Manota axillata sp. nov.

( Figs 2A–D )

Type material. HOLOTYPE:, INDONESIA: Sulawesi Utara, Dumoga-Bone NP, Toraut 0°34’N 123°54’E, 232m., 3–16.ix.1985, A.H. Kirk-Spriggs leg. // NMW Indonesia Expedition 1985 (Project Wallace)

NMW.Z.1985.078 // Malaise trap sample forest, ’Rintice 3’ [on slide, NMWC]. PARATYPE: 1, same as holotype [on slide, NMWC].

Description. Male. Colour. Head brown, face paler. Antenna light brown, scape and pedicel paler. Clypeus and mouthparts pale yellowish. Thorax yellow. Legs yellowish. Wing with light brownish tinge because of microtrichia; halter yellow with brownish 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. 1.3–1.5 times as long as wide. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, number of apically curved sensilla 5, palpomere 4 with weak parasegment; palpomere 5 ca. 1.6 times longer than palpomere 4. Number of strong postocular setae 9–10. Thorax. Anepisternum with 56–63 setae; anterior basalare and laterotergite non-setose, preepisternum 2 with 19 setae, metepisternum with 12–13 setae. Legs. Mid and hind tibial organs absent. Wing. R 1 meeting C within basal half of costal margin; sclerotized part of M

not extending to level of tip of R

; wing length, 1.8–2.0 mm. Hypopygium ( Figs 2 A–D ). Sternite 9 laterally free from gonocoxa, the posterior margin concave, extending well over the middle between the base of gonocoxa and gonostylus, anterior margin deeply u-shaped incised medially, setose with setae similar to those on ventral side of gonocoxa. Ventral medial margin of gonocoxa simple. Gonocoxa not drawn into a posterolateral lobe. Parastylar lobe large, with medial lobe bearing 3–4 setae. Paraapodemal lobe not exposed in ventral view, well visible in dorsal view ( Fig. 2A ). The dorsal side of gonocoxa with setae similar to those on the ventral side. Dorsal medial margin of gonocoxa with aggregation of medially directed fine setae. Dorsal posterior margin of gonocoxa drawn into a turbinate sub-rectangular lobe with 10–12 setae on its dorsal surface and at medial margin. Two juxtagonostylar setae present, the ventral one is a flattened, curved and simple megaseta, the dorsal one is a considerably smaller acute seta, both arising from a common finger-like basal body that is about half of the length of the ventral megaseta. Gonostylus elongate oval, about 3 times as long as wide, dorsal and ventral sides setose, dorsal side with a small subapical ridge bearing 5–6 stronger medially directed setae, basomedial angle pronounced as a small lobe with 4–5 medially directed setae, microtrichia mediodorsally prominent. Aedeagus shortly subtriangular, with weakly expressed lateral shoulders, the apex curved ventrad. Hypoproct not extending over the posterior margin of gonocoxa, the number of ventral setae (sternite 10) ca. 5 in one row on each half. Cerci medially separate, setose.

Female. Unknown.

Etymology. The name is Latin adjective, axillata, with a little heel, referring to the heel-like lobe basomedially on the gonostylus.

Discussion. Following the key by HIPPA (2011), this species runs to couplet 90 including M. acutangula Hippa, 2006 and M. pectinata Hippa, 2006 . Manota axillata sp. nov. is distinguished from both by having a basomedial heel-like lobe on the gonostylus and by lacking a long posterolateral lobe on the gonocoxa. The heel-like lobe situated basomedially on an elongated gonostylus in M. axillata is somewhat reminiscent of M. angustata Hippa, 2006 , but the latter also has the gonostylus with a subapical process.
