Gymnotiformes (Knifefishes) >
Sternopygidae (Glass knifefishes)
Etymology: Eigenmannia: From Eigenmann, 1910, researcher of faunistic studies (Ref. 45335); desantanai: Named desantanai in honour of Carlos David de Santana, in recognition of his contributions to our knowledge of the Gymnotiformes (Ref. 115689).
Eponymy: Professor Dr Carl Henry Eigenmann (1863–1927) was a German-born American ichthyologist. [...] Dr Carlos David de Santana is a Brazilian ichthyologist who is presently a post-doctoral fellow at the Smithsonian. [...] (Ref. 128868), visit book page.

شعاع نرم باله مخرجي: 170 - 198. Diagnosis: Eigenmannia desantanai can be distinguished from other species in the E. trilineata species group by the inferior medial stripe, which is 1 scale deep (versus 2 or 3 scales deep); Eigenmannia desantanai can be further distinguished from the other members of the species group, except for E. waiwai, by the 11 or 12 precaudal vertebrae (versus 13 or 14 in E. antonioi; 15 in E. guairaca, E. muirapinima, and E. vicentespelaea; 13 in E. matintapereira; 14 or 15 in E. microstoma and E. trilineata; and 13–15 in E. pavulagem); Eigenmannia desantanai can be differentiated from E. waiwai by the terminal mouth (versus subterminal); the orbital diameter 14.5– 19.6% HL (versus 22.6–28.8%); the length of the anterodorsal process of the maxilla equal to 50% of the width of the posterior nostril (versus 1.5 times the width of the posterior nostril); the depth of the posterodorsal expansion on infraorbitals 1 + 2 approximately equal to the total length of infraorbitals 1 + 2 (versus less than 50% of the length of infraorbitals 1 + 2); and by the dentition pattern of the dentary with 21–23 teeth distributed in 2 rows (outermost row with 10 to 12 teeth; innermost row with 9 to 13 teeth) [versus 37 or 38 teeth distributed in 4 rows (outermost row with 7 teeth; 2nd with 11–15 teeth; 3rd with 8 to 15; innermost row with 4 to 8 teeth)] (Ref. 115689).
