Strumigenys manga Fisher sp. n.

HOLOTYPE WORKER. TL 2.4, HL 0.56, HW 0.49, CI 88, ML 0.22, MI 40, SL 0.26, SI 53, PW 0.29, AL 0.63. Characters of abdera-comp \ e \. Left mandible with a distal preapical denticle and a proximal preapical tooth; right mandible with a small distal preapical tooth and a proximal preapical tooth. Cephalic dorsum posterior of clypeal margin and upper scrobe margin with clavate to spoon-shaped hairs that are distinctly narrower than the hairs on leading edge of scape. Cephalic dorsum with a transverse row of 4 erect, short clavate hairs close to the occipital margin. Pronotal humeral hair present, stiffly projecting; mesonotum with a short clavate hair on lateral anterior margin. In profile, outline of alitrunk convex in anterior half, more or less flat in posterior half; anterior mesonotal dorsum steeply descending to its posterior half. Propodeal dorsum more or less flat and meeting the declivity in rounded angle without a noticeable cuticular tooth. In profile, spongiform lamella continuous down propodeal declivity and marginate medially, forming a triangular tooth at apex of declivity. Ventral spongiform tissue and lateral lobes well developed and conspicuous on petiole and postpetiole; petiolar lamella notched medially. Base of first gastral tergite with basal costulae arising on each side of a central clear area. Dorsal surfaces of petiole, postpetiole, and gaster with clavate standing hairs. Color brown.

PARATYPE WORKERS. TL 2.5, HL 0.56 - 0.57, HW 0.51 - 0.52, CI 90 - 91, ML 0.22, MI 39, SL 0.30 SI 59 - 60, PW 0.30 - 0.31, AL 0.65 - 0.67 (2 measured). As holotype.

Holotype worker, Madagascar: Foret d'Ankazomivady, 29 km. SSW Ambositra, 1700 m., 20 ° 46 ' 36 " S, 47 ° 9 ' 54 " E, 8. i. 1998, disturbed forest, nest 3 cm. below leaf-litter covered soil surface found by digging SAM # 011226 (H. R. Robertson) (SAM). Paratypes. 2 worker and 1 queen (dealate) with same data as holotype (BMNH).

S. manga is separated from the other species in the arnoldi-group with 6 antennal segments by the presence of an erect pronotal humeral hair, presence of hairs on anterolateral margin of mesonotum, and the shape of the alitrunk in profile which is convex anteriorly and more or less flat posteriorly.
