Manota auriculata sp. n.

( Figs 5 A, B, C)

Male. Colour. Head brown, frons, vertex and occiput not distinctly darker brown, antennal scape, pedicel and basal flagellomeres slightly paler brown, mouthparts pale yellowish. Thorax unicolorous brown. Legs pale yellowish-brown, darker than mouth parts, femur 3 infuscated at apical fourth, very slightly so also at base.

Wing unicolorous yellowish-brown; haltere yellowish-brown with dark brown knob. Abdomen pale brown. All the setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 5 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 4 apically expanded curved sensilla; palpomere 4 with parasegment. Number of postocular setae 13. Thorax. Anepisternum setose, with 39 setae, anterior basalare setose, with 8 setae, preepisternum 2 setose, with 10 setae, laterotergite non-setose, episternum 3 setose, with 4 setae. Wing. Length 1.9 mm. Hypopygium, Figs 5 B and C: Sternite 9 about two-thirds of the ventral length of gonocoxa, lateral margin sharply delimited, unusually oblique, posterior margin transverse, with a narrow, deep medial cleft, anterior margin incised, the setae similar to the ventral setae of gonocoxa. Ventral mesial margin of gonocoxa strongly concave. Parastylar lobe large, with several setae at mesial margin. Paraapodemal lobe distinct, large, well exposed in ventral view except for being partly covered by the parastylar lobe. Dorsal mesial margin of gonocoxa simple, with a group of prominent setae subapically. Two juxtagonostylar setae present, one of which is an unmodified megaseta, the other a very strong, partly flattened and spiralled megaseta, the setae without a distinct common basal body. Gonostylus simple, elongate-oval, with moderately long unmodified setae, on the apical half of the dorsal side with an area of densely placed rather short curved setae. Tegmen unusual in shape, almost equally broad from base to apex and with characteristic apico-lateral auricles. Hypoproct posteriorly reaching over the middle of gonostylus, with some 12 setae on each half. Cerci medially separate.

Female unknown.

Discussion. M. auriculata is not similar to any other described Manota . The apically broad tegmen with the unusual lateral auricles identify the species. The tegmen is reminiscent of one other species, M. bifida Hippa and Papp , in which it is also apically broad and has apicolateral lobes, but in M. bifida the lobes are very long, nearly as long as all the more basal part of the tegmen and they are directed posteriad. Other closer similarities between the two species are difficult to see. So far as the Oriental fauna is concerned, the deeply rectangularly concave ventral mesial margin of gonocoxa is unique. The more dorsal one of the juxtagonostylar megasetae is strongly incrassate, flattened and S-shaped and is reminiscent of M. collina sp. n., but is twice as broad.
