HUBBSICHTHYS LAURAE, new species 



Figure 13 



Mollienisia caucana Gabaldon (in part), Journ. Parasit., vol. 21, No. 4, pp. 

 311-312, 1935 (Pampdu, Trujillo, Venezuela). 



Holotype. — U.S.N.M. No. 120999, a specimen, 14 mm. in standard 

 length, collected near Pampan, Estado de Trujillo, Venezuela, by 

 Dr. Arnoldo Gabaldon, in 1935 and probably in Rio Motatdn drainage. 



Figure 13. — Hubbsichthys laurae, new genus and species: Holotype (U.S.N.M. No. 120999), 

 14 mm. in standard length. Drawn by Mrs. Aime M. Awl. 



Description. — Certain detailed measurements and counts were made 

 on the holotype and these data are recorded in table 14. 



In addition to the characters recorded in the generic description, 

 in the key, and in the table, the following is given: Eye about 1.2 or 

 1.3 in the flat interorbital space; head 3, depth 3.5, in standard 

 length; pectoral fins not quite reaching to opposite anal origin but 

 past middle of pelvics, the tips of latter extending a trifle past anal 

 origin; caudal, anal, and pectoral fins with posterior margins rounded; 

 the second ray of pelvic is longest; caudal fin scaled about one-third 

 to two-fifths out from its base. 



Coloration. — General color in alcohol brownish, with a darker band 

 along midsides, somewhat broken by pale centers of scales; anal with 

 a black spot near middle of fin on posterior rays. 



Remarks. — This new species may be distinguished from all other 

 related forms of cyprinodont fishes by means of the key. It differs 

 in regard to free margin of eye, forward slant of anterior edge of 

 preorbital, crowded scales on breast, origin of dorsal in front of that 

 of anal, and in coloration. 



Named laurae, in honor of Laura Clark Hubbs (Mrs. Carl L. Hubbs).
