Maximum depth of body 23% of standard length. Caudal peduncle short and high, its 

 length 23%, its depth 48% of standard length. 



Genital papilla small. In male, papilla slender with a posterior projection: margin of ge- 

 nital orifice serrated; ventral surface smooth without skin fold. In female, genital papilla 

 short and broad without posterior projection; margin of genital orifice serrated. 

 Pectoral fin fan-like; sharper in female: with 13-16 rays, usually 14 or 15. Pelvic fin ori- 

 ginates in advance of dorsal fin origin: prepelvic length 49% of standard length; pelvic 

 rays usually eight, seven in two of the 1 6 specimens counted. 



Dorsal fin originates posterior to pelvic fin origin, predorsal length 57% of standard length. 

 117% of prepelvic length: with two procurrent rays and eight rays, occasionally seven 

 (two of the 16 specimens counted with seven rays). Anal fin originates under or slightly 

 behind insertion of dorsal fin, with one or two procurrent rays and 7-8 rays, mostly eight, 

 only one among 16 specimens with seven rays. Caudal fin shallowly forked, lobes round 

 or somewhat acute: with 9-11 dorsal procurrent rays. 7-10 ventral procurrent rays, and 19 

 (10+9) principal rays. 



Small individuals (< 20 mm standard length) lack cephalic lateral line pores. Left and 

 right supratemporal canals short without connection between each other, with six pores. 

 Otic canal with six pores. Supraorbital canal with an interruption, 10 pores. Infraorbital
