Manota teocchii Matile, 1972

Figs 27 A–C

Redescription. Male. Colour. Head brown, face paler brown. Antenna brown. Mouthparts paler yellowish. Thorax brown, ventral part of preepisternum 2 paler brown. Legs pale yellowish, apical third of femur 3 infuscated, extreme bases of femur and tibia with traces of infuscation. 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. 27 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 4 apically expanded curved sensilla; palpomere 4 with parasegment, palpomere 5 ca. 1.5 times longer than palpomere 4. Number of strong postocular setae 10 Thorax. Anepisternum setose, with 32 setae; anterior basalare setose, with 8 setae; preepisternum 2 non-setose; laterotergite setose, with 30setae; episternum 3 setose, with ca. 20 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 1.7 mm. Hypopygium, Figs 27 B, C: Sternite 9 large, as long as the ventral part of gonocoxa, anterolaterally fused with gonocoxa, the posterior free part semielliptical, anterior margin with a small medial incision, the setae similar to ventral setae of gonocoxa. Parastylar lobe rather weakly sclerotized, subtriangular, with 2 setae at posterior margin and with rather conspicuous microtrichia. Paraapodemal lobe not identifiable. Dorsal mesial margin of gonocoxa sinuous; dorsal posterior margin angled at the middle, forming together with the lateral margin a large curved setose lobe. At the dorsal mesial margin of gonocoxa, on more ventral level, a plate-like lobe with 2 megasetae at its posterior margin. One juxtagonostylar seta present: a rather unmodified seta arising from a slender basal body, which is as long as the seta. Gonostylus ca. half the ventral length of gonocoxa, apically shallowly bilobed, without prominent strong setae, with rather short unmodified setae ventrally and largely non-setose dorsally. Aedeagus with a shorter subtriangular basal part and narrow longer apical part, without distinct lateral shoulders, the apex curved ventrad. Hypoproct large, posteriorly extending nearly as far as the apex of gonostylus, the ventral setae in two groups, the more anterior one with ca. 40, the more posterior one with ca. 20 scattered setae on each half. Cerci mesially separate, the setae distributed almost to the base of cercus, the longest ones about one and a half times longer than the subapical width of cercus.

Female unknown.

Discussion. Manota teochhii was described including the male hypopygium figured in dorsal aspect by Matile (1972: Fig. 4 ) from the Central African Republic on the male holotype and has not been recorded since. We have not been able to study the holotype and all the details cannot be seen on the original drawing. However, the platelike lobe at the mesial margin of the gonocoxa is well visible and has the same form with the two megasetae placed exactly as in our specimen and there is also a similar aggregation of setae anteriorly. Further, there is a curved setose lobe posterolaterally, which is similar to our specimen and the juxtagonostylar seta, visible in Matile’s illustration on the left side, is a similar unmodified seta as in our specimen. Therefore, we have no doubts about conspecificity of our material.

By its wide sternite 9 which is laterally fused with the gonocoxa, by having a large hypoproct, by lacking leaf- or scale-like megasetae posteriorly at the dorsal mesial margin of gonocoxa and by having two posteriad directed megasetae on the lobe mesially at the dorsal mesial margin of the gonocoxa Manota teocchii recalls two other Afrotropical species, M. clinochaeta and M. phyllochaeta . It is distinguished from both e.g. 1) by having the sternite 9 fused with the gonocoxa only on the basal fourth, not along its whole length, 2) by lacking conspicuous basal bodies of the setae on the parastylar lobe and 3) by having the ventral setae of the hypoproct divided into a more anterior and a more posterior group.
