On a record of Dardanus venosus (H. Milne Edwards) (Crustacea, Anomura) from the São Paulo State, Brazil

Abstract

The present work is the first report of Dardanus venosus (H. Milne Edwards, 1848) in São Paulo State and extends the range of this species in the western Atlantic farther to the south in the Brazilian region. A total of twenty two males (mean shield length: 7.56 ± 1.62 mm, 4.7 to 10.9 mm), and fifteen females (7.25 ± 2.53 mm, 4.3 to 14.5 mm) were collected in 1987, 1998, 1999 and 2000 by scuba diving from three areas of Anchieta Island (23º33'S, 45º05'W) in the Ubatuba region, and south of São Sebastião Island (23º57.8'S, 45º16'W), northern coast of São Paulo State. No ovigerous females were captured during the study period. Shells of eleven gastropod species were occupied by D. venosus: Astraea latispina (Philippi, 1844), A. olfersii (Philippi, 1846), A. phoebia Roding 1798, Calliostoma bullisi Clench & Turner 1960, Chicoreus tenuivaricosus (Dautzenberg, 1927), Cymatium parthenopeum (von Salis, 1793), Olivancillaria urceus (Röding, 1798), Phalium granulation (Born, 1778), Stramonita haemastoma (Linnaeus, 1767), Strombus pugilis Linnaeus, 1758 and Zidona dufresnei (Donovan, 1823).
