Exopod article 1 with one medial seta.</p><p>Remarks. The new species is unique in having a terminal ‘curled leaf-shaped’ seta on the pereopods 2 to 6. Only one other species, L. wolffi (Lang, 1968), is recorded with terminal unguis setae on pereopods 2 to 6. However, in that species, the pereopod 4 dactylus/unguis is reduced to a claw and the unguis setae are not really leafshaped but appear simple (Lang 1968:115,fig. 64c.1), although they are described as “ claw…. bifid at the tip” (Lang 1968:116).</p><p>Four other members of the genus are recorded from the east Atlantic: L. leptodactylus; L. segonzaci segonzaci Bäcescu, 1981; L. zenkevitchioides Bäcescu, 1981; L. caecus (Willemoes-Suhm, 1875) . Leviapseudes segonzaci segonzaci and L. zenkevitchioides can both be separated from the new species by the pereopod 4 dactylus/unguis being reduced to a claw and L. segonzaci segonzaci additionally by having many setae on the basal article of the uropod. Leviapseudes leptodactylus was originally described by Beddard (1886) from the ‘North Atlantic’ and then supplementary redescribed by Lang (1968), also from the “North Atlantic, Siboga st. 78” (Lang 1968:193). However, something must be wrong here, as the Siboga station 78 was taken off the coast off Borneo. Unfortunately both these descriptions are incomplete and diverge on a number of characters, making comparison difficult. Leviapseudes macaronesia can be separated from L. leptodactylus sensu Lang, 1968 by being: 1) the presence of pereopods dactyli leaf-shaped setae; 2) being twice as long relative to width as L. leptodactylus; 3) having a pereopod 1 carpus and propodus of similar length. Differences from L. leptodactylus sensu Beddard, 1886 include pereopod 1 missing proximal spines, having a carpus and propodus of similar length and serration on the dactylus. Also the pereopods dactyli leaf-shaped setae seem to be missing in Beddard’s (1886) description. Leviapseudes caecus is also a problematic species to compare with. The original description by Willemoes-Suhm (1875) is unusable for modern taxonomic comparisons. Furthermore, the type material is lost (Sieg 1983:93) and the same author lists this species as belonging to genus Apseudes Leach, 1814 . A year later this species appear in a key to Leviapseudes (Bäcescu 1984:34) and is attributed to Willemoes-Suhm, 1874 rather than 1875. Bäcescu’s (1984) key relies heavily on the presences and size of hypospherians, a character notorious unreliable (Lang 1953), but apparently suggest that the female L. caecus have the pereopod 4 dactylus/unguis reduced to a claw (couplet 6–7) and also differs from the new species in having more articles in the inner rami of the antennule (couplet 34–35).</p><p>From all other species of the genus L. macaronesia can, apart from the pereopods 2–6 unguis apical curledleaf-shaped setae, be separated by the combination of: 1) cheliped carpus longer than basis and dactylus longer than fixed finger; 2) pereopod 4 dactylus/unguis not reduced to a claw; 3) pereopod 1 merus almost as long as basis.</p><p>Several appendages had ciliates attached to the cuticle (Fig. 2 J) as also seen in other deep-sea tanaids (Larsen 2006).</p><p>Family Sphyrapodidae Gu ț u, 1980</p><p>Subfamily Pseudosphyrapodidae Gu ț u, 1980</p><p>Type genus. Pseudosphyrapus Guţu, 1980 Genus Pseudosphyrapus Gu ț u, 1980</p><p>Diagnosis (Modified after Guţu 1980, 1991, and Larsen 2005). Antennule with bi- or tri-articulate inner ramus. Antenna without squama/pseudosquama. Mandible with tri-articulate palp.</p><p>Male. Antennule with dense rows of aesthetascs. Maxilliped endite with distal outer corners ornamented. Pereopod 1 is longer and thinner than in the female and endite setation is different, in particular less setose than that of female. Cheliped dactylus with inner process. Merus and carpus longer than those of female. Pleopods with twice as many setae as in female.</p><p>Type species. Sphyrapus serratus G. O. Sars, 1882 .</p><p>Remarks. The character of the complete absence of a pseudosquama is stable in this genus. The presence of a tri-articulate mandibular palp is shared with Kudinopasternakia .</p></div>	https://treatment.plazi.org/id/03D387C1FFB1256386B7FE6CFCC6E525	Public Domain	No known copyright restrictions apply.

This species is unique within this genus in only having mandibular palp setae on article 3.</p><p>The spine-like structures on the proximal part of the maxilliped deserves serious attention. These structures are only reported from the family Sphyrapodidae, but not in all species and not correlated with specific genera. These ‘spines’ are observed in the new species and also found in Pseudosphyrapus siegi (Viskup &amp; Heard 1989), P. c u s - pidiger (Kaukui et al. 2007), P. centobi (Bäcescu 1981) and P. quintolongus (Kakui et al. 2007) (but only from the female) and are not reported from the other species of the genus. However, this may be an observational mistake as this character is reported from a number of other sphyrapodids: Kudinopasternakia balanorostrata (Kauku et al. 2007), K. brasiliensis (Santos 2007), K. trispinosa (Santos 2007), K. dispar (Lang 1968), and something that could be interpreted as such spines are illustrated on Sphyrapoides tuberculifrons (Guțu &amp; Heard 2002). The main problem with these structures seem to be their exact location about which there is little consensus. Kakui &amp; Kajihara (2011:57, fig 3B) reports them as origin from the coxa and so does Viskup &amp; Heard (1989:110) although their illustration (Viskup &amp; Heard 1989:112, fig.4C) suggest they arise from both the coxa and basis. Others report them from both the coxa and basis (Bäcescu 1981, Kaukui et al. 2007) but the later authors also states concern about their true origin (Kaukui et al. 2007:40). This author is convinced that these structures arise from a thin membranous flap covering the proximal part of the maxilliped, partly covering both the basis and coxa making observation of this character difficult.</p></div>	https://treatment.plazi.org/id/03D387C1FFB6256E86B7FA3CFE14E37B	Public Domain	No known copyright restrictions apply.

Exopod uniarticulated with one medial seta, one simple distal seta, and one seta longer than endopod.</p><p>Remarks. This species is in most respects similar to P. martinsi (Bamber &amp; Costa, 2009), also found at the Azores, albeit at the much more shallow depths of 37.8 meters (Bamber &amp; Costa 2009). The major differences are the large process on the inner side of the cheliped fixed finger and the propodus with one pointed and one blunt, wide, flat, outer distal setae near dactylus insertion; all pereopods with only one ischial seta. More subtle differences are: the larger spiniform seta on the antenna article 3; the proportionally longer pereonite 1, about half as long as carapace and two-thirds as long as pereonite 2 (while about 40% of carapace length and 56% of pereonite 2 length in P. martinsi); The longer pleotelson, about 35% the total length of pleon (while less than 20% in P. m a rtinsi); the dorsal serration/spines on the dactylus of pereopod 5 &amp; 6. It is still possible that these are only morphological variations associated with depth, but only a genetic analysis can confirm/reject this. Furthermore the genus Paratanais is infamous for its many cryptic species (Larsen 2011). Therefore I have chosen to erect a new species but with a name reflecting the close similarity with P. martinsi .</p></div>	https://treatment.plazi.org/id/03D387C1FFBC256A86B7FF56FCF8E3EF	Public Domain	No known copyright restrictions apply.
