Becker (MCNZ 15170).
Diagnosis. Females of E. caudatus are very similar to those of E. pustulosus in the cryptic bark-dweller habitus with predominant dark-brown body coloration, squared leg segments and knobby femora, however, they can be distinguished at first sight by the presence of vivid orange/reddish blister-shaped setae sockets on the ventral surface of their anterior femora (Fig. 15C), while in females of E. pustulosus these structures are yellow (Fig. 15E). Females of E. caudatus also present a large median septum on the epigynal plate separating the exposed copulatory openings. Males can be recognized by the half-moon shaped stains on the dorsum of the opisthosoma, wide and stout opisthosomal projections and by the DTA pointing upwards.

Diagnosis. Females of E. rubripes are similar to those of E. heterogaster in their stout and vertically oriented MS and in the projections above the ALE. However, they can be recognized by their “mask” pattern, which is composed of a pair of vertical dark lines on the AME and a pair of diagonal ones going from ALE to the lateral margin of the clypeus, merging to form an entire dark clypeal margin (Fig. 16C). They can also be distinguished from other species of the genus by their median posterior opisthosomal projection, which is much thicker and longer than the four lateral projections (Fig. 16C). The males present vertical projections above the ALE as in E. heterogaster, however, their opisthosoma has only three projections and the same color pattern as in the males of E. taczanowskii and E. trituberculatus (see Silva-Moreira & Machado 2016: figs 9A–E). Their unique palp is characterized by the embolous emerging form tegulum at nine o’clock position and by RTA short and wide and DTA pointing to the apex of the cymbium (see Silva-Moreira & Machado 2016: figs 10A–E, 15I).

description: Die ins Deutsche übersetzte Version des ODQ misst das Erleben der Rückenschmerzen und die Einschränkungen im beruflichen, privaten und sozialen täglichen Leben eines Patienten. Er ist in 11 Abschnitte untergliedert, die jeweils einen Aspekt der Schmerzen zum Thema haben: (1) Dauer der Schmerzen, (2) Ausmaß der Schmerzen/Schmerzstärke, (3) Persönliche Versorgung, (4) Heben und Tragen, (5) Gehen, (6) Sitzen, (7) Stehen, (8) Schlafen, (9) Sexualität, (10) Soziale Kontakte, Teilhabe am sozialen Leben und (11) Reisen. Der erste Abschnitt "Dauer der Schmerzen" fließt jedoch nicht in die Itemauswertung mit ein, sondern es soll lediglich jeweils für Rücken- und Beinschmerzen angegeben werden, seit wie vielen Jahren, Monaten und Wochen der Patient bereits darunter leidet. Somit besteht der ODQ aus 10 Items mit jeweils sechs Stellungnahmen. Die Stellungnahmen sind in aufsteigender Reihenfolge der Beeinflussung durch den Schmerz auf diesen Bereich sortiert. Reliabilität: Als interne Konsistenz wurde ein Cronbachs Alpha = .94 für den Gesamtfragebogen berechnet. Validität: Die Ergebnisse einer sehr ähnlichen Übersetzung des Oswestry Low Back Pain Disability Questionnaire von Osthus et al. (2006) sprechen trotz der geringfügigen Unterschiede in der Übersetzung für die Konstruktvalidität, Änderungssensitivität und Reliabilität des Verfahrens.
description: The ODQ, which is translated into German, measures the experience of back pain and the limitations in the professional, private and social daily life of a patient. It is divided into 11 sections, each of which deals with one aspect of pain: (1) Duration of pain, (2) Extent of pain/pain intensity, (3) Personal care, (4) Lifting and carrying, (5) Walking, (6) Sitting, (7) Standing, (8) Sleeping, (9) Sexuality, (10) Social contacts, participation in social life and (11) Travel. The first section "Duration of pain" is not included in the item evaluation, however, but should only be given for back and leg pain, for how many years, months and weeks the patient has been suffering from it. Thus, the ODQ consists of 10 items with six statements each. The statements are sorted in ascending order of the influence of pain on this area. Reliability: A Cronbach's Alpha = .94 was calculated as internal consistency for the overall questionnaire. Validity: The results of a very similar translation of the Oswestry Low Back Pain Disability Questionnaire by Osthus et al. (2006) speak for the construct validity, change sensitivity and reliability of the measure despite slight differences due to translation.

