            <p>Description. Cephalothorax with broad rostrum tapering slightly distally into sloping broad frons, rostrum broader and longer than antennula article 1, labrum about twice as long and much narrower than clypeus. Antennula of male visibly more stout than of female. Antennula article 1 tapering distally, without distomedial lobe. Pereonite 1 subequal to cephalothorax in length behind antennula insertion, pereonites 2–4 slightly broader than pereonite 1, laterally almost twice as long as pereonite 1. Pereonite 5 tergum has broadly rounded elevations with an angular keel in middle of each diametric half of the segment anterior to pereonite 6; pereonites 5 and 6 lateral length subequal, pereonite 6 longest medially, pereonite 7 shortest, subequal to anterior pereonites. Venter of natasomal pereonites protruded medially, pereonite 6 with largest ventral protrusion. Pleotelson about one third of body length, inflated, posterolateral margin slightly curved ventrally with flexion for uropod insertion, anus separated from pleopodal cavity by weakly pronounced preanal ridge. Opercular pleopods in both sexes covering anus, almost as long as pleotelson, ventrally inflated to same degree as pleotelson dorsally. Mandibular palp slender, length 0.8 mandibular body length, distal article elongate, reduced; molar tapering to distal spinose margin, condyle shorter than molar. Maxilliped palp article 1 with small acute distolateral projection, article 2 with long acute distolateral projection; article 3 distomedial margin projected distally, rectangular; article 4 distomedial lobe well produced; epipod elongate, subequal to basis in length, of roughly rhomboid shape, distal margin narrowly peaked. Pereopod 1 smallest, less than body length (0.55–0.8), slender, with scattered small simple setae, carpus broadest proximally, subequal in length to propodus and dactylus together. Pereopods 2–4 increase in elongation from pereopod 2 to 4, pereopod 2 subequal to body length; pereopod 4 about twice as long as body.

            <p> Remarks. With regard to the small size, the general habitus, the large (broad and long) rostrum and the antennula article 1 without a distomedial lobe  Tytthocope resembles  Baeonectes ,  Belonectes and some species of  Disconectes . However, it differs from these similarly small eurycopines by the separated natasomal pereonites, the short pereonite 7 and the inflated pleotelson. Species of the three genera mentioned have fused pereonites 5 and 6, a pereonite 7 which is comparable to pereonites 5 and 6 in length and a somewhat flattened pleotelsoon.  Tytthocope is the only genus of the subfamily with a greatly reduced pereonite 7. This character of  Tytthocope resembles that of the genus  Coperonus , a member of the subfamily  Lipomerinae Tattersall, 1905 which is characterized by a reduced or absent pereonite 7. The pereopod 7 of  Tytthocope is reduced only in size like in  Disconectes ,  Baeonectes and  Belonectes (to a larger degree), but not in swimming morphology as in  Coperonus .  Tytthocope also shares with  Coperonus and some species of  Lionectes and  Mimocopelates (Lipomerinae) a special structure of the natasome tergum, the dorsal surface of pereonite 5 in front of the suture with pereonite 6 has a pair of the broadly rounded elevations with an angular keel, therefore the suture between pereonites 5 and 6 looks compressed. Wilson &amp; Hessler (1981: 411) already noted in their generic remarks that “highly convoluted branchial pleopods of  Tytthocope megalura , are unusual among the genera of the  Eurycopinae . This pleopod form may be characteristic of the genus. However, pleopods III–V are known in too few species.” Our study of the four other species of  Tytthocope revealed the same structure of the pleopods that confirmed this assumption. We suggest that together with the size ratios of rostrum to antennula article 1 and pereonites 5–7 to pleotelson lengths, the ventral protrusion of pereonite 6 and the special characters of the pleopods, as well as those of the maxilliped may be distinguishing for the genus. Though all eurycopines have a somewhat expanded lateral margin of maxilliped palp article 2, only  Tytthocope species have a projected acute distolateral margin on it. All studied species of  Tytthocope possess a laterally expanded article 2 with the projected acute distolateral margin, an article 3 which is noticeably narrower than article 2, with produced rectangular distomedial margin, a relatively narrow distomedial lobe of article 4 (comparing with broad lobe in  Belonectes ) and an elongate epipod. These characters (Fig. 31) are useful interspecific diagnostic characters. The five known species of  Tytthocope have been collected from depths of less than 1461 m, therefore the records for the new species are the deepest (Table 1), though Wilson and Hessler (1981) mentioned three undescribed species from the Atlantic deep sea. </p>

            <p> Remarks. In possessing denticles on the rostral margins, and with regard to the short pereonite 7, the new species resembles the type species of the genus,  T. megalura . The maxillipeds of both species have a similar shape: palp article 2 has a long distolateral projection, article 3 is visibly narrower than article 2: its width is just 0.8 of article 2 width. The differences to  T. megalura are: medial margin of article 3 is serrate in the new species and smooth in  T. megalura , article 5 is more slender than that of the latter, the endite of the new species has 5 coupling hooks instead of 3 in  T. megalura . In contrast to  T. megalura the male pleopod 1of the new species has a broader distal margin with acute lateral projections; the male pleopod 2 has a longer, more slender stylet, the exopod of pleopod 4 has 2 distal plumose setae instead of 1 in  T. megalura . </p>
            <p> The following new species described herein also belongs to this group of species. When Wilson &amp; Hessler (1981) redescribed  T. megalura they mentioned three undescribed species from the Atlantic deep sea with a similar serrate rostrum, but these species are still undescribed. </p>
            <p>Distribution. The Weddell Sea, at depths between 1584 and 3894m.</p>

            <p> Remarks.  Tytthocope longitelson sp. nov. ,  T. megalura and  T. fahrbachi sp. nov. are closely related. These all have a serrate rostral margin and a short pereonite 7.  T. longitelson sp. nov. differs from the above mentioned two species due to the shape of its rostrum, which has a broad base and a relatively small article 1of the antennula. The new species is also different because of its short pereonite 5, which is as long as the ambulosomites, as well as its extremely short pereonite 7. The pleotelson of the new species is broader and longer than in the other species and has an acute posterior tip (compare Fig. 30), a raised anteromedial margin of the pereonite 5 and the pleotelson. The maxilliped of the new species has an intermediate shape (compared to the two other species): article 3 has a more rounded distomedial margin, the medial margin of article 3 is less serrate in the new species compared to  T. fahrbachi sp. nov. , and the distomedial lobe of article 4 is longer than in the other two species. It has 3 coupling hooks like in  T. megalura instead of 5 in  T. fahrbachi sp. nov.</p>

            <p> Remarks.  T. divae sp. nov. is similar to  T. sulcifrons in having a rounded rostrum lacking the serrate lateral keels. Pereonite 7 of both species is relatively long in comparison to that of the  T. megalura group of species. The differences of the new species from  T. sulcifrons are the following: pleopod 1 of  T. divae sp. nov. has almost parallel sides in contrast to the tapering pleopod 1 of  T. sulcifrons ; the medial lobe of article 4 of the maxillipedal palp is subequal in length and width to article 5, the lobe in  T. sulcifrons is longer and thicker than article 5. </p>
