M a t e r i a l s t u d i e d: ♂ Holotype: SABAH, Poring H.S., X.1990, G. de Rougemont / HOLOTYPE Oedichirus viduasinae des. 2015 G. de Rougemont [ CRO] ; 2♀♀ paratypes: SABAH, Mt. Kinabalu , 1500 m, 25.IV.1987, Burckhardt – Löbl / PARATYPE Oedichirus viduasinae des. 2015 G. de Rougemont [ MHNG] ; 1♀ paratype: BORNEO SABAH Kinabalu Nat. Pk. HQ 1560-1660m 24.IV.87, A. Smetana / Oedichirus det. Lee Herman / PARATYPE Oedichirus viduasinae des. 2016 G. de Rougemont [ AMNH] .

D e s c r i p t i o n: length: 6.8 mm; length of fore-body: 3.1; length of head: 0.85; breadth of head: 1; length of antenna: 2.1; length of pronotum: 1.2; breadth of pronotum: 1; length of elytron: 0.95; breadth of elytra: 1.12. Body entirely black, palpi testaceous, the last two segments of maxillary palpi brown; antennae and legs testaceous, the knees broadly and sharply infuscate. Dorsal surfaces devoid of microsculpture. Pubescence erect, short and sparse on head and pronotum, long and denser on elytra and abdomen. Habitus: Fig. 32h.

Head moderately transverse; eyes large and very prominent; post-ocular border entire, consisting of a row of punctures above a carina which forms a salient tooth behind eye; frons with only five small punctures, disc from level of antennal tubercles to base with many randomly disposed large punctures, the interstices mostly greater than diameter of punctures. Pronotum fairly short, broader than head anteriorly; lateral margins not bordered; punctures numerous, set in foveate impressions; discal series of four punctures, the anterior three in a common groove, punctures on rest of disc disposed randomly. Micropterous, humeral angles completely obsolete; puncturation comparable to that of head but less coarse, dense near suture, sparser laterally. Puncturation of abdomen arranged in discrete transverse rows, the punctures coarse, the row of basal keels of tergites separate from first row of punctures.

Male: sternite VII unmodified; posterior margin of sternite VIII (Fig. 32s8) asymmetrically sinuate, with a pale membranous flange; aedoeagus: Fig. 32arl, the right paramere slender, extending beyond apex of median lobe; left paramere stouter and curved.

Female: sternite IX: Fig. 32vp.

O. viduasinae nov. sp, is readily distinguished from all other Bornean species because it is the only micropterous one, and the only one with abdominal punctures arranged in transverse rows. Key 2.
