Remarks. As has been suggested by several authors, Homola orientalis is probably a species complex rather than a single widespread species that occurs across the Indian Ocean and Indo-West Pacific ( Guinot & Richer de Forges 1995; Richer de Forges & Ng 2007, 2008). Guinot & Richer de Forges (1981, 1995) and Richer de Forges & Ng (2008) discussed this matter at length, noting that two “forms” could be discerned, one from the western Pacific and another from the Indian Ocean. The small morphological differences, however, are not constant and more taxonomic work will need to be done.

Some of the present specimens were collected still holding on to various kinds of sponges ( Fig. 1 View FIGURE 1 C–E). Guinot et al. (1995) and Minemizu (2000) have already recorded H. orientalis carrying sponges, alcyonacean corals and even plant debris, and this seems to be the typical behavior for this species (see also Guinot & Wicksten 2015).

Distribution. Homola orientalis , as currently understood, is a very widespread species. It has been reported from throughout the Indo-Pacific, including Japan, Taiwan, Australia, and the Indian Ocean, from 38–700 m ( Davie & Short 1989; Guinot & Richer de Forges 1995; Richer de Forges & Ng 2007; Poore 2004; Poore et al. 2008; Ahyong et al. 2009). In Hawai‘i, the species has been reported from O‘ahu by Clarke (1972, as Thelxiope orientalis ), Guinot & Richer de Forges (1995: 333) and Garassino (2009: 17). Chave & Malahoff (1998) listed the taxon but without more precise data (only as “Hawaiian Islands”). This species was collected at numerous locations at French Frigate Shoals. Due to permit limitations, we were allowed to keep only a few of the many specimens collected. Our report is the first for this species in the outer Hawaiian Islands.
