Figs. 3 A–F
Male. Colour. Head brown, face paler brown. Antenna light brown. Clypeus light brown, mouthparts pale yellowish. Thorax dark yellow, scutum brownish. Legs yellowish, femur 2 very faintly infuscated at base, femur 3 faintly infuscated at base and clearly infuscated on apical fourth. Wing pale brown; haltere yellow with brown knob. Abdomen brownish, sternites paler than tergites. All setosity pale, yellowish or brownish. Head. Antennal flagellomere 4, Fig. 3 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 3 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 ca. 1.2 times longer than palpomere 4. Number of strong postocular setae 9–10. Thorax. Anepisternum setose, with 44–63 setae; anterior basalare non-setose; preepisternum 2 non-setose; laterotergite setose, with 14–17 setae, episternum 3 setose, with 11–18 setae. Legs. Mid and hind tibial organs absent. Wing. R1 meeting C well on the basal half of the costal margin; the sclerotized part of M2 extending to the level of the tip of R1; wing length 2.0– 2.2 mm. Hypopygium. Figs. 1 B–F: Sternite 9 trapezoidal, lateral margin free, posterior margin transverse, extending to middle of gonocoxa, anterior margin deeply incised, the setae similar to the adjacent ventral setae of gonocoxa. Ventral mesial margin of gonocoxa angled; posterolateral part of gonocoxa drawn into a broad curved lobe; ventral setosity of gonocoxa unmodified. Parastylar lobe sclerotized, broadly oval, with two setae. No paraapodemal lobe observable. Dorsal mesial margin of gonocoxa simple but somewhat lobe-like produced mesiad at the middle. Number of juxtagonostylar setae two, both similar, strongly modified megasetae with a flattened and expanded basal part which has an angular impression from some views, both megasetae are arising from separate but basally united basal bodies which are about half the length of megasetae. At the dorsal mesial margin of gonocoxa there is anteriorly from the juxtagonostylar megasetae an aggregation of strong setae and narrow blunted megasetae on a plate-like lobe. Posteriorly from the juxtagonostylar setae there is a strong seta deviating from other setosity and arising from a small basal body. Otherwise the dorsal setae of gonocoxa are similar to those on the ventral side. Gonostylus elongate-oval, with a long strong seta at the middle of mesial margin, with four strong short setae at apicolateral margin and without any additional setosity. Aedeagus elongate-subtriangular, with concave lateral sides, with associated membranous parts the details of which are not discernible, apex straight, not curved ventrad. Hypoproct large, posteriorly extending over the apices of gonostyli, the number of ventral setae (sternite 10) ca. 20 on each half. Cerci mesially separate. Tergite 9 unusually well developed, with distinct anterior, lateral and posterior margins.
Female. Unknown.
Discussion. The non-setose anterior basalare, the setose laterotergite and the delimited lateral margin of tergite 9 group Mantoa anfracta together with M. spinosa Jaschhof & Hippa, M. bihamata Jaschhof & Hippa, M. caribica Jaschhof & Hippa, M. incisa Jaschhof & Hippa, M. micula sp. n., M. penicillata Jaschhof & Hippa and M. rara Jaschhof & Hippa but it is not especially similar to any of them. It is distinguished from all these species, as well as from any other Neotropical Manota, by having a well-developed tergite 9 and a strong long seta at the middle of the mesial margin of the gonostylus. In contrast, M. caribica and M. incisa have a similar seta situating near the apex of the gonostylus. In M. caribica the ventral surface of the gonostylus is richly setose while it is non-setose in M. anfracta. In M. incisa the gonostylus is subtriangular while it is elongate-oval in M. anfracta. See also discussion under M. micula.
Etymology. The name is Latin, anfracta, winding, referring to the winding juxtagonostylar megasetae.
