( Figs 5A–D )

Type material. HOLOTYPE: J, INDONESIA: SOUTH SULAWESI: ‘ Karaenta, forêt subprimaire sèche, 05º01.662′S, 119º44.392′E, 254 m, au sol, Borne 27, Grand Malaise 2, 17– 26.8.2007, INDO704 M1B’ ( MNHN).

Description of male. Colour. Head brown, face and clypeus paler brown.Antenna pale brown. Mouthparts yellowish. Thorax pale brown. Legs yellowish, coxa 3 infuscated at base. Wing pale greyish brown, halter pale brown with blackish knob.Abdomen brown, sternites very pale. All setosity pale, yellowish or brownish. Head. Antennal flagellomere 4, Fig. 5A . Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 5 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 ca. 1.4 times longer than palpomere 4. Number of strong postocular setae 9. Thorax. Anepisternum setose, with 49 setae; anterior basalare non-setose; preepisternum 2 setose, with 30 setae; laterotergite non-setose; episternum 3 setose, with 12 setae. Legs. Mid and hind tibial organs absent. Wing. R1 meeting C well on the basal half of the costal margin; the sclerotized part of M2 extending near to the level of the tip of R1; wing length 1.4 mm. Hypopygium ( Figs 5B–D ). Lateral margin of tergite 9 free from the gonocoxa, curved, posterior part submembranous, convex, extending to the middle of gonocoxa, anterior margin deeply incised, the setae varying in size, some being weaker than the setae on the gonocoxa, some equal in size and a few even stronger. Ventral mesial margin of gonocoxa simple, the ventral setae of gonocoxa unmodified. Parastylar lobe elongate subquadrangular, basally rather distinctly bilobed, with 3 setae at anterior end. Paraapodemal lobe small, in Fig. 5B seen posteriorly from the parastylar lobe. Dorsal mesial margin of gonocoxa simple, posteriorly with a ridge-like setose lobe. Gonocoxa with a large posterolateral lobe with a couple of setae basolaterally and a few setae on apical part. Otherwise the dorsal setae of gonocoxa unmodified, similar to those on the ventral side. Two juxtagonostylar setae present, the dorsal one a stout apically curved megaseta arising from a basal body which is over half the length of megaseta, the ventral one of the juxtagonostylar setae an unmodified seta arising from the side of the basal body of the latter. No other setae on the dorsal side of gonocoxa that deviate from the general setosity. Gonostylus large, broad, almost semicircular, the ventral side setose, the dorsal side largely non-setose, at apical and apicomesial margin there are ca. 7 short setae curving dorsad. Aedeagus elongate subtriangular, without distinct lateral shoulders, the apex curved ventrad, the curved part long. Hypoproct extending posteriorly to the middle length of gonostyli, number of its ventral setae (sternite 10) 6–7 on each half, these setae very strong and arranged in a row. Cerci mesially separate.

Differential diagnosis. Manota paulula sp. nov. is similar to M. licina sp. nov.. The species can, however, easily be distinguished by the following characters: 1) in M. paulula sp. nov. the setosity on sternite 9 includes several weaker and stronger setae, in M. licina sp. nov. the setae are weak except for one very strong and long seta on both sides, 2) in M. paulula sp. nov. the basomesial part of gonostylus is rounded, in M. licina sp. nov. there is a heel-like lobe, 3) in M. paulula sp. nov. there are seven strong setae at the apical margin of the gonostylus, in M. licina sp. nov. these setae are thick megasetae, and 4) in M. paulula sp. nov. the posteromesial lobe on the dorsal side of the gonocoxa is weak and with usual setae, in M. licina sp. nov. the lobe is strong and apically armed with numerous blunted megasetae.

Etymology. The name is a Latin adjective, paululus, -a, -um, meaning ‘very small’, referring to the small size of the fly.
