Diversity of Manota Williston (Diptera: Mycetophilidae) in a Malaysian rainforest: description of twenty-seven new sympatric species Author Hippa, Heikki text Zootaxa 2006 2006-03-30 1161 1 1 49 https://biotaxa.org/Zootaxa/article/view/zootaxa.1161.1.1 journal article 10.11646/zootaxa.1161.1.1 1175­5334 5058330 A1C3B9CA-8A9D-4B41-9F9D-81BFC31CFB2D Manota transversa sp. n. ( Figs. 9C, D, E ; 10C ) A small­sized Manota . Male. Head. Flagellomere 4, Fig. 9C . Maxillary palpus with palpomere 3 bearing 4–5 apically expanded curved sensilla; palpomere 4 with parasegment. Thorax. Anepisternum setose. Anterior basalare non­setose. Preepisternum 2 setose. Laterotergite non­setose. Episternum 3 setose. Wing . Length 1.4–1.5 mm . Wing membrane dorsally with few setae on posterior margin. Sc distally of h non­setose. Setae indicating A1 not observed with certainty. Hypopygium ( Figs. 9D, E ; 10C ). Sternite 9 large, extending posteriorly nearly to halfway along ventral length of gonocoxa, laterally sharply delimited, posterior margin indistinct, medially confluent with more posterior membranous part with transverse straight margin, setae similar to adjacent ventral setae of gonocoxa. Dorsomesial margin of gonocoxa simple, few stronger setae at apicomesial rounded corner, in position III 2 sigmoid or curved simple megasetae arising from common long basal body; gonocoxa apicolaterally with long, tapering, mesially setose, subtriangular lobe that does not extend posteriorly as far as apex of gonostylus. Gonostylus elongate curved quadrangular in outline, convex on lateral margin, concave on mesial margin, obliquely truncated on apical margin, at apicomesial angle on dorsal side with 2 transverse parallel rows of strong setae ( Fig. 10C ). Parastylar lobe present, directed anteriad, with 2 or 3 apical setae. Tegmen short and broad, subtriangular but with marked lateral shoulders. Setae on sternite 10 in single row or partly double row on each half, close to sides of apical part of tegmen. Female and preimaginal stages unknown. Discussion Manota transversa is similar to M. procera and M. calcarata . For the distinguishing characters from M. calcarata , see under that species. Manota transversa and M. procera differ as follows: in M. transversa the gonostylus is narrower or less expanded at the apex, the dorsal setae at the apicomesial corner are in two short transverse rows, not in longitudinal rows or without clear arrangement, and the apicolateral lobe of the gonocoxa is short, posteriorly not extending to the level of the apex of the gonostylus as it does in M. procera . The difference in the shape of the apicolateral lobe of the gonocoxa between the two species ( Figs. 9B, E ) may also be significant. Types Holotype .
