( Figs 1E–F View FIGURE 1 , 4 View FIGURE 4 , 5 View FIGURE 5 : square)

Diagnosis. Adult of Sindosium chungbukicum can be distinguished from other Sindosium species by weakly developed mesoventral process and long, oval, assymetrically caved spermatheca with puffed out basal tip.

Description. Body length 0.97–0.99 mm, width 0.52–0.54 mm; oval, convex; color light brown, dorsum punctuate with pale yellow pubescence. Antennomeres I–II reddish brown, III–XI dusky yellow ( Figs. 1E–F View FIGURE 1 ).

Head. Broad, rounded; weakly, finely, very sparsely punctuate. Eyes large; distance between eyes in ventral view 0.19 mm. Antennal length 0.40 mm; Antennomeres I–II large, thicker than others; III short, cone-shaped; IV–V long, weakly dilated distally; VI–VII lengthy oval; VIII oval, short, stout; IX–XI clavate, basal half of seta darker; IX ovoid, basal half swollen; X basal two thirds swollen; XI ovoid ( Fig. 4A View FIGURE 4 ).

Thorax. Pronotum length 0.26 mm, width 0.45 mm; widest slightly behind middle, basally narrowed; lateral margin curved, flattened and serrate; surface shining, evenly punctuate except for a small central patch; posterior margin almost straight, somewhat wider than anterior margin. Scutellum equilaterally triangular ( Figs. 4B–C View FIGURE 4 ).

Wings. Elytra length 0.64 mm, long, complete; evenly punctuate with pubescence; lateral margin anteriorly with 4–5 denticules, each with seta; posterior margin rounded ( Fig. 4E View FIGURE 4 ). Hindwing blade wide, membranous; anterior petiolar margin with one distinct seta, posterior margin setose on distal third ( Fig. 4D View FIGURE 4 ).

Meso-, Metaventrite. Mesoventrite with anterior collar and keel; keel somewhat slender; laterally of mesocoxae, mesopleural [anterior] suture straight, directed obliquely anterad, metaventral [posterior] line slightly cave, distally obtusely angled, directed posterad. Mesoventrite medially shorter than metaventrite ( Fig. 4G View FIGURE 4 ).

Abdomen. Abdominal sternite I anteromedially with prominent knob fitting to metaventral [intermetacoxal] condyle ( Figs. 4G, I View FIGURE 4 ). Female tergite X small, semicircular ( Fig. 4H View FIGURE 4 ).

Legs. Procoxae contiguous. Mesocoxae separated by faint process. Metacoxae short, wide, almost contiguous; separated only by an intermetacoxal condyle ( Figs. 4B, G View FIGURE 4 ).

Male genitalia. unknown.

Female genitalia. Spermatheca length 0.17 mm, width 0.091 mm; ovally elongate, almost two times longer than wide, invaginated basally; short chord proximally of invagination; base rounded, mushroom-shaped part short and stout, apex puffed out ( Fig. 4J View FIGURE 4 ).
