Strumigenys belua

The type material was collected in subtropical rainforest. The specimen was apparently taken from a litter sample ("forest, log & leaf litter").

Identification
Bolton (2000) - A member of the smythiesii complex in the Strumigenys godeffroyi-group. Immediately identified among the members of the smythiesii-complex by its dorsally smooth and dorsolaterally laminate propodeum, longitudinally carinate mesonotum and small eyes. See also notes under Strumigenys friedae.

Worker
Holotype. TL 2.3, HL 0.57, HW 0.39, CI 68, ML 0.24, MI 42, SL 0.35, SI 90, PW 0.25, AL 0.62. With characters of smythiesii-complex. Apicoscrobal hair flagellate, long and straggly. Cephalic dorsum sharply reticulate-punctate, the ground pilosity dense and narrowly spatulate. A single pair of erect hairs present on cephalic dorsum, close to midline near occipital margin. Eye small, composed of 3-4 larger ommatidia and about 4 smaller ommatidia around the ventral periphery; maximum diameter of eye less than maximum width of scape. Scrobe broad between dorsal and ventral margins but quite shallow. Pronotal humeral hair long, flagellate. Pronotum without other erect hairs; a single pair present on mesonotum. Promesonotal dorsum reticulate-punctate but propodeal dorsum almost smooth, with only faint superficial traces of sculpture. Mesonotum with a median longitudinal carina, weakest anteriorly, most strongly developed close to propodeum. Propodeum with a vertical low cuticular lamella on each dorsolateral margin, that extends the length of the segment and terminates on the dorsal base of the propodeal tooth. Propodeal declivity with a broad lamella, its posterior (free) margin concave at level of spiracle but convex below this. Entire side of alitrunk, including side of pronotum, mostly smooth; any sculpture present is restricted to the extreme periphery of the sclerites. Dorsal surface of petiole in profile with a cuticular crest that extends from midlength of peduncle to anterodorsal angle of node. Dorsum of petiole node with faint superficial sculpture only, almost smooth; disc of postpetiole glassy smooth. Hairs on first gastral tergite long and fine, filiform to subflagellate or narrowly looped apically.
