Manota forceps sp. n.

( Figs 6 A, B)

Body dark brown, almost black, length ca. 2.9 mm, wing length 2.24 mm.

Male. Head. Flagellomere 4 1.6 times as long as broad with 0.03 mm long trichia. Postocular setae (11) black, moderately long but rather thick. Thorax. Anepisternum non-setose. Anterior basalare non-setose. Setae of preepisternum 2 not observed. Laterotergite non-setose. Setae of episternum 3 not observed. Scutellum with 5 evenly long (0.20 mm) black marginal setae. Mid and hind femora black, all tibiae and tarsi darkened. Wing. Wing membrane brown, particularly darkened on the radial section, dorsally without setae at posterior margin. Sc distally of h very short, non-setose. Ratio of visible sections of veins M1 and M2 65/136. Hypopygium ( Figs 6 A, B). Sternite 9 sub-oval, about half the ventral length of gonocoxa, laterally sharply demarcated, basally with a shallow emargination, setae similar to ventral setae of gonocoxa. Gonocoxa with angulate mesial margin. Parastylar lobe well exposed, almost as long as gonocoxa and directed posteriad, basally weakly separated from gonocoxa, with a group of subapical setae. Paraapodemal lobe very small, only partly exposed in ventral view. Dorsal mesial margin of gonocoxa with a broad posteriorly directed, apically angulate setose lobe. Two juxtagonostylar setae present: a curved megaseta and a thinner seta arising from a flattened, unusually long basal body, which is ca. four times as long as the megaseta. Gonostylus unusually long, longer than gonocoxa, ventrally setose, dorsally almost non-setose, the setae on the mesial margin forming a conspicuous fringe. Tegmen elongate-triangular, with sloping lateral shoulders. Hypoproct large and broad, extending slightly more posteriad than gonocoxa, with only 3–4 ventral setae on each side. Cerci short, medially united near base.

Female unknown.

Discussion. Manota forceps is distinguished from all other previously described Manota in which the male is known by its gonostylus, which is longer than the gonocoxa instead of being much shorter. The unusually long, posteriorly directed parastylar lobe is also unique. The dorsal armature of the gonocoxa has a resemblance to the New Zealand M. maorica Edwards by having a similar, very long basal body to the juxtagonostylar megasetae and by having a similar large setose lobe in a more dorsal position. M. maorica differs by having the gonostylus short, scarcely more than half the length of the gonocoxa, and which is composed of several lobes, and by having a short parastylar lobe. M. forceps differs from most species of Manota by lacking the thumb-like apicomesial extension on palpomere 3 as well as the curved sensilla located on that extension. One species that is similar in this respect, M. whiteleyi , was recently described from South Africa by Jaschhof and Mostovski (2006), but its hypopygium is abundantly different and resembles that of the Afrotropical M. furcata Söli , M. serrata Söli and M. sespinea Söli. The non-setose anepisternum of M. forceps is also a rare character in Manota . M. maorica ( New Zealand), M. taedia Matile ( New Caledonia), M. ctenophora Matile ( New Caledonia) and M. unifurcata Lundström (Europe) are similar in this respect, but there are several species in the Afrotropical region and a few species in the Neotropical region in which this character has not been studied.
