Description (of type): length: 7 mm; length of fore-body: 3.2; length of head: 0.75; breadth of head: 0.92; length of antenna: 1.65; length of pronotum: 1.1; breadth of pronotum: 0.9; length of elytron: 1.32; breadth of elytra: 1.3. Head black, pronotum red, elytra black, abdominal segments III-VI red, the following black; palpi and antennae testaceous, legs testaceous, knees infuscate. Dorsal surfaces devoid of microsculpture. Pubescence pale, fairly long and dense, erect on head, pronotum and abdomen, decumbent on elytra. Habitus: Figs 14h (ex. from Laos), 14hjp (type of O. ideae).

Head very transverse; post-ocular groove well marked by series of small punctures, but carina feeble, not forming an angle behind eyes; puncturation sparse, consisting of a number of very small punctures on frons, 5-6 larger punctures on vertex, 4-5 ocular punctures, the posterior one large, and transverse series half a dozen punctures just before base, in addition to the very small punctures in post-ocular furrow. Pronotum strongly elongate, the sides convergent in straight lines from anterior angles to base; lateral margins not bordered; disc with a pair of series of five punctures each preceded by a pair of smaller punctures set more closely together than discal series, and near the anterior margin a series of six punctures disposed in an arc, two large lateral punctures, and the usual small punctures along lateral margins. Elytra elongate, ample, widest at posterior 1/3 rd, the sides rounded between well marked humeral angles and acute posterior angles, the joint posterior margin coarctate; puncturation coarse and close, the interstices in anterior ¾ almost everywhere narrower than diameter of punctures. Puncturation of abdominal tergites arranged in three discrete transverse rows and an anterior transverse row adjacent to anterior row of keels.

Male: abdominal sternite VII unmodified; sternite VIII: Fig. 14s8; aedoeagus: Figs 14arl, av.

Female: sternite IX and vulvar plate (of a specimen from Japan): 14vp.

Variability: the extent of infuscation of the knees varies; in most specimens from Japan and the Ryukyu Islands (= O. idea SHARP), the legs are uniformly testaceous; elsewhere the knees are more or less extensively infuscate. In the female from Galle, Sri Lanka, the abdominal segments III-VI are very dark, almost black. The type of O. schultheissi FAUVEL does not differ in any way from typical O. longipennis ; FAUVEL seems to have been unaware of KRAATZ’ species, for he compared O. schultheissi to his own West Palearctic species O. walkeri. In BERNHAUER & SCHUBERT’ s catalogue (1912, 40: 202) the home of O. schultheissi (Sumatra) is erroneously given as Burma, probably because Fauvel’s article is entitled "Staphylinides nouveaux de l’Inde et de la Birmanie ". The specimen from "Kombuis" is the type of O. excellens CAMERON, but does not bear a CAMERON Type label. The specimen only differs from typical O. longipennis by being generally paler: the knees are less extensively infuscate than in typical specimens, and the centre of each elytron is broadly reddish.

O. longipennis is very close to O. lewisius SHARP, from which it is most evidently distinguished by its more densely punctate and larger elytra (distinctly longer than pronotum), differences in shape of the emargination of male 8 th sternite and of the anterior process of the ventral sclerite of the aedoeagus. The ranges of the two species overlap in southern Honshu, Kyushu and the Ryukyu Islands.

O. longipennis is the commonest and by far the most widespread species of the genus (distribution map, below) with a range that covers the entire Oriental Region except, as far as we know, the Philippines. It was previously recorded from northern and southern India and Pakistan, and, as O. lewisius , from Java (RATNA et. al. 2002) Shanghai ( LI et al. 2010) and Guangxi ( WANG 1990). O. ‘ idae ’ was described from Tokunoshima Island and recorded from Honshu and Kyushu. Rather surprisingly SHARP did not consider O. longipennis when he described O. ‘idea’, and CAMERON also omitted mention of Sharp’s two species when he redescribed O. longipennis (1932) ; it is more easily understandable that later Chinese and Indonesian authors looked to the far-eastern species when they recorded O. lewisius from China and Indonesia rather to the less well known O. longipennis described from India. O. longipennis is recorded here for the first time from Nepal, Ceylon, Thailand, Laos, Vietnam, China, Taiwan, Malaysia, Singapore and Celebes.
