Manota siciliculata sp. n.

Figs 12 A–E

Male. Colour. Head brown, face somewhat paler. Antenna including scape and pedicel light brown. Clypeus and mouthparts pale yellowish. Thorax yellow, medial part of scutum and scutellum somewhat darker. Legs yellowish, hind coxa basally and hind femur apically slightly infuscated. Wing hyaline; haltere yellow with brownish knob. Abdomen light brown, medial 2/3 of tergites darker. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer ones. Head. Antennal flagellomere 4 Fig. 12 A. Palpal segment 3 of maxillary palpus with apicomedial thumb-like extension, with five apically strongly flattened and curved sensilla; palpal segment 4 with parasegment; palpal segment 5 ~1.7 times longer than palpal segment 4. Nine strong postocular setae. Thorax. Anepisternum with 53–65 setae; anterior basalare non-setose; preepisternum with 22–25 setae; laterotergite with 26 setae; metepisternum with 7–11 setae. Legs. Mid- and hind tibial organs absent. Wing. R1 meeting C within the basal half of the costal margin; the sclerotized part of M2 proximally not extending to the level of the tip of R1; wing length 2.1 mm. Hypopygium, Figs. 12 B–E. Sternite 9 elongate subquadrangular, about half the ventral length of gonocoxa, laterally free from gonocoxa, anteriorly deeply incised, the incision separates the sclerite almost into two halves, the setae anteriorly similar to the ventral setae of gonocoxa, posteriorly conspicuously stronger. Ventromedial margin of gonocoxa simple, curved. The ventral setae of gonocoxa unmodified. Parastylar lobe transverse, sickle-shaped, at base (lateroventrally) with a small sub-lobe, at anteromedial margin with a strong seta, on dorsal surface with ~3 weaker setae. Paraapodemal lobe similar to Fig. 2 B. Dorsomedial margin of gonocoxa curved, with a row of short setae beyond the middle; posterior part of the medial margin together with the posterior margin of gonocoxa drawn into a large oblique lobe bearing four apical setae and a couple of setae on its ventral side. The dorsal setosity of gonocoxa unmodified, similar to the ventral one except for a couple of longer setae posteriorly. Gonostylus nearly as long as the ventral length of gonocoxa, with convex lateral and concave medial surface, at apicomedial margin with two short claw-like megasetae, other setosity unmodified, confined on lateral/ventral part; no conspicuous microtrichia observed on the medial surface. Two juxtagonostylar setae present, both are megasetae, with shorter rather unmodified and longer curved, both arising from a common basal body that is slightly longer than the longer megaseta. Aedeagus elongate subtriangular, without shoulders, the apex curved ventrad. Hypoproct posteriorly extending to the middle of gonostylus, its ventral part (sternite 10) with ~20 scattered setae on each half. Cerci medially separate, with apical setae only.

Female unknown.

Discussion. Manota siciliculata belongs to a large group of species as defined under M. acris . Within this group M. siciliculata resembles M. hamulata , M. bicuspis and M. nimia in having two short megasetae (instead of one long, or two long together with two shorter ones) subapically on the gonostylus. Manota siciliculata is distinguished from all three by 1) the sickle-shaped parastylar lobe, 2) the posterior setae on sternite 9 conspicuously broader and 3) the juxtagonostylar setae both being megasetae.

Etymology. The name is Latin, siciliculata [having small sickles] referring to the sickle-shaped parastylar lobes.
