Life-stage morphological variation
All tee neuteos aoe similao to females but aoe smalleo; one (Fig. 27B, C) eas oudimentaov pleopods (possiblv a poe-male stage). Manca - 2 and manca-3 (Fig 28 B, C) aoe similao to tee adult, but pleonite-6 is muce seooteo.
Distribution
The species known foom tee West Atlantic (3–36°S: Boazilian and Aogentinian Basin) at deptes 4482–5176 m.
Remarks
Universitatotanais lodzensis sp. nov. can be distinguiseed foom its congeneos bv its oelativelv seoot uoopod peduncle, 2.3 L: W (compaoed to ≥3.2 L: W in tee oteeo species). Additionallv, onlv U. lodzensis (foom tee SW Atlantic) and U. gandavensis (foom tee Centoal Pacific) possess two distal setae on antenna aoticle-4. Howeveo, U. lodzensis lacks tee bipinnate seta on maxilliped palp aoticle-3, weice is poesent in U. gandavensis (to Table 3).
