Fusolatirus suduiraudi: As Latirus cloveri (Snyder)
Shell medium size for genus, fusiform, length of adult specimens from 48.1 mm to 64.5 mm. Siphonal canal short, narrowly open, curved, often twisted away from aperture. Smooth pearly white protoconch of 1,25 to 1,5whorls, with 8-9 additional whorls. Sculpture begins on first teleoconch whorl, which is also pearly white; balance of teleoconch colored light tan to brown. Teleoconch sculpture of 7-8 narrow axial ribs per whorl with sharply angular nodes a t shoulders crossed by numerous fine spiral cords, axial ribs streaked white and dark brown, shoulder nodes usually white. Suture deeply impressed with imbricate scaly projections from abapically contiguous whorl. Aperture ovate, lirate within, interior of aperture pink to purple-brown with about 25-30 lirations stopping short of smooth labral margin. Lip moderately thick with minute dentations terminating in internal lirations. Columella smooth with one reasonably prominent plica at abapical end of aperature by canal; small ridge on lip approximately opposite plica.

This species was figured and discussed by SPRINGSTEEN AND LEOBRERA (1986: 332, pl. 94, fig. 12) as "Fasciolaria" walleri Ladd, 1976 (teratological) although they mention that "it may represent a good taxon." These authors state that it is "almost morphologically indistinguishable" from Fasciolaria walleri (Figs. 3, 4) which they redescribe from Recent material (177, pl. 47, fig. 17). However, apart from the shoulder nodules, which are more rounded and less prominent in F. walleri,, and the suture, free of the scaly projections in F walleri ,there are other differences worth noting. The color pattern of F. walleri is a random mix of segments of brownish axial stripes and vertical stripes, especially on the body whorl, against a pale brown background color; the coloration is much less pronounced than in L. cloveri. The canal of F. walleri is proportionally longer, straighter and often more strongly recurved than in L. cloveri.
The status of Fasciolaria walleri deserves comment. LADD (1976: 133, figs. 16-20) described this species based upon Pleistocene material from the New Hebrides Islands, and placed it in the subgenus Pleuroploca. Subsequently (LADD, 1982:47) he transferred the species to Siphonofusus [Buccinidae], while noting a superficial resemblance to the fasciolariid genus Granulifusus. Later, BEETS (1987:90) placed this species in Buccinulum (Euthria) [Buccinidae] and described a subspecies B. walleri sedanense. These placements were based on fossil material. This species was subsequently discovered living in the Philippine Islands (SPRINGSTEEN AND LEOBRERA, 1986:177, pl. 47, fig. 17). Although this species has been collected alive, no soft parts have been preserved and no definitive generic or familial placement can be made at this time. One subadult specimen was obtained with an operculum which presumably corresponds to the shell. This operculum, ovate and corneus, light brown, size and shape corresponding to aperature, with terminal nucleus, is consistent with assignment as a fasciolariid, as is the dentate lip (which buccinids of this size lack) and the lack of determinate growth.
The final generic placement of Latirus cloveri is also problematic. At the begin¬ning of the siphonal canal there is a ridge on the inside of the lip, reminiscent of Siphonofusus lubrica (Dall, 1918), the type of Siphonofusus [Buccinidae]. The shell of L. cloveri is not entirely consistent with placement in either Latirus or Fusinus although it is apparently a fasciolariid. One should also note the dentate lip and the lack of determinate growth. GOFAS (2000: 15) has noted that columellar folds may not be an absolute differentiator for the genera Fusinus and Latirus.

Distribution: Latirus cloveri has been collected in tangle nets at various locations in the central Philippine Islands.Type locality: Aliguay Island, off Dipolog, northwest Mindanao, Philippine Islands.
Type material: Holotype ANSP 408331, length 52.7 mm, in tangle nets, depth 150 m. Paratype 1, MNHN, length 40.4 mm, subadult, in tangle nets, Balicasag Island, Bohol, Philippine Islands. Paratype 2, SC, length 49.6 mm, from type locality. Paratype 3, SC, length 48.1 mm, from type locality.
Other material examined: 1 adult specimen 64.5 mm and 3 immature specimens, 34.2 mm, 38.7 mm, 43.3 mm, the first apparently live collected, all SC. 38.7 mm specimen from type locality; others from tangle nets off Panglao, Bohol, Philippine Islands.
Etymology: The species is named for Phillip Clover of Glen Ellen, California, a friend and shell dealer, who provided much of the type material.
