Manota hirsuta View in CoL sp. n.

( Figs 12 View FIGURE 12 A, B)

A small-sized Manota .

Male. Coloration. Pale brown, frons, vertex and occiput darker brown, mouthparts and legs slightly paler than thorax but apices of coxae, trochanters and base and apex of femur on leg 3 darker brown, wing unicolorous, hyaline, pale yellowish-brown, knob of haltere darker. Head. Antennal flagellomere 4 in the single specimen present only on one side and is seen in oblique ventral view but is not illustrated, in lateral view apparently similar to Fig. 10 View FIGURE 10 C. Palpomere 3 of maxillary palpus with apicomesial extension, with 3 apically expanded curved sensilla; palpomere 4 with parasegment. Thorax. Pleural setosity pattern similar to Fig. 1 View FIGURE 1 C: anepisternum setose, with 24 setae; anterior basalare setose, with 8 setae; the setosity of preepisternum 2 not observed; laterotergite setose, with 33 setae; episternum 3 setose, with ca. 7 setae ca. 7 setae. Wing. Length 1.5 mm. Hypopygium ( Figs 12 View FIGURE 12 A, B). Sternite 9 laterally fused with gonocoxa except for the extreme posterior part, posterior margin straight, at the level of the base of gonostylus, anterior margin shallowly notched, setosity similar to ventral setosity of gonocoxa. Parastylar lobe well exposed, large, longer than broad, with 5 setae directed obliquely posteriad. Paraapodemal lobe not exposed when hypopygium is viewed ventrally. Dorsal mesial margin of gonocoxa with an aggregation of long setae near the middle. More posteriorly the margin curves laterad, forming a weak lobe on the ventral side of which there is another lobe with blunt setae on the margin and on the ventral surface. There is also one indistinct setose lobe posteriorly from these two lobes. The juxtagonostylar setae cannot be clearly observed in the single specimen: there seems to be one flattened, pale, transparent megaseta arising from a strong but rather short basal body. Gonostylus short, almost round, apicomesially with two prominent setae, the thicker one of which is broken on both sides in the single specimen, apicodorsally with thick short setae diverging from the other scanty setosity. Tegmen with rather strong sloping lateral shoulders. Hypoproct extending further posteriad than the apex of gonostylus, with ca. 12 scattered ventral setae on each side. Cerci separate.

Female and preimaginal stages unknown.

Discussion. M. hirsuta is similar to M. spathula and M. subspathula . It is distinguished from both e.g. by the following characters: 1) the posterior margin of stergite 9 is straight, not convex or notched, 2) the parastylar lobe is longer than basally broad, not as long as broad or shorter, 3) there is an aggregation of long setae at the middle of the dorsal mesial margin of gonocoxa, 4) the lobe with blunt setae on the same margin is placed far into the apical (posterior) half, not in the middle, and 5) the gonostylus is short, almost round, instead of elongated and with distinct apicolateral and apicomesial corners.

These three species are similar to two Neotropical species: M. squamulata Jaschhof and Hippa and M. major Jaschhof and Hippa but it is difficult to find any common characters for distinguishing them. M. spathula and M. subspathula with the slightly bilobed gonostylus resemble M. squamulata but M. squamulata has the apical lobes more distinct and it has the gonostylus shorter and broader, almost as in M. hirsuta . Furthermore, M. spatula is distinguished by its greatly expanded juxtagonostylar megaseta and M. subspathula by its notched apical margin of tergite 9. M. hirsuta differs e.g. by the aggregation of long setae at the middle of the dorsal mesial margin of the gonostylus and by having the lobe with blunt setae on the same margin more posterior in position, the Neotropical species resembling M. spathula and M. subspathula in this respect; the gonostylus is similar to M. major but in that species the two long apicomesial setae are equally thick.

M. hirsuta , M. spathula and M. subspathula are also similar to those Oriental and Afrotropical species which have tergite 9 extending posteriorly to the level of the base of the gonostyli and laterally fused with the gonocoxa. In the Oriental region these species are M. biloba Hippa , M. dentata Hippa and Papp , M. heptacantha Hippa , M. simplex Hippa and M. clausa Hippa , and in the Afrotropical region at least M. flavipes (Enderlein) , M. serrata Söli , M. sespinea Söli and M. teocchi Matile , but there are several Afrotropical species in which the exact character of the tergite 9 is not known. M. dentata and M. biloba , M. heptacantha , and all the Afrotropical species differ from M. hirsuta , M. spathula and M. subspathula by having megasetae on the dorsal mesial margin of gonocoxa. M. heptacantha in which the megasetae are relatively weak and may resemble the blunt-ended setae in the New Guinean species does not have these setae on a prominent lobe that is exposed in dorsal view. In M. simplex and M. ulu Hippa there is a dorsal mesial lobe with sharp setae and the lobe is covered by the more dorsal part of the gonocoxa. All the Oriental species have one fine juxtagonostylar seta unlike the New Guinea species, which have a megaseta.
