Abstract
A new, small, saddle-shaped species of Chrysochromulina with a coiling haptonema is described from Danish coastal waters. The scale cover of C. ahrengotii sp. nov. comprises an inner layer of plate scales and an outer layer of spine-bearing scales. Chrysochromulina ahrengotii bears close morphological resemblance to C. scutellum Eikrem et Moestrup, another species of Chrysochromulina recently described, but differs in details of the scales and in having only one type of spine scale. Details of the flagellar apparatus and some observations on scale formation are reported. The spine scales are formed in T-shaped cisternae of the Golgi apparatus, a very unusual feature somewhat resembling the formation of the flat scales in C. chiton Manton seen by Manton in 1967. The flagellar apparatus is similar to that of other saddle-shaped species such as C. scutellum, C. simplex Estep, Davis, Hargraves et Sieburth, C. apheles Moestrup et Thomsen, and C. acantha Leadbeater et Manton. Chrysochromulina ahrengotii is a fairly common species in Danish waters and appears to be euryhaline, occurring at salinities between 8 and 30 psu. The temperature range at which it occurred was 10° to 23°C.
