Moissonia yasunagai sp. nov.

Figures: 1, 3F–J

Diagnosis. Recognized by yellowish green dorsum; numerous dark spots on pronotum; usually grayish (or brown) pleura, coxae, trochanters, base of pro- and mesofemora, and entire metafemora; short and stout apical processes of endosoma ( Fig. 3F) comparatively curved; apical outgrowth on inner margin of right paramere ( Fig. 3I); structure of left paramere as in figure 3G; and thin rimmed, oval shaped sclerotized rings of bursa copulatrix ( Fig. 3J).

Description. Male. Body small, oval. COLORATION ( Fig. 1): Generally greenish yellow, and shiny; head and pronotum greenish yellow, mesoscutum and scutellum brown or dark brown with yellow lateral margins and mesial region of first one, and head, pronotum, mesoscutum and scutellum provided with numerous dark brown spots; hemelytron hyaline, apices of clavus and exocorium, inner mesial margin of cuneus with distinct dark brown spots, inner base and apex of cuneus with obscure spots, membrane pale and shagreen. Ventral side of the body grayish (or brownish) and abdomen green. Antenna blackish brown, segment I yellowish brown, with brown rings on base and apex ventrally, segment II yellowish brown except base and apical one quarter dark brown and extreme base and apex pale, and segment III and IV dark brown with pale extreme base and apex of segment III. Labium pale brown with dark apex. All coxae and trochanters grayish (or brownish); larger basal part of pro- and mesofemora grayish and apex pale, metafemora entirely grayish (or brown tinged with red apically); all tibia pale with black spots. SURFACE AND VESTITURE: Dorsum furnished with uniformly distributed simple black, sub-erect setae and sericeous setae; ventrally with shining pale pubescences. STRUCTURE: Head projecting ventrally; labium short, reaching apex of mesocoxae; pronotum convex, lateral margins curved. GENITALIA ( Figs. 3F–I): Endosoma U-shaped, apical process short, slender and curved, 5–6 notches subtending secondary gonopore ( Fig. 3F). Phallotheca as in figure 3H. Left paramere as in figure 3 G. Right paramere with small, triangular protuberances at inner margin apically ( Fig. 3I).

Female. Not significantly different from male in color and vestiture except slightly wider abdomen. GENITA- LIA ( Fig. 3J): Sclerotized rings comparatively thin rimmed and posteriorly oval; and dorsal labiate plate with semisclerotized, inverted U-shaped structure at middle.

Measurements. (♂ / ♀). (1/ 5): Body length 3.07/ 3.17–3.41; head width across eyes 0.74/ 0.77–0.80; vertex width 0.36/ 0.38–0.42; lengths of antennal segments I–IV: 0.20, 0.85, 0.55, 0.37/ 0.19–0.22, 0.79–0.87, 0.50–0.55, 0.43–0.45; total length of labium 0.94/ 0.97–1.07; mesal pronotal length 0.50/ 0.55–0.59; basal pronotal width 1.16/ 1.26–1.32; width across hemelytron 1.34/ 1.46–1.51; and lengths of metafemur, tibia and tarsus: 1.02, 1.54, 0.37/ 0.99–1.09, 1.56–1.67, 0.40–0.42.

Specimens examined. Holotype (♂): South Korea: Gyeonggi-do, Suwon-si, SNU Arboretum, 20.viii.2009, on Kalopanax septemlobus (Thunb. Ex Murray) (Araliaceae) , Ram Keshari Duwal and Sunghoon Jung (SNU). Paratypes: 6♀, same collection data as holotype (SNU).

Etymology. Named in honor of Dr. Tomohide Yasunaga, who has provided many contribution to clarify the Asian Miridae fauna.

Distribution. Korea (South).

Discussion. This new species is similar in general appearance to Moissonia terai ( Duwal et al. 2010b) and M. befui ( Yasunaga 1999) , from which it can be distinguished by the grayish (in some brown) pleura, coxae and femora, and distinctly different genital structures ( Figs. 3F–J).

Adults were collected from the inflorescences of Kalopanax septemlobus (Thunb. ex Murray) (Araliaceae) .
