Leptadrillia Woodring 1928
No full textGenus Leptadrillia Woodring, 1928 Type species: Turris (Surcula) parkeri Gabb, 1873 by original designation (Pliocene, Dominican Republic and Jamaica). Diagnosis. According to Woodring (1928: 159–160), shell glossy, very slender with a narrow aperture and long, narrow anterior canal with a very shallow notch. Protoconch of approximately 2 smooth whorls, the last slightly bulging. Teleoconch whorls slightly convex, suture appressed; sculpture of narrow ribs that extend from suture-tosuture on the spire, and to the columella on the body whorl, only slightly reduced and recurved in the area of the anal fasciole. Varix set back a distance from the anal sinus. Spiral sculpture mostly absent, limited to threads or ridges on the anterior fasciole. Anal sinus near suture, U-shaped, wide; stromboid notch shallow. Inner lip narrow, edge detached; with a heavy callus on the parietal wall at the anal sinus. Key characteristics. The combination of the following characteristics distinguishes Leptadrillia from other TWA drilliid genera: 1. Shell small, glossy, usually less than 15 mm, slender (range of average species W/ L ratio = 0.308–0.360) with a narrow aperture and long anterior canal; 2. Ribs almost always extend from suture-to-suture and to anterior fasciole on last whorl, slightly reduced and recurved on whorl shoulders; 3. Shell surface smooth, spiral sculpture limited to ridges or threads on and sometimes near anterior fasciole; and 4. Varix rib-like, but wider and higher; positioned approximately ¼–½-turn from the edge of the outer lip, i.e., not visible when shell is viewed ventrally. Similar genera. Syntomodrillia Woodring, 1928 is also glossy with ribs suture-to-suture except that it has spiral grooves or threads between ribs, a shorter anterior canal, and a wider aperture. Threads or grooves may be very faint or even variably absent in some species of Syntomodrillia, but the shorter anterior canal will often distinguish members of this genus. Splendrillia Hedley, 1922 differs in possessing a short anterior canal, ribs that only extend to the sulcus not to the suture, and a hump-like varix. Distribution. Leptadrillia is distributed throughout the TWA on soft bottoms in moderately deep (50 m) to bathyal depths. Species ranges are poorly known because of their scarcity in collections and because of the unreliability of identifications in published accounts. Confirmed general localities of species treated in this work are shown in Plates 118–119.Published as part of Fallon, Phillip J., 2016, Taxonomic review of tropical western Atlantic shallow water Drilliidae (Mollusca: Gastropoda: Conoidea) including descriptions of 100 new species, pp. 1-363 in Zootaxa 4090 (1) on page 213, DOI: 10.11646/zootaxa.4090.1.1, http://zenodo.org/record/26329
Cerodrillia carminura Dall 1889
No full textCerodrillia carminura (Dall, 1889) Drillia thea var. carminura Dall, 1889 a: 91: Maury (1922: 151). Cerodrillia thea (Dall, 1889) (as synonym of): Abbott (1974: 271); Rios (2009: 311). Not this species or unconfirmed reports. Cerodrillia carminura (Dall, 1889): Williams (2005, 2006, 2009: species 1520). Type material. Holotype (by monotypy), 11.5 x 4.0 mm (USNM 93970). The specimen has not been examined for this work, has been missing since at least 26 Jul 1965 (note in specimen tray), and has not been illustrated or photographed. According to Dall (1989: 91) two specimens from a Blake expedition off Barbados “appear to be of the same sort” but were “dead and faded”. These two are in MCZ 7074, labeled as syntypes of Drillia thea var. carminura, are excluded from the type series on account of Dall’s expressed uncertainty about their identity (ICZN 2000 Article 72.4.1). These two Barbados specimens have been incorporated as paratypes of Splendrillia abdita, new species, in this work and are shown in Plate 142, Figs. 3–4. Type locality. USFC Sta. 2402, Gulf of Mexico, 28 ° 36 '00"N, 85 ° 33 ' 30 "W [between Mississippi R. delta and Cedar Keys, approximately 120 km SSW of Cape San Blas, W Florida], in 111 fms [203 m]. Range and habitat. Known only from the holotype. Description. The following description is given by Dall: "A still paler form [than Cerodrillia thea (Dall, 1884)] without any band was dredged by the U.S. Fish Commission in 111 fms, in the Gulf of Mexico, at Station 2402. In this specimen the nucleus was of a lovely bright carmine color. This form, which is probably peculiar to deep water, may take the varietal name of carminura. It has seven whorls beside the nucleus, of a lemonade color, with nine ribs on the penultimate whorl, rather straighter than in the type [of C. thea] and less swollen on the periphery.” Remarks. Nomenclature. This species was described without illustration as a deep-water form of Cerodrillia thea (Dall, 1884), being paler, slimmer, of a lemonade color and having a carmine-colored protoconch (Dall, 1889 a: 91). The specimen illustrated by Williams has not been examined for its possible agreement with Dall’s description and as such is a candidate neotype.Published as part of Fallon, Phillip J., 2016, Taxonomic review of tropical western Atlantic shallow water Drilliidae (Mollusca: Gastropoda: Conoidea) including descriptions of 100 new species, pp. 1-363 in Zootaxa 4090 (1) on page 63, DOI: 10.11646/zootaxa.4090.1.1, http://zenodo.org/record/26329
