Material examined. Mariana Islands, Guam: reef talus, east Asana Bay, 90 m off Gold Dome, coarse foram and Halimeda rich sand, coll. G. Paulay and B. D. Smith, 14 Jul 1997: 1 male, 5.0 mm cl, 1 female, 4.0 mm cl ( FLMNH UF 324).

Distribution. Japan, Taiwan, Philippines, Vietnam Australia (Western Australia, Queensland and New South Wales), New Caledonia , Mariana Islands ( Guam), Marshall Islands, Tahiti, in 6.1–45.5 m depth ( Boyko 2002, Osawa et al. 2010, herein).

Remarks. These specimens are the first records of Paralbunea dayriti from Guam. The record by Garth et al. (1987) from Enewetak Atoll cited above is based on the same material cited by Boyko (2002). The species has a very wide range across the western Pacific. The validity of the subfamilial placement of Paralbunea is unclear. Boyko (2002) considered it as basal in the Albuneinae , while the morphological analysis of Boyko & Harvey (2009) placed as basal in the Lepidopinae . Further study, likely using molecular analysis, is required to resolve this uncertainty.
