A revision of the Neotropical spider genus Nops MacLeay (Araneae: Caponiidae) with the first phylogenetic hypothesis for the Nopinae genera Author Sánchez-Ruiz, Alexander Author Brescovit, Antonio D. text Zootaxa 2018 2018-06-01 4427 1 1 121 journal article 29978 10.11646/zootaxa.4427.1.1 c87fedef-eea4-42c6-998a-2a01b2c5839d 1175-5326 1271779 A13A4AB4-0E53-463B-A835-72C193728BB5 Nops branicki ( Taczanowski, 1874 ) Diops branickii Taczanowski, 1874 : 73 , pl. 2, fig. 2. Female holotype from Cayenne, French Guyana (no more data), (depository unknown; not examined). Hasselt, 1887 : 85 , pl. 6, figs 5–6. Petrunkevitch, 1911 : 133 . Roewer, 1942 : 316 . Nops branicki : Bonnet, 1956 : 1475 (emendation of N. branickii ). Remarks . The holotype is apparently lost. The World Spider Catalog (2018) records male and female as known, but actually Taczanowski only described a unique female (see Taczanowski, 1874 , p. 19). Hasselt (1887) also only made reference to the female described by Taczanowski, and argued that it could be an immature male (see Hasselt, 1887 : p.77). He suggested to transfer it to the genus Nops by the number and position of the eyes. Hasselt also suggested the possibility that Diops branickii is synonymous with Nops variabilis : Même il me semble, que la Diops branickii Tacz. n ′est qu ′un individu bien jeune de la Nops variabilis Keys. (see Hasselt, 1887 , p. 84). Petrunkevitch (1911) in his catalogue, apparently without examining the specimen involved, only accepted Hasselt´s first suggestion, and transferred Diops branickii to Nops . During this study no additional material was located.
