description: Manota aconcinna sp. n.
(Figs 2 A, B, C)
Male. Colour. Head pale brown, frons, vertex and occiput darker brown, antennal flagellomere 1 and ventral part of flagellomeres 2 and 3 paler than rest of antenna, mouthparts pale yellowish. Thorax pale brown, anterior and ventral parts of pleura paler than the other parts. Legs pale yellowish, femur 3 darker infuscated on apical fourth. Wing unicolorous yellowish-brown; haltere yellowish-brown with dark brown knob. Abdomen pale brown. All the other setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head (lost in holotype). Antennal flagellomere 4, Fig. 2 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 4 apically expanded curved sensilla; palpomere 4 with parasegment. Number of postocular setae 11. Thorax. Anepisternum setose, with 29–33 setae, anterior basalare setose, with 5–6 setae, preepisternum 2 setose, with 12–33 setae, laterotergite non-setose, episternum 3 setose, with 8–14 setae. Wing. Length 1.7 mm. Hypopygium, Figs 2 B, C and D: Sternite 9 about one-half of the ventral length of gonocoxa, lateral margin sharply delimited and forming a contiguous arch with posterior margin, anterior margin deeply incised, the sides separated by a medial furrow, the setae similar to the ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple. Parastylar lobe large, with several rather fine setae at mesial margin. Paraapodemal lobe well exposed in ventral view. Dorsal mesial margin of gonocoxa simple, with an oblique setose subapical lobe, with three or four small but prominent setae between the lobe and the gonostylar apodeme; the postero-mesial part of gonocoxa probably slightly inflated in the mount and would probably take up a similar position to that in Fig. 21 B. Two juxtagonostylar setae present, both of these equally large simple megasetae and arising from a short basal body which is about one-fourth of their length. Gonostylus simple, elongate-oval with rather long unmodified setae, subapically on dorsal side with a transverse row of long setae differing from the other scanty setosity. Tegmen subtriangular with the apex narrow and asymmetric, the lateral shoulders weak. Hypoproct large, extending posteriorly to the middle of gonostylus, with some 15 setae on each half, 5 of these setae forming a conspicuous oblique ventral row, 4 or 5 others forming an unusual lateral group. Cerci medially separate.
Female unknown.
Discussion. M. aconcinna is similar to M. mirifica Hippa and Papp and M. submirifica sp. n. all of which differ from the other known Manota by the asymmetric apex of tegmen. It differs from both by having the base of parastylar lobe narrow, about half the distance between the posterior margin of sternite 9 and the base of gonostylus, whereas it is very broad in the two other species, two-thirds or more of the distance between sternite 9 and the gonostylus. The apex of the tegmen is similar to M. mirifica in being straight, not downturned as in M. submirifica. There is a subapical lobe on the dorsal mesial margin of gonocoxa as in M. submirifica but not in M. mirifica, and the setae on the hypoproct are in groups as in M. submirifica, not evenly distributed as they are in M. mirifica. M. aconcinna, M. mirifica and M. submirifica are similar to M. collina sp. n. and M. planilobata sp. n. The two latter differ, in addition to the symmetric apex of the tegmen, by having one of the two juxtagonostylar megasetae conspicuously stronger than the other one.
