D e s c r i p t i o n: length:
6 mm
; length of fore-body: 2.5; length of head: 0.64; breadth of head: 0.82; length of antenna: 1.8; length of pronotum: 1; breadth of pronotum: 0.9; length of elytron: 0.95; breadth of elytra: 0.87. Body piceous, palpi, antennae and legs uniformly testaceous. Fore-body devoid of microsculpture, micro-reticulation of abdominal tergites III-VII scarcely distinguishable, distinct on tergites VIII-IX. Pubescence of mixed lengths, erect. Habitus: Fig. 47h.
Head strongly transverse, eyes prominent but not very large; post-ocular carina salient, ending anteriad in a dentiform angle well removed from posterior margin of eye, groove above carina scarcely distinguishable; puncturation sparse, consisting of a few irregularly scattered small frontal punctures, a pair of very large closely-set umbilicate punctures on vertex, about eight scattered punctures on each postero-lateral area, and about five small punctures on each side on post-ocular border. Pronotum short, lateral margins entirely bordered; disc with an irregular but discernible pair of discal series of six punctures each preceded by a cluster of about ten punctures, a few small scattered lateral punctures in anterior half, a posterior lateral series of three large punctures, and 5-6 small punctures along lateral margins. Micropterous, elytra measured along suture shorter than pronotum, humeral angles much reduced but not completely obsolete; puncturation coarse and dense, especially near suture. Punctures of abdominal tergites apparently random on tergites III and IV, clearly arranged in discrete transverse rows on following tergites.
Male: sternite VII: unmodified; aedoeagus: Fig. 47arl.
Female: sternite IX (of ex. From
Kanchanaburi prov.
): Fig. 47vp.
This species is similar to
O. uncifer
nov.sp.
from which it may be distinguished by the puncturation of the abdominal tergites, as described in Key 3.
