Males (Figs 5 A–5C). Length 6.2–6.7 mm; width 3.7–3.9 mm. Antenna (Fig. 6 A) long, filiform, about 1.1x longer than body, length ratios of antennomeres I–XI 1.0: 0.3: 0.7: 1.0: 0.9: 0.8: 0.8: 0.8: 0.8: 0.8: 0.9, length to width ratios of antennomeres I–XI 3.3: 1.8: 3.1: 4.6: 4.4: 4.4: 4.5: 5.5: 6.1: 5.4: 7.0. Elytra apically weakly broadened; about 1.2-1.3x longer than wide; surface with sparse, coarse punctures and several indistinct longitudinal ridges. Apical margin of last abdominal ventrite with two well developed incisions. Penis (Figs 6 C– 6D) elongate, about 5.1x longer than wide, gradually narrowed towards middle, apex lanceolate, strongly curved in lateral view; endophallic sclerite long, about 0.8x as long as penis, slender and longitudinal, apical margin rounded, with dense short hairs along lateral margin at middle, bifurcate at basal 1/6.
Females (Figs 5 D–5F). Length 6.9–7.3 mm, width 4.5–4.7 mm. Antenna (Fig. 6 B) long, filiform, as long as body, length ratios of antennomeres I–XI 1.0: 0.3: 0.7: 0.9: 0.9: 0.8: 0.8: 0.8: 0.8: 0.8: 0.8, length to width ratios of antennomeres I–XI 4.0: 1.5: 3.1: 4.6: 4.9: 5.5: 5.3: 5.6: 6.5: 5.8: 7.1. Elytra strongly broadened apically; about 1.0–1.1x longer than wide; surface with sparse, fine punctures and several indistinct longitudinal ridges. Apical margin of last abdominal ventrite subtruncate. Gonocoxae (Fig. 6 E) longitudinal and narrow, 3.2x longer than wide, conjoined from base to middle, slightly narrowed in apical 1/3, apices rounded, each gonocoxa with eight elongate setae. Ventrite VIII (Fig. 6 F) with only apical area and spiculum sclerotized; with dense elongate setae inside apical sclerotized area, apical margin rounded; spiculum elongate and broad. Receptacle of spermatheca (Fig. 6 G) slender, as wide as pump, hardly separated from pump; pump broad and strongly curved, apex broadly rounded, apex with transverse, broad sclerite (Fig. 6 H), size variable; proximal spermathecal duct hardly separated from receptacle, apically narrowed.
Differential diagnosis. See diagnosis of Shairella cheni sp. nov.
Host plants. Strobilanthes flexicaulis Hayata (Acanthaceae) and Hemiboea bicornuta (Hayata) Ohwi (Gesneriaceae).
Etymology. The new species is dedicated to Mr. Yi-Ting Chung, who collected the type specimens.
Distribution. Only known from the type locality (Fig. 3 A).
