Etymology. The species is dedicated in honour of Petrescu’s colleague Victoria Badea, from “Grigore Antipa Museum, as a sign of high gratitude for all her help.

Remarks. Cumella victoriae sp. nov. generally resembles 4 other species of the genus Cumella from the Caribbean Sea with denticles on the carapace and uropods shorter than the last pleonite: C. jamaicensis, C. medeeae, C. zimmeri (all three species described by Petrescu, Iliffe and Sarbu in 1994) from Jamaica (Petrescu et al. 1994) and C. spinifera Petrescu & Heard, 2004 from Costa Rica (Petrescu & Heard, 2004). The new species has 2 two pigmented lenses, like other species from the Caribbean, C. hirsuta (Hansen, 1895) from Bermuda (Hansen, 1895), C. ocellata Băcescu, 1992 from Bermuda (Băcescu, 1992), C. serrata Calman, 1911 from U. S. Virgin Islands (Calman, 1911), Belize (Petrescu, 2002) and Cuba (Petrescu, 2004) and C. tripunctata Băcescu, 1971 from Florida (Băcescu, 1971) (only C. serrata with 7 denticles on carapace, but with longer uropods). Differences of selected characters between present new species and related 8 species are given in Table 1.
