Identification

Bolton (2000) - A member of the mayri complex in the Strumigenys mayri-group. See notes under Strumigenys akhtoi for related Malesian species. S. missina is closely related to the mainly Australian Strumigenys ferocior, but that species has longer scapes and a more sharply defined and deeply incised preocular notch. Based on material currently available it does not appear to be con specific with missina but if intermediates are found in western New Guinea the situation will need review.

Description

Worker

Holotype. TL 2.4, HL 0.67, HW 0.50, CI 75, ML 0.33, MI 49, SL 0.42, SI 84, PW 0.28, AL 0.65. Characters of the mayri-complex. Preapical tooth spiniform, its length about equal to maximum width of mandible. Cephalic dorsum with 4-6 erect simple hairs along the occipital margin and a similar pair at level of highest point of vertex. With head in full-face view the upper scrobe margin above the eye sufficiently expanded to obscure the junction of the eye with the head capsule, but outer curvature of eye visible. Preocular notch present but not as broad and deep as elsewhere in the complex; ventral surface of head with a shallow preocular transverse impression. Pronotal humeral hair simple, pronotum otherwise without erect hairs; mesonotum with one pair of erect simple hairs. Dorsal alitrunk evenly reticulate-punctate. Dorsal surfaces of waist segments and gastral tergites with simple stiff hairs. Katepisternum with a smooth patch on lower half; metapleuron and side of propodeum reticulate-punctate. Propodeum armed with a pair of short spines, length of spine slightly greater than distance sFeparating their bases but less than dorsal width of petiole node. Dorsal (outer) surface of hind basitarsus without long fine erect hairs. Petiole in profile with anterior face of node not markedly less than length of dorsum, in dorsal view petiole node slightly broader than long. Disc of postpetiole finely and densely reticulate-punctate.

Paratypes. TL 2.4-2.5, HL 0.67-0.69, HW 0.49-0.50, CI 72-75, ML 0.32-0.34, MI 47-49, SL 0.40-0.44, SI 84-88, PW 0.28-0.32, AL 0.64-0.70 (6 measured).
