As well as the new Channa two more fish species are described in this issue. Copies of the papers would be much appreciated as always!

A new species of Brycon (Characiformes: Characidae) from Nicaragua and Costa Rica, with a key to the lower Mesoamerican species of the genus.

Abstract

A new species of Brycon is described from the Atlantic slope of Nicaragua and Costa Rica. Brycon costaricensis n. sp.
differs from all other Central American Brycon species by the following combination of characters: 49 to 54 scales in the
lateral line; 5 or 6 rows of scales between lateral line and pectoral fin base; 9 to 11 rows of scales between lateral line and
dorsal fin base; 5 to 7 rows of scales between lateral line and anal fin base; anal fin notably longer than head, with 33 to
37 total rays; and a elongated and shallow caudal peduncle, whose length is 1.78 to 2.35 times its depth. A key to lower
Mesoamerican species of the genus is also presented.

Geophagus crocatus, a new species of geophagine cichlid from the Berbice River, Guyana, South America (Teleostei: Cichlidae).

Abstract

We describe a new Geophagus from the Berbice River of Guyana, bringing the total number of described species in the
genus to 19, and of Guianese species to six.. Geophagus crocatus, new species, is distinguished from all species of Geophagus
outside of the G. surinamensis group by the presence of an incomplete suborbital stripe (vs. complete), and the presence
of six lateral bars, with bars 2 and 3 slightly sloping toward each other and fusing dorsally at the base of the dorsal
fin. Geophagus crocatus is the only Geophagus species known from the Berbice River, and it is present above and below
the Itabru Falls.
