D e s c r i p t i o n: length: 6-6.5 mm; length of fore-body: 2.8; length of head: 0.7; breadth of head: 0.85; length of antenna: 2; length of pronotum: 1.05; breadth of pronotum: 1; length of elytron: 0.77; breadth of elytra: 1. Body black, all appendages testaceous. Dorsal surfaces glossy, devoid of microsculpture except on row of keels and grooves on anterior margins of abdominal tergites. Pubescence of fore-body sparse, short, erect, that of abdomen longer. Habitus: Fig. 1h.

Head strongly transverse; post-ocular carina fine, not forming a sharp angle anteriad; puncturation composed of irregularly scattered umbilicate punctures of varying sizes, the interstices everywhere greater than diameter of punctures. Pronotum cordiform, anteriorly nearly as broad as its length; lateral margins entirely bordered; puncturation comparable to that of head, composed of irregularly scattered larger and smaller punctures, not forming discernible series, the interstices almost everywhere much greater than diameter of punctures. Micropterous, elytra short, broadest at middle, the joint posterior margin almost straight; punctures comparable in size to those of head and pronotum, dense on either side of suture, sparser laterally. Abdominal tergites with rather long keels and grooves along anterior margins; punctures disposed randomly, not forming discernible rows, of unequal sizes, moderately sparse on anterior tergites, becoming progressively sparser posteriad.

Male: abdominal sternites unmodified; aedoeagus: Figs 1arl, 1av.

Female: sternite IX: Fig. 1vp

This is the first species of Oedichirus recorded from the Aru Islands.
