Species that contain: Astyanacinus and multidens [ 2 ] records

bopiensis, Astyanax Ruiz-C. [R. I.], Román-Valencia [C.], Taphorn [D. C.], Buckup [P. A.] & Ortega [H.] 2018:16, Fig. 7 [European Journal of Taxonomy No. 402; ref. 35787] Lower Bopi, Colorado River, Bolivia. Lectotype: CAS 38955 [ex IU 17323]. Paratypes: CAS 236977. Replacement name for Astyanacinus multidens Pearson 1924, secondarily preoccupied in Astyanax by Astyanax multidens Eigenmann 1908, but no longer needed as both species are again in different genera (ICZN Art. 59.4). Catalog number for lectotype selection was miscited as CAS 39955. •Valid as Astyanax bopiensis Ruiz-C., Román-Valencia, Taphorn, Buckup & Ortega 2018. •Synonym of Astyanacinus multidens Pearson 1924 -- (Dagosta 2024:93 [ref. 40817] unneeded replacement name). •Synonym of Astyanax multidens (Pearson 1924) [unneeded replacement name]. Replacement Name. Current status: Synonym of Astyanax multidens (Pearson 1924). Characidae: Stethaprioninae. Habitat: freshwater.

multidens, Astyanacinus Pearson [N. E.] 1924:41, Pl. 9 (fig. 4) [Indiana University Studies v. 11 (no. 64); ref. 3396] Río Colorado, Lower Bopi, Bolivia. Lectotype: CAS 38955 [ex IU 17323] [mixed with paratypes]. Paralectotypes: CAS 38955 [ex IU 17323] (16, with lectotype); ?MCZ 20826 (1), 21064 (1), and 89559 (27); ?UMMZ 66510 (6). Additional original material: CAS 60728 [ex IU 17324] (2), 60729 [ex IU 17325] (1), 60730 [ex IU 17326] (1). Replaced by Astyanax bopiensis Ruiz-C., Román-Valencia, Taphorn, Buckup & Ortega 2018, but the two species are no longer secondary homonyms, so the original name has to be restored (ICZN Art. 59.4). Lectotype selected by Ruiz-C. et al. 2018:16 [ref. 35787]. •Valid as Astyanacinus multidens Pearson 1924 -- (Chang & Ortega 1995:2 [ref. 24302], Lima in Reis et al. 2003:107 [ref. 27061], Bertaco et al. 2010:266 [ref. 30864], Barriga Salazar 2014:106 [ref. 35745], Sarmiento et al. 2014:183 [ref. 35004], Dagosta 2024:93 [ref. 40817]). •Synonym of Astyanax bopiensis Ruiz-C., Román-Valencia, Taphorn, Buckup & Ortega 2018 -- (Ruiz-C. et al. 2018:16 [ref. 35787]). •Valid as Astyanax multidens (Pearson 1924) -- (Meza-Vargas et al. 2021:17 [ref. 39298], Ruiz-C. et al. 2023:199 [ref. 40361]). Current status: Valid as Astyanax multidens (Pearson 1924). Characidae: Stethaprioninae. Distribution: South America: upper Madeira River drainage, western Amazon River basin (Bolivia and Peru). Habitat: freshwater.
