Manota loricata sp. nov.

( Figs 4A–D )

Type material. HOLOTYPE: J, INDONESIA: SOUTH SULAWESI: ‘ Bulusaraung, forêt secondaire altitude, 04º55.861′S, 119º45.369′E, 1066 m, Site 1-1, Grand Malaise 1, 18– 27.8.2007, INDO708 M1B’ ( MNHN).

Description of male. Colour. Head dark brown, face and clypeus brown. Antenna brown, scapus, pedicellus and three basal flagellomeres paler brown. Mouthparts yellowish. Thorax brown, preepisternum 2 ventrally paler. Legs yellowish, coxa 3 infuscated at base. Wing brownish, halter pale brown with blackish knob.Abdomen brown, sternites paler than tergites. All setosity pale, yellowish or brownish. Head. Antennal flagellomere 4, Fig. 4A . Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 4 apically curved sensilla; palpomere 4 with poorly expressed parasegment; palpomere 5 ca. 1.3 times longer than palpomere 4. Number of strong postocular setae 10. Thorax. Anepisternum setose, with 43 setae; anterior basalare setose, with 15 setae; preepisternum 2 setose, with 11 setae; laterotergite setose, with 30 setae; episternum 3 setose, with 11 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 M 2 extending near to the level of the tip of R1; wing length 1.7 mm. Hypopygium ( Figs 4B–D ): Tergite 9 laterally fused with gonocoxa, posterior margin extending well over the middle length of gonocoxa, anterior margin deeply incised, the setae similar to ventral setae of the gonocoxa. On the dorsal side of the posterior part of sternite 9 there is a semicircular sclerotized lobe. Ventral mesial margin of gonocoxa simple, the ventral setae of gonocoxa unmodified. Parastylar lobe large, bilobed, with 3–4 very strong setae. Paraapodemal lobe not identifiable. Dorsal mesial margin of gonocoxa simple, posteriorly with a few conspicuous angled setae. Gonocoxa without a posterolateral lobe. Otherwise the dorsal setae of gonocoxa unmodified, similar to those on the ventral side. One juxtagonostylar seta present, it is a curved acute megaseta arising from basal body which is ca. one third of the length of the seta. Anteriorly from the juxtagonostylar megaseta there is a plate-like lobe bearing 4–5 short blunted megasetae. Gonostylus small oval, with indistinct mesial lobe, the ventral side setose, dorsal side non-setose, the mesial lobe with a very strong long seta, the apical margin with strong curved setae. Aedeagus elongate subtriangular, without distinct lateral shoulders, the apex curved ventrad. Hypoproct large, extending posteriorly over the apices of gonostyli, number of its ventral setae (sternite 10) ca. 30, these setae widely distributed over the ventral surface. Cerci mesially separate.

Differential diagnosis. Manota loricata sp. nov. belongs to a large group of species which have setose anepisternum, setose laterotergite, setose anterior basalare and which have the sternite 9 laterally fused with the gonocoxa. It differs from all by having a sclerotized semicircular lobe dorsally from the posterior part of tergite 9. This lobe is evidently homologous with a more or less large membranous part in the same position seen in a number of the reminiscent species. In the key to Oriental and Palaearctic Manota (cf. HIPPA 2011), M. loricata sp. nov. runs to M. simplex Hippa, 2006 known from Borneo, Peninsular Malaysia and Thailand. The modified setae posteriorly on the dorsal mesial margin of the gonocoxa are in M. loricata sp. nov. less modified, longer and more like usual setae when compared with the almost megaseta-like flame-shaped setae in M. simplex . Further, M. loricata sp. nov. differs from M. simplex by having a well-developed juxtagonostylar megaseta, by having fewer megasetae on the lobe at the dorsal mesial margin of the gonocoxa (4–5 contra ca. 10) and by having a short oval gonostylus with unusually strong setae instead of an elongated gonostylus with only fine setae. The short oval shape of the gonostylus with the coarse setosity and the extremely coarse setosity of the parastylar lobe alone distinguish M. loricata sp. nov. from any other known Manota .

Etymology. The name is a Latin adjective, loricatus, -a, -um, meaning ‘with cuirass’, referring to the cuirass-like lobe at the male tergite 9.
