description: Dryophilocoris kerzhneri Jung et Yasunaga sp. nov.
(Figs. 1–12)
Diagnosis. Distinguished from its congeners by the relatively small body size (5~ 6 mm in length), the yellow exocorium (Figs. 1–2) and the sharp and long vesica of male genitalia (Fig. 9).
Etymology. Named after the late Dr. I. M. Kerzhner in recognition of his extensive knowledge of the Heteroptera.
Description. Male: Body elongate, parallel-sided; dorsal surface almost bare. Head shiny dark brown, almost glabrous (Figs.1–2), with a yellow basal transverse carina on vertex. Antennae dark brown; segment I usually dark brown; segment II brown to dark brown, sometimes with paler base; lengths of segment I–IV: 0.42–0.45, 1.65–1.74, 0.77–0.78, 0.31–0.33. Pronotum entirely mat and pilose, with three yellow longitudinal stripes; calli dark brown with a yellow longitudinal stripe; scutellum yellow, smooth; mesoscutum dark brown; pleura widely grayish brown, pruinose; propleuron dark brown, with yellow margin; ostiolar peritreme and evaporatorium well-developed (Figs. 5–8). Hemelytra dark brown, somewhat shagreened, sparsely pubescent; embolium, basal apex of cuneus, and anterior or sometimes whole lateral margin of corium yellow (Figs. 1–2); membrane dark grayish brown, with apical parts of veins and a spot along apex of cuneus pale. Coxae and legs yellow; apical parts of femora sometimes tinged with orange brown; tibial spines pale brown, short; tarsi brown; pretarsus with well-developed parempodia and pulvilli (Fig. 4); lengths of hind femur, tibia and tarsus: 1.48–1.54, 2.12–2.25, 0.28–0.35. Abdomen entirely yellowish brown. Genitalia (Figs. 9–10): Ventral surface of genital segment moderately excavated at apex, left paramere long, apical part of left paramere of toothed shape; right paramere broad, vesica with main 3 branches, mesial branch of vesica toothed apically. Female: Similar to male but larger (see Dimensions below). Genitalia (Fig. 11–12): Kstructure well-developed, narrow at basal part; anterior wall with large sclerotized rings, thin-rimmed, oval shape.
Dimensions (in mm). Male/female: body length 5.31–5.45/5.44–5.48; head width including eyes 0.78– 0.81/0.79–0.84; vertex width 0.32–0.38/0.38–0.41; rostral length 1.34–1.41/1.35–1.41; mesial pronotal length 0.74–0.81/0.75–0.89; basal pronotal width 1.33–1.41/1.41–4.45; width across hemelytra 1.41–1.48/1.55– 1.71.
Distribution. South Korea (Central).
