Fischer and Fisher (2013) - Pheidole teneriffana (=P. indica) is an invasive species with collection records scattered over several continents and islands across the globe. Described from the Canary Islands and found widely distributed throughout the greater Mediterranean region, its native range and origin are unknown (Wilson 2003, Wetterer 2011). Probably introduced to the Malagasy region, it was described from Madagascar as P. voeltzkowii, only one year after the publication of the senior synonym. Morphologically, P. teneriffana can be grouped together with, and is possibly related to, Pheidole fervens, Pheidole oceanica and Pheidole sinaitica. In the New World, Pheidole teneriffana has been introduced to California (Martinez 1992, Snelling 1992), Cuba, Peru (Wilson 2003), and the West Indian islands (Wetterer 2011). It seems to be common in dry habitats (Wetterer 2011), especially along coasts and in urban areas (Collingwood et al. 1997, Gómez & Espalader 2006), and has been described as aggressive toward other ant species, locally abundant, and spreading in urban areas (Collingwood 1985, Gómez & Espalader 2006). In the Malagasy region P. teneriffana was collected on the Comoros, Mauritius, the Seychelles, and from coastal towns in Madagascar, usually from under stones, ground nests, or foraging on the ground or lower vegetation in urban or garden habitats at elevations between 2 and 296 m, on Mayotte in native littoral and secondary forest (7 m elevation). Recently in Saudi Arabia it was collected from soil, under stones, and foraging on the ground on a few farms at elevations between 570 and 1620 m.

Wilson (2003) - Evidently a native of North Africa and possibly also the Canary Islands. It has turned up in disturbed habitats in Cuba, Peru, and California, but as of this writing is evidently still sporadic and local. In 1989 Martinez (1992) found a population occupying about two hectares of Admiral Kidd Park, evidently consisting of a single continuous, polydomous colony. The separate nests contained large numbers of workers and multiple inseminated queens, as many as 23 in one instance. Nest sites included lawns and open ground, where nest entrances were surmounted by mounds of excavated soil; crevices of sidewalks and curbs; and the bases of trees. New nest sites were occupied by budding from occupied sites. The workers were aggressive toward other ant species; they preyed on insects and harvested seeds. By 1998, according to Gulmahamad and Martinez (1999), the population was extinct. It had been weakened by attempts to exterminate it and changes in the nest habitat, and given the coup de grâce by encroaching Argentine ants (Linepithema humile).
Heterick (2009) - WA Australia: Currently only confirmed for the Fremantle area, but ants of similar appearance have been seen in Claremont (a Perth suburb) and the wheatbelt town of York. Unlike the case with most nests of Pheidole megacephala, this species has diurnally active workers. Pheidole indica had not previously been reported from Australia.
Espadaler (2007) - Canary Islands: A nest with winged males was detected on cracks in the pavement. Ants rushed out after a small air blow with the aspirator.
