(Figs 38–51)
Type locality. Taitung county, Hsiangyang (№№), 23°14’N, 120°59’E, 2300 m.
Type material (n= 14). Holotype ♂ (TARI): “ Taiwan: Taitung (18712) / Hsiangyang (№№) / 01.IV.2011, leg. J.-C. Chen [p, w]”. Paratypes: 1♂ (TARI), same as holotype but with code number “18173”; 1♂, 2♀♀: “ Taiwan: Taitung / Hsiangyang (№№) / 28.III.2014, leg. W.-C. Huang [p, w]” (TARI); 1♀: “ Taiwan: Taitung (#25185) / Hsiangyang (№№) / 29.III.2014, leg. J.-C. Chen [p, w]” (TARI); 1♀: “ Taiwan: Chiayi (#27306) / Tzuchung [Dd] / 08.V.2015, leg. J.-C. Chen [p, w]” (TARI); 1♀: “ Taiwan: Taichung / Pilu [sª] / 22.IV.2015, leg. C.-F. Lee [p, w]” (TARI); 1♀: “ TAIWAN: Hualien, Guanyuan (DZffi), alt. / 2200~ 2300m, 07.V.2006, / 24°11’12”N 121°20’00”E, leg. Y.-F. Hsu [p, w]” (TARI); 5♀♀: “ Taiwan: Kaoshiung (#26840–26844) / Tienchih (⋏E) / 01.IV.2015, leg. C.-F. Lee [p, w]” (TARI, RBCN).
Differential diagnosis. Taiwanaenidea jungchangi sp. nov., is similar to T. strigosa with micro-reticulation on head and pronotum, but T. jungchangi sp. nov. has shining elytra that lacks micro-reticulation. This is different from T. strigosa which has micro-reticulation on the elytra. In addition, the aedeagus of T. jungchangi sp. nov. shows a number of differences from that of T. strigosa including the dorsally hook-like apices of aedeagus (straight apices in T. strigosa), endophallus with baso-lateral apophyses and short dorsal tube-like sclerite (lacking basolateral apophyses and long dorsal tube-like structure in T. strigosa), dorsally covered without any sclerite (short sclerite with two teeth in T. strigosa); two lateral, short, curved sclerites (sclerite lateral, elongate with two tapering apices in T. strigosa); absence of basal sclerite (presence of basal flat sclerite in T. strigosa).
Males. Length 3.8–4.5 mm, width 1.4–1.6 mm. General color (Figs 38–39) bluish bronze, antenna and leg yellowish brown, sometimes antenna darkened. Discs of head and pronotum with micro-reticulation. Head strongly constricted behind eye. Antenna (Fig. 44) filiform and 0.9X long as body, ratio of length of antennomeres III to XI about 1.0: 1.4: 1.1: 1.0: 1.1: 1.2: 1.2: 1.1: 1.4; ratio of length to width from antennomere III to XI about 3.4: 4.4: 3.5: 3.2: 3.4: 3.7: 3.7: 3.6: 4.1. Pronotum as long as wide, narrowed at middle. Elytra 1.9X longer than wide, parallel-sided. Tarsomeres I of front and middle legs swollen. Median lobe of abdominal ventrite V rectangular, apical margin slightly concave. Penis (Figs 46–48) elongate, widest at apical 1/4, narrowed at basal 2/ 5, deeply bifurcate from apical 1/4 to apex, apically tapering, apex acute and curved upwards; tectum well sclerotized, apex widely rounded; apex straight in lateral view, abruptly curved at apical 1/3; endophallus with one short, longitudinal, tube-like sclerite, with baso-laeral apophyses; laterally covered with two short setae, one much longer than the other, apex hook-like; ventrally covered with one flat sclerite.
Females. Length 4.8–5.2 mm, width 1.8–2.0 mm. Similar to male (Figs 40–41), but head slightly constricted behind eyes. Antenna (Fig. 45) 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: 1.0: 1.4; ratio of length to width from antennomere III to XI about 3.5: 4.6: 3.9: 3.9: 4.0: 4.0: 3.9: 3.7: 4.6. Apical margin of abdominal ventrite V truncate. Gonocoxae (Fig. 49) 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; base wide. Ventrite VIII (Fig. 50) well sclerotized; apex wide, apical margin rounded; disc with three extremely long setae at each side, one row of long setae near apical margin and one row of short setae along apical margin; spiculum long. Spermathecal receptaculum (Fig. 51) strongly swollen, distinctly separated from pump; pump strongly curved; spermathecal duct slender, deeply projecting into receptaculum.
Variation. One female has yellowish bronze body but with dark brown head except frontal area and antenna (Figs 42–43).
Host plant. Alnus formosana (Burkill ex Forbes & Hemsl.) Makino (Betulaceae).
Distribution. Central and south Taiwan (Fig. 22). Taiwanaenidea jungchangi sp. nov. is a rare but widespread species. It is sympatric with T. strigosa in Kuanyuan (Hualien County).
Etymology. This new species is named after Mr. Jung-Chang Chen, who is a member of TCRT and the first to collect this new species.
