Type locality. Kuatun , Fújiàn Province, China.

Distribution. The species is known from southeast China (Fújiàn Province), Laos, and Vietnam. The locality in Fújiàn province is the northernmost one among all the species in the genus Parachorius . Given the large extent of occurrence, this species is probably widespread in Indochina and southern China.

Taxonomic notes. The known localities of this species are quite distantly located from each other, which is uncommon for the members of Parachorius . Therefore, this distributional pattern may suggest that P. fukiensis represents a complex of similar species and requires additional material and a more detailed study to resolve the issue.

Diagnosis. This species is most similar to P. bolavensis . It differs from P. bolavensis in aedeagal parameres emarginate superiorly (i.e., dorsally in lateral view, Fig. 8A–C ), rounded aedeagal apex, and metafemoral posterior margin not rimmed. Parachorius fukiensis can be separated from the rest of Parachorius species by the shape of aedeagus.

Description. Body. Body black, length 3.5–4.6 mm. Elytra uniformly colored, mostly dark.

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

Pronotum. Pronotum rounded laterally. Frontal angles rounded. Disc covered with punctures separated by 1–2 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 anterior margin produced in angle medially or with almost straight or sinuate anterior margin. Protibia with apical spur approximately reaching middle of protarsomere 3. First tooth normal, notably modified in males, approximately twice as wide as second tooth; first and second teeth distinctly separated from each other; first tooth distinctly separated from denticles located between first and second teeth. Metafemoral posterior margin not serrate, simple, or dilated in apical third of metafemur and produced in angle. Metatibia slightly sinuate, inner margin not denticulate, produced in small angle apically.

Metasternum. Transverse basal ridge of metasternum reduced and extremely short.

Aedeagus. Parameres symmetrical, emarginate superiorly (i.e., dorsally in lateral view, Fig. 8A–C ), apex rounded.
