Type locality. Hewanshan [Hewangshan, Nantou Hsien, Taiwan].

Distribution. This species is endemic to Taiwan where it is only known from two specimens collected in type locality and Fushan botanical garden.

Taxonomic notes. Since only two specimens were examined (only one of them was male), it was not possible to assess the intraspecific variation. Presumably male specific characters such as the shape of the metafemoral posterior margin may be variable and dilated in similar way as in other species of the genus.

Diagnosis. This species differs from the other Parachorius species by its parameres elongate and rounded apically.

Description. Body. Body black, length 5.5 mm. Elytra uniformly colored.

Head. Clypeus with two teeth, outer margin of each tooth slightly notched basally.

Pronotum. Pronotum rounded laterally. Frontal angles rounded. Disc covered with punctures separated by 1.0– 1.5 puncture diameter(s). Pronotum in anterior-posterior direction notably shorter than elytra.

Elytra. Elytra covered with sparse punctures.

Wings. Wings normally developed.

Legs. Profemur with almost straight or sinuate anterior margin. Protibia with apical spur reaching protarsomere 2. First tooth notably modified in males, spatulate, bent downward and notably larger than second tooth with which it nearly merged; first tooth distinctly separated from denticles located between first and second teeth. Metafemoral posterior margin serrate, simple, not modified. Metatibia slightly sinuate, produced in small angle apically, inner margin denticulate with relatively small teeth.

Metasternum. Transverse basal ridge of metasternum long, at least 1/5 of mesocoxa length.

Aedeagus. Parameres symmetrical, elongate, and rounded apically.

Material examined. Holotype: Taiwan: 1 female, " Holotype Cassolus gotoi Masumoto / Hewanshan Date: 20.VI.1985 [Hewangshan, Nantou Hsien] Luo Chinchih leg", 23°48.7'N, 120°55.1'E ( NSMT). 1 male, Fushan Botanical Garden, 24°45'N, 121°36'E, on 7–8/v/2004, (K. Masumoto) ( NSMT).
