Manota iquitosensis sp. n.

Figs 10 A–C

Male. Colour. Head brown, face yellowish. Antenna including scape and pedicel brown. Clypeus and mouthparts pale yellowish. Thorax brown including the ventral part of preepisternum 2. Legs yellowish, base of hind coxa and apical third of hind femur infuscated. Wing with slightly brownish tinge; haltere yellow with brown knob. Abdomen brown. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer ones. Head. Fourth antennal flagellomere 1.8 times as long as broad. Palpal segment 3 of maxillary palpus with apicomedial thumb-like extension, with 2–3 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 about 1.3 times longer than palpomere 4. Nine strong postocular setae. Thorax. Anepisternum with 45 setae; anterior basalare and preepisternum 2 non-setose; laterotergite with 16 setae; metepisternum with 5 setae widely distributed on ventral part. Legs. Mid- and hind tibial organs absent. Wing. R1 meeting C within the basal half of the costal margin; the sclerotized part of M2 not extending to the level of the tip of R1; wing length 1.9 mm. Hypopygium. Figs 10 A–C: Sternite 9 large, lateral and posterior margins forming a contiguous arch, posterior margin slightly concave medially and extending to the level of the base of gonostyli, anterior margin with deep vshaped medial incision, the setae similar to the adjacent ventral setae of gonocoxa. The ventral medial margin of gonocoxa anteriorly transverse, posteriorly from the gonostylys obliquely longitudinal. Gonocoxa with the part posteriorly from the gonostylus unusually long, posteriorly with a small lobe bearing a transverse seta. The ventral setosity of gonocoxa unmodified, posteriorly the setae stronger. Parastylar lobe transverse, partly covered by medial part of gonocoxa, with 3 setae at posterior margin. No paraapodemal lobe identifiable. Dorsal medial margin of gonocoxa simple, convex, posteriorly combined with a lobe, bearing ca 10 megasetae on margin and on ventral side. Gonocoxa has a small posterolateral setose lobe belonging to both the dorsal and ventral sides.

General setosity on the dorsal side of gonocoxa similar to that on the ventral side. Two juxtagonostylar setae present both of which are flattened and complicatedly folded megasetae, the more ventral one with a seta-like branch and arises from a low basal body, the more dorsal one arises from a finger-like basal body that is longer than the megaseta. Gonostylus bilobed, with a short and broad basodorsal lobe and a long finger-like ventral lobe, the ventral lobe setose on both sides, the dorsal lobe non-setose. Aedeagus subtriangular, with slight lateral shoulders, the apex curved ventrad. Hypoproct extending posteriorly to the apices of gonostyli, the ventral part (sternite 10) and dorsal part clearly separated, the latter unusually narrow and posterior in position, the number of setae on the ventral part ca. 15 on each half. Cerci unusually broad, medially separate.

Female. Unknown.

Discussion. Manota iquitosensis resembles M. rara , from Costa Rica, and runs to that species in the key by Jaschhof & Hippa (2005). Manota iquitosensis differs from M. rara in having: 1) the gonostylus divided into a short dorsal and long finger-like ventral lobes (in M. rara the basal lobe is more like a bulge on the basomedial margin of the gonostylus), 2) the dorsal medial margin of the gonocoxa with a number of strong megasetae posteriorly (only one in M. rara ), and 3) sternite 9 with a widely rounded posterolateral part (angularly rounded in M. rara ).

Etymology. The name is Latin, iquitosensis , ‘of Iquitos’, referring to the type locality.

Types. Holotype. Male, PERU, Department of Loreto, Iquitos area , Mishana , 1–16.x.1998, Malaise trap A2, I. E. Sääksjärvi et al. leg. (on slide, UNSM).
