Abstract: Zanchius marmoratus Zou, 1987 Figs 1 G, H, 2 B, G – I, N, 3 E, F Zanchius marmoratus Zou, 1987: 297, 299; Liu and Zheng 2014: 216. Zanchius zoui Zheng & Liu, 1993: 17 (syn. by Lin 2005: 189; Liu and Zheng 2014: 216). Specimen examined. Vietnam • 7 ♂♂ 10 ♀♀, Hoa Trung Lake, Hoa Lien Ward, Hoa Vang District, Da Nang City, 16.0891°N, 108.0425°E, 90 m altitude, on Mallotus barbatus, 2.xi.2024, J. Kim (ZCDTU) (DTUHMM 0023–0039). Diagnosis. Recognized by yellowish-brown body with bluish-green spots, covered with short, silky pubescence; head mostly pale brown, except for greenish posterior margin; antennae pale brown, with dark stripes and annulations, subequal to body length; first segment with dark stripe on outer lateral margin, longer than vertex width; second segment pale brown, with two dark annulations on subbasal and subapical parts; third segment pale brown with dark base; pronotum partly green and pale brown, lateral and posterior parts pale; scutellum mostly green, with pale apices; hemelytra subhyaline, yellowish pale brown, with bluish-green markings, covered with short silvery pubescence; clavus mostly green by having a large, greenish marking; corium mostly yellowish pale brown with three or four markings, inner and posterior margin greenish; cuneus mostly subhyaline, middle and apical part green; legs mostly yellowish brown; all femora yellowish brown with lateral bluish-green stripe; pygophore asymmetrical and posterior margin rounded; parameres scythe-shaped, endosoma with two sclerotized curved and long spiculi (Fig. 2 G – I, N). Description. Male: see the original description by Zou (1987). Genitalia: pygophore asymmetrical with rounded posterior margin (Fig. 2 B); left paramere scythe-shaped, sensory lobe broadened basally, hypophysis slightly broadened, rounded, its apex sharp (Fig. 2 G, H); right paramere curved subapically, hypophysis with small projection medial inner part (Fig. 2 I); endosoma with two sclerotized curved spiculi; spicule I (sp I) long and thin, vertically curved, gradually tapered from base; spicule II (sp II) shorter than sp I, extremely curved, rapidly tapered, its base remarkably broad (Fig. 2 N). Female: coloration: as in male. Surface and vestiture: as in male. Structure: as in male, except for long antennae, more than body length. Genitalia: sclerotized rings (sr) of dorsal labiate plate narrow, with large and rounded serrate areas (Fig. 3 E); posterior wall with simple interramal lobe (irl), irl contiguous, slightly expanded from interramal sclerite (irs), outer margin of irl sinuate (Fig. 3 F). Host. Mallotus barbatus (Euphorbiaceae) *. Distribution. Vietnam (Central) *, China (Southeast, Southwest), Taiwan. Remarks. Zou (1987) included drawings of the left paramere in two different orientations in the original description of this species. However, based on our direct examination of multiple specimens, we conclude that these drawings were horizontally flipped. Our description aligns with the illustrations provided by Lin (2005).
