Pyramidellidae incertae sedis:

Pyramidellidae incertae sedis is a placeholder name for a genus of sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.[1]

Pyramidellidae is the name of the family. "Incertae sedis" means "of uncertain placement". This placeholder name is intended to imply that it is not yet clear which genus or genera these species will eventually be placed in.

Species[edit]

Species within the genus Pyramidellidae incertae sedis include:[1]

Pyramidellidae:

Pyramidellidae, common name the pyram family, or pyramid shells, is a voluminous taxonomic family of mostly small and minute ectoparasitic sea snails, marine heterobranch gastropod molluscs or micromolluscs.

The pyram family is distributed worldwide with more than 6,000 named species in more than 350 nominal genera and subgenera.[2]

This family of micromollusks has been little studied and the phylogenetic relationships within the family are not well worked out. There is a absence of a general consensus which species belong to a specific genus or subgenus, contributing to much confusion. Schander (1999) names more than 300 supraspecific names. [3] As there has been no serious generic revision of the genera worldwide, generic polyphyly can be expected to be rampant throughout the family. However, the family itself is deemed monophyletic. [4]

The family is currently divided into 11 subfamilies (Ponder & Lindberg 1997).[5] An alternative interpretation is that the family Pyramidellidae is but one of six families within the superfamily Pyramidelloidea (Schander, van Aartsen & Corgan 1999).[6] Many species are rare or infrequently recorded.

Distribution

This family is found worldwide, but many species are only found in relatively small geographical ranges. The species found at the Cape Verdes are mainly endemic species. [10]

Shell description

The length of the slender, elongated (turreted or conical) shells varies between 0.5 mm and 3.5 cm, but most species in the family have shells which are smaller than 13 mm.

The texture of these shells is smooth or sculptured in various forms such as ribs and spirals. Their color is mostly white, cream or yellowish, sometimes with red or brown lines.

The shell of these snails has a blunt, heterostrophic (i.e. whorls appear to be coiled in the opposite direction to those of the teleoconch) protoconch, which is often pointed sideways or wrapped up. The teleoconch is dextrally coiled, but the larval shells are sinistral. This results in a sinistrally coiled protoconch.

The columella has usually one, but sometimes several, spiral folds. The aperture is closed by an operculum.

The operculum is ovoid and paucispiral, with the apex anterior, a thread-like arcuate ridge on the proximal side, the inner margin notched in harmony with the plaits of the pillar when prominent.

Life habits

The Pyramidellidae are ectoparasites, feeding mainly on other molluscs and on annelid worms, but some are known to feed on peanut worms and crustaceans.[11][12] A few species in the family Pyramidellidae, such as Otopleura mitralis, are symbiotic with sea anemones, such as Neoaiptasia morbilla [13]

They do not have a radula. Instead their long proboscis is used to pierce the skin of its prey and suck up its fluids and soft tissues. The eyes on the grooved tentacles are situated toward the base of the tentacles. These tentacles have a concave surface. Between the head and the propodium (the foremost division of the foot), a lobed process called the mentum (= thin projection) is visible. This mentum is slightly indented in midline.

These gastropods are hermaphrodites, laying eggs in jelly-like masses on the shell of its host. Some species have spermatophores.[14][15][16]

Miraldella:

Miraldella is a genus of very small sea snails, pyramidellid gastropod mollusks, or micromollusks. This genus is currently placed in the subfamily Chrysallidinae of the family Odostomiidae. The genus was first described as a subgenus of Miralda A. Adams, 1863, but was later given full generic status by Schander et al. (1999).

Shell description[edit]

The original description by Bartsch (1955) states that the shells of the genus are very minute and have strong axial ribs extending from the summit to a deep peropheral sulcus, continuing as slender threads over the base. The spiral sculpture consists only of a very strong subperipheral nodulose chord.

Life habits[edit]

Little is known about the biology of the members of this genus. As is true of most members of the Pyramidellidae sensu lato, they are most likely to be ectoparasites.

Species[edit]

Species within the genus Miraldella include:

  • Miraldella gordonae (Bartsch, 1955) (Type species) (as Miralda (Miraldella) gordonae)
This list is incomplete; you can help by expanding it.
