Wilson Lourenco has described a new species of Hadrurochactas (Chactidae) from Brazil:
Hadrurochactas araripe Lourenco, 2010
The paper also discuss the disrupted distribution pattern of the genus Hadurochactas.
Abstract:
A new species, Hadrurochactas araripe sp. n. (Chactidae) is described from ‘Chapada do Araripe’, a ‘Brejo type’ formation located in the State of Pernambuco, Brazil. The description of the new species confirms a disrupted pattern of distribution presented by the genus Hadrurochactas. This includes species present both in Guiano-Amazon forests and forest islands within the ‘Caatingas’. These are xerophytic formations in northeastern Brazil. This new species brings further evidence of a past connection between the Amazonian and Atlantic forests, as already suggested by palaeobotanists.
