Nomenclature

 *  seguensis. Eurhopalothrix seguensis Taylor, 1990b: 421, figs. 34, 41-43, 55 (w.) BORNEO.

Worker
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.

Type Material
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 (type No. 7783); gold-palladium coated for SEM study.

Etymology
Named for the type locality.
