Comments on synonymy. Although Reeve introduced Pecten ustulatus(May 1853)a few months earlier than Pecten gloriosus(Aug 1853), we prefer to use the latter name because of its wide general acceptance. This is further complicated by Reeve (1853: caption to pl. 30, sp. 134, Jun 1853) initially applying the name Pecten nobilisto this species, but later (Reeve, 1853: errata; evidently issued after Figure 90.

As first revisers, we select the name Pecten gloriosusto be used as the valid name for the species named Pecten gloriosus, Pecten testudineusand Pecten ustulatusby Reeve (1853).

Description. Shell rather compressed, up to c. 120 mmhigh, juvenile elongate, adult subcircular, equivalve, equilateral, left valve slightly more convex than right, auricles highly unequal, umbonal angle c. 80–85°; most specimens dark brick red with paler maculations. Both valves sculptured with 22–23 evenly spaced primary radial plicae bearing variably prominent, widely set scales, with secondary squamose interstitial riblets near ventral margin (absent in juveniles). Interstitial microsculpture of irregular antimarginal scratches, weakly developed on central part of disc, more prominent near posterior margin.Anterior auricle of left valve with c. 8 scaly radial riblets; of right valve with 5–6 more prominent riblets. Posterior auricle of left valve with similar sculpture to anterior, although weaker and with fewer riblets. Dorsal margin straight. Resilifer narrowly triangular. Byssal notch deep, byssal fasciole rather broad. Functional ctenolium well-developed, with c. 5 teeth. Interiorfurrowed; internal rib carinae short, prominent around ventral margin. Resilial and dorsal teeth prominent. Dimensions. Illustrated specimens: N QLD, Port Curtis, Rodds Harbour (AM C.069989; scaly, coarsely sculptured specimen): rv: H 77.4, L 74.4 mm; lv: H 76.3, L 73.4 mm; D 26.0 mm; S QLD, trawled off Moreton Island (AM C.081213; weakly sculptured specimen): rv: H 86.6, L 79.3 mm; lv: H 85.7, L 78.7 mm; D 27.9 mm; holotypeof Mimachlamys subgloriosaIredale, AM C.089668 (Fig. 93B, E), QLD, GBR, Low Isles, 16–22 m: H 43 mm, L 40 mm. Habitat. Living in the littoral zone, byssally attached to rocks or coral, or amongst coral rubble on soft sediment (sand and/or mud). In Western Australiaoften attached to pipes or ropes in deeper water, occasionally found attached to ropes hanging under floats washed as far south as Perth (H. Morrison, pers. comm.).
Distribution. Tropical western Pacific, from the Philippinessouthwards to Indonesiaand northwestern, northern and northeastern Australia, eastwards to Tonga(Raines & Poppe, 2006: 272); PhilippinestoAustralia, 17–110 m(Huber, 2010: 211); Philippines, 10–30 m( Raines, 2010: 640; Dijkstra, 2013: 92); Vanuatu, 91–110 m(Dijkstra & Maestrati, 2012: 401). Maximum depth range of live-taken specimens is in the intertidal zone to 110 m.Present specimens from Australiaalive at 3.5– 72 m.
Remarks. Mimachlamys gloriosaclosely resembles Mimachlamys crassicostata(G. B. Sowerby II, 1842)from northern Chinese and Japanese waters. Mimachlamys gloriosacan be distinguished from M. crassicostataby its smaller size ( M. gloriosaup to c. 120 mmin height, M. crassicostataup to c. 140 mm), its different sculpture ( M. gloriosac. 22 plicae with secondary riblets in late growth stage; M. crassicostatac. 24 plicae lacking interplical secondary sculpture), and its colour ( M. crassicostatais more brightly coloured, resembling the colour of M. spinicostata). The eggs and larval development of New Caledonian specimens of M. gloriosawere described by Lefort (1992).
