Ornebius pullus Ingrisch, 2006: 157

Material examined. Singapore, 2 males, Bukit Timah Nature Reserve, along BTNR main road, secondary forest, coll. M. K. Tan, H. Yeo, Y. F. Chung & T. M. Leong, 23 October 2010, 9 January 2013; 1 male, MacRitchie Catchment Area, along MacRitchie Nature Trail, secondary forest, coll. M. K. Tan, 2 February 2011; 1 male, Hindhede Nature Park, secondary forest, coll. M. K. Tan & J. J. Y. Chan, 29 January 2012 (all ZRC).

Discussion. The specimens examined from Singapore are very similar to this species, first described from Brunei, Northern Borneo (Ingrisch, 2006). They show an overall similarity with regard to general habitus, colouration, abdominal apex and phallic complex although it appears that there are some minute differences in the abdominal apex, which could be due to different conservation, and phallic complex: The internal sclerites of the type from Brunei and the specimens from Singapore look very similar but the widened apical part appears to be a little longer in the latter. The medial valves that form a "tube" around these sclerites look identical between the specimens. The lateral valves look different, but they are not sclerotised and thus due to distortion during conservation. Specimens from Singapore may represent the first record of this species outside Borneo and in Singapore. This also indicates the first occurrence of Ornebius with completely membranous lateral valves outside Northern Borneo.

Ornebius rufonigrus Ingrisch, 2006: 158

Material examined. Singapore, 1 male, Pasir Panjang, cliff forest, on foliage, coll. D. H. Murphy, 3 March 1974; 1 male, Changi mangrove, coll. D. H. Murphy, 28 September 1974; 2 males, 1 female, Pulau Ubin, along Sensory Trail, secondary forest or mangrove, on foliage, coll. M. K. Tan, 29 January 2010, 21 February 2010, 4 August 2012; 1 male, along Neo Tiew Lane 2, secondary forest, on foliage, coll. M. K. Tan & R. W. J. Ngiam, 28 August 2010 (all ZRC).

Discussion. This species was first described from Southern Thailand (Ingrisch, 1987). Materials examined represent the first confirmed record of this species outside Thailand and in Singapore although it was previously recorded tentatively as Ornebius sp. in Tan (2010).
