Eurydema sp.

Diagnosis. Head declined, orange oval spot in the center of verteX, basal half of mandibular plates yelloW-White. Basal angle of thoratic pleuron With a black arc-shaped strip. Body size, shape, and color pattern similar to those of E. maracandica , but coneXivum concolorous significantly different and the center of abdomen Without obvious black spots. Male genitalia also different; posterolateral angles of pygophore apeX oval ear-shaped ( Figs. 9 A and B), paramere With a Wide base, apeX sharp ( Fig. 9 C), vesical very long ( Figs. 9 D and E).

Description. Body oblong, White-yelloW, shining and coarsely punctate With differently shaped spots.

Head. Declined, verteX black, eXcept a yelloWish spot in the center. Basal half of mandibular plates WhiteyelloW. Mandibular plates slightly longer than clypeus and convergent anteriorly. Ocelli red, situated distinctly posteriad to the level of posterior margin of eyes, relatively near the eyes; eyes broWn. Head beneath WhiteyelloWish. Antenna black, segment II longer than segment III, segment IV subequal to segment V. Rostrum black, apeX reaching the anterior margins of mesocoXae.

Thorax. Pronotum conveX, White-yelloWish, coarsely and unevenly punctate, four large black spots arranged equidistantly in a nearly transverse line medially. Discally With transverse oval-shaped narroW blackish callosities. Anterior margin concave, With a conspicuous smooth collar. Anterolateral margin smooth, With an inconspicuous ridge edge. Lateral angle rounded, Weakly produced, seldom surpassing the base of Wing. Scutellum subtriangular, White-yelloWish, eXcept a black irregular spot in the center of basal half, With a small black spot at each lateral side of scutellum. Hemelytron With clavus black. Corium unevenly yelloWish, With an L-shaped black spot and a small black spot at the subapeX. EXocorium White-yelloWish With tWo black spots at the middle and apical part, respectively. Membranes infuscate, surpassing the apeX of abdomen, out margin transparent. Thoracic sternum incompletely yelloWish, leaving a black spot near the mesosterum, pleurum of mesothoracic segment also WhiteyelloW, eXcept a black arc-shape strip in basal angle. Legs concolorous With body color, eXcept the femora scattered With black spots, tWo terminals of tibia black, tarsi black.

Abdomen. Oval, concolorous With body color, no conspicuous black spots in the center. Stigmata black.

Male genitalia. Pygophore broWn With tWo pair posterolateral angles, the larger angle ear-shaped, apeX deeply concave; the smaller angle angular, situated beside the larger one; dorsoposterior rim semicircle; ventroposterior rim sinuated ( Figs. 10 A and B). Paramere C-shaped, strongly tapered, apeX sharp, base Wide and broad ( Fig. 10 C). Aedeagus simple, With one pair of basolateral conjunctival lobes, apices not bifurcate and strongly sclerotized; apical conjunctival lobe absent. Vesica long, stretched out from the venter of median penial plates and subequal to median plates ( Figs. 10 D and E).

Distribution. China: Xinjiang Province.

Remark. Eurydema sp. similar to E. maracandica , but the spots of head, scutellum and abdomen very different. Male genitalia also different. Due to the lack of related references, especially for alien species, We cannot determine it as a neW species, so, named Eurydema sp.
