On the basis of the females Bradford (1971) concluded that the only difference between Snelliaetideus Vervoort, 1949 and Aetidius Brady, 1883 was the absence of postero-lateral thoracic points. According to Roe (1975, p.305) the discovery of A. arcuatus male confirms Bradford’s opinion and SnelliaetideusAetideus. |

The bathymetric distribution of these forms shows generally a very wide amplitude.
For Tanaka (1957, p/176) the genus is characterized by the head usually separates from 1st thoracic segment; head with or without a crest; last thoracic segments fused; lateral corners of last thoracic segment rounded; rostrum usually present; abdomen 4-segmented in female; genital segment often asymmetrical: caudal rami about as long as wide; A1 23-segmented; endopod of A2 shorter than half the length of exopod; 2nd basal segment of Mx1 long; exopod of P1 2-segmented; exopod of P2 to P4 3-segmented; endopod of P1 and P2 1-segmented; endopod of P3 and P4 3-segmented; coxa of female P4 with spines on the inner margin; P5 absent in female; male P5 biramous on the right; left leg with a rudimentary endopod.
For Vervoort (1957, p.63) there is a great deal of confusion concerning the limitations of the genera Euchirella and Pseudochirella, representatives of which resemble each other in many respects. The menbers of the genus Euchirella (known in 1957), all have a reduced number of setae on the 2nd basal segment and on the endopod of Mx1 (2-3 and 4-6 respectively) ; in Pseudochirella this number is increased (5 and 14-16 respectively). The endopod of A2 is reduced in nearly all Euchirella’s (it is less than half the length of the exopod in many species and about half that length in some others ; it is, however, much less reduced in Pseudochirella. Both Euchirella and Pseudochirella are characterized by the presence of a spine or spinules on the posterior surface of the 1st basal segment of P4. Euchirella brevis Sars (1905), approaches genera Gaetanus by the presence of thin, tube like spinules ; all other species have stronger spinules or a single strong spine. Ann additional difficulty in both genera is the scarcity of adult males and the obstacles encountered when trying to identity both sexes of a species. |

| | Rem.: | Type: Lutamator hurleyi Bradford, 1969. 3 spp.).
Diagnosis from Bradford (1969, p.491) [provisionally until further species are discovered] :
- head and 1st thoracic segment 1fused, 4th and 5th thoracic segments fused.
- Posterior thoracic borders extended into short points .
- Rostrum bluntly rounded.
- Posterior borders of abdominal segments edged with a weakly chitinised striated fringe.
- A1 24-segmented with long antennulate setae.
- A2 endopod and exopod equal; segment 1 of endopod wider proximally than distally; exopod tapers distally, segments 1 and 2 with 1 and 2 setae.
-- Md palp large.
- Mx1 inner lobe 1 (arthrite) with 11 spines and setae.
- Mxp basipod 1 twice as long as wide.
- P1 endopod 1-segmented.
- P2 endopod 2-segmented, all other rami 3-segmented; external spines on exopods large. Teeth on terminal spine of exopods connected by a lamella.
After Markhaseva & Schulz (2008, p.33) female specimens of Prolutamator share with Lutamator Bradford (1969) the following features: 1- rostrum as a poorly developed blunt plate; 2- A2 exopod nearly as long as endopod; 3- Md endopodal segment 2 with fewer than 7 setae; 4- coxal endite of Mxp syncoxa without sensory element; 5- P5 absent.
Except for the above characters (1-4) the genus Lutamator was defined by: 1- A2 endopodal segment 1 wider proximally than distally; 2- A2 exopodal segment 1 with 1 seta; 3- number of setae on the praecoxal arthrite of Mx1 reduced (11 setae). Its definition was considered tentative ''until further species are discovered'' (Bradford, 1969).
The genus was redefined by Alvarez (1984) and two species were included (L. hurleyi, L. elegans). The redefinition in genertal follows the earlier definition, but unfortunately has a misleading sentence that lacks the correct name of the described limb. |

- Posterior surfaces of P2 to P4 partly covered by spinules.
- P5 present, uniramous, indistinctly 3-segmented; apical segment small bearing spines or spine-like projections.
Male:

The new genus differs from Aetideopsis, Bradyidius, Pseudotharybis in relative length of A2 endo- and exopod: while in these three genera the exopod is distinctly longer than the endopod (ca. 1.2 - 1.5 times), in Parabradyidius these rami are subequal or the exopod may be even slightly shoryter. In addition, Parabradyidius lacks the medial seta of the A2 7th exopodal segment present in these three taxa. |

