Abstract

Five halacarid species are reported from the Brazilian coast for the first time. Scaptognathides delicatulus, formerly known only from its type locality in Kuwait; Scaptognathus gibbosus, known from Galapagos and Somalia; and Scaptognathus insularis known from northeastern Australia, have their distributions extended. Along with these new records, Halacaroides antoniazziae sp. nov. and Acarochelopodia caissara sp. nov. are described. Halacaroides antoniazziae sp. nov. differs from its congeners by the presence of three subgenital setae in males and none in females, 41–44 perigenital setae and two posterior external genital acetabula in males. Acarochelopodia caissara sp. nov. has a rounded anterior epimeral plate margin, the posterior epimeral plates are partially divided into two halves but anteriorly joined by a narrow band, the dorsal setae on tarsus I are grouped 1:2, and the anterior and posterior dorsal plates have a length: width ratio of 1.61–1.77 and 1.60–1.70, respectively.
