Description. Live and preserved animals unknown. Shell to 5.3 mm, presumably internal, globose, oval ( Fig. 12View FIGURE 12 A –F). Apex with an involute spire ( Fig. 12View FIGURE 12 J). Lip not rising above apex. Sculpture of faint growth lines, with no punctuate striae.

Radular formula 8 x 5.1.0.1.5. Innermost lateral teeth hook-shaped smooth, lacking denticles ( Fig. 12View FIGURE 12 I). Outer teeth elongate. Gizzard plates absent.

Reproductive system unknown.

Range. Hawkins Island, Alaska to Isla Cedros, Baja California Sur ( Fig. 3View FIGURE 3 B). Depth range 9–975 m, shallower towards the northernmost part of the range.

Remarks. This species is only known from empty shells found from Baja California to Oregon and empty shells with dried soft parts from southern Alaska and the Gulf of Alaska. Another similar Panamic species, Woodbridgea williamsi Berry, 1953  ( Fig. 12View FIGURE 12 H) is morphologically similar and could constitute a synonym. Because of the absence of anatomical data for Woodbridgea williamsi  we refrain from proposing taxonomic changes at this point.

Similar to Laona confusa ( Ohnheiser & Malaquias, 2013)  from the North Atlantic, both species share a smooth, globose shell, and lack gizzard plates, but Philine hemphilli  has fewer outer teeth. Another similar species in shell morphology is Laona grandioculi ( Ohnheiser & Malaquias, 2013)  from the Lofoten Islands and Finnmark, but it has denticulate radular teeth. Both Laona confusa  and Laona grandioculi  were originally described as Philine  by Ohnheiser & Malaquias (2013) and later transferred to Laona  by Oskars et al. (2015). It is also likely that Philine hemphilli  may be a member of Laona  , based on the radular formula and the similar shell morphology to some members of Laona  . However, Laona  as currently defined, is a morphologically heterogeneous group and further research may result in further splitting. Because of all these uncertainties and the lack of molecular data for Philine hemphilli  we conservatively propose to maintain this species in Philine  sensu lato.
