“…Ghazzi [ 36 ] carried out a morphology-based phylogeny including eight valid species of Sturisoma sensu lato , plus five undescribed species, and found a monophyletic Sturisoma including only cis-Andean species, plus S . kneri (= Sturisomatichthys kneri ), which was found here not to belong to Sturisoma , a conclusion in agreement with those of Covain et al [ 15 ], and Londoño-Burbano and Reis [ 90 ]. Ghazzi [ 36 ] used 20 characters to support that clade [ 36 ]; 12 of which were analyzed here (see [ 36 ] for the list of Synapomorphies, and Character Description).…”

“…Twelve characters found as synapomorphic for Farlowella were tested here, but differences regarding her results were found. One character (her character 124), was indeed found as synapomorphic for the genus, the low number of caudal-fin rays (character 191), also shared by Aposturisoma myriodon and Sturisomatichthys guaitipan [ 90 ].…”

“…caquetae were not included in this study, the holotype of Harttia caquetae (ANSP 71719) was examined and found to have external diagnostic characters of Sturisomatichthys . Thus, Sturisoma caquetae was transferred back to Sturisomatichthys by Londoño-Burbano and Reis [ 90 ]. It is worth noting that S .…”

We present a combined molecular and morphological phylogenetic analysis of the Loricariinae, with emphasis on the Harttiini (Cteniloricaria, Harttia, and Harttiella) and Farlowellini (Aposturisoma, Farlowella, Lamontichthys, Pterosturisoma, Sturisoma, and Sturisomatichthys). Character sampling comprised seven molecular markers (the mitochondrial Cytb, nd2, 12S and 16S, and the nuclear MyH6, RAG1 and RAG2) and 196 morphological characters. A total of 1,059 specimens, and 159 tissue samples were analized, representing 100 species. A Bayesian Inference analysis was performed using the concatenated data matrix, which is comprised of 6,819 characters. The Loricariinae were found to comprise the tribes (Hartiini (Loricariini, Farlowellini)), the latter two elevated from subtribes. A Maximum Parsimony analysis was also performed using the same data matrix in order to reveal phenotypical synapomorphies to diagnose each clade. Two MP trees were found with a length of 14,704 steps, consistency index of 0.29 and retention index of 0.61, which were summarized in a strict consensus tree. Harttiini includes (Harttiella (Cteniloricaria, Harttia), and Farlowellini includes (Lamontichthys (Pterosturisoma (Sturisoma (Sturisomatichthys, Farlowella)))). Aposturisoma was recovered nested within Farlowella and is synonymyzed to the latter. Sturisoma was corroborated as strictly cis-Andean, while Sturisomatichthys encompasses, besides the valid species already included in the genus, the trans-Andean species once belonging to Sturisoma sensu lato. Identification keys and phylogenetic diagnoses of family-group taxa and genera of both the Harttiini and the Farlowellini are provided.

A new loricariin species of Sturisoma is described from the Cautário, Guaporé, Mamoré, Machado and Soteiro rivers, Madeira River basin, in Bolivia and Brazil. The new species is distinguished from its congeners by the presence of a middorsal longitudinal, thin dark brown stripe on the caudal peduncle, extending from two or three plates posterior to the dorsal-fin base, reaching the origin of the caudal fin, or one or two plates anterior to the origin of the caudal fin; small squarish anteriormost abdominal plates; and a middorsal longitudinal dark-brown stripe from first predorsal plate to near the dorsal-fin origin. Furthermore, the new species is diagnosed from congeners by plate morphology, counts on the median series, coalescent plates and ventrolateral thoracic plates, in addition to measurements related to body and head structures. An analysis of genetic distances using cytochrome C oxidase subunit 1 gene marker of the mitochondrial genome between the new species and several congeners is presented, in addition to a likelihood analysis to illustrate the position of the new taxon within Sturisoma. An identification key for species of the genus currently recorded at the upper Amazonas River basin is provided.
