説明

A pyramidellid species which is ectoparasitic on Conus (Rhizoconus) okamotoi (Kuroda & Ito, 1961), C. (Rhizoconus) sazanka yoshioi Azuma, 1973, and C. (Virroconus) flavidus Lamarck, 1810 in Kii Peninsula, Izu-shichito Islands, and Southwest Shikoku has been recognized for several times. Although this species has been treated as Coneodostomia okamurai Habe, MS., it has not been described in due form to date. This paper describes it as a new species Boonea okamurai. Main conchological characters of this new species are, small and ovate thin shell with almost no sculpture on its outer surface, extremely large body whorl, possessing an oblique and strong columellar fold.
