Nannostomus bifasciatus Hoedeman 



Nannostomus bifasciatus Hoedeman, 1953, p. x30.11.311 (original description, 

 in Dutch; type locality: Berg en Dal at Surinam River, Surinam; holotype 

 in Amsterdam Museum); 1954a, p. 85 (description in English); 1954b, p. 77 

 (description from life). — Sterba and Tucker, 1962, p. 211 (description and 

 aquarium notes). 



Diagnosis. — At least a few perforated lateral-line scales present; 

 about 8+14 gill rakers; iii,9 anal fin rays, secondary horizontal stripe 

 present, scales in a lateral series about 25. 



Note. — This species is known from only four specimens and the 

 original author has kindly sent three of them for examination. The 

 fish was an aquarium import from Surinam to the Netherlands and 

 the three available specimens are in poor condition, two having been 

 dried at one time and all with torn, broken fins and broken jaws with 

 missing teeth. Unfortunately the original description was inadequate 

 and inaccurate, and it is impossible completely and competently to 

 describe or illustrate the fish from the specimens at hand. 



Description. — Body elongate; sides somewhat flattened and body 

 compressed posteriorly. Greatest depth just anterior to origin of 

 dorsal fin. Standard length of longest specimen examined 28.3 mm. 

 Greatest body depth 5.4 (5.3-5.6) [females with ripe eggs not at hand 

 but undoubtedly deeper bodied (see illustrations of live specimens 

 in Hoedeman 1954a and Nieuwenhuizen 1954)]; least depth of caudal 

 peduncle 11.6 (11.4-11.9); length of caudal peduncle 5.6 (5.5-5.6) 

 in females, male damaged. Snout tip to origin of dorsal fiin 1.9 

 (1.9-1.9); snout tip to origin of anal fin 1.3 (1.3-1.3).
