Strumigenys domitia

Known from a holotype worker found in montane primary forest litter.

Identification
Bolton (2000) - A member of the Strumigenys sisyrata-group. A very distinctive species that should not be confused with any other from the region. Its only close relative appears to be Strumigenys sisyrata but the two are easily differentiated because of the enormous development of spongiform tissue in that species, absent from domitia.

Distribution based on Regional Taxon Lists
Indo-Australian Region: Indonesia, New Guinea.

Worker
Holotype. TL 4.2, HL 1.10, HW 0.90, CI 82, ML 0.59, MI 54, SL 0.78, SI 87, PW 0.54, AL 1.16. Dorsolateral margin of head with 4 laterally projecting fine sub flagellate hairs: one just behind level of eye, one in apicoscrobal position, one on side of occipital lobe, one at occipital angle. Ventrolateral margin of head with a small preocular impression. Cephalic dorsum finely and predominantly longitudinally rugulose; a pair of short erect hairs present just posterior to level of eye, a longer pair posterior to this and a row of 6-8 erect fine hairs along occipital margin. Pronotum marginate dorsolaterally; the dorsum, and to a lesser extent the side, with a dense pelt of closely applied long-spatulate ground-pilosity. On posterior mesonotum and propodeum ground pilosity is longer, more elevated and strongly curved. Pronotal humeral hair long and flagellate; pronotal dorsum with a pair of erect flagellate hairs and mesonotum with 3 pairs. Dorsal alitrunk irregularly rugulose. Dorsolateral margin of alitrunk, from humeral angle to propodeal spine, made very irregular by numerous small blunt cuticular prominences and tubercles. Side of pronotum with numerous small cuticular pustules or tubercles. Pleurae and side of propodeum irregularly rugulose except for lower katepisternum which is smooth. Propodeum with a pair of long slender spines, the lamella on the declivity narrow and feebly developed, inconspicuous. Dorsal and ventral surfaces of hind femur with erect fine long hairs; hind basitarsus with 3 flagellate hairs. Lateral spongiform lobe of petiole large, in profile length of lobe greater than length of exposed cuticle of node. Disc of postpetiole densely longitudinally costulate. First gastral tergite with long flagellate hairs. Basigastral costulae short but extending onto tergite proper, not restricted to limbus.

Type Material
