Etymology: Clupeonella: Latin, clupea = sardine, derived from Clupeus = shield; diminutive (Ref. 45335); abrau: abrau taken from Lake Abrau found near the city of Novorossiisk in the northern Caucasus (Ref. 72388).

Max length : 9.5 cm SL पुल्लिंग / अलिंग; (Ref. 188); अधिकतम सूचित उम्र: 2.00 वर्षो (Ref. 72388)
पृष्ठीय रीढ़ (सम्पूर्ण) : 3; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 13 - 21; गुदा कांटा: 3; ऐनल सौफट रेज़: 12 - 23. Body moderately slender, its depth about 19 to 23% of standard length; head short and narrow, interorbital width not more than 17.5% of standard length; belly sharply keeled, with 23 to 26 scutes. Pectoral fin tips pointed. Pterotic bulla absent. No notch at the center of the upper jaw. Last two anal fin rays enlarged.
