Parachorius lannathai Hanboonsong & Masumoto, 2001: 138   (new synonymy)

Type locality. India or. [ eastern India ] ( Parachorius thomsoni   ); Maesa Valley Chiang Mai   , Thailand ( Parachorius lannathai   )

Taxonomic notes. Parachorius lannathai   described from Thailand is synonymized with P. thomsoni   based on external morphology and the shape of aedeagus.

Distribution. Eastern India, Myanmar, Thailand, and Laos.

Diagnosis. The species is most similar to P. fungorum   and P. hookeri   . It differs from them by the following combination of characters (1) metafemoral posterior margin with two distinct denticles of which the apical denticle is spur-like, produced; (2) parameres simple, apex slightly rounded forming triangle.

Description. Body. Body black or dark brown, length 6.5–9.0 mm. Elytra uniformly colored.

Head. Clypeus with two indistinct teeth, outer margin of each tooth not 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 medially produced in angle or 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 as wide as second tooth; first and second teeth distinctly separated from each other; first distinctly separated from denticles located between first and second teeth. Metafemoral posterior margin not serrate, with two distinct denticles of which apical denticle is spur-like, produced. Metatibia slightly sinuate, inner margin not denticulate, excavated apically.

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

Aedeagus. Parameres symmetrical, simple; apex slightly rounded, forming triangle.
