D16D87DF0D1CF7414B6EA0470879F821.taxon	discussion	Remarks. — Rineloricaria jubata and R. magdalenae were originally recorded from the Atrato River by Eigenmann (1922), and subsequent authors (Mojica et al., 2004; Maldonado-Ocampo et al., 2006, 2012) have also listed these two species from the Atrato basin. Maldonado-Ocampo et al. (2006) recognized for the first time a third species of Rineloricaria from this basin, which was positively confirmed by us as R. atratoensis (IAvH-P 7403). However, another record listed by Maldonado-Ocampo et al. (2006) as R. magdalenae (IAvH-P 6760) turned out to be R. atratoensis, thus the presence of R. magdalenae as well as R. jubata in the Atrato River is the subject for confirmation in our ongoing systematic revision of Rineloricaria in Colombia.	en	Castellanos-Mejía, María Camila, Londoño-Burbano, Alejandro, Ochoa, Luz E., García-Alzate, Carlos A., DoNascimiento, Carlos (2024): Two New Species of Rineloricaria (Siluriformes: Loricariidae) from Trans-Andean Rivers of Colombia, Unveiled through Iterative Taxonomy.

D16D87DF0D18F74D483DA314084BFCD8.taxon	discussion	Remarks. — Rineloricaria giua is widely distributed across the middle and lower sections of the Magdalena River, being sympatric and even syntopic with R. magdalenae. However, scarce records of the new species in ichthyological collections in Colombia suggest that populations of R. giua are less abundant when compared to the ubiquitous specimens of R. magdalenae. Morphometric analysis. — The PCA analysis shows broad overlap of all species, with the first two axes accounting for 41.2 % of the variance between groups (Fig. 6 A). In turn, LDA analysis shows a clear separation of specimens corresponding to Rineloricaria giua (Fig. 6 B), indicating that morphometric variables used in this study allow morphometric recognition of this species. Contrarily, R. atratoensis overlaps with R. magdalenae. The first two LDA axes explain 79.7 % of the variance (Fig. 6 B), and the overall precision of the classification in the correct group was 75.3 %. Variables with higher scores on the positive LD 1 axis were postanal length, orbital diameter with notch, and abdominal length, while those on the negative side were mouth length, pectoral-spine length, and interorbital width. Higher positive scores for LD 2 were accounted by abdominal length, interorbital width, and orbital diameter with notch; and for the negative axis, postanal length, dorsal-spine length, dorsal-fin base length, and internare width. found to be different from R. magdalenae in morphometric analyses (see above), was recovered as sister to a clade comprising R. altipinnis, R. jubata, R. rupestris, and R. uracantha (node support: 72 %). Genetic distances. — Distribution of paired genetic distances of sequences from the trans-Andean species in our analysis shows a variation range between 3.1 % and 15.9 %. The minimum interspecific genetic distance value found for R. atratoensis and R. magdalenae was 3.1 %, while the maximum scores recorded between R. atratoensis and remaining species were 14.1 – 15.9 %. For R. giua, genetic distances varied from 10.3 % to 15.1 % (Table 2). Delimitation analyses. — Both ASAP and PTP analysis yielded the same 11 putative species, eight of them from the trans-Andean region (Fig. 7). In the ASAP analysis, the second partition was selected, since it agrees with our morphology-based species delimitation (score ¼ 5.00). In the PTP analysis, support values for trans-Andean species were below 50 %, except for Rineloricaria giua, which was 86.7 % (Fig. 7).	en	Castellanos-Mejía, María Camila, Londoño-Burbano, Alejandro, Ochoa, Luz E., García-Alzate, Carlos A., DoNascimiento, Carlos (2024): Two New Species of Rineloricaria (Siluriformes: Loricariidae) from Trans-Andean Rivers of Colombia, Unveiled through Iterative Taxonomy.
