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 View FIGURES 24 – 29 ) 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 View FIGURES 30 – 37 ) 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 View FIGURES 30 – 37 ) 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 View FIGURES 24 – 29 ), but head slightly constricted behind eyes. Antenna ( Fig. 31 View FIGURES 30 – 37 ) 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 View FIGURES 30 – 37 ) 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 View FIGURES 30 – 37 ) 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 View FIGURES 30 – 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 View FIGURES 24 – 29 ).

Host plant. Alnus formosana (Burkill ex Forbes & Hemsl.) Makino (Betulaceae) .

Distribution. Central Taiwan ( Fig. 21 View FIGURES 20 – 23 ). Taiwanaenidea collaris is sympatric with T. strigosa in Kuanwu (Hsinchu County), Suyuan (Ilan County), Meifeng and Tsuifeng (Nantou County).
