GAONA-ESCAMILLA, Lizbeth; FRANCKE, Oscar F.  e  PONCE-SAAVEDRA, Javier. The genus Krusa (Opiliones: Sclerosomatidae: Gagrellinae) in Mexico. Rev. Mex. Biodiv. [online]. 2016, vol.87, n.4, pp.1235-1256. ISSN 2007-8706.  https://doi.org/10.1016/j.rmb.2016.10.007.

Taxonomic revision of genus Krusa Goodnight and Goodnight,1947 is presented, which currently includes 6 species endemic to Mexico. As K. annulata Goodnight and Goodnight, 1945, K. flava Goodnight and Goodnight, 1946, K. metallica Goodnight and Goodnight, 1946, K. stellata Goodnight and Goodnight, 1947 and K. tuberculata Goodnight and Goodnight, 1946 were described prior to the publication of the description of the genus and the type species, K. mexicana Goodnight and Goodnight, 1947, the use of the generic name must be considered as nomen nudum according to the International Code of Zoological Nomenclature; however, the specific names are valid even if published in combination with a generic name that is not valid or unavailable (International Code of Zoological Nomenclature, Art. 11), and thus they retain the authorship and respective dates of publication. The aforementioned species are redescribed, and K. hidalguensis sp. nov. is described. Krusa flava and K. metallica remain as nominal species and do not belong in the genus Krusa. The genus is diagnosed based on external and male and female genital characters. Our results are congruent with previous molecular studies. A dichotomous key for the identification of species of Krusa is included. The revision leads us to resurrect the genus Krusella Roewer, 1953 from Venezuela.
