( Figs 4 A–C )

Type material. HOLOTYPE:, INDONESIA: Sulawesi Utara, Dumoga-Bone NP, Toraut 0°34’N 123°54’E, 214m., 21–23.vii.1985, A.H. Kirk-Spriggs leg. // NMW Indonesia Expedition 1985 (Project Wallace) NMW.Z.1985.078 // Malaise trap sample, forest edge, Sungai Tumpah [on slide, NMWC] . PARATYPES: 1, same as holotype [on slide, NMWC]; 1

, same as holotype except 13–21.viii.1985 [on slide, IZBE].

Description. Male. Colour. Head light brown, face somewhat paler. Antenna yellowish to light brown. Clypeus and mouthparts pale yellowish. Thorax yellowish to light brown. Legs yellowish, hind coxa infuscated basally. Wing with brownish tinge because of microtrichia; halter yellow with blackish knob. Abdomen brown, tergites laterally and sternites lighter. All vestiture pale, yellowish or brownish, thicker setae and trichia seeming darker than finer ones. Head. Antennal flagellomere 4 ca. 1.3 times as long as wide. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, number of apically curved sensilla 4; palpomere 4 with weak parasegment; palpomere 5 ca. 1.4 times longer than palpomere 4. Number of strong postocular setae 10–11. Thorax. Anepisternum with 30–45 setae; anterior basalare with 10–11 setae, laterotergite with 23–28 setae, preepisternum 2 with 5–8 setae, metepisternum with 8–10 setae. Legs. Mid and hind tibial organs absent. Wing. R 1 meeting C within basal half of costal margin; sclerotized part of M 2 almost extending to level of tip of R 1; wing length, 1.5–1.6 mm. Hypopygium ( Figs 4A–C ). Sternite 9 laterally fused with gonocoxa, the posterior margin concave, extending over the middle between the base of gonocoxa and gonostylus, anterior margin shallowly v-shaped incised medially, setose with setae similar to these on ventral side of gonocoxa. Between the posterior part of sternite 9 and the aedeagus a spathulate sclerotized lobe. Ventral medial margin of gonocoxa simple, almost confluent with the posterior margin of sternite 9. Gonocoxa not drawn into a posterolateral lobe. Parastylar lobe bilobed, the ventral larger part subtriangular, with 2 setae at medial margin. No paraapodemal lobe identifiable. The dorsal side of gonocoxa with setae similar to those on the ventral side. Dorsal medial margin of gonocoxa simple, near the middle slightly convex, posterior third oblique, with 6–7 slightly stronger marginal setae. Medioventrally from the dorsal medial margin there is a plate-like lobe with 6–7 short, apically pointed and curved otherwise simple megasetae. One juxtagonostylar seta present, it is an acute and weakly expressed megaseta without basal body, only with the usual socket. Gonostylus small, elongated oval, about 2 times as long as wide, with a very strong long apical seta and two slightly weaker subapical setae at medial margin; ventral side setose, dorsal side non-setose. Aedeagus elongate subtriangular, without distinct lateral shoulders, the apex curved ventrad. Hypoproct extending over the apices of gonostyli, the number of ventral setae (sternite 10) ca. 30 on each half. Cerci medially separate, posteriorly widening, setose.

Female. Unknown.

Etymology. The name is Latin adjective, spathigera, bearing a small spoon-like tool, referring to the sclerite between sternite 9 and the aedeagus.

Discussion. Manota spathigera sp. nov. is similar to M. loriculata and M. loricata. For distinguishing characters, see discussion under M. loriculata .
