Differential diagnosis. See diagnosis of Taiwanaenidea cheni sp. nov.
Males. Length 4.2–4.7 mm, width 1.5–1.6 mm. General color (Figs 24–25) greenish or bluish metallic, antenna and leg yellowish brown, antennomeres III or IV–XI darkened. Discs of head, pronotum, and elytron smooth, without micro-reticulation. Head strongly constricted behind eye. Antenna (Fig. 30) filiform and extremely elongate, as long as body, ratio of length of antennomeres III to XI about 1.0: 1.3: 1.2: 1.1: 1.1: 1.1: 1.1: 0.9: 1.2; ratio of length to width from antennomere III to XI about 3.2: 4.3: 4.7: 4.4: 4.4: 4.4: 4.4: 4.0: 4.7. Pronotum 0.9X longer than wide, narrowed at middle. Elytra 2.0X longer than wide, parallel-sided. Tarsomeres I of front and middle legs normal. Median lobe of abdominal ventrite V rectangular, apical margin straight. Penis (Figs 32–34) elongate, widest at apical 1/4, narrowed at middle, deeply bifurcate from apical 1/4 to apex, apically tapering, apex narrowly rounded; tectum well sclerotized, apex widely rounded; apex straight in lateral view, abruptly curved at apical 1/3; endophallus with two pairs of long and curved setae, one shorter and about half of another in length, longer one directed inwards, with a small outer sclerite with two teeth; ventrally covered with one piece of dense setae, dorsally covered with one elongate tube-like sclerite.
Females. Length 5.4–6.3 mm, width 2.2–2.5 mm. Similar to male (Figs 26–27), but head slightly constricted behind eyes. Antenna (Fig. 31) as long as body; ratio of length of antennomeres III to XI about 1.0: 1.2: 1.2: 1.1: 1.1: 1.1: 1.1: 1.0: 1.2; ratio of length to width from antennomere III to XI about 3.6: 4.4: 4.4: 3.9: 3.9: 3.9: 3.9: 3.5: 4.2. Apical margin of abdominal ventrite V truncate. Gonocoxae (Fig. 35) slender, and combined together from basal 1/4 to apical 1/4, apex of each gonocoxa widely rounded, with eight long setae; widened at middle and slightly recurved; base wide. Ventrite VIII (Fig. 36) well sclerotized; apex wide, apical margin truncate; disc with three pairs of extremely long setae at sides, one row of long setae near apical margin and one row of short setae along apical margin; spiculum long. Spermathecal receptaculum (Fig. 37) strongly swollen, distinctly separated from pump; pump strongly curved; spermathecal duct slender, deeply projecting into receptaculum.
Variation. Some females have brown or blackish brown heads and yellowish brown prothoraces (Figs 28–29).
Host plant. Alnus formosana (Burkill ex Forbes & Hemsl.) Makino (Betulaceae).
Distribution. Central Taiwan (Fig. 21). Taiwanaenidea collaris is sympatric with T. strigosa in Kuanwu (Hsinchu County), Suyuan (Ilan County), Meifeng and Tsuifeng (Nantou County).