Remarks. At the time of writing, 36 species have been described in the Family Agathotanaidae, distributed in the four genera Agathotanais Hansen, 1913, Paragathotanais Lang, 1971, Metagathotanais Bird & Holdich, 1988, and Paranarthrura Hansen, 1913. The enigmatic Paranarthrurella Lang, 1971, considered to be very doubtfully placed in the Agathotanaidae by Bird & Holdich (1989), has recently been revised and unambiguously removed from the family, albeit placed with an incertae sedis category (Jóżwiak et al 2009). A recent paper on agathotanaids from Japanese waters by Larsen (2007) usefully summarised taxonomic changes and issues up to that date. Phylogenetic analyses are undoubtedly required to interrogate possible paraphyletic genera such as Paranarthrura but are beyond the scope of this paper. These may be linked to ongoing studies following Bird & Larsen (2009).
A remaining taxonomic issue is the structure of the cheliped-cephalothorax articulation, i.e. whether it is formed from a ‘sclerite’ or 'pseudocoxa' (see Larsen 2007). It is evident that the cheliped in all agathotanaids is attached to the cephalothorax via a sclerite, with the cheliped basis lacking any posterior free process (c.f. Tanaidae, Leptocheliidae and Paratanaidae, etc.). This arrangement is variable, with some taxa having discrete and protuberant sclerites (e.g. Paranarthrura insignis, Bird & Holdich 1989, fig 1j) and others with fused sclerites, with or without a gap between the cheliped bases (Agathotanais ingolfi, Bird & Holdich 1988, fig 2g and Metagathotanais insulcatus, Bird & Holdich 1988, fig 2k). Phylogenetic analysis of these and other cheliped-cephalothorax morphologies is ongoing.
Morphometric data and the inferred life-history patterns suggest that, at least for Agathotanais ingolfi, Paragathotanais robustus, P. nanus and Paranarthrura insignis, two male phases exist: a (smaller) primary male developing directly through several (indeterminate) moults from the manca/juvenile and a (larger) secondary male developing from a female—i.e. sequential hermaphroditism.

Distribution records from the AFEN, BIOFAR & BIOICE surveys. Recorded in nine AFEN samples from the Ymir Ridge, Hebrides Slope, Barra Fan, and North Rockall Trough, at depths 1312–2046 m; five samples from the BIOFAR survey, from the Lousy Bank, Iceland-Faroe Rise [South], and Iceland Basin, at depths 597–1157 m; 53 BIOICE samples, from the Denmark Strait, Iceland Basin, Iceland-Faroe Rise [South], Irminger Basin, and Reykjanes Ridge, at depths 497–2177 m. The highest abundance (sample count) was 677 specimens in BIOICE sample 2337 from the Iceland Basin, at 1099 m.
Distribution elsewhere. From North Feni Ridge to the South Biscay Slope, 1160–2890 m (Bird & Holdich 1988). Also recorded from the Georges Bank (North-West Atlantic) at 2257–3236 m (Larsen 1999a); Denmark and Davis Straits at 1441–2193 m (Hansen 1913), and the North Sea off Northumberland (NE England) at <200 m (Bamber 1986).
Remarks. As with the previous study (Bird & Holdich 1988), in some samples this agathotanaid has proved to be one of the most abundant tanaidaceans, particularly those from the Iceland Basin. The new records also confirm that A. ingolfi is excluded from the ‘cold-water’ zone North of Iceland, the Faroes and the Wyville-Thomson Ridge (Fig. 1), and it is found where benthic temperatures average between 2o to 6.5o C (mode 4o C).

Remarks. As with the previous genus, Paragathotanais is a eurybathic and cosmopolitan taxon. Confusion about the number of antennal articles has arisen following the diagnosis of Paragathotanais given in Bird & Holdich (1988) and the comments offered by Larsen (2007). Bird & Holdich defined the antenna of the relevant taxa as being six-articled, rather than five-articled as used by Larsen. This apparent conflict arises because the most basal article (article-1) is small and effectively fused to the cephalothorax. In order to preserve the homogeny of the antennal articles in descriptions and comparisons the Bird & Holdich terminology is used here, even though the detached/separated antenna has the appearance of being five-articled.

