Description. Male. Colour. Head light brown, face somewhat paler. Antenna light brown, scape and pedicel
somewhat paler. 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. 1.3–1.4 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. 1.5 times longer than palpomere 4. Number of strong postocular setae 10–12. Thorax. Anepisternum with 41–45 setae; anterior basalare with 9–10 setae, laterotergite with 20–25 setae, preepisternum 2 with 5–8 setae, metepisternum with 10–15 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 3A–D). Sternite 9 laterally fused with gonocoxa, the posterior margin concave with small medial convexity, posteriorly extending over the middle between the base of gonocoxa and gonostylus, anterior margin shallowly v-shaped incised medially, setose with setae similar to those on ventral side of gonocoxa. On the dorsal side at posterior margin of sternite 9 a subtriangular sclerotized lobe. Ventral medial margin of gonocoxa simple, almost confluent with the posterior margin of sternite 9. Gonocoxa drawn into a short and narrow posterolateral setose lobe with 2–3 subapical setae on medial side that deviating from other ventral setosity of gonocoxa. Parastylar lobe subtriangular, weakly bilobed (even if poorly visible in Fig. 3B), with 2 setae at medial corner. No paraapodemal lobe identifiable. The dorsal side of gonocoxa with setae similar to those on the ventral side, 6–7 setae at dorsal posterior margin of gonocoxa stronger, apically curved. Posterior third of dorsal medial margin of gonocoxa bulging medially. Medioventrally from the dorsal medial margin there is a plate-like lobe with 4–5 long and apically slightly hooked megasetae. One juxtagonostylar setae present, it is a curved acute megaseta arising from finger-like basal body that is about half of the length of the seta. Gonostylus small oval, ventral side setose, with a very strong long apical seta, slightly weaker subapical medial seta and 5–6 short but somewhat stronger setae along lateral margin, 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, loriculata, with a little leather cuirass, referring to the sclerite between sternite 9 and the aedeagus.
Discussion. Following the key by HIPPA (2011), this species runs to couplet 10 because of the setose anepisternum. However, having 5–8 setae on preepisternum 2, it does not match either of the two options included. By thoracic vestiture and the male hypopygium Manota loriculata sp. nov. is similar to M. loricata Hippa & Ševčík, 2013 described from South Sulawesi and to M. spathigera described below. All the three of these species differ from other similar Manota by having an unusual plate-like lobe between sternite 9 and the aedeagus. Manota loriculata differs from the other two species by having: 1) 4–5 long, blunt and apically slightly hooked megasetae on a plate like lobe ventrally from the dorsal medial margin of the gonocoxa (4–5 short and blunt megasetae in M. loricata, an aggregation of 6–7 short and apically curved acute megasetae in M. spathigera), 2) posterior third of the dorsal medial margin of the gonocoxa bulging and lobe-like medially (straight in M. loricata, slightly convex in M. spathigera), 3) gonocoxa drawn into a short and narrow posterolateral setose lobe (not drawn into a lobe in other species), 4) posterior margin of sternite 9 concave with a small medial convexity (convex in M. loricata, concave without a small medial convexity in M. spathigera), and 5) sclerotized lobe dorsally from the sternite 9 and ventrally from the aedeagus subtriangular (semicircular in M. loricata, spathulate in M. spathigera). Furthermore, all three species have a bilobed parastylar lobe that may be difficult to observe in some mounts; the number of parastylar setae is two in M. loriculata and M. spathigera, 3–4 in M. loricata.
