252  Volume 14, No.4, December, 2000, INSECTA MUNDI A synonym in the genus Fluda (Araneae: Salticidae) Galiano (1971) revised the genus Fluda Peck-ham and Peckham  1892,  and later updated the revision with additional descriptions, including a new species (Galiano 1986).  In her original revi-sion, she transferred Keyserlingella perdita Peck-ham and Peckham 1892, from Colombia, into the genus. This species was described from both sexes but only the female  was adequately illustrated: Galiano (1971) noted that Banks (1929) had exam-ined only the female type of K.  perdita when he described the Panamanian Fluda princeps from both sexes.  She concluded that the male of K. perdita was lost subsequent to its description but prior to  Banks examination.  If the  male  of K. perdita had been available, it would have made more sense to compare both sexes with F. princeps. I  have been able to confirm that the male of K. perdita, supposed to be at the Museum of Compar-ative  Zoology,  Harvard University,  was  lost  01. Wallach, personal communication, 2001). Another species included in  Galiano's 1971 revi-sion was Fluda usta Mello-Leitao 1940, described only from the male, collected in Guyana. Given that the male of K.  perdita technically was described already,  and there was  no  particular reason to match the male of F.  usta with the female of K. perdita considering that they were described from countries which had Venezuela (a moderately large and quite diverse country) between them, it is not surprising that Galiano (1971) failed to recognize that they might belong together. A  checklist of the Salticidae of Trinidad and Tobago (Cutler and Edwards 2001) lists both spe-cies, which were collected by the authors in Trin-idad.  [No  nomenclatorial changes were made in that list, although it was apparent that some would be needed.]  Complete records are listed below.  At one locality, males and  females were collected in the same habitat.  The similarity in habitus between the two sexes was striking.  The original illustra-tions of the IYlale palp of  K. perdita by Peckham and Peckham (1892) are quite simple, but  what  is present is compatible with the illustrations of F.  usta by Galiano (1971).  It seems highly likely that these two described species (for which only one sex of  each is  adequately or  actually known)  represent the opposite sexes of  one species. Therefore, I make the following synonymy.
