Manota ghanaensis sp.n.

Figs 11 A–C

Male. Colour. The single specimen seems rather faded. Head brown, face paler brown. Antenna brown. Mouthparts paler yellowish. Thorax brown, preepisternum 2 ventrally paler. Legs pale yellowish, trochanters 2 and 3 brown, apical third of femur 3 infuscated, traces of infuscation at the base of femur 3. 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. 11 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 4 apically expanded curved sensilla; palpomere 4 with parasegment, palpomere 5 ca. 1.4 times longer than palpomere 4. Number of strong postocular setae ca. 11. Thorax. Anepisternum setose, with 31 setae; anterior basalare setose, with 6 setae; preepisternum 2 setose, with 9 setae; laterotergite setose, with 22 setae; episternum 3 setose, with 11 setae. Legs. Mid and hind tibial organs absent. Wing. R1meeting C well on the basal half of the costal margin; the sclerotized part of M2 basally extending to the level of the tip of R1, wing length 1.4 mm. Hypopygium, Figs 11 B, C: Sternite 9 about three fourths of the ventral length of gonocoxa, laterally fused with gonocoxa, posterior margin transverse, anterior margin with medial incision, the setae similar to ventral setae of gonocoxa. Parastylar lobe subtriangular, partly fused with gonocoxa, with 2 setae apically. Paraapodemal lobe not identifiable. Dorsal mesial margin of gonocoxa simple, largely membranous, with a lobe-like widening on posterior half; there is a distinct posterior margin which together with the mesial margin makes an acute angle. At the dorsal mesial margin of gonocoxa, on more ventral level, a plate-like lobe with an aggregation of 10 setae at its posterior margin, the mesialmost of the setae is a normal unmodified seta, the others blunt megasetae. One juxtagonostylar seta present which is a flattened and greatly expanded megaseta arising from a strong basal body which is as long as the megaseta. Gonostylus small, ca. one third of the ventral length of gonocoxa, bilobed with almost equally sized more mesial and more lateral parts, the former with a very strong apical seta, the latter with a few curved apical setae, otherwise the setae are lacking except for a few short ones ventrally. Aedeagus with a broad basal part and narrow apical part separated by distinct lateral shoulders, the apex curved ventrad. Hypoproct large, posteriorly extending as far as the apex of gonostylus, the ventral setae scattered, ca. 30 on each half. Cerci mesially separate, the setae placed at apex, one or two near the middle at the mesial margin, the longest ones about three times longer than the subapical width of cercus.

Female unknown.

Discussion. Manota ghanaensis is very similar to M. toroensis . It is distinguished e.g. as follows: 1) gonostylus is deeply bilobed, with the lobes subequal instead of having the more lateral or dorsal one conspicuously broader, 2) gonocoxa lacks dorsally a posterolateral curved lobe and 3) the aggregation of megasetae on the lobe at the dorsal mesial margin of the gonocoxa has one unmodified seta associated. Also the number of the mentioned setae seems to be higher (10 contra 7–8) in M. ghanaensis . M. ghanaensis and M. toroensis are similar to M. abakiga and M. senticosa . For further discussion, see under these species.

Etymology. The name is derived by the Latin suffix –ensis, denoting place, from the name of the state of Ghana where the type locality is situated.
