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 balnearius des. 2015 G. de Rougemont [ CRO] ; 1♂ & 1♀ paratypes: [Ibid.] / PARATYPE Oedichirus balnearius des. 2015 G. de Rougemont [ CRO] .

A d d i t i o n a l m a t e r i a l: 1♀: Borneo MALAYSIA: Sabah: Mt. Kinabalu Park, Park Headquarter 1300- /1600 6º01’N 116º32’E (am Licht), D. Bartsch & C. Hauser leg. / Oedichirus balnearius det. 2017 G. de Rougemont [SMNS].

D e s c r i p t i o n: length: 9.5 mm; length of fore-body: 4.6; length of head: 1; breadth of head: 1.32; length of antenna: 3.3; length of pronotum: 1.5; breadth of pronotum: 1.18; length of elytron: 2.05; breadth of elytra: 1.55. Body entirely black; legs testaceous, the apices of femora narrowly but sharply infuscate; palpi and antennae testaceous. Forebody devoid of microsculpture, abdomen entirely microsculptate. Pubescence pale, moderately long, directed forward on head, erect on pronotum, decumbent on elytra and abdomen. Habitus: Fig. 30h.

Head transverse; eyes large and protruberent; anterior surface of head a little uneven, wrinkled; disc with sparse, randomly scattered umbilicate punctures and a row of smaller punctures along posterior margin; temples very short; post-ocular border in the form of a groove bordered posteriorly by a ridge forming a salient angle behind eye. Antennae long, the second and third antennomeres sub-equal, IV-VII very long, VIII-X progressively shorter. Pronotum very elongate, the sides strongly retracted from anterior to posterior angles; lateral line not bordered; puncturation coarse, dense, without evident discal series. Elytra with prominent humeral angles and rounded sides, the puncturation coarse and dense, not serially aligned. Abdomen entirely finely microsculptate, with coarse, dense, randomly disposed punctures.

Male: abdominal sternite VII unmodified; sternite VIII: Fig. 30s8, with a deep apical emargination the fundus of which is bordered by a bead, the area in front of emargination impunctate and more densely microsculptate than lateral areas; aedoeagus: Fig. 30arl, slender right paramere much longer than left.

Female: sternite IX: Fig. 30vp.

Of the known Bornean species, O. balnearius sp. nov. most closely resembles O. pendleburyi CAMERON, from which it differs most obviously by its greater size, infuscate apices of femora, and and the sexual characters.
