Type locality. Darjeeling, India ( Parachorius globosus ); Darjeeling, India ( Heteroateuchus oberthueri )

Distribution. Northeastern India.

Diagnosis. Parachorius globosus differs from other species of Parachorius by rugose punctation of elytra, reduced wings, and pronotum being almost as long as elytra in anterior-posterior direction.

Description. Body. Body, brown, length 6–7 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 0.5– 2.0 puncture diameter(s). Pronotum in anterior-posterior direction almost as long as elytra.

Elytra. Elytra covered with dense contiguous and rugose punctures.

Wings. Wings reduced, approximately as long as 1/2 of normally developed wings.

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 almost not modified in males, approximately 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 serrate (sometimes slightly), simple, not modified. Metatibia slightly sinuate, inner margin not denticulate, produced in small angle apically.

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

Aedeagus. Parameres symmetrical, simple, apex widely rounded and inferiorly angulate.
