The single type specimen, a worker, was collected from from rainforest leaf mould berlesate.
Mezger & Pfeiffer (2010) - Separated from all other species by combination of four distinct setae on posterior section of head. Medium pair of these setae close together at midline of head, other pair wider sepa-rated and closer to occiput. Each of these setae 0.04 mm long. Postpetiole with one seta at each side. Eye with 20 ommatidia. Ground pilosity less dense with mean distance of squamiform hairs 18 μm and diameter of foveolae around 28 μm, i.e., distances between squamiform hairs large and resembling Eurhopalothrix elke, but diameter of foveolae more similar to Eurhopalothrix platisquama. Scape with two rows of setae, one outer row with seven setae and one inner row with nine setae (Fig. 16). Mandible 1.1 times as broad as long. Due to extensive gold-coverage for former SEM studies no information on number of teeth available.

All Class A attributes present, with those of Class B, unless otherwise indicated. Dimensions (mm): HL 0.71; HW 0.79; CI 112; ML 0.19; MI 27; SL 0.41; SI 52; PW 0.48; WL 0.83. Eyes large, as in Eurhopalothrix platisquama. Occipital border almost straight, transverse (its outline at most minutely curved or sinuous). Posterior occipital angles obtusely rounded, forming angles of about 130°. Mesosomal profile not a continuous curve, its outline interrupted at the promesonotal/propodeal junction by a minute indentation; the mesometanotal suture not incised dorsally to break the surrounding sculpture. Petiolar node in dorsal view essentially square, its length and breadth sub equal (bias transverse).
Frons and most dorsal body surfaces with ground pilosity of dense, flattened, appressed, squamous, shining silvery hairs, which are less strongly developed than in E. platisquama and Eurhopalothrix dubia, so as barely to overlap the punctures in which they lie, which remain more clearly visible than in the other species mentioned. Four relatively short specialised hairs on posterior occipital border, the median pair adjacent, the laterals each about midway between them and the posterior occipital angles; the hairs clavate, barely expanded, though somewhat thick and columnar. Erect hairs lacking elsewhere on promesonotum, petiolar node and dorsum of first gastral tergite; one pair (posterolateral) on postpetiole.
Malaysia: Sarawak: First Division: Kampong Segu, 20 miles S.W. of Kuching (01°33'N.,110°20'E.). Known only from the unique worker holotype, from a rainforest leaf mould berlesate (RWT acc 68 .289, 4.vi.1968). In Australian National Insect Collection (type No. 7783); gold-palladium coated for SEM study.
