Diagnosis
This species is similar to Lathrolestes verticalis (Brischke, 1871) but distinguishable by combination of the following characters: clypeus not separate from face by distinct groove (Fig. 1B); mesopleuron and metasoma distinctly punctate (Fig. 1E, I); areolet of fore wing closed (Fig. 1H); area petiolaris of propodeum complete; tergites 1 and 2 entirely black; further tergites reddish (Fig. 1I).
Description
Male. Body length 7.7 mm.
Head. Matt, punctate with shallow and sparse punctures on shagreen surface (Fig. 1C). Face 1.15 × as broad as eye height, relatively flat, bulging (Fig. 1B). Clypeus not separated from face, at apex projecting anteriorly (Fig. 1B); apical margin of clypeus thick. Clypeal fovea large. Malar space 0.6 × as long as basal mandible width. Lower mandible tooth longer than upper. Occipital carina complete.
Mesosoma. Matt. Pronotum punctate with sparse punctures. Epomia absent. Mesoscutum punctate with shallow indistinct punctures, matt, with notaulus shallow (Fig. 1D). Mesopleuron distinctly and sparsely punctate with fine punctures, polished (Fig. 1E). Claws not pectinate. Fore wing with R intercepting pterostigma before its middle (Fig. 1H); areolet not petiolate; vein 2m-cu of fore wing with single bulla. Vein cu-a of hind wing slightly postfurcal, with cu-a intercepted by Cu1 below middle. Propodeum with only apical carina complete (Fig. 1F).
Metasoma. Matt, distinctly and densely punctate with shallow punctures (Fig. 1I). Tergite 1 1.5 × as long as broad apically, convex, with longitudinal dorsal carinae and medial impression (Fig. 1I). Tergite 2 rectangle (Fig. 1I). Following tergites also elongate (Fig. 1I). Parameres broad at base (Fig. 1G).
Color. Body mostly black. Scape, antennal flagellum ventrally, face entirely, temple eye posteriorly, mandible except teeth, propleurum, lateral parts of mesonotum, tegula, band in the middle of mesopleurum, fore and middle legs, hind coxa ventrally yellowish. Hind femur ventrally, hind tibia basally, metasomal starting at tergite 3 reddish. Female . Unknown.
Etymology. The name redimiculus refers to yellow band of the middle of mesopleurum.
Material examined. Holotype: male; type depository: YNU, GW, Hangrobong (Sweeping), 13.vi.1992, leg. S.M. Ryu. Paratypes: 3 males, GW, Hangrobong, (Sweeping), 13.vi.1992, leg. S.M. Ryu (YNU); 1 male, ditto, (Sweeping), leg. J.W. Lee (YNU).
