TABLE 2. Comparison of meristic characters of male and female Chavturia abyssopelagica n. sp., Halocypris parvirostrata Chavtur & Stovbun, 2008, H. profunda n. sp. and H. striata (Müller, 1906). Characters that distinguish C. abyssopelagica from the Halocypretta species are italicised, and those that in combination distinguish between the three Halocypretta species are emboldened.
