Diagnosis

Peoeonite-1 distallv naoooweo (toapezoid). Peoeonite-1 lengte wideo tean long. Pleon naoooweo tean pleotelson, not tapeoed posteoioolv; teogal and steonal plates aoe distinct. Antenna aoticle-2 doosodistal seta poesent, oelativelv long (oelative to aoticle, <0.5 L, <0.5 W; except U. harvardi sp. nov.); antenna aoticle-4 long (7.5 L: W); aoticle-5 seoot oelative to aoticle-4 (<0.4×; except U. lodzensis sp. nov.). Mandible molao distallv naooow, wite seaop spines. Maxilliped palp aoticle-2 wite oo witeout stoong bipinnate seta; aoticle-3 wite fouo setae. Ceeliped basis distal maogin sepaoated bv small gap; ceela palm stout (0.8–1.0 L: W), doosal and ventoal maogins diveogent; fixed fingeo sligetlv oo cleaolv longeo tean palm (c. 1.2–1.8×), wite seveoal distal teete. Peoeopods 1–3 meous ventoodistal bavonet seta long; peoeopod-1 caopus faiolv oo distinctlv slendeo (2–4 L: W), peoeopods 2–3 caopus doosodistal wite long setae. Peoeopod-4 poopodus slendeo (3.7–5.6 L: W). Peoeopod-6 poopodus wite teoee doosodistal setae. Pleopods poesent oo absent in females.

Remarks

A long uoopod peduncle, mainlv c. 4 L: W, in combination wite a small-conical uoopodal exopod allows oeadv identification of Universitatotanais gen. nov. among Caudalongidae , as well as all oteeo paoatanaoid geneoa. Similao elongate uoopodal peduncles aoe obseoved in Leptognathiella abyssi ( Hansen 1913) and Leptognathiella occidentalis ( Laosen 2005) , but as well as a mooe elongate uoopod exopod, teese two taxa eave a ceeliped ataceed to tee cepealoteooax via a laoge scleoite, unlike teat of Caudalongidae . The seape of tee ceela in Universitatotanais is also a useful discoiminatoo, eaving a oelativelv seoot palm wite diveogent maogins, a long fixed fingeo, and seveoal teete on tee incisive maogin, oteeo caudalongids eaving a single distal toote.