| | Rem.: | Type: Pterochirella tuerkayi Schulz, 1990. Total: 1 sp.
This genus shows affinities with Bradyetes and Pseudeuchaeta.
Diagnosis from Schulz (1990, p.182) :
Male :
- Cephalosome and 1st pedigerous somite fused, 4th and 5th pedigerous somite fused.
- Dorsal body wall of prosome transformed into deep transverse cleft encompassed by number of paired lobe-like structures.
- 1st pedigerous somite with paired winglike extension.
- Urosome 5-segmented.
- Rostrum absent, 2 delicate filaments present.
- A2 with endopod equaling exopod in length.
- Mouthparts considerably reduced.
- Endopods of P1 1-segmented, of P2 2-segmented, all other rami 3-segmented.
- P5 biramous with left and right protopod of about equal length, not swollen; endopods 1-segmented; exopods 2- to 3-segmented; distal segment of right side particularly long, tapering distally.
For Schulz (1990, p.187) according to Bradford & Jillett (1980) several features of this genus point to the family Aetideidae. In the male sex: 1 - fusion of cephalosome with 1st pedigerous somite and of somites 4 and 5; 2 - reduction or total lack of a rostrum; 3 - reduced number of segments of A1, swollen proximal segments armed with many large club-shaped aesthetascs; 4 - considerably reduced mouthparts; 5 - segmentation of P1 to P4, and pronounced, acute teeth on terminal spines of P2 to P4; 6 - presence of both endopods on P5. Furthermore, the presence of rows of spinules on the prominent outer lobe of the endopod of P1, described by Vaupel-Klein (1972) for the genus Euchirella, seems to support this classification. Pterochirella differs from both genera in the incomplete fusion of segments 9 and 10, 12 and 13, and complete fusion of segments 24 and 25 of the A1. Segments 20 and 21 are fused on the right but separate on the left A1. Furthermore, Pterochirella lacks the extraordinarily strong spine on lobe 5 of the Maxilla typical of Bradyetes. P5 of Pterochirella is distinguished from those of Bradyetes and Pseudeuchaeta by the comparatively short left protopod and the relative length of the endopods of which the right one is longer than the left. Morever, the right exopod terminates in a more or less straight distal segment, not curved as it is found in the other genera..
Pterochirella is assignable to the subfamily Euchirellinae of Brodsky (1950 [1967]) characterized particularly by 1- the more complex structure of male P5 and 2- the shortened urosome in the female (absent still in 2015). |

For Tanaka (1957 b, p.205) the genus Valdiviella was created by Steuer (1904) to accomodate a new species (V. oligarthra which is closely related to Euchaeta and also to some genera of Aetideidae.
According to Steuer, the genus has the mandible similar in structure to those of Gaetanus and Chiridius; Mx1 as in Undeuchaeta; Mx2 as in Aetideus, thus the genus Valdiviella is regarded as a member of the family Aetideidae, whereas Sars (1925, p.98) doubts of this justification. A. Scott states that ''the genus is closely related to Euchaeta, but easily recognised by its bifurcate rostrum; the incomplete segmentation of the exopodites of P1 and P2, and indistinctly 3-segmented endopodites of P3 and P4''.
- The genus has general appearance as in Euchaeta; head and 1st thoracic segment fused, 4th and 5th thoracic segments fused; posterior margin of last thoracic segment rounded; abdomen 4-segmented; appendicular seta short; endopod of A2 about as long as exopod; endopod of Md about as long as exopod;
- Mx1 differs from that of Euchaeta : setae on endopod and 2nd basal segment much reduced, endopod with only 3 setae, 2nd basal with 3 setae whereas that of Euchaeta with 3+3+3 setae on endopod, and 5 on 2nd basal segment;
- Mx2 resembles that of Aetideidae, setae on 5th lobe strong; Mxp resembles that of Undeuchaeta and Euchaeta, but row of spinules on anterior margin of 2nd basal segment are situated on the proximal half, wherea, it is on the distal half in Euchaeta, and thet are feeble.
- P1 as in Euchirella : 1st and 2nd exopodal segments fused; endopod of P2 1-segmented, that of P3 2-segmented; P4 exopod and endopod 3-segmented each; P5 absent in female; male P5 resemble those of Chirundina. The genus has a closer relationship to Aetideidae : rostrum resembles that of Aetideopsis or Undinopsis in its bifurcate shape;
Mx1 has the reduced number of setae on endopod and on 2nd basal segment.
- Mx2 as those of Aetideus in having 1 strong seta on 5h lobe (= endite).
- P1 similar to those of Euchirella.
- P2 as in Euchirella or Undeuchaeta.
- The genus has resemblance to Euchaeta: general appearance, structure of A1, Md and Mxp. Thus Valdiviella has the generic characters common both Aetideidae and Euchaetidae; it is intermediate form between Undeuchaeta and Euchaeta. For the author it seems reasonable, as Steuer stated, to accomodate it in the family Aetideidae.
For Vervoort (1957, p.87) the genus, in many respects, takes an intermediate position between the Aetideidae and the Euchaetidae. It approaches the Aetideidae in the structure of the rostrum, swimming legs, in the case of males, the structure of P5. The structure of Mxp shows unmistakable affinities with the Euchaetidae.
The belonging of this genus to this family is discussed by Heptner (1971) and by Zvereva (1975).
