description: Manota cristata sp. n.
(Figs 10 A, B, C)
Male. Colour. Head pale brown, frons, vertex and occiput darker brown, mouthparts pale yellowish. Thorax brown, pro- and mesothoracic pleura paler brown. Legs pale yellowish, trochanter and femur 2 infuscated, femur 3 infuscated at base on apical third. Wing unicolorous pale brown; haltere pale brown with dark brown knob. Abdomen brown. All the setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 10 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 3 apically expanded curved sensilla; palpomere 4 with parasegment. Number of postocular setae 12. Thorax. Anepisternum setose, with 27 setae, anterior basalare non-setose, preepisternum 2 setose, with 7 setae, laterotergite non-setose, episternum 3 setose, in the single specimen 1 seta is visible at the middle near ventral margin, about posterior third is covered by haltere preventing visibility of possible additional setae. Wing. Length 2.0 mm. Hypopygium, Figs 10 B and C: Sternite 9 about one-half of the ventral length of gonocoxa, lateral margin sharply delimited, contiguous around the narrow convex posterior margin, anterior margin deeply incised, the setae similar to the ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple, slightly angular at lateral margin of sternite 9. Parastylar lobe large, broad, with two setae at mesial margin. Paraapodemal lobe distinct and exposed in ventral view. Dorsal mesial margin of gonocoxa anteriorly (basally) simple, posteriorly (apically) with a large plate-like lobe with a number of mostly bluntended megasetae on mesial margin and on ventral side. Two juxtagonostylar setae present, one a strong but otherwise unmodified seta, the other a strong apically flattened and expanded megaseta, the setae arising from a low, indistinct, common basal body. Gonostylus parallel-sided, but slightly angularly curved at middle, the ventral setae strong, in apical, lateral and mesial groups, the latter forming a comb-like row, the dorsal side of gonostylus with a subapical lobe with a fringe of rather weak marginal setae, otherwise the dorsal side nonsetose. Tegmen subtriangular, with lateral shoulders. Hypoproct extending posteriorly to middle of gonostylus, with some 25 setae on each half, the two anteriormost setae on each side unusually long. Cerci medially separate.
Female unknown.
Discussion. M. cristata is not similar to any other described Manota. It is readily distinguished e.g. by the slightly angled gonostylus with a comb-like row of setae on the ventral surface. The presence of two conspicuous long setae anteriorly on each half of the hypoproct is also a unique character. Only M. perissochaeta Hippa from New Guinea and the Solomon Islands is reminiscent, but it has only one seta on each side. Otherwise M. cristata and M. perissochaeta are not similar. In the Oriental fauna M. cristata is unique in having a laterally well delimited sternite 9 in combination with a long row of blunt megasetae at the dorsal mesial margin of gonocoxa. Such species occur in the Afrotropical and Neotropical regions, but otherwise they are greatly dissimilar.
