Tersilochus (Tersilochus) serratus Khalaim & Lee sp. n. Figs 52-61 View Figures 52–61
Description.
Female (holotype). Body length 4.0 mm. Fore wing length 2.8 mm.
Head weakly rounded and strongly narrowed behind eyes in dorsal view ( Fig. 53 View Figures 52–61 ); temple 0.72 times as long as eye width. Inner eye orbits very weakly divergent dorsally ( Fig. 52 View Figures 52–61 ). Mandible with upper tooth longer than lower tooth. Clypeus lenticular, 3.2 times as broad as long, in profile flat, finely granulate and indistinctly punctate in upper 0.7. Malar space as long as basal width of mandible. Flagellum of antenna filiform, with 21 segments ( Fig. 54 View Figures 52–61 ); all flagellomeres 1.2-1.4 times as long as broad; flagellomeres 4-6 with distinct subapical finger-shaped structures on outer surface ( Fig. 55 View Figures 52–61 ). Face, frons, vertex, and temple distinctly granulate, dull, and impunctate ( Figs 52 View Figures 52–61 , 53 View Figures 52–61 ). Mesosoma entirely granulate, dull, and impunctate; mesopleuron centrally with fine, slightly oblique striae on granulate background ( Fig. 56 View Figures 52–61 ). Notaulus absent. Foveate groove weak, with fine transvers wrinkles, oblique, situated in anterior 0.6 of mesopleuron ( Fig. 56 View Figures 52–61 ). Propodeum with rectangular basal area, which is about 1.5 times as long as broad and 0.35 times as long as apical area ( Fig. 57 View Figures 52–61 ); transverse carina with short adjacent wrinkles ( Fig. 57 View Figures 52–61 ). Propodeal spiracle adjacent to pleural carina. Apical area flat, anteriorly truncate ( Fig. 57 View Figures 52–61 ), posteriorly with transverse wrinkles. Apical longitudinal carinae well-developed, reaching transverse carina anteriorly. Fore wing ( Fig. 58 View Figures 52–61 ) with intercubitus slightly longer than abscissa of cubitus between intercubitus and second recurrent vein. First abscissa of radius somewhat longer than width of pterostigma. Metacarpus ending far from apex of fore wing. Postnervulus intercepted distinctly below middle. Hind wing with nervellus distinctly reclivous. Metasoma: first tergite almost 3.0 times as long as broad posteriorly, with petiole trapeziform in cross-section, entirely striate dorsally and laterally ( Fig. 60 View Figures 52–61 ), and with postpetiole smooth (except base) and well separated from petiole in dorsal view. Glymma deep, situated behind center of first tergite, joining by distinct furrow to ventral part of postpetiole. Second tergite distinctly transverse, 0.8 times as long as anteriorly broad ( Fig. 60 View Figures 52–61 ). Thyridial depression short, distinctly transverse ( Fig. 60 View Figures 52–61 ). Ovipositor slender, upcurved, with two distinct subapical teeth dorsally and deep depression between these teeth ( Figs 59 View Figures 52–61 , 61 View Figures 52–61 ); sheath 1.25 times as long as first tergite.
Head, mesosoma, and first tergite black; palpi, mandible (except reddish black teeth), and lower 0.3 of clypeus yellow-brown; tegula yellow. Antenna dark brown. Pterostigma brown with conspicuous white spots on its proximal and distal corners ( Fig. 58 View Figures 52–61 ). Legs brownish yellow; fore and mid coxae weakly, and hind coxa strongly darkened with brown. Metasoma behind first tergite yellow-brown ventrally and pre dominantly dark brown to brownish black laterally and dorsally; tergites 2 and 3 with narrow pale posterior band ( Fig. 59 View Figures 52–61 ).
Male. Unknown.
Comparison.
Differs from other Korean species of the genus by the combination of head weakly rounded and very strongly tapered behind eyes in dorsal view ( Fig. 53 View Figures 52–61 ), flat clypeus ( Fig. 52 View Figures 52–61 ), strongly striate dorsally first metasomal tergite ( Fig. 60 View Figures 52–61 ), and shape of the ovipositor ( Fig. 61 View Figures 52–61 ). This is the only Korean species of the genus Tersilochus that possesses an ovipositor with two distinct dorsal subapical teeth ( Fig. 61 View Figures 52–61 ) and thus belongs to the cognatus species group (correct name for the jocator species group according to Horstmann 2005); Tersilochus iracundus sp. n. and Tersilochus punctator sp. n. have ovipositors with rather weak and inconspicuous dorsal subapical teeth ( Figs 26 View Figures 23–30 , 50 View Figures 45–51 , 51 View Figures 45–51 ).
Type material.
Holotype female, South Korea, Gyeongbuk-do (GB), Cheongdo-gun, Gakbuk-myeon, Namsan-3ri, 35°41'N, 128°35'23.0"E, Malaise trap, 1-12.IV.2009, coll. J.W. Lee (YUG).
Distribution.
South Korea.
Etymology.
Named after the Latin serratus (serrated, toothed like a saw), on account of its serrate ovipositor apex.
