(Figs 7–8)
Type locality. Taiwan: Kaoshiung County, Tienchih (Ŧè), 23°16’37”N, 120°55’01”E, 2200 m.
Types (n= 27). Holotype ♂ (TARI), Kaohsiung: Tienchih (Ŧè), 17.V.2015, leg. B.- X. Guo. Paratypes: 3♂, 2♀ (TARI), same data as holotype; 10♂, 9♀ (TARI, RBCN), Kueiku (Ñê), 11.VI.2015, leg. C.- F. Lee; 2♀ (TARI), Kuanshanyakou (DƜ ḄŊ), 30.VII.2015, leg. C.- F. Lee.
Males (Figs 7 A–7C). Length 4.3–4.6 mm; width 2.5–2.7 mm. Antenna (Fig. 8 A) long, filiform, about 1.2x longer than body, length ratios of antennomeres I–XI 1.0: 0.4: 0.8: 0.9: 0.8: 0.8: 0.8: 0.8: 0.8: 0.7: 0.8, length to width ratios of antennomeres I–XI 3.2: 1.9: 3.6: 4.2: 3.6: 4.1: 4.0: 4.1: 4.5: 4.1: 4.8. Elytra strongly broadened apically; about 1.1x longer than wide; surface with sparse, fine punctures. Apical margin of last abdominal ventrite with two well developed incisions. Penis (Figs 8 C–8D) elongate, about 6.9x longer than wide, parallel-sided, apically tapering from apical 1/6, strongly curved in lateral view; endophallic sclerite short, about 0.5x as long as penis, slender and longitudinal, apical margin medially depressed, with dense short hairs along lateral margin at apical 1/3, bifurcate at basal 1/4.
Females (Figs 7 D–7F). Length 5.0– 5.3 mm, width 3.2–3.3 mm. Antenna extremely long, filiform, as long as body, length ratios of antennomeres I–XI 1.0: 0.3: 0.7: 0.7: 0.7: 0.7: 0.8: 0.7: 0.7: 0.7: 0.7, length to width ratios of antennomeres I–XI 3.5: 1.5: 2.9: 3.3: 4.1: 4.0: 4.4: 3.9: 4.1: 3.9: 4.3. Elytra strongly widened apically; about 1.0–1.1x longer than wide; surface with sparse, fine punctures. Apical margin of last abdominal ventrite truncate. Gonocoxae (Fig. 8 E) longitudinal and narrow, 3.8x longer than wide, conjoined from base to middle, slightly narrowed at apical 1/3, apices rounded, each gonocoxa with eight elongate setae. Ventrite VIII (Fig. 8 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. 8 G) slender, as wide as pump, hardly separated from pump; pump broad and strongly curved, apex broadly rounded, apex with transverse, short sclerite, size variable (Figs 8 H– 8I); proximal spermathecal duct hardly separated from receptacle, apically narrowed.
Differential diagnosis. See diagnosis of Shairella aeneipennis Chûjô.
Host plant. Clinopodium laxiflorum var. taiwanianum Hsieh & Huang (Labiatae).
Etymology. The new species is dedicated to Mr. Bo-Xin Guo, who collected the type specimens.
Distribution. Vicinity along western half of South Cross-Island Highway (ĦḂḦR) (Fig. 3 A).
