Abstract
A taxonomic revision of Sturisomatichthys is presented. A total of 383 specimens including both type and non-type specimens of all valid species were examined. Sturisomatichthys was found to encompass ten valid species: Sturisomatichthys aureus, S. caquetae, S. citurensis, S. dariensis, S. festivus, S. frenatus, S. kneri, S. leightoni, S. panamensis, and S. tamanae. In addition, three new species are described: Sturisomatichthys reinae, new species, from the Baudó River, in northwestern Colombia, belonging to the Caribbean slope of the continent; Sturisomatichthys guaitipan, new species, from the upper and middle Magdalena River basin, Colombia; and Sturisomatichthys varii, new species, from the San Juan River basin in western Colombia, on the Pacific slope. Sturisomatichthys caquetae, from the Morelia River, upper Amazon, is transferred back from Sturisoma, and S. leightoni was found to be distributed, besides the Magdalena-Cauca basin, in the Orinoco basin; thus, Sturisomatichthys is shown to be distributed in both trans- and cis-Andean drainages. A neotype is designated for S. aureus from the lower Magdalena basin. New records of localities in the northwestern region of South America, as well as the redescription and taxonomic comments on all valid species, are provided. Maps with the species distributions and a key for identification of the species are provided.

Sturisomatichthys reinae, new species
Etymology.—The specific name honors Mrs. Ruth Gisela
Reina, late curator of fishes at STRI, for her contributions to
the knowledge of fishes and invaluable help and assistance
for several ichthyologists around the world during her time
at the STRI.

Sturisomatichthys guaitipan, new species
Etymology.—The specific epithet guaitipan honors Gaitana,
an indigenous heroine from the 16th century, cacique of the
Timaná tribe, who occupied the Colombian Andes in the
upper Magdalena valley in the Meta department. Gaitana, or
Guaitipan as she was also known, fought against the Spanish
invasion that occurred in South America between 1539 and
1540, ending in her defeat due to treason by the cacique
Matambo, who warned the Spanish army of the rebellion led by Gaitana. Finally in 1626, joining forces with the Pijaos,
Panaes, and Pamaos, they obtained victory by expelling the
Spanish from their region.
Sturisomatichthys varii, new species
Etymology.—The specific name honors Richard P. Vari for his
important and numerous contributions to the knowledge of
Neotropical fishes, and for his interest in helping young
ichthyologists pursue careers in science to continue to
explore the diversity of such Neotropical fishes. Richard left
an important legacy which, with no doubt, will help present
and future ichthyologists in their research. The conclusion of
this study would not have being possible without the selfless
and extensive help received from Richard.
