The genus Acanthoscurria was introduced in 1842 with the type species A. geniculata. Since then, Acanthoscurria spp. have been found in other parts of South America, well out of the rainforest, as far south as Argentina. The most recent Argentinian introduction was A. belterrensis (2014), the first, Acanthoscurria cordubensis (1894). The name cordubensis presumably comes from the city Córdoba, which lies within the range of A. cordubensis shown below (yellow markers: A. cordubensis, red markers, A. chacoana ):
The region occupied by A. cordubensis corresponds well to the Chaco, a semi-arid scrubland covering vast expanses of poorly draining floodplain in northern Argentina and adjacent countries. Rainfall east-to-west varies from 20-50 inches/year. The word ‘Chaco’ derives from the Quechua word chaqu, meaning ‘hunting land.’ Further south, Chaco merges with Pampas, an extensive grassland plain receiving half as much rain, 10-20 inches/year (roughly the same as southern California).
