Type locality. Taiwan: Taitung County, Motien (=Ŧ), 23°11’35”N, 121°01’24”E, 1500 m.
Types (n= 54). Holotype ♂ (TARI), Taitung: Motien (=Ŧ), 20.VI.2011, leg. C.- F. Lee. Paratypes: 24♂, 8♀ (TARI, RBCN), same data as holotype; 3♂ (TARI), Liyuan (Mḋ), 23.VI.2010, leg. M.- H. Tsou; 1♂ (TARI), same locality, 3.X.2010, leg. M.- H. Tsou; 2♂, 3♀ (TARI), same locality, 19.VI.2013, leg. C.- F. Lee; 8♂, 4♀ (TARI), same locality, 24.VII.2013, leg. C.- F. Lee.
Males. Length 4.6–5.1 mm; width 2.7–3.1 mm. Antenna (Fig. 9 A) long, filiform, about 1.3x longer than body, length ratios of antennomeres I–XI 1.0: 0.4: 0.8: 0.9: 0.9: 0.9: 0.9: 0.8: 0.9: 0.8: 0.9, length to width ratios of antennomeres I–XI 3.3: 1.8: 3.2: 3.7: 4.0: 4.2: 4.2: 4.5: 5.0: 4.8: 5.2. Elytra apically, moderately broadened; about 1.2x longer than wide; surface with sparse, fine punctures. Apical margin of last abdominal ventrite with two well developed incisions. Penis (Figs 9 C–9D) elongate, about 5.3x longer than wide, parallel-sided, apex lanceolate, moderately curved in lateral view; endophallic sclerite long, about 0.7x as long as penis, slender and longitudinal, apically tapering, with dense short hairs along lateral margin in apical 1/4, bifurcate at basal 1/4.
Females. Length 5.4–6.4 mm, width 3.5–3.9 mm. Antenna (Fig. 9 B) long, filiform, 1.2x longer than body, length ratios of antennomeres I–XI 1.0: 0.4: 0.7: 0.9: 0.9: 0.8: 0.9: 0.8: 0.8: 0.7: 0.9, length to width ratios of antennomeres I–XI 3.6: 1.2: 2.9: 4.1: 4.4: 4.7: 4.8: 5.8: 5.7: 5.2: 6.1. Elytra strongly broadened apically; about 1.1x longer than wide; surface with sparse, fine punctures. Apical margin of last abdominal ventrite slightly convex at middle (Fig. 9 G). Gonocoxae (Fig. 9 E) longitudinal and broad, 3.0x longer than wide, conjoined from base to middle, slightly narrowed at apical 1/3, apices rounded, each gonocoxa with seven or eight elongate setae. Ventrite VIII (Fig. 9 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. 9 K) slender, as wide as pump, hardly separated from pump; pump broad, strongly curved, apex broadly rounded, apex with transverse, short sclerite, size extremely variable (Figs 9 H–9J); 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. This new species is named after the type locality.
