxa, the lateral and apical setae conspicuously long, the dorsal side of gonostylus non-setose. Aedeagus elongate subtriangular, with or without weak lateral shoulders, the apex curved ventrad. Hypoproct posteriorly extending to the middle of gonostylus, the ventral setae forming a mesial longitudinal stripe of ca. 5 very strong curved setae plus a few weaker straight setae on each half. Cerci medially separate, simple, the setae extending from apex to near the middle, the longest setae nearly as long as the cercus itself and much longer than the gonostylus.

Female unknown.

Discussion. Manota pedicellata belongs to a group of four greatly similar Afrotropical species, also including M. comata , M. petiolata and M. relicina . M. pedicellata differs from the others by lacking a prominent subapical mesial lobe on the gonostylus. The homologous lobe is present but it is small and situated at the extreme apex of the gonostylus. Further, M. pedicellata is distinguished by the ventral setae on the hypoproct, which are in the two rows flanking the apex of the aedeagus: the anterior setae are particularly coarse and claw-like while the posteriors are thin and of usual size. For further discussion, see under M. comata .

Etymology. The name is Latin, pedicellata , bearing a small slender stalk, referring to the long basal body of the juxtagonostylar megasetae.
