Hippa, Heikki & Papp, László, 2007, The genus Manota Williston (Diptera: Mycetophilidae) in Thailand, with the description of seven new species, Zootaxa 1528, pp. 41-60 : 49-51

Manota dentata sp. n.

( Figs 5 A, B)

Body brown, length ca. 2.0 mm (holotype), 2.0– 2.2 mm (paratypes), wing length 1.65 mm (holotype), 1.70– 1.80 mm (paratypes).

Male. Head. Flagellomere 4 1.5 times as long as broad with 0.03 mm long trichia. Postocular setae (7–8) rather long, thick and black. Thorax. Anepisternum setose. Anterior basalare setose. Setae of preepisternum 2 not observed. Laterotergite setose. Setae of episternum 3 not observed. Mid and hind trochanters, bases of mid and hind femora as well as apical 1/3 of hind femur darkened. Wing. Wing membrane light brownish, dorsally without setae at posterior margin, veins light brown. Sc distally of h setose. Ratio of visible sections of veins M1 and M2 32/80 (holotype) 41/84, 40/82 (paratypes). A1 indicated by a few setae. Hypopygium ( Figs 5 A, B). Tergite 9 extending posteriorly as far as the ventral part of gonocoxa, laterally fused with gonocoxa except at extreme apex, anterior margin with a rather shallow incision, the setae similar to those on gonocoxa. Parastylar lobe very large, almost the size of gonostylus, with 3–4 posteriorly directed setae. Paraapodemal lobe indistinct, not visible in ventral view. Dorsal mesial margin of gonocoxa sigmoid, partly covering a large lobe with ca. 10 blunt-ended megasetae on margin. One juxtagonostylar seta present: it is a normal seta arising from a basal body, which is broad and shorter than the seta. Gonostylus rather small, with long setae, apically with a few stronger setae arising from a weak lobe. Tegmen elongate-triangular, with sloping lateral shoulders. Hypoproct large, parallel-sided, extending posteriorly almost as far as gonostylus, with ca. 30 scattered setae. Cerci medially separate.

Female unknown.

Discussion. In the Oriental fauna, M. dentata is similar to M. heptacantha Hippa , but differs e.g. by having the megasetae mesially on the dorsal side of gonocoxa shorter, flattened from base to tip and not only at tip, and about twice as broad as in M. heptacantha . In addition, the lobe bearing the megasetae is more pronounced than in M. heptacantha . M. dentata is also similar to some Afrotropical species, especially M. serrata Söli and M. sespinea Söli. These two species differ from M. dentata by having the megasetae not flattened but narrow and pointed, and they have a flattened juxtagonostylar megaseta on the gonocoxa, unlike M. dentata which has only an unmodified normal seta in the homologous position.

Types. Holotype. Male, Thailand: Khao Pu-Khao Ya N. P., along a forest brook below the (Pak Yam) waterfall, No. 42, Nov 21, 2004, leg. L. Papp & M. Földvári (gen. prep. Bud 30). Paratypes. 3 males, Trang Prov., Palian District, Nam Tok Nam Pan Forest Park, over streams & vegetation around waterfalls, No. 35, Nov 17, 2004, leg. L. Papp & M. Földvári (gen. prep. Bud 16, 26, 27).
