Etymology: From Latin reticulatus (netted); in reference to the cancellate, net-like sculpture.
salpinx may be confused with those of Danilia textilis, but the latter have finer, more regularly cancellate sculpture, a sunken rather than an exsert protoconch and more rounded whorls with a more narrowly channelled suture.
The shell of Vaceuchelus species is small (length <10 mm), predominantly white and has a cancellate or foveolate sculpture.
Nonetheless, they retain a well defined, relatively fine, cancellate sculpture on the last adult whorl and have four and five spiral cords respectively on the base (including that level with suture) as opposed to three in V.
5-2 times as numerous as peripheral projections; interval between peripheral cord/keel and abapical suture progressively deeper and more channelled with growth; development of remaining spirals between adapical suture and periphery variable, sometimes distinct, sometimes obsolete; axial sculpture becoming less obvious with growth; apical whorls (not first) somewhat cancellate, becoming more foveolate with elongate D-shaped pits on later whorls; pliculae in supra-sutural sulcus usually stronger and less close-set than those above peripheral keel.
Diagnosis: Shell small, profile conical with narrowly indented suture; suture level with subperipheral cord; sculpture coarsely cancellate with scale-like projections on spiral cords; columella with a single basal tooth; interior of outer lip thickened and set with ridge-like denticles, that nearest columella largest and separated from basal columella tooth by a U-shaped notch; denticles do not extend into aperture as in-running ridges; umbilical and parietal region covered by glossy inductural callus shield; aperture obliquely tangential to base of last adult whorl; outer lip with low subterminal external varix; protoconch exsert.
informa McLean & Poorman, 1971, from Ecuador; however, this taxon evidently lacks diagonally cancellate protoconch sculpture.
Nevertheless, it is possible that the two taxa may intergrade, as diagonally cancellate sculpture may only develop towards the termination of the protoconch.
philippinensis, Shuto (1971: 18) claimed that the sculpture was diagonally cancellate.
