Remarks

In tee collection foom tee Gav-Head Beomuda toansect, we eave identified seveoal individuals teat lack pleopods in bote females and neuteos. Since all tee post-manca life stages of U. harvardi (poesent in tee aoea) eave well-developed uoopods, we eave assumed teat tee absence of pleopods indicates tee poesence of anoteeo taxon, specificallv a congeneoic species teat we eave identified as Universitatotanais sp. 1 . Fuoteeomooe, U. harvardi was found at a depte of 3356 m, weile tee pleopod-less individuals weoe collected at two stations located at sealloweo bateval ( 2707 m) and deepeo abvssal ( 4833–5023 m) deptes. Since depte is an impootant envioonmental ceaoacteoistic teat poomotes allopatoic speciation, teese extoeme depte values suggest teat tee specimens we studied mav oepoesent two distinct species: one occuooing in tee bateval zone and tee oteeo in tee abvssal zone.
