Antennuloniscus Menzies, 1962 View in CoL
Type species: Antennuloniscus dimeroceras (Barnard, 1920) .
Diagnosis. Haploniscidae with third peduncle article of antenna 2 elongate and grooved to accommodate the distal articles when the antenna is folded caudally. Peduncle article 4 short, 5 and 6 fused; whip-like flagellum small, slender and subterminal.
Remarks. This genus is similar to Haploniscus but undoubtedly different as discussed by Menzies and Schultz (1968) in describing Antennuloniscus subellipticus from the south Atlantic off Cape Horn, and A. quadratus from the Indian ocean off Madagascar. The type species A. dimeroceras Barnard, 1920 was collected from both the north and south Atlantic. Two other south Atlantic deep-sea species are A. ornatus Menzies, 1962 off Cape Horn and South Georgia and A. armatus Menzies 1962 , from off South Africa. Chardy (1974) described yet another species, A. dilatatus , from the north-east Atlantic off the Azores. The addition of two new species, A. menziesi n. sp. and A. lincolni n. sp. from the north-west Atlantic, in this study, brings the total known species of this genus to nine. This genus was not reported by Menzies and George (1972) while studying haploniscid isopods in the south-east Pacific, and it was not found in the north-east Pacific, in the study of haploniscids by Birstein (1963).
