Description

The length of the shell varies between 5.5 mm and 7.5 mm.

The shell of Pseudorhaphitoma stipendiarii is relatively small, with lengths varying between 5.5 mm and 7.5 mm [1]. Like other species within the genus Pseudorhaphitoma, it is characterized by a claviform (club-shaped) shell, typically monochrome brown or white, with a high spire [3].

General characteristics for the genus Pseudorhaphitoma that likely apply to P. stipendiarii include:

Kilburn's 1993 study, which included the description of P. stipendiarii, provided wide diagnostic information for species within the genus distributed along the southern African and Mozambique coasts, along with notes and photographs for other Indo-West Pacific species [4].

Distribution and Habitat

Pseudorhaphitoma stipendiarii is a marine species found off the coasts of Zululand, South Africa, and Zanzibar [1]. This distribution places it within the warm waters of the Indo-West Pacific biogeographic region, an area known for its high marine biodiversity.

Specific details regarding its preferred habitat depth are not extensively documented in readily available sources, but other species within the genus Pseudorhaphitoma are known to occur in subtidal environments, ranging from low tide levels to depths of around 55 meters [3]. It is likely that P. stipendiarii inhabits similar sandy or muddy substrates in tropical or subtropical coastal waters.

Taxonomy

The genus Pseudorhaphitoma itself was established by O. Boettger in 1895. The type species for the genus is Mangelia fairbanki G. Nevill & H. Nevill, 1875 [5]. The family Mangeliidae is part of the diverse superfamily Conoidea, which comprises a large group of predatory marine gastropods, many of which are known for their venomous harpoon-like radular teeth. However, specific details about the feeding habits or venom of P. stipendiarii are not widely published.

Distribution

This marine genus occurs off Zululand, South Africa and Zanzibar.
