Type locality. Vientiane, Houayang forest, Laos.

Etymology. This species is named after the great entomologist and staphylinid specialist, Alexey Solodovnikov, who was also my MSc thesis advisor.

Distribution. The species is known only from few localities in Vietnam, Laos, and Thailand. It is presumably widespread in Indochina.

Diagnosis. This species is most similar to P. nudus , P. longipenis , and P. peninsularis . From those species and all other Parachorius , it can be separated by the following combination of characters (1) protibia with apical spur reaching protarsomere 2, (2) first tooth approximately twice as wide as second tooth, (3) metatibia inner margin denticulate with relatively small teeth, (4) parameres with dorsally horn-like upper lobes.

Description. Body. Body black, length 3.9–5.0 mm. Elytra uniformly colored.

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 almost straight or sinuate anterior margin. Protibia with apical spur reaching protarsomere 2. First tooth 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, not modified. Metatibia slightly sinuate, inner margin denticulate with relatively small teeth, produced in small angle apically.

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

Aedeagus. Parameres symmetrical, with dorsally horn-like upper lobes.

Holotype. Male ( Fig. 23E View FIGURE 23 ). Profemur with sinuate anterior margin.
