Male. Colour. Head brown, face yellow. Scape, pedicel and first three segments of flagellum yellowish, rest of flagellar segments light brown. Clypeus, mouthparts pale yellowish. Thorax yellow to light brown, with laterotergite and mediotergite somewhat darker, and preepisternum 2, proepisternum and antepronotum pale yellow. Legs yellowish, basal fourth of mid and hind femora brownish, tarsi appear brown due to dense trichia. Wing with light brownish tinge due to microtrichia; halter yellowish with dark brown knob. Abdomen brown, sternites and lateral tergites lighter. All vestiture pale, yellowish or brownish, thicker setae and trichia appear darker than finer ones.

Head. Antennal flagellomere 4 ca. 1.9 times as long as wide. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 3 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 ca. 1.4 times longer than palpomere 4. 10–11 strong postocular setae. Thorax. Anepisternum with 29–41 setae; anterior basalare non-setose, laterotergite with 27–29 setae, preepisternum 2 with 7–11 setae; metepisternum with 2–3 setae. Legs. Mid and hind tibial organs absent. Wing. R 1 meeting C within basal half of costal margin; sclerotized part of M 2 extending to level of tip of R 1; wing length 2.0– 2.1 mm. Hypopygium ( Figs 1 B , 6 A–F). Sternite 9 laterally free from gonocoxa, not extending to middle between bases of gonocoxa and gonostylus, posterior margin with wide V-shaped concavity, anterior margin with very deep U-shaped wide incision dividing sternite almost in half, lateroposterior margin of both halves with 3–5 setae, similar to those on ventral side of gonocoxa. Ventral medial margin of gonocoxa straight, with marginal row of medially directed setae, the posterior-most seta slightly stronger. Parastylar lobe small, conical, covered by ventral medial margin of gonocoxa, with an apical strong and 3–4 more basal weaker setae. No paraapodemal lobe identifiable. Dorsal medial margin of gonocoxa simple, slightly bulging medially, posteriorly at the medial margin, on more ventral level, with (1) a more anterior plate-like submembranous rounded lobe bearing 7–10 short and simple, marginal and submarginal setae, and (2) a more posterior, subtriangular, dorsally setose lobe with a dense aggregation of apical setae. Two juxtagonostylar seta present: ventral one a simple unmodified megaseta, shorter than the dorsal; dorsal one flattened and obvolute megaseta bearing a whiplike apical branch, both megasetae arising from basally fused short basal bodies. Gonostylus club-shaped, more than half length of gonocoxa, ventrally widely setose, dorsally with 4–5 setae subapically, apical margin with 3 longer setae, posteromedial margin somewhat drawn out medially, bearing a dense aggregation of about 10 long medially directed and curved setae deviating from other setae of the gonostylus. Aedeagus elongated subtriangle, without lateral shoulders, apex curved ventrad. Hypoproct large, number of ventral setae (sternite 10) ca. 20 on each half, anteroventrally with two long setae deviating from other setosity of hypoproct. Cerci medially fused, setae arranged along posterior margin.

Female. Unknown.

Etymology. The species is named in honour of Dr. Vladimir (Vlad) Blagoderov (NMS, Edinburgh, UK), the collector of the type material and an active researcher of recent and fossil fungus gnats.

Comments. In the key to Neotropical Manota by Kurina et al. (2018), M. vladi sp. n. runs to couplet 9 (setose laterotergite, non-setose anterior basalare and gonocoxa without a posterolateral lobe) and groups together with five species, viz. M. clava Kurina, Hippa & Amorim, 2017 ( Colombia), M. mexicapan Hippa & Huerta, 2009 ( Mexico) , M. nubicola Hippa & Huerta, 2009 ( Mexico) , M. planistylus Jaschhof & Hippa, 2005 ( Costa Rica) and M. rectolobata Jaschhof & Hippa, 2005 ( Costa Rica). Manota vladi differs from them as well as all other Neotropical species in the large, club-shaped gonostylus with aggregation of long and twisted setae at the posteromedial corner. In having medially fused cerci, the new species resembles three other Neotropical species, viz. M. appendiculata Hippa & Kurina, 2013 , M. inermis Hippa & Kurina, 2013 and M. quantilla Hippa & Kurina, 2013 . Otherwise the species is significantly different.

Types. Holotype. Male , DOMINICAN REPUBLIC: Amando Bermudez NP, 19.0638N 70.8759W (+/- 5m), 1180 masl., Malaise trap, 14–20.iv.2019, leg V. Blagoderov (slide mounted, NMS) . Paratypes. 2 males, same as holotype (slide mounted, NMS and IZBE) .
