Metapone jacobsoni

Distribution based on Regional Taxon Lists
Indo-Australian Region: Indonesia. Oriental Region: India, Nicobar Island.

Biology
Taylor and Alpert (2016) - M. jacobsoni seems more likely to be introduced than native on Great Nicobar Island, and Sumatra is the most likely ancestral source for the island population. The two lands are separated by less than 200km of open ocean, across which there must have been much past human passage in small boats, perhaps often carrying unmilled (fire)wood, possibly facilitating introduction.

Taylor and Alpert (2016) - (holotype, paratype): TL: 8.5, 8.75; HL: 1.48, 1.44; HW (across eyes): 1.00, 1.04; Maximum eye length: 0.42, 0.38; CI: 68, 72; MSL: 2.26, 2.30; PMW: 0.92, 0.94; PDW: 0.70, 0.72; PetL: 0.56, 0.60; PetW: 0.44, 0.46; PetH: 0.72, - ; PpetL: 0.44, - ; PpetW: 0.58, 0.58.

General features as in original description (Crawley, 1924), the key to Asian Metapone species and the relevant figures. Posterior face of subpetiolar process in oblique view relatively large, triangular; subpetiolar angle in side view approximately a right angle, not spinose; subpetiolar lamella opaque, approximately equilaterally triangular (note that the petiole could not be viewed unobstructed in true profile for illustration; its somewhat obscure outline is highlighted in figure). Other features are adequately illustrated.
