Manota pellii sp. n.

( Figs 17 A, B, C, D)

Male. Colour. Head pale brown, frons, vertex, occiput and antennal flagellum darker brown, mouthparts pale yellowish. Thorax pale brown, posterior part of scutum, scutellum and part of mediotergite darker brown, pro- and mesothoracic pleura paler brown. Legs pale yellowish, femur 3 slightly infuscated on apical third. Wing unicolorous pale brown; haltere pale brown with dark brown knob. Abdomen brown. All the setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 17 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 5 apically expanded curved sensilla; palpomere 4 with parasegment. Number of postocular setae 11. Thorax. Anepisternum setose, with 71 setae, anterior basalare non-setose, preepisternum 2 setose, with 24 setae, laterotergite non-setose, episternum 3 setose, with 38 setae. Wing. Length 2.0 mm. Hypopygium, Figs 17 B, C and D: Sternite 9 about one-half of the ventral length of gonocoxa, lateral margin sharply delimited, posterior margin transverse with a medial notch, anterior margin deeply incised, the setae similar to the ventral setae of gonocoxa. Ventral mesial margin of gonocoxa strongly sigmoid. Parastylar lobe rather small, with 3 mesial setae arising from narrow projections. Paraapodemal lobe distinct and well exposed in ventral view. Dorsal mesial margin of gonocoxa simple, with a lobe-like setose apico-mesial angle. Ventrally from the latter with a setose lobe. Two juxtagonostylar setae present: these are two rather unmodified curved megasetae arising from the tip of a long common basal body, which is about twice as long as the megasetae. At the juxtagonostylar setae, on their dorsal side, is a seta which also arises from a similar narrow basal body. Gonostylus simple, shortoval, narrowing towards base, its ventral setae moderately long, the setae apicodorsally strong but short, otherwise dorsal setae almost absent. Tegmen subtriangular, with lateral shoulders. Hypoproct extending posteriorly to middle of gonostylus, with some 10 setae on each half, forming a mesial row. Cerci medially separate.

Female unknown.

Etymology. The species epithet is dedicated to Mr Jarmo Pelli, Stockholm, whose assistance in the study of the World Manota has been indispensable.

Discussion. M. pellii resembles M. perpusilla Hippa in having two juxtagonostylar megasetae arising from a long and narrow common basal body and in having on the dorsal side of these a similar basal body with one seta. M. pellii differs from M. perpusilla in having the gonostylus much broader, short-oval instead of elongate-oval (twice as broad as long), and by lacking a very long flattened seta subbasally at its mesial margin. The diverging juxtagonostylar setae are probably also a diagnostic character of the species.
