Description
Worker
Holotype. TL 5.70, HL 1.53, HW 1.65, FC 1.28, CS 1.59, SL 0.75, SI1 45, SI2 47, PML 1.02, PW 1.30, PMD 1.38, PMI2 106, ML 1.30, PSL 0.58, PTLL 0.40, PTLH 0.58, PTDW 0.52, PPLL 0.40, PPLH 0.54, PPI 74, PPDW 0.52, PT/PP 100.
Mandible with three teeth. Clypeal projection very similar to that of preceding species, with lateral teeth less produced. Head moderately wider than long (CI 108), preoccipital margin shallowly though still markedly concave. Frontal carinae more evenly and less sinuately narrowed towards clypeus (FI 129). Antennal scrobe not surpassing middle of lateral sides of head as far as in convexius, anteriorly glossy, distinctly transversely carinulate at rear, posteriorly indistinctly demarcated from remainder of head. Genae and ventrolateral sides of head rugose, preoccipital lobes reticulate. Eyes relatively larger (EL 0.29, REL 0.19, with 17 ommatidia in the longest row), situated in front of middle of lateral sides of head, dorsal ocular margin not reaching ventral scrobal margin. Head in posterior half distinctly reticulate, between ridges of rugo-reticulation with faint microsculpture.
Promesonotal shield wider than long (PMI 127) with regular reticulation, lateral sides only very narrowly translucently margined, projections less developed as in preceding species. Propodeal declivity overhung by posterior mesonotal margin, only partly visible from above. Propodeal spines long in relation to body size (PSL 0.58) situated above middle of length of declivity, acute and moderately diverging when seen from above.
Petiole in lateral view more or less triangular, higher than long (PTI 70), with anterior face straight, meeting convex to sinuate posterior face in a crest. Postpetiole nodiform with a small anterio-basal tooth.
First gastral tergite entirely microreticulate, basally with additional carinulae. Pilosity similar to that of preceding species.
Most workers are slightly bicolored with the gaster and appendages usually ferrugineous and the remainder of body brown.
(n = 6). TL 5.05-5.70, HL 1.35-1.53, HW 1.48-1.65, FC 1.13-1.28, FI 125-131, CI 107-110, CS 1.41-1.6, SL 0.74-0.78, SI1 45-50, SI2 47-52, PML 1.0-1.08, PW 1.20-1.33, PMI 119-127, PMD 1.29-1.45, PMI2 106-109, ML 1.20-1.35, PSL 0.54-0.63, PTLL 0.35-0.40, PTLH 0.51-0.65, PTI 62-71, PTDW 0.48-0.55, PPLL 0.33-0.40, PPLH 0.50-0.56, PPI 65-76, PPDW 0.48-0.55, PT/PP 100-105, EL 0.25-0.29, REL 0.18-0.19, with 17-18 ommatidia in the longest row.
Type Material
Holotype worker, Northern Territory: 'NT Barrow Creek 5 km NE 21.29S 133.35E 10/10/81 135b D. Davidson / S. Morton' (Australian National Insect Collection). Paratypes. 5 workers, same data as holotype; 12 workers with same locality data but '135a' and '135c' (ANIC, Naturhistorisches Museum Wien, Vienna).
Etymology
An anagram based on the name of my son Sebastian, who occasionally joins me on entomological trips and does some real good collecting—in particular crickets and flies.
