Orthogonius perakicus Tian & Deuve, 2007: Tian and Deuve 2007: 239.

Type material.

Length: 14.0 mm; width: 5.5 mm. Habitus as in Fig. 3A.

Diagnosis.

Elytra and sides of pronotum yellowish brown, head dark brown, pronotum light dark brown on disc; head as long as wide, clypeus smooth, front margin of labrum slightly emarginated; mentum bisetose; pronotum strongly transverse, PW/PL = 1.62; lateral expanded margins narrow and reflexed throughout, evenly widened; elytra well-bordered at base, elongate ovate, EL/EW = 1.58; apex broadly truncate, without outer angles, inner angles broadly obtuse; intervals flat; the 3rd interval with three setiferous pores, all on median portion of the interval; legs moderately developed; the 4th hind tarsomere emarginated as deep as 1/3 of the joint; all tarsal claws pectinate; prosternal process well-bordered at apex; abdominal ventrite VII in male slightly emarginated at apical margin.

Male genitalia (Fig. 3B, C): Median lobe of aedeagus stout, more or less bent near apex, apex pointed in profile, but obtuse in dorsal aspect, apical lamella longer than wide.

Remarks.

Allied to Orthogonius morvanianus sp. n. Differs from the latter by its labrum shallowly emarginated at front, the 4th hind tarsomere having a deeper emargination, and apical lamella of aedeagus blunt at apex (see below for detail).
