The specimens are provided with type labels accordingly.  
D e s c r i p t i o n: Macropterous male: Coloration of head, pronotum, scutellum, corium and membrane of hemelytra and appendages dark brown, yellowish spottled are deltg II-VI, tergite VII; ptg VIII, the lateral margins of pronotum; apex of femora and median part of tibiae are also predominantly yellowish; surface of body and appendages with fine granulation.  
Head: Slightly longer than wide (1.0 / 0.90), clypeus shorter than anteriorly produced finger-like genae, those reaching 1/2 of antennal segment I; antenniferous lobes divaricating with acute apex; antennae 2.28 times as long as width of head (2.05 / 0.90), length of antennal segments I / II / III / IV = 0.50 / 0.35 / 0.75 / 0.45; segments II-IV with conspicuous long erect setae on ventral side; eyes oval inserted in head, postocular lobes with acute tubercle reaching outer margin of eyes, then strongly converging posteriorly to constricted neck; rostrum arising from a slit-like atrium, shorter than head, rostral groove open posteriorly.  
Pronotum: 2.28 times as wide as long (2.05 / 0.90), collar ringlike and carinate, lateral margins subparallel on posterior lobe, then recessed and converging to rounded anterolateral angles, surface of anterior lobe with two conical elevations at middle.  
Scutellum: Triangular, wider than long (1.15 / 1.0), lateral margins carinate, surface with a cross-like elevation.  
Abdomen: Lateral margins subparallel, posterolateral angles of deltg II-VI slightly produced, those of tergite VII truncate and directed posteriorly; deltg II-III not fused; hemelytra covering tergal plate, laterally confined by a carina, reaching 1/2 of tergite VII, irregular veins developed; spiracles II-VI ventral, VII-VIII lateral and visible from above; pygophore wider than long, truncate posteriorly, dorsal rim with with bicarinate elevation; paratergites VIII slender, club shaped, produced over apex of pygophore.  
Female: Habitus as male; paratergite VIII bilobate, produced posteriorly, bicuspidate tergites IX and X as long as ptg VIII. Venter. Sternite VI with a semi - circular median excision for the reception of split sternite VII.  
Measurements: Male, length 6.4mm; length of antennae 2.05; width of abdomen 2.40; Female. Length 6.5mm; length of antennae 1.95; length of antennal segments I / II / III / IV = 0.50 / 0.35 / 0.70 / 0.40; head length / width 1.0 / 0.85; pronotum l / w 1.0 / 2.15; scutellum l / w 1.05 / 1.20; width of abdomen 2.55.  
E t y m o l o g y: The specific epithet refers to the unusual long pilosity on ventral side of antennal segments II-IV.  
 N o t e: From the description and the figured holotype of Usingerida longiceps KORMILEV, 1977 from Borneo, it was suspected, that this might represent the new species. Jim Boom, Bishop Museum Honolulu, USA was kind enough to submit images of the holotype preserved at Bishop Museum. Comparison proved now that U. longiceps is a distinct different taxon.
