Description. Male. Colour. Head light brown, face paler. Antenna light brown, scape and pedicel somewhat paler. Clypeus and mouthparts pale yellowish. Thorax yellowish. Legs yellowish, hind coxa slightly infuscated basally. Wing with light 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 4–5; palpomere 4 with weak parasegment; palpomere 5 ca. 1.5 times longer than palpomere 4. Number of strong postocular setae 10–11. Thorax. Anepisternum with 39–47 setae; anterior basalare non-setose, laterotergite with 11–15 setae, preepisternum 2 with 12–15 setae, metepisternum with 11–17 setae. Legs. Mid and hind tibial organs absent. Wing. R 1 meeting C within basal half of costal margin; sclerotized part of M 2 not extending to level of tip of R 1; wing length, 1.6–1.7 mm. Hypopygium ( Figs 1A–D ). Sternite 9 laterally free from gonocoxa, rounded, the posterior margin straight, extending to the middle between the base of gonocoxa and gonostylus, anterior margin deeply v-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 crescent-shaped with one medially directed seta on anterior part. Paraapodemal lobe discernible, apically tapering. The dorsal side of gonocoxa with setae similar to those on the ventral side. Dorsal medial margin of gonocoxa simple, posteriorly with setose flat lobe at more ventral level covered partly by medial and posterior margins. Two juxtagonostylar setae present, both are simple sigmoid megasetae, arising from a common finger-like basal body that is about half of the length of megasetae. Gonostylus elongated, about 4 times as long as wide basally, apically slightly widening with 4–5 medially directed somewhat stronger setae apicomedially. Aedeagus shortly subtriangular, with lateral shoulders, the apex curved ventrad. Hypoproct not extending over the posterior margin of gonocoxa, the number of ventral setae (sternite 10) ca. 15 on each half. Cerci medially separate, setose.

Female. Unknown.

Etymology. The species is named after Dr. Ashley Kirk- -Spriggs, who collected the type material of all the new species described in this paper.

Discussion. According to the key to Oriental species by HIPPA (2011), Manota ashleyi sp. nov. runs to couplet 29 and groups together with M. ovata Hippa, 2006 , M. angustata Hippa, 2006 and M. biunculata Hippa & Papp, 2007 . It also resembles M. abscissa Hippa & Ševčík, 2013, described from South Sulawesi. All five species have setose anepisternum, preepisternum 2 and laterotergite, simple subtriangular aedeagus, medially separate cerci, and oval or elongated gonostylus without any megasetae. Manota ashleyi has the gonostylus apically slightly widening with 4–5 medially directed somewhat stronger setae apicomedially, while the gonostylus is: (1) ovate, with a conspicuous fringe of long setae along the whole medial margin in M. ovata , (2) elongated, with very long setae along the apical half of the medial margin in M. abscissa, (3) with subapical process on the medial side in M. angustata , and (4) medially concave in M. biunculata . The aedeagus of M. ashleyi is rather short with weak lateral shoulders like in M. ovata , M. angustata and M. abscissa, while it is considerably larger in M. biunculata . The crescent-shaped parastylar lobe has one antero-mesial seta in M. angustata and M. ashleyi while it has a couple of setae in M. ovata and M. abscissa. Manota biunculata has the parastylar lobe differently outlined with one seta arising from a small lobe on its anterior part (cf. HIPPA 2007: fig. 1B).
