Differential diagnosis. See diagnosis of Taiwanaenidea jungchangi sp. nov.
Males. Length 3.5–3.8 mm, width 1.1–1.3 mm. General color (Figs 52–53) bluish bronze, antenna and leg brown or dark brown. Discs of head, pronotum, and elytron with micro-reticulation. Head strongly constricted behind eye. Antenna (Fig. 58) filiform and slender, as long as body, ratio of length of antennomeres III to XI about 1.0: 1.4: 1.3: 1.1: 1.2: 1.2: 1.3: 1.2: 1.5; ratio of length to width from antennomere III to XI about 2.4: 3.5: 3.2: 2.8: 3.1: 3.1: 3.2: 3.0: 3.8. Pronotum 0.9X longer than wide, narrowed at middle. Elytra 2.0–2.1X longer than wide, parallel-sided. Tarsomeres I of front and middle legs swollen. Median lobe of abdominal ventrite V rectangular, apical margin slight concave. Penis (Figs 60–62) elongate, widest at apical 1/3, narrowed at basal 1/3, deeply bifurcate from apical 1/4 to apex, apically tapering, apex narrowly rounded; tectum well sclerotized, apical tapering; apex straight in lateral view, abruptly curved at apical 1/3; endophallus with one large, longitudinal, tubelike sclerite, laterally covered with two long setae, basally combined together, one much longer than the other; dorso-laterally covered with one transverse sclerite and with two teeth.
Females. Length 4.5–5.3 mm, width 1.6–1.8 mm. Similar to male, but with yellowish bronze color (Figs 56– 57), head slightly constricted behind eyes. Antenna 0.8X as long as body; ratio of length of antennomeres III to XI about 1.0: 1.3: 1.1: 1.1: 1.1: 1.1: 1.1: 1.1: 1.4; ratio of length to width from antennomere III to XI about 2.7: 3.2: 3.1: 2.9: 2.9: 3.0: 3.0: 2.9: 3.8. Apical margin of abdominal ventrite V truncate. Gonocoxae (Fig. 63) slender, and combined together from basal 1/3 to apical 1/5, apex of each gonocoxa widely rounded, with eight long setae; abruptly widened at basal 1/3, slightly recurved; base wide. Ventrite VIII (Fig. 64) well sclerotized; apex wide, apical margin rounded; disc with two or three extremely long setae at each side, two long setae near apical margin and one row of short setae along apical margin; spiculum long. Spermathecal receptaculum (Fig. 65) strongly swollen, distinctly separated from pump; pump strongly curved; spermathecal duct slender, deeply projecting into receptaculum.
Variation. Females collected from Nantou County and some of them from Hualien have darkened color (Fig. 55) or same color as males (Fig. 54).
Host plants. Alnus formosana (Burkill ex Forbes & Hemsl.) Makino (Betulaceae), Fagus hayatae Palib. ex Hayata (Fagaceae), Pasania harlandii (Hance) Oerst. (Fagaceae), and P. hancei (Benth.) Schottky (Fagaceae).
Distribution. North and central Taiwan (Fig. 23). Taiwanaenidea strigosa is sympatric with T. collaris in Kuanwu (Hsinchu County), Suyuan (Ilan County), Meifeng and Tsuifeng (Nantou County); with T. strigosa in Kuanyuan (Hualien County).
