As. Harold et al., CREAGRUTUS HYSGINUS (TELEOSTEI, CHARACIFORMES), A NEW SPECIES OF CHARACID FROM NORTHEASTERN VENEZUELA, SUCRE STATE, Copeia, (4), 1994, pp. 975-979
A new Ceagrutus species is described based on material from rivers dra
ining into the Gulf of Paria, northeastern Venezuela. The species is d
istinguished by putatively derived characters of pigmentation of the f
ins, including a brilliant red adipose fin and the presence of dark pi
gment on only the lateral, unbranched ray of the pectoral fin. Other c
haracters which, in combination, serve to distinguish C. hysginus incl
ude the presence of hooks on only the first two or three anal-fin rays
, nine or 10 anal-fin rays, and a rounded or blotchlike humeral mark.
