Description.
Male
.
Body length 15.0 mm (from vertex to elytral apices), body width
4.9 mm
(conjoint width of elytral humeri).
Body black; antennae reddish brown; elytra dark reddish brown with several blackish spots.
Body densely clothed with mingled yellowish ocher, brown and black pubescence in the following manner: head, antennae, femora, tibiae (except for each apex), elytra and ventral surface with light to dark yellowish ocher and brown pubescence; pronotum, apices of tibiae and tarsi covered with blackish pubescence except for light yellowish ocher lines on pronotum; pubescence on elytral disk becoming sparser in an inverted triangular area of basal 1/3 and apical 1/5, darkened behind scutellum and in apical 1/10. Elytra provided with a pair of brownish tufts of long bristle-like hairs on basal swellings, and 4 pairs of large tufts of yellowish ocher hairs on disk and several small tufts of pale hairs in apical 3/4 of lateral sides; tibiae with black short setae near apices.
Head slightly narrower than anterior margin of pronotum; frontal disk sparsely punctured; eyes well prominent and deeply emarginated; lower lobes 0.8 times as long as width, 0.9 times as long as genae; antennal tubercles well elevated.
Antennae 0.9 times as long as body; scape swollen, thickest near middle; antennomeres 3 and 4 slightly curved; the relative ratio of each segment as follows: 1.0: 0.3: 1.5: 1.6: 1.0: 0.9: 0.8: 0.8: 0.7: 0.7: 0.7.
Pronotum cylindrical, 0.9 times as long as wide, widest near middle, weakly constricted behind middle; disk weakly convex above, with a pair of distinct tubercles near middle.
Scutellum wide, lingulate.
Elytra elongate, 2.1 times as long as wide at humeri, 3.6 times as long as pronotum, gradually tapered towards obliquely truncated apices with acute outer angles; disk with a pair of obtuse swellings associated with brownish long bristles near base, sparsely provided with punctures which are distinct in basal half, then getting smaller apically and almost disappeared in apical 1/3.
Legs with femora weakly swollen; mesotibiae with a groove near apical 1/3 of each anterior margin; relative lengths of metatarsomeres 1–3 and claws: 2.6: 1.5: 1.8: 4.1.
Male genitalia with tegmen (
Figs 9–11
) rhombic, widest near middle in dorsal view, weakly curved ventrally in lateral view; ringed part weakly expanded laterally near middle; lateral lobes thick, about 1/5 of the total length of tegmen, gently tapered apically, with an obtuse transversal ridge on each ventral side near base, evenly with minute setae on ventral surface throughout, with ¿ne setae which are mostly concentrated near apices. Median lobe (
Figs 12–14
) weakly curved in lateral view; apex acuminate in ventral view; median strut diverged from basal 3/5. Endophallus in fully inflated condition without eversion (
Fig. 14
) slightly shorter than threefold of the median lobe length, divided into BPH, MPH and APH by constriction; BHP slightly longer than the half the length of median lobe, with CS and a well developed basal swelling around CS on ventral side; MPH provided with three kinds of inflation which are a pair of lateral swellings, a triangular ventral swelling and an obtuse dorsal swelling before middle, sparsely with several ¿ne spicules which are arranged into two irregular lines on apical 1/3 of latero-dorsal side, densely with minute scaly sclerites on basal 1/3; APH undeveloped, swollen in a short plummet shape, with a single ED on dorsal side before apex.

Scale bar = 1.0 mm. Abbreviations: APH – apical phallomer; BPH – basal phallomer; CS – crescent shaped sclerites; ED – ejaculatory duct; MPH – median phallomer.
Differential diagnosis.
This new species is easily distinguishable from the other congeners (see
Figs 1–6
) by the following characteristics: pronotum with a pair of distinct tubercles on disk; elytra mostly covered with light yellowish pubescence, with brownish tufts of long bristle-like hairs on basal swellings; punctures on elytra sparse in basal half and almost disappearing in apical third.
Etymology.
The species name is dedicated to its collector, Ms. Lee Hsueh.
Distribution.
Taiwan
(known only from the
type
locality, Mt. Lala-shan). The species represents the ¿rst record of the genus
Callomecyna
in
Taiwan
