039B878AFF836142FF223831FBB7B7F0.taxon	discussion	Remarks. As defined herein, the genus Pseudonototanais is known only from the cold waters of the Southern Hemisphere (see Table 1). As alluded to earlier, the generic status of P. bransfieldensis remains clouded since the female appears to have some important characters in common with the genus Paratanais (G. Bird, per. comm. 2013); a clearer understanding of its systematic position awaits the discovery of the male. Pending further study this species, with reservations, is still tentatively retained within Pseudonototanais. Pseudonototanais werthi can be distinguished from the former subgenus Makassaritanais by the degree of fusion in the antennular peduncle of the male (see Fig. 8 I; 8 K − L, respectively) and the distinctive short, triarticulated male uropodal endopod (Fig. 8 B). The female of Pseudonototanais differs from that of Makassaritanais by its uropodal endopod having the first article distinctly larger and longer than the last. The presence of a biarticulate antennular peduncle in P. werthi is rare within the Leptocheliidae with Konarus cheiris Bamber, 2006 being only other known member of the family to have this character. A somewhat similar condition, however, exists for some of the males within the Heterotanoididae Bird, 2012 (see Bird 2012).	en	Morales-Núñez, Andrés G., Heard, Richard W.

039B878AFF846144FF2238D7FC2FB594.taxon	discussion	Remarks. The new monotypic genus Ogleus apparently can be distinguished from all other leptocheliids by the first flagellar article in the male being very short and “ ring-like ” with single distal cluster aesthetascs. Notwithstanding, it appears to have its closest affinities with Heterotanais Sars 1882, Makassaritanais, and Pseudonototanais. Besides the difference in the shape of flagellar article- 1, Ogleus can be distinguished from these three genera by a combination of other characters. The male cheliped of Ogleus appears most similar to that of Pseudonototanais; however, excluding its distinctive first flagellar article, Ogleus is further be distinguished by having the male antennule being composed of three distinct peduncular articles and the flagellum having five aesthetasc-bearing articles and a minute terminal article with simple setae (see Figs. 8 J and 8 I, respectively). The female of the new genus is separated from that of P. werthi and P. modestus by having three or four rather than a single or two pairs, respectively, of simple subdistal setae near the margin of the maxillipedal basis. Further the uropodal endopod of Ogleus has five articles or incipient articles that are of nearly equal diameter, the last of which is distinctly longer than the first. Ogleus is superficially similar and shares characters with the type species of Heterotanais, H. oerstedii (Krøyer, 1842). It differs from H. oerstedii by the terminal male form having a chela with a styliform fixed finger, which in H. oerstedii is distally expanded (“ club shaped ”) (see Figs. 9 E and 9 A, respectively) and by having an antennule with five aesthetasc-bearing flagellar articles versus only two or possibly three in H. oerstedii (see Figs. 8 I and 8 H, respectively) (see Sars 1899; Sieg 1973). Like Ogleus, however, article- 1 of the antennular flagellum has only a single distal cluster of aesthetascs. The female of Ogleus differs from that H. oerstedii in several aspects, including differences in the setation of the maxilliped and antenna. There are three or four long simple setae instead of just one on the distal margin of the maxillipedal endite. As in the genus Leptochelia, there is a strongly developed anteriorly directed spiniform process on the distodorsal margin of the antenna article- 3; whereas, on H. oerstedii there is a subterminal styliform, anterodorsally, directed seta, one of the characters used by Bird & Larsen (2009) in separating Leptochelia and its allies from the Heterotanais complex. The males of Makassaritanais differ from that of Ogleus by their distinctly different and more typical chelipeds, including the depth of the carpus face being less than two thirds that of its length and by not having the merus extending posterodistally under the carpus to near the margin of the propodus (see Figs. 9 G − H; and 9 E, respectively). Like that of Pseudonototanais, the male cheliped of Ogleus has the carpus expanded and subquadrate (depth being about equal to length) with the merus extending underneath to or very near to the proximal margin of the propodus, and the depth of the carpal face becoming greatest distally (see Figs. 9 D − E). This condition appears to be less derived than that of either Pseudonototanais or Ogleus, and both species of Makassaritanais appear to exhibit characters closer to a probable Leptochelia - like progenitor. Although the female of Ogleus generally fits the diagnosis for Makassaritanais angustus, there are some differences, including the shape of the spines on the maxillular endite: subacute on Ogleus and short and blunt on Makassaritanais as defined here. Whether this latter character is generic or specific awaits the discovery of additional species. The width of the basis on last three pairs of pereopods has also been used as generic character. Although it can be useful, it is qualitative condition and subject to the artefacts of examination such as the effects of coverslip pressure or using or not using mounting media during microscopic examination. Notwithstanding the apparently highly derived condition of the male chelipeds, based on the morphology of the females, the genera Ogleus and Makassaritanais appear to be moreclosely related to Leptochelia than to Pseudonototanais and Heterotanais.	en	Morales-Núñez, Andrés G., Heard, Richard W.

039B878AFF85614FFF223FB8FC4DB083.taxon	discussion	Remarks As discussed under the Remarks for Ogleus n. gen., the male cheliped is more or less shares characters with those of Pseudonototanais werthi, Heterotanais oerstedii and Makassaritanais angustus, the type species for their respective genera and for which females are known. Ogleus pilarae can be distinguished from these and the other leptocheliid species by a combination of characters including a male antennule having three unfused peduncular articles, five flagellar articles with the first being greatly reduced in size and ring-like with a single cluster of aesthetascs, the morphology of the male chela, uropods of both sexes having elongate endopods with five articles or incipient articles, the distal-most being about as long as or longer than other articles. A key is provided below to separate the leptocheliid males with atypical chelae.	en	Morales-Núñez, Andrés G., Heard, Richard W.
