Remarks: Himerometra sol A.H. Clark, 1912b , known from two specimens (NHM-1902.3.13.47) from the Maldive Islands, has proximal pinnules similar to those described for H. magnipinna but supposedly differs in having larger, stouter cirri with middle cirrals longest and at most as long as wide ( Fig. 6 View Figure 6 ). Re-examination of the two known specimens indicates that the proportionately longest middle cirrals are all wider than long (W/L 1.1–1.2). However, morphological features of the holotype do not differ significantly from those attributed to H. magnipinna ( Fig. 5 View Figure 5 ) and, with the inclusion of H. magnipinna within H. robustipinna , no feature separates H. sol as distinct. A.H. Clark (1941) referred to more than one H. robustipinna as having longest cirrals wider than long. We maintain H. sol as a valid taxon because the specimens were collected outside the known range of H. robustipinna and because we have no molecular data.
