«Comparison.— The present species [Mirapecten boutetorum] has been identified incorrectly in the past (Dijkstra, 1989: 15; Rombouts, 1991: pl. 15 fig. 6; Raines & Poppe, 2006: 125) as Gloripallium spiniferum (Sowerby 1st, 1835), also known from French Polynesia. Both coral-dwelling species are rare and only very few specimens have been collected alive, probably due to the habitat. Immature specimens could easily be confused with other species, especially single immature right valves. Mirapecten boutetorum spec. nov. differs morphologically from G. spiniferum (see Waller, 1978: 4, pl. 4 figs 58-63) by having 6 radial plicae on both valves (G. spiniferum has 7 on the lv, 8 on the rv), by having more widely spaced scales on the plicae of the left valve (more closely set in G. spiniferum), by lacking macrosculpture on the auricles of the left valve and on the posterior auricle of the right valve (radial macrosculpture is present in G. spiniferum), and by having commarginal microsculpture on the auricles and radial interspaces, at least in the late growth stage (radial microsculpture on the plicae and interspaces in G. spiniferum).»

«Mature Gloripallium pallium is highly distinctive and is approached in morphology only by G. spiniferum (G. B. SOWERBY 1st, 1835, p. 110) , a rare species from the Tuamotu Islands that has seldom been reported since the time that it was described and figured by REEVE (1853, species 118). The type in the British Museum is represented by a well-preserved pair of valves measuring about 23 mm in height and length (Figures 58 - 63). The specimen differs from G. Pallium in having a thinner, Iess convex, nearly unpigmented shell bearing only 10 primary plicae. Whereas the plicae of G. pallium have no more than 3 radial costae on their crests and generally only 2 in the interspaces between plicae, G. spiniferum has closely but evenly spaced costae covering both plicae and interspaces, with up to 10 atop the plicae and 10 in each interspace. Because of the greater number of costae, the stronqly projecting squamae atop the plicae of G. spiniferun are multiply fluted rather than trifid as in G. pallium. ln addition, the hinge line of G. spiniferum is shorter relative to length of disk (ratio CF/AG = 0.50) than that of G. pallium (Table 5). That G. spiniferum is indeed a congener of G. pallium is indicated by the common ocurrence of the thickenings on the interiors of the auricles (Figures 60, 63) and by the identical morphogeny of plicae and microsculpture.»
