Manota fimbriata sp. n.

( Figs 11 A, B, C)

Male. Colour. Head pale brown, frons and occiput darker brown, mouthparts pale yellowish. Thorax pale brown, posterior part of scutum medially and scutellum darker brown, preepisternum 2 ventrally paler yellowish. Legs pale yellowish, femur 3 apparently infuscated on apical third but the character is very difficult to estimate in the single specimen. Wing unicolorous yellowish-brown; haltere yellowish-brown with dark brown knob. Abdomen brown, as dark as scutellum. All the setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 11 A. Palpomere 3 of maxillary palpus with apicomesial extension, with at least 3 apically expanded curved sensilla but the exact number not possible to see in the single specimen; palpomere 4 with parasegment. Number of postocular setae 10. Thorax. Anepisternum non-setose, anterior basalare non-setose, preepisternum 2 non-setose, laterotergite non-setose, episternum 3 setose, with 5 setae. Wing. Length 1.8 mm. Hypopygium, Figs 11 B and C: Sternite 9 unusually broad, its length about one-third of the ventral length of gonocoxa, lateral margin sharply delimited, posterior margin slightly convex, anterior margin not incised or notched, apparently transversely straight but the character is difficult to see because the area is membraneous, the setae of sternite 9 present only posteriorly and those at margin unusually strong. Ventral mesial margin of gonocoxa simple. At the corner between the posterior margin of sternite 9 and mesial margin of gonocoxa with an elongate globular lobe bearing a number of short curved setae, which may be the paraapodemal lobe; it seems to have a membraneous connection with the unusually basally situated gonocoxal apodeme. More posteriorly, near the gonostylus, with an elongated lobe with 3 long setae which is probably the parastylar lobe. The proportions in the dorsal side of gonocoxa are unusual, the gonocoxal apodemes with associated structures being shifted to an unusually anterior position. Posterior two-thirds of gonocoxa with a fringe of very long setae near the mesial margin. One juxtagonostylar seta present, which is an unmodified megaseta arising from a low basal body. Gonostylus small and narrow with rather strong setae. The gonostylus is rather high in the dorso-ventral direction, which cannot be seen in the drawing. Tegmen with a long narrow apical half and broad subtriangular basal half in which the basalmost part is narrowed. Hypoproct long and narrow, but not reaching base of gonostylus, with some 15 setae on each half. Cerci medially separate, unusually anterior in position.

Female unknown.

Discussion. M. fimbriata is one of the few species of Manota which have a non-setose anepisternum. The other similar species are the Palaearctic M. unifurcata Lundström and the four Oceanian species M. maorica Edwards , M. ctenophora Matile , M. taedia Matile and M. serawei Hippa. In other respects M. fimbriata is not similar to any of these. Because of the very anterior placement of the gonostylar apodemes and tegmen as well as the constricted basalmost part of the latter, M. fimbriata is reminiscent of M. globigera Hippa and M. parvistylata sp. n. but otherwise there is no special similarity between the species. In M. fimbriata the anterior parts of gonocoxa are shortened and the posterior parts elongated which leads to unusual proportions, e.g. the great distance between parastylar lobe and paraapodemal lobe. M. fimbriata is readily distinguished from any described Manota by the fringe of very long setae at the dorsal mesial margin of gonocoxa, covering about two-thirds of the whole gonocoxal length.