Identification reference. Bird & Holdich (1988).
Distribution records from the AFEN, BIOFAR & BIOICE surveys. Recorded from four AFEN samples, from the Ymir Ridge, Wyville-Thomson Ridge, and North Rockall Trough, at depths 797–1886 m; four BIOFAR stations, from the Iceland-Faroe Rise and Iceland Basin, at depths 430–1038 m; 47 BIOICE stations, from the Denmark Strait, Iceland Basin, Irminger Basin, and Reykjanes Ridge, at depths 230–2082 m. The highest count was 145 specimens from BIOICE sample 2268, Irminger Basin, at 450 m.
Distribution elsewhere. From North Feni Ridge to the South Biscay Slope, 1160–2227 m (Bird & Holdich 1988).
Remarks. With regard to pereonite shape (Fig. 2 A), this new material of Paragathotanais nanus shows this character to be more variable than described and illustrated in Bird & Holdich (1988) and some individuals have distinct ‘shoulders’ or weak processes above the pereopod insertion (Fig. 2 B). These are more similar to the more angular males in this respect and discrimination of P. n a n u s from the sympatric P. robustus is slightly more difficult. The body shape of the more angular individuals is actually very similar to that of P. s p i n o s u s from the Gulf of Mexico (Larsen 2005) but no other difference in morphology between the angular and normal forms of P. n a n u s could be found (e.g. Figs 2 C–D). It is quite possible that these are a moult stage on the developmental path towards becoming a secondary male, with very early preparatory males having a very narrow pleon with barely-visible rudimentary pleopod ‘buds’.
This species has proved to be common and occasionally abundant in the Iceland-Irminger basins, where mean benthic temperatures are between 2–8o C (mode 4o C). The upper bathymetric limit of distribution records has been considerably raised, from 1160 m (see above) to 230 m.

Distribution records from the AFEN, BIOFAR & BIOICE surveys. Recorded from 22 BIOICE stations, from the Denmark Strait, Iceland Basin, and Irminger Basin, at depths 256–1533 m. Not recorded in the AFEN and BIOFAR material. The highest count was 123 specimens from BIOICE sample 2475, Iceland Basin, at 842 m.
Distribution elsewhere. From North Feni Ridge to the South Biscay Slope, at depths 1279–2246 m (Bird & Holdich 1988).
Remarks. Care is needed to distinguish this species from P. nanus when they co-occur in samples (see above) but the broader pleon and more pointed pleotelson are diagnostic characters (Fig. 2 E). As with the previous two agathotanaid species, the recorded upper bathymetric limit of P. robustus is now much shallower, raised from 1279 m (see above) to 256 m. A similar range of benthic temperatures of 2–4o C is also evident.

description: Paranarthrura Hansen, 1913
Hansen (1913): 121–122.
Lang (1971b): 367–368.
Bird & Holdich (1989): 139, 143. Larsen (2005): 120–121, 138, 140. Larsen (2007): 54.
Remarks. This genus remains somewhat heterogeneous (Bird & Holdich, 1989; Larsen 2007) and possibly polyphyletic, particularly with regard to smaller species such as P. borealis and P. subtilis (see below). This issue is probably best interrogated within a phylogenetic review of possibly related, or apparently convergent, taxa such as Allodaposia Sieg, 1986, Arthrura Kudinova-Pasternak, 1966, Caudalonga Larsen, 2005, Libanius Lang, 1971, Macrinella Lang, 1971 and Pseudoarthrura Larsen, 2005.

Paranarthrura borealis

description: Paranarthrura borealis Bird & Holdich, 1989
Bird & Holdich (1989): 158–159; figs 1e, 10–11. Guerrero-Kommritz et al (2002): 10. Guerrero-Kommritz (2003): 3
Larsen (2006): 121, 140.
Identification reference. Bird & Holdich (1989).
Distribution records from the AFEN, BIOFAR & BIOICE surveys. Recorded from only three BIOICE stations in the Iceland Basin at depths 1070–1780 m.
Distribution elsewhere. From North Feni Ridge around to the Malin Slope, 903–1600 m (Bird & Holdich 1988).
Remarks. This additional material of Paranarthrura borealis supplements the original description with respect to body length: neuters/non-ovigerous females were measured at 1.4–2.02 mm (max length 1.80 mm in Bird & Holdich 1989) with males from 1.45–1.56 mm (1.6 mm in original study).
Considered to be rare in the Rockall-Biscay area (Bird & Holdich 1989), this small species is restricted to the southern part of the BIOICE area. It has been recorded in the AFEN study area but only from the earlier SMBA surveys (Bird & Holdich 1989; Bird 2001). Benthic temperatures of 4o C were associated with sample localities for this species, and the recorded lower bathymetric limit has deepened slightly from 1600 m to 1780 m. It could be under-collected because of its small size and narrow body shape.
