Description Holotype PROTOCONCH. Smooth, multispiral, whitish-yellowish, consisting of 2.5 whorls. Beset with rows of minute pustules ( Fig. 3M ). SHELL. Elongate-ovate, 5.5 postnuclear whorls, suture impressed. Penultimate whorl with 15 nearly equally pronounced, round ribs; body whorl with 14 ribs, decreasing in height or disappearing on ventral side. Varix broad and strong. SPIRAL CORDS. Continuous, flat and narrow, 7 cords on penultimate, and 11 on body whorl, peripheral one somewhat darker. INTERCORDAL SCULPTURE. Approximately 6 very fine, evenly spaced striae between spiral cords. Fig. 6. Geographical and bathymetrical distribution of Reticunassa visayaensis sp. nov. Star indicates type locality. Each bar represents all lv or dd specimens. APERTURE. Oval, inside outer lip with 9 lirate denticles, peripheral denticle slightly more pronounced. Parietal denticle moderate, anal canal wide. Columellar callus wide, anteriorly somewhat elevated, posteriorly partly extending over whorl; well delineated border. Fine lirae over entire surface. OPERCULUM. Yellowish, serrated. SIPHONAL CANAL. Fasciole strong, siphonal area with 1 strong and 5 weak cords. COLOR. Yellowish, most spiral cords reddish between ribs. ADULT SIZE. 8.5–12.7 mm , usually 8.5–10.5 mm . Remarks The intraspecific variability is considerable. The number of ribs and spiral cords may vary, and the color is extremely variable, white to yellow and orange to brown, unicolor or with narrow or broad yellow, brown, dark brown, or grey bands on all whorls or only on the body whorl. Reticunassa visayaensis sp. nov. has a broader, less pointed protoconch than R. paupera ( Gould, 1850 ) . R. visayaensis sp. nov. also differs from R. paupera by its larger size, its more bulbous shape and its lower ribs, especially on the body whorl, and by usually displaying dark bands. R. visayaensis sp. nov. is very similar to R. tringa . When the protoconch is missing, a positive identification is almost impossible. The protoconch of R. tringa is paucispiral with 1.5–1.75 whorls, whereas R. visayaensis sp. nov. has a protoconch of 2.25–2.5 whorls. The protoconch of R. tringa is nipple-shaped, hence the name “ mamillata ” ( Preston 1907 ); the protoconch of R. visayaensis sp. nov. is dome-shaped. Preston’s description is accompanied by a drawing of the paucispiral protoconch. R. visayaensis sp. nov. is the Reticunassa species most commonly offered in the shell trade from the central Philippines , as well as R. crenulicostata ( Shuto, 1969 ) . The latter is smaller ( 5–7 mm ) and has a large multispiral protoconch of 3.5 whorls ( Cernohorsky 1984 : pl. 38, figs 1–2; Martin 2008 : pl. 354, figs 4–5). These features are the most distinguishing differences between R. crenulicostata and R. visayaensis sp. nov. Reticunassa tringa has a paucispiral protoconch. Identification based on geographical distribution alone ( Fig. 6 ) may be possible in specimens lacking a protoconch or welldefined teleoconch sculpture. Habitat Intertidal to 150 m , commonly from 0 to 20 m . Distribution Philippines , Indonesia and New Guinea ( Fig. 6 ).
