Description
Worker
General features as illustrated. All Class A attributes present, with those of Class B, unless otherwise indicated. Dimensions (mm): HL 0.50; HW 0.53; CI 106; ML 0.12; MI 24; SL 0•29; SI 55; PW 0.29; WL 0.56. Eyes either lacking or imperceptibly minute. Face of clypeus between frontal lobes divided by an almost vestigial low, transverse welt.
Frons spanned by a slightly arched, shallowly depressed groove emanating on each side at about the normal position of the eye; bordered anteriorly by a conspicuous transverse welt. Occipital border broadly and distinctly emarginate (its outline comparatively somewhat 'V' shaped; not an even arc); occipital angles approximately right angular. Mesosomal profile almost a continuous curve, but interrupted at the promesonotal/propodeal junction by a minute, very feebly indented notch. Metanotal groove weakly incised dorsally as a distinct trench which more-or-less severs the surrounding sculpture. Petiolar node in dorsal view distinctly longer than wide. Specialised enlarged hairs lacking on promesonotum, petiole and postpetiole, represented only be one pair on the frons (one hair has been lost from the holotype); the remaining hair clavate, expanded to about t its maximum height, well differentiated from the minute ground pilosity. Several such hairs at least are probably normally present on the dorsal surface of first gastral tergite, where the holotype has a single, unpaired, club-shaped mediolateral hair. Ground pilosity minute, scattered, moderately prominent on gastral dorsum.
Type Material
Malaysia: Sabab: Lungmanis, mile 45 (Labuk Rd, ex Sandakan) (05°52'N., 118°04'E.). Holotype. Worker, collected from berlesate, rainforest leaf mould (RWT ace 68.502, 12-13.vi.1968). In Australian National Insect Collection (type No. 7775); the specimen gold-palladium coated for SEM study.
Etymology
Named for Professor W. L. Brown Jr, of Cornell University.
