description: Alevonota hetzeli nov.sp. (Figs 6-10)
T y p e m a t e r i a l: Holotype ♂: ̎ TAIWAN, Hualien, Guanyuan, pine forest, sifted, 2459 m, 24°11'22''N, 121°20'22''E, 1.VIII.2018, Hetzel leg. / Holotypus ♂ Alevonota hetzeli sp. n. det. V. Assing 2019̎ (cAss).
E t y m o l o g y: This species is dedicated to Andreas Hetzel (Hildesheim), who collected the type material of both A. calliceroides and A. hetzeli.
D e s c r i p t i o n: Body length 3.9 mm; length of forebody 1.8 mm. Habitus as in Fig. 6. Coloration: head black; pronotum blackish-brown; elytra dark-brown; abdomen blackish-brown with the posterior margins of tergites III-VII and the posterior portion of tergite VIII reddish-brown; legs yellowish-brown; antennae blackish.
Head (Fig. 7) 1.1 times as broad as long, broadest across eyes; lateral contours between eyes and posterior constriction of head weakly convex, i.e., posterior angles completely obsolete; dorsal surface with fine and moderately sparse punctation, narrowly impunctate along middle; interstices with distinct microreticulation.
Eyes large and bulging, approximately as long as distance from posterior margin of eye to posterior constriction of head in dorsal view. Antenna (Fig. 8) 1.2 mm long; antennomeres IV transverse, but less than 1.5 times as broad as long, V-IX weakly transverse, X nearly as long as broad, and XI elongate, slightly longer than the combined length of IX and X.
Pronotum (Fig. 7) as broad as long and 1.1 times as broad as head, broadest approximately in the middle; lateral margins weakly convex in dorsal view; pubescence of midline directed posteriad; punctation similar to that of head, but slightly denser; interstices with distinct microreticulation.
Elytra (Fig. 7) approximately as long as pronotum; punctation dense and fine, but more distinct than that of head and pronotum; interstices with microreticulation. Hind wings fully developed.
Abdomen narrower than elytra; tergites III-V with rather deep anterior impressions; punctation moderately sparse and fine, but distinct; interstices with distinct microsculpture predominantly composed of short transverse meshes; posterior margin of tergite VII with palisade fringe.
♂: posterior margins of tergite VIII and sternite VIII strongly convex; median lobe of aedeagus (Figs 9-10) 0.39 mm long and slender.
♀: unknown.
C o m p a r a t i v e n o t e s: Alevonota hetzeli is readily distinguished from A. calliceroides and A. taiwanensis by much smaller, and from A. laevigata PACE, 2009 (Taiwan: Taichung) by distinctly larger body size alone. It differs from the two similarly sized A. taiwanica and A. longicornis PACE, 2009 as follows:
from A. taiwanica (male unknown) by much more bulging eyes, distinctly less transverse antennomeres IV-X, and a differently shaped head (A. taiwanica: lateral contours behind eyes somewhat parallel for some distance);
from A. longicornis by distinctly transverse antennomeres IV (A. longicornis: antenno-
meres IV approximately as long as broad), larger and more convex eyes, and by the shape of the aedeagus.
For illustrations of A. taiwanica and A. longicornis see PACE (2009).
D i s t r i b u t i o n: The type locality and the circumstances of collection are identical to those of A. calliceroides.
