GENUS CIRCONISCUS PEARSE, 1917 View in CoL
Type species: Circoniscus gaigei Pearse, 1917 , by monotypy.
Diagnosis
See Souza & Lemos de Castro (1991) and Schmidt (2007).
Remarks
Schmidt (2007) revised the Neotropical Scleropactidae and redefined Circoniscus , considering the schisma on pereonite 1 as the autapomorphic character of the genus, as assumed by Souza & Lemos de Castro (1991). The genus Amazoniscus was included in the same clade and considered as the sister group of Circoniscus . Recently, Campos-Filho & Araujo (2011) described two cavernicolous species of Circoniscus from Pará, Brazil, and recorded the presence of a schisma in young individuals of C. buckupi , but lacking in adults, interpreted as a secondary loss. At present, Circoniscus includes seven species from French Guiana, Guyana, Brazil, Peru, and Paraguay ( Schmidt, 2007).
