Radular tooth: Tooth is serrate; terminating cusp is internal; tooth is elongated but the anterior section and the posterior section of the tooth are subequal in length; the blade is fairly long and covers at least half of the anterior section of the tooth; the barb is short; a basal spur is present.
Shell characters: Shells are conical to elongate conical; whorl tops are often concave; nodules usually do not persist; the anal notch is deep to moderately deep; the operculum is small to medium sized; the periostracum is tufted; the protoconch has 2.5 whorls.

Tuckericonus: Diagnosis: Shells small for family, elongated, fusiform, with straight sides; spires of variable height, most often elevated and subpyramidal; shoulders sharply angled, bordered by low, rounded carina; body whorls smooth with silky texture, often faintly sculptured with very fine spiral threads and faint cords; anterior ends of shells encircled by numerous deeply incised spiral grooves; spire whorls smooth, sometimes with few very faint spiral threads; apertures narrow and straight; protoconchs characteristically very pronounced, projecting, needle-like, forming elongated mamillate structure composed of 2 or 3 whorls; shells mostly colored in shades of bright yellow, orange, pink, brown, or red, frequently overlaid with large brown or tan flammules and thin spiral lines, often with large white patches. Type Species: Conus fiavescens Sowerby, 1834, from shallow carbonate sand areas near coral reefs along southeastern Florida, the Florida Keys and northern Cuba, the Bahamas, and south to the Turks and Caicos.Other Species in Tuckericonus: T. flamingo (Petuch, 1980), 60 m depths off southeastern Florida and the Florida Keys; T. ceruttii (Cargile, 1998), Bay Islands of Honduras and the Central Caribbean Banks; T. unnamed species, with a multinucleate protoconch, off south¬eastern Florida.
Discussion: Members of this small but distinctive group of cone shells have traditionally been placed in the genus Dauciconus, primarily because of their general shell shape and colors. Tuckericonus differs from Dauciconus, however, in having consistently smaller, more elongated, and narrower shells, with more projecting early whorls and protoconchs. Members of the new genus lack the heavy spiral cords frequently seen on the spires of Dauciconus species and have more deeply incised spiral grooves around the anterior end. The protoconch structure of Tuckericonus is the most outstanding feature of the genus, being characterized by having unique needle-like projecting whorls that extend well beyond the early whorls of the teleoconch. The genus is confined to the southern end of the Carolinian Molluscan province (Floridian Subprovince) and the Bahamian and Nicaraguan Subprovinces of the Caribbean Molluscan province. The Bahamian and Floridian specimens of T fiavescens may prove to represent two distinct species. If this is the case, then true T. fiavescens would be confined to the Bahamas and the Turks and Caicos and the Floridian species would be refer-able to T. caribbaeus (Clench, 1942) (for specimens named from off Palm Beach County).

Dauciconus contains species with relatively smooth bodies that are conical in profile. Some may have pustulose ridges but most have smooth body whorls. Dauciconus seems to belong to a clade of West Atlantic and East Pacific species that is a sister taxon of a clade containing Hermes and Leporiconus.

These species occur in the West Atlantic and East Pacific regions.
