Pyramica symmetrix Bolton sp. n.

HOLOTYPE WORKER. TL 1.9, HL 0.50, HW 0.38, CI 76, ML 0.09, MI 18, SL 0.24, SI 63, PW 0.22, AL 0.52. Closely related to fautrix and mostly matching the description of that species, but differing as follows.

P. symmetrix : Spoon-shaped hairs on vertex clear, almost translucent, producing coloured reflections with correct angle of illumination. Lamella on propodeal declivity engages basal half or slightly less of tooth; margin of lamella narrowly convex at its midheight. Ventral spongiform curtain of petiole continuous from base to apex of segment.

P. fautrix : Spoon-shaped hairs on vertex dull, subopaque, not producing coloured reflections. Lamella on propodeal declivity engages tooth for most of its length, only tip of tooth free; margin of lamella broadly convex at its midheight. Ventral spongiform curtain of petiole absent beneath peduncle, present below node.

Holotype worker, Madagascar: Pref. Tsiroanomandidy, Bongolava, 6 - ll. xii. 1974, forest humus and litter (A. Peyrieras) (MCZ).

NON-PARATYPIC MATERIAL EXAMINED. Madagascar: no locality data (A. Peyrieras); Prov. Toliara, Forel de Petriky, 12.5 km. W 272 ° Tolagnaro (B. L. Fisher); Toliara, S. F. Mandena 8.4 km. NNE 30 ° Tolagnaro (B. L. Fisher).
