Notes on Oriental and Australasian Manotinae (Diptera, Mycetophilidae), with the description of thirteen new species Author Hippa, Heikki Author Ševċík, Jan text Zootaxa 2010 2333 1 25 journal article 10.5281/zenodo.205203 9be87532-d3ac-492e-9ee3-250b772bbdbe 1175-5326 205203 Manota radula sp. n. Figs 10 A–D Male. Colour . Head pale brown, frons, vertex and dorsal part of occiput darker brown. Antenna unicolorous pale brown. Mouthparts pale yellowish. Thorax pale brown, postero-medial part of scutum and scutellum darker. Leg 1 and coxae 2 and 3 pale yellowish, the more distal parts of legs 2 and 3 lost in both specimens. Wing unicolorous pale yellowish-brown; haltere yellowish-brown with darker brown knob. Abdominal tergites brown, sternites pale brown. All setosity yellowish or brownish, thicker setae apparently darker than finer setae and trichia. Head . Antennal flagellomere 4, Fig. 10 A. Palpomere 3 of maxillary palpus without apicomesial extension, without apically expanded curved sensilla; palpomeres 4 and 5 broken off on both sides in both specimens. Ten to twelve strong postocular setae. Thorax . Anepisternum non-setose; anterior basalare non-setose; preepisternum 2 non-setose; laterotergite non-setose; episternum 3 setose, with 16–18 setae. Wing. Similar to Fig. 1 A; wing length 1.6–1.8 mm . Hypopygium, Figs 10 B, C, D. Sternite 9 small, about one fourth of ventral length of gonocoxa, with sharply delimited convergent lateral margins, posterior margin indented, anterior margin deeply incised, setae similar to adjacent setae of gonocoxa. Mesial margin of gonocoxa slightly concave, in the mount of the holotype the posterior part is turned laterad ( Fig. 10 C), in the paratype it is lobed ventrad. Parastylar lobe in anterior-posterior direction very long, almost as long as ventral mesial margin of gonocoxa, with several setae anteriorly at mesial margin and 2 setae in more lateral position. Paraapodemal lobe exposed in ventral view. Dorsal mesial margin of gonocoxa simple, slightly sigmoid, slightly ventrally a folded submembranous lobe subapically at dorsal mesial margin, ventrally of this a narrow lobe with two truncate megasetae, even more ventrally a similar lobe with ca. 3 truncate setae. The two latter could also be part of one lobe only. No apical apophysis dorsally on gonocoxa. Two long juxtagonostylar setae, both subequal, rather unmodified megasetae arising from a common short basal body. Gonostylus complex, with a narrow lateral part, a broad mesial part and the intermediate part lobe-like both dorsally and ventrally; lateral part with moderately long setae on ventral side, with fine setae on apical half of dorsal side, intermediate part setose only on ventral side, mesial part non-setose ventrally, dorsally at mesial margin with many rows of short curved setae. Aedeagus elongate subtriangular, without prominent lateral shoulders, apex curved ventrad. Hypoproct posteriorly extending to level of middle of gonostylus, ventral setae small, in a patch of ca. 20 setae on each half. Cerci mesially separate. Female unknown. Discussion . M. radula is one of the few species of Manota which have a non-setose episternum 2. The other species are M. ctenophora Matile ( New Caledonia ), M. forceps Hippa & Papp ( Thailand ) , M. maorica Edwards ( New Zealand ), M. serawei Hippa (New Guinea ), M. sinepollex sp. n. ( Sumatra ), M. subforceps sp. n. ( Sumatra ), M. taedia Matile ( New Caledonia ) and M. unifurcata Lundström (Europe) . The only species that have a non-setose episternum 2 and a non-setose laterotergite are M. forceps , M. subforceps and M. unifurcata . M. radula differs from M. unifurcata e.g. by lacking the apicomesial extension and the curved sensilla on the maxillary palpomere 3, and from M. forceps and M. subforceps by having a unicolorous wing and a short wing vein R1. M. radula differs from all three species by its branched gonostylus. The unusual branched gonostylus alone is sufficient to easily recognize M. radula . The only species which may be similar is M. perlobata Hippa ( Thailand and Burma ) but its gonostylus has a long basal part with one short and two long transversely placed lobes or branches. Etymology. The name is derived from Latin, radula , scraper, referring to the scraper-like area on the mesial lobe of the gonostylus. Types . Holotype . Male, BRUNEI , Ulu Temburong , 14.ii.–9.iii.1982 , Malaise trap, M. C. Day leg. (in NHM). Paratypes . 1 male with the same data as the holotype (in NHM).
