Interchangeable taxa

Carinapex papillosa (Garrett, 1873) is similar only to Carinapex albarnesi n. sp. in which both are spindle-like. Carinapex papillosa is large sized, with orange banding, apex acute, narrow, obtaining a height of 0.3 mm, whorl profile elevated at periphery, teleoconch whorls with two equal sized, tightly spaced dash-like nodules, final two whorls with three rows. Carinapex albarnesi is very large sized, with brown banding, apex wide, first protoconch whorl flatly domed, wide slopes, obtaining a height of 0.5 mm, whorl profile low, sunken, whorls with two widely spaced, large, horizonally ovate nodule rows, sutural row less distinct, peripheral prominent. The description of Mangilia (Glyphostoma) dialitha (Melvill & Standen, 1896) appears to be synonymous with C. papillosa based on the original description and with regards to the close proximity of the type locality. Kay (1979), Cernohorsky (1983), Sysoev in Poppe (2008), Cox & others (2009) and Severns (2011) all had inadvertently lumped various new species under the name C papillosa without comparison to the known holotype of C. papillosa.

C. papillosa was described from Tahiti. It also occurs on Hawaii and in Indonesia.
