Wingstrandarctus corallinus Kristensen, 1984

Material examined: 28 specimens, 5 from site 1 (1 female, 124 µm long, and 4 specimens of unknown gender, 104–141 µm long), 13 from site 2 (9 females, 132–168 µm long; 2 males, 86 and 99 µm long; and 2 specimens of unknown gender, 144 and 167 µm long), 5 from site 3 (3 females, 116–140 µm long; 2 specimens of unknown gender, 102 and 134 µm long); 4 females, 133–164 µm long, from site 9; and 1 specimen of unknown gender, 163 µm long, from site 11.

Remarks: The genus Wingstrandarctus contains five known species ( Jørgensen et al. 2014) that have alae without caesti. Unlike W. unsculptus Jørgensen, Boesgaard, Møebjerg & Kristensen, 2014 , the Bahamian specimens do have a sculptured cuticle. Unlike W. stinae Jørgensen, Boesgaard, Møbjerg & Kristensen, 2014 , they do not have constricted primary clavae, and the shape of the alae differs as well. The caudal alae of our specimens are much smaller than those of W. intermedius Renaud-Mornant, 1967 , and the internal claws have accessory points unlike W. crypticus Renaud-Mornant, 1989 . The Bahamian specimens do match W. corallinus in all traits.

Wingstrandarctus corallinus is an intertidal and shallow subtidal species. The type locality is Australia, but it has been recorded in the Western Atlantic in Florida, USA (Kristensen 1984) and many other areas (Kaczmarek et al. 2015, Bartels et al. 2015b).
