Abstract
Two new species of Chrysopathes are described, C. oligocrada from Yucatan and Brazil, and C. micracantha from the
southeastern coast of the U.S. and Brazil. Chrysopathes oligocrada is characterized by lateral pinnules mostly 7–8 mm
long (to 2 cm); 18–21 primary pinnules per cm; anterior-most primary pinnules with no more than one secondary pinnule
(absent on some); some posterior primaries with a single secondary pinnule; lateral primary pinnules usually simple,
rarely with a single subpinnule; tertiary pinnules absent; pinnular spines to 0.07 mm. This species is similar to C. formosa
Opresko 2003 from the Pacific; the latter species differing in density of pinnulation (15–18 per cm) and size of the
spines (to 0.16 mm). Chrysopathes micracantha is characterized by lateral pinnules mostly 5–6 mm long (to 2 cm); 24–
33 primary pinnules per cm; anterior and posterior primary pinnules with as many as two subopposite secondary pinnules;
lateral primary pinnules usually simple but with subpinnules on the thicker branches and stem; tertiary pinnules
rarely present; pinnular spines to 0.1 mm. Chrysopathes micracantha is similar to C. speciosa Opresko 2003 from the
Pacific, the latter species differing in a greater number of secondary pinnules per primary (three or more) and in size of
the spines (to 0.18 mm).
