Sparedrus sasajii nom. nov.

( Fig. 5 )

Polacus longicornis Sasaji, 1985: 1 ; secondary homonym, preoccupied by Sparedrus longicornis (Iablokoff- Khnzorian, 1970): 62.

Type locality. Taiwan, Kaohsiung prov., Mt. Fengang near Liu-kui.

Type material examined. HOLOTYPE: J, ‘ Mt. Fengang near Liukuei, Kaohsing, Formosa [handwritten in Japanese letters, type locality cited according to original description], 3.iv.1980 [handwritten], H. Fujita [probable meaning; handwritten in Japanese letters] // H. Fujita Collection [printed] // HOLOTYPE, male, Polacus longicornis Sasaji, 1985 , gen. et sp. nov. [red label, handwritten]’ ( NSMT) .

Redescription. Coloration. Head including antennae sooty, mouthparts partly sienna, prothorax sooty, anterior margin narrowly sienna. Legs sooty, basal two thirds of femora and bases of tibiae narrowly rusty, ventral part of body sooty. Elytra sooty; wide, oval, mediolongitudinal sooty stripe reaching ca. two thirds of elytral length and corresponding with flattened portion of elytra ( Fig. 5 ).

Male. Eyes large and protruding, head across eyes ca. one fifth wider than pronotum, nearly parallel-sided behind eyes. Frons between eyes ca. three times narrower than maximum width of antennomere 2. Last palpomere of maxillary palpus narrowly securiform. Antenna very long, exceeding body by almost length of elytra, antennomere 3 slightly more than ten times as long as antennomere 2, antennomeres 3-10 more or less serrate with arcuate inner margin and with protruding inner lateroapical corner, antennomeres 6-11 more or less flattened dorsoventrally, more or less curved. Surface of head imbricate-punctate, matt, covered by long, semierect white pubescence forming a crest between eyes. Pronotum almost one fifth longer than wide, nearly parallel-sided, anterior margin nearly straight, anterior corners very slightly rounded, lateral margins very slightly sinuate, posterior corners obtuse, posterior margin rounded. Surface of pronotum densely verrucose, matt; disc moderately flattened before posterior margin; long, semierect white pubescence forming a central asterisk before middle and a pair of moderately sinuate lines around flattened part before base. Elytra slightly narrowing posteriorly, lateral margins very slightly sinuate, surface rather sparsely punctate, semilustrous, covered by long, recumbent white pubescence, elytral nervation absent, disc of elytra flattened in basal two thirds of their length. Last tergite by one third exceeding last sternite, apex moderately emarginate; apex of last sternite widely, arcuately emarginate. Dissection of aedeagus was not allowed.

Female unknown.

Length (J): 10.8 mm.

Distribution. Taiwan.

Comments. Sparedrus sasajii nom. nov. very probably belongs to S. longicollis species group as defined by ŠVIHLA (2006b). Its position must be verified by examination of the aedeagus.
