Description
Turris guidopoppei sp. nov.
Plate 16, figs A–G
Pleurotoma garnonsi [sic]; Weinkauff 1875: 12, pl. 2, figs 3–4.
Turris garnonsii (non Reeve, 1843); Powell 1964: 329, pl. 181, fig. 18 (as “slender form”); Vera-Peláez, Vega-Luz & Lozano-Francisco 2000: 10, pl. 8, figs 9–11; Olivera 2000: pl. 1, fig. 8; Olivera & Sysoev 2008: pl. 681, figs 6–7; Robin 2008: pl. 448, fig. 7.
DESCRIPTION: Shell very narrowly fusiform, b/l 0.20–0.22; a/l 0.44–0.48; siphonal canal very long, slender and slightly recurved terminally; suture shallow, whorls convex anteriorly, subsutural region shallowly-concave; outer lip moderately convex, anal sinus deep, linguiform, parallel-sided; interior of aperture with 13–14 spiral ridges.
Subsutural region without a distinct cord, but with a complex of ridges, consisting of two pliculate threads at suture, followed by a very thin, but stronger dark ridge. Sulcus ill-defined and sloping, containing 2–3 crenulated spiral threads. Sinus cord low, distinctly bifid, posterior margin slightly tabulate. Base of spire whorls with three main spiral cords, the upper (peripheral) cord prominent and angular, situated at mid-whorl, lower two narrower and weaker, each interval with a fine thread. Upper base of last whorl with 7–9 widely-spaced angular cords, each interval with a fine thread; rostrum with ca 10 fine, rough, subequal ridges. Relatively weak collabral threads are visible mainly in intervals, rendering interstitial threads crenulated.
White with orange-brown squares or rectangles in subsutural area and a similarly coloured zone at parietal region, main cords and some of the finer ones spotted or flecked with dark brown.
Attains 89.6 mm.
Protoconch narrow, slightly cyrtoconoid, of ca 5 smooth whorls (Vera- Peláez et al. 2000).
DISTRIBUTION: Philippines, in 20–60 m to New Caledonia.
TYPE LOCALITY: Olango Is., Cebu, Philippines.
TYPES: Holotype (Pl. 16, Figs. A-B) Olango Is., Cebu, PHILIPPINES, 24–40 fath. [44–73 m], by hookah, MNHN 24945, dimensions 94.0 x 19.6 mm,; Paratype 1 (Pl. 16, Fig. C), Bohol Is, PHILIPPINES; 77.8 x 15.7 (MNHN 24436); Paratype 2—same locality, 65.5 x 14.7, (ANSP 426054); Paratype 3, between Olango Is and Bohol Is, PHILIPPINES, dived 20–50 m (NMSA L8199: BO); Paratypes 4–5, same locality, 20–50 m (NHMUK 20119300: BO).
OTHER MATERIAL EXAMINED: PHILIPPINES: 13°55’N, 120°22’E, 20-21m (MNHN); NEW CALEDONIA: 20°40.4’S, 164°14.9’E, 26-40m (MNHN);
REMARKS: In shape, this species superficially resembles a miniature Fusinus (family Fasciolariidae). In colouration it resembles Turris garnonsii (pl. 14, figs A–I), but its shell is much more slender (breadth/length about 0.19–0.22, against 0.25–0.27) and more fusiform with a longer siphonal canal (about twice the aperture length, but subequal to it in garnonsii), and a very strongly undulating profile; its peripheral cord is situated at mid-whorl, while in T. garnonsii it is positioned below the mid-whorl.
ETYMOLOGY: Named in honour of Mr Guido Poppe, who generously provided hospitality and support in the Philippines, during preparation of this manuscript.
