Comments

Taxonomy from Skrzycka, 2014.
Coccolepis aniscowitchi Gorizdro-Kulczycka 1926 has been ascribed to the genus Morrolepis, including the junior synonyms Coccolepis socialis, Coccolepis cockerelli and Coccolepis martynovi (Skrzycka, 2014).
Emended diagnosis for M. aniscowitchi from Skrzycka 2014, p.15 “Morrolepis having parietal with a slender anterior part extending for two-thirds of its length, with a prolonged antero-medial corner. Amioid scales sensu Schultze (1996) with denticles on posterior margin. Lateral line scales with serration on posterior edge. Maxilla with a prominent postero-ventral corner. Small and irregularly spaced teeth, some minute.”
