Manota limulata Hippa, Kurina & Sääksjärvi, 2017, sp. n.

Manota limulata sp. n.

Figs 11 A–C

Male. Colour. Head brown, face somewhat paler to yellow. Antenna including scape and pedicel light brown. Clypeus and mouthparts pale yellowish. Thorax yellow to light brown, medial part of scutum and scutellum somewhat darker. Legs yellowish, apical fifth of hind femur infuscated. Wing with brownish tinge; haltere yellow with blackish brown knob. Abdomen light brown, medial 2/3 of tergites dark brown. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer ones. Head. Fourth antennal flagellomere 1.6 times as long as broad. Palpal segment 3 of maxillary palpus with apicomedial thumb-like extension, with three strong and apically curved sensilla; palpomere 4 with parasegment; palpomere 5 about 1.3 times longer than palpomere 4. Ten strong postocular setae. Thorax. Anepisternum with 36–50 setae; anterior basalare, preepisternum 2 and laterotergite non-setose; metepisternum with 13–19 setae along its margin. 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 1.5–1.7 mm. Hypopygium. Figs 11 A–C: Sternite 9 laterally fused with gonocoxa, the posterior margin deeply concave in the middle, not extending to the middle between the anterior margin of gonocoxa and the base of gonostylus, anterior margin deeply incised medially, the setae similar to the adjacent ventral setae of gonocoxa. Ventral medial margin of gonocoxa between sternite 9 and gonostylus simple, convex, laterally from the gonostylus with a long finger-like setose lobe, the posterolateral part drawn into a setose lobe; the ventral setae of gonocoxa unmodified, rather short, posterolaterally with a couple of longer setae. Parastylar lobe membranous, covered by the medial part of gonocoxa, with one seta. No paraapodemal lobe identifiable. Inside the gonocoxa there is a structure with oblique transverse ridges, drawn on the left side in Fig. 11 A. Dorsal medial margin of gonocoxa partly indistinct because it is confluent with the more ventral and medial lobes consisting of 1) a more anterior one with a finger-like and a plate-like part, the former with one, the latter with two unmodified megasetae, and 2) a more posterior finger-like lobe with two megasetae and a couple of short setae. The general setosity on the dorsal side of gonocoxa similar to the ventral one. Two juxtagonostylar setae present as flattened megasetae, the more ventral one with a seta-like branch, both megasetae arising from a common basal body that is slightly longer than the megasetae. Anteriorly from the juxtagonostylar megasetae there is a curved lobe with ca. 5 fine apical setae and in a more anterior position a strong megaseta. Gonostylus elongate subquadrangular, basomedial corner slightly produced with one very long and one short seta, apicomedial corner forming a small tooth, medial margin bears a short seta near apex. Aedeagus elongate, the apex curved ventrally, in Fig. 11 C the medially visible part is the ejaculatory apodeme. Hypoproct extending posteriorly to the middle of gonostylus, with rounded posterolateral shoulders, the number of ventral setae (sternite 10) ca. 40 on each half. Cerci medially separate.

Female. Unknown.

Discussion. The non-setose laterotergite, gonocoxa laterally fused to sternite 9, membranous parastylar lobe, posterolateral lobe of the gonocoxal, and megasetae bearing lobes at the dorsal medial margin of the gonocoxa place M. limulata with several other Neotropical species, viz. M. arenalensis, M. incisa, M. eximia, M. montivaga, M. vexillifera, M. corcovado, M. diversiseta, M. acuminata and M. limonensis. Manota limulata is distinguished from all the known similar species by the setosity of the cercus and hypoproct that is unusually dense and short (reminiscent somewhat of setosity on the hypoproct of M. limonensis) and in having a long, apically setose, lobe posteriorly on the ventral side of gonocoxa. In M. limulata, the organ inside the gonocoxa with transverse ridges or a washboard-like surface is not observed in any other Manota, but the character can easily be missed.

Etymology. The name is Latin, limulata, ‘with a little scraper’, referring to the small scraper- or washboardlike structure in the hypopygium.
