Type locality. Goenoeng Tangkoeban [ Gunung Trangkuban , West Java].

Etymology. The name reflects close similarity of this species with P. javanus .

Distribution. West Java.

Taxonomic notes. This species is most closely related to P. javanus from which it can be separated by the shape of the parameres. All other previous records of P. javanus (except the holotype) have to be attributed to P. pseudojavanus , which is substantially more frequent in the collections.

Diagnosis. This species is most closely related to P. javanus . It can be separated from P. javanus and all other Parachorius by the following combination of characters (1) parameres medially narrowed (in lateral view), apically acute, (2) protibia with first tooth not noticeably modified in males, approximately as wide as second tooth.

Description. Body. Body reddish brown or rarely dark brown, length 6–7 mm. Elytra uniformly colored.

Head. Clypeus with two distinctly produced teeth, their outer margin not notched basally.

Pronotum. Pronotum rounded laterally. Frontal angles rounded. Disc covered with punctures separated by 1–4 puncture diameter(s). Pronotum in anterior-posterior direction notably shorter than elytra.

Elytra. Elytra covered with sparse punctures.

Wings. Wings normally developed.

Legs. Profemora with almost straight or sinuate anterior margin. Protibia with apical spur approximately reaching middle of protarsomere 3. First tooth almost not modified in males, approximately twice as wide as second tooth; first and second teeth distinctly separated from each other; first tooth normal, distinctly separated from denticles located between first and second teeth. Metafemoral posterior margin not serrate, simple, not modified. Metatibia slightly sinuate, inner margin not denticulate, straight, not produced apically.

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

Aedeagus. Parameres symmetrical, medially narrowed (in lateral view), apically acute.

Holotype. Male ( Fig. 20C ). Body reddish brown. Profemur with sinuate anterior margin.
