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).
