Manota aciculata sp. nov.

( Figs 2A–D )

Type material. HOLOTYPE: J, INDONESIA: SOUTH SULAWESI: ‘ Karaenta, forêt subprimaire sèche, 05º02.633 S, 119º44.316 E, 325 m, sur karst, Borne 25, Grand Malaise 4, 17– 26.8.2007, INDO706 M1B’ ( MNHN) . PARATYPES: 10 JJ with the same data as holotype ( MNHN, JSOC).

Description of male. Colour. Head brown, face and clypeus paler brown. Antenna brown or scapus and pedicellus paler brown. Mouthparts yellowish. Thorax paler or darker brown. Legs yellowish. Wing pale grayish brown, halter pale brown with blackish knob. Abdomen brown, sternites paler than tergites. All setosity pale, yellowish or brownish. Head. Antennal flagellomere 4, Fig. 2A . Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 4–5 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 ca. 1.4 times longer than palpomere 4. Number of strong postocular setae 9–11. Thorax. Anepisternum setose, with 25–65 setae; anterior basalare non-setose; preepisternum 2 setose, with 5–22 setae; laterotergite setose, with 9–27 setae, episternum 3 setose, with ca. 5–19 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 1.2–1.7 mm. Hypopygium ( Figs 2B–D ). Lateral margin of tergite 9 free from the gonocoxa, convex, posterior part submembranous, transverse, extending to the middle of gonocoxa, anterior margin deeply incised, the setae weaker than the ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple, the ventral setae of gonocoxa unmodified. Parastylar lobe sickle-shaped, with two setae at anterior end. Paraapodemal lobe large. Dorsal mesial margin of gonocoxa simple, posteriorly with a thumb-like setose lobe. Gonocoxa without a posterolateral lobe. The dorsal setae of gonocoxa unmodified, similar to those on the ventral side. Two juxtagonostylar megasetae, both are similar long, strong apically curved megasetae which are arising from a common basal body, about one third of the length of the megasetae. No other setae on the dorsal side of gonocoxa that deviate from the general setosity. Gonostylus large, elongate, with apicomesial lobe. Ventral side of gonostylus with long setae, dorsal side with similar setae at lateral margin, the apicomesial lobe with a couple of stronger setae deviating from other setosity at its margin and, with a row of 2–3 short subapical, submesial megasetae on the dorsal side. Aedeagus elongate subtriangular, with weak lateral shoulders. Hypoproct extending posteriorly to the middle of gonostyli, number of its ventral setae (sternite 10) ca. 10 on each half, arranged in a group. Cerci mesially separate.

Differential diagnosis. Setose anepisternum, setose preepisternum 2, setose laterotergite, apically simple, not deeply bilobed or unusually elongated, aedeagus and medially separate cerci combines Manota aciculata sp. nov. with five other Oriental species: M. abscissa sp. nov., M. angustata , M. biunculata , M. inusitata and M. ovata . It is distinguished from M. abscissa sp. nov., M. angustata and M. ovata by having megasetae on the gonostylus and from M. inusitata by having its three short megasetae, much shorter than the width of gonostylus, placed subapically on the dorsal side near the mesial margin, in M. inusitata the megasetae are long, longer than the width of gonostylus, and they are placed in a transverse apical row.

Etymology. The Name is a Latin adjective, aciculatus, -a, -um, meaning ‘bearing small spines’, referring to the small spine-like megasetae on the gonostylus.
