Etymology The specific epithet is derived from the Latin evangelium (“good news”), referring to fact that its discovery was good news for the team; the specific name is also in memory of the anime “Neon Genesis Evangelion”, which is one of the greatest animes in Japanese history and had a strong impact on Japanese popular culture.

Description Coloration Body and legs nearly black. Antennae dark brown to black. Mandibles yellowish brown. Body closely covered with pale pubescence; anterior margin of clypeus, antennae, elytra and legs fringed with pale bristles. Male ( Fig. 2P ) HEAD. Nearly as long as wide; vertex faintly hollowed, depressed along apical margin of clypeus and in lateral areas before eyes; surface densely and finely punctate and semilustrous; anterior margin of clypeus arcuate and faintly indented in middle; eyes not so large, globular and slightly prominent, ratio of eye diameter to interocular space 1:5.3; terminal labial palpomeres rounded ax-shaped; terminal maxillary palpomeres rounded ax-shaped; antennae filiform, extending to elytral midlength; antennomere I clavate, II short and a little expanded apicad, III to XI subcylindrical, all antennomeres without groove, ratio of antennomere lengths: 16: 10: 15.5:20.5: 20.5: 20.5: 20.5: 20: 20:18.5: 23. PRONOTUM. Subquadrate, about 0.90 times as wide as head, nearly as long as wide; anterior and posterior margins moderately arcuate; lateral margins feebly arcuate; anterior angles rounded; posterior angles obtuse; dorsum convex in postero-lateral and hollowed in antero-lateral areas; medio-longitudinal groove distinct in posterior half; surface smooth and semilustrous. Scutellum triangular with rounded apex. ELYTRA. Conjointly about 1.6 times as wide as pronotum, about 2.6 times as long as wide, sides subparallel; surface densely and finely punctate and moderately lustrous. LEGS. Moderately slender; femora mostly straight; tibiae mostly straight, with basal part feebly arcuate; claws simple. AEDEAGUS ( Fig. 5 A–C). Ventral process expanded and rounded apically, apex curved inwards, basal part broad and extending inwards onto ventral side; dorsal plate of each paramere as long as ventral process, broad and slightly narrowed apically, apical margin rounded, with some hairs on it, concave on inner margin. Laterophyse very short, with truncated apex, invisible in lateral view. Inner sac swollen, lengthened behind, and somewhat shorter than tegmen. Body length 4.50–5.75 mm ( holotype : 5.50 mm ); width 0.80–1.25 mm (1.25). Female ( Fig. 2Q ) Similar to male. Body wider than in male. Eyes smaller than in male, ratio of eye diameter to interocular space 1:6.4. Antennae distinctly shorter than in male, barely exceeding humeri, ratio of antennomere lengths: 13: 10: 14: 16:15: 16: 14: 16: 14: 13:16.5. PRONOTUM. About 0.95 times as wide as head, about 0.95 times as long as wide. Elytra conjointly about 1.6 times as wide as pronotum, about 2.6 times as long as wide. Claws simple. Abdominal ventrite VII widely emarginate on each side of terminal margin, forming subtriangular lateral lobes, median lobe indistinct in some specimens ( Fig. 6I ). FEMALE GENITALIA ( Fig. 6J ). Vagina stout and rounded, abruptly extended apically as long and thick duct; diverticulum and spermathecal duct arising from apex of long duct of vagina; diverticulum moderately thin and spiral, longer than spermathecal duct; spermatheca provided with thin spiral tube, tube slightly longer than diverticulum; accessory gland thin, shorter than spermatheca. Body length 4.75–6.50 mm ; width 1.50–2.25 mm . Variation Lateral sides of pronotum somewhat converging or diverging posteriorly; body lusterless. Remarks This species is widely distributed in the Central Mountain Range at mid to high altitude except one specimen collected from the Kenting Park, which is at low altitude. It appears mainly from spring to summer according to label data. Distribution ( Fig. 8 ) Taiwan (endemic).
