| Clytemnestridae A. Scott, 1909 ( Harpacticoida, Oligarthra ) | |
| | | (1) Clytemnestra Dana, 1848 | |
| | Rem.: | Type: Clytemnestra scutellata Dana,1847. Total: 6 spp.
Diagnosis from Huys and Conroy-Dalton in Bull. nat. Mus. Lond., 2000, 66 (1), p.5:
- Body without dorsal pattern of denticles or spinules on urosomites.
- A1 distinctly 7-segmented in both sexes (and not 8 in the female because the basal pedestal sometimes misinterpreted as an additional segment). Male segmental homologies : 1 (I) ; 2 (II-VIII) ; 3 (IX-XIII) ; 4 (XIV-XVII) ; 5, XVIII) ; 6 (XIX-XX) ; 7 (XXI-XXVIII). Segment 5 in male with large spine.
- A2 with 1 lateral and 5 apical elements on distal endopod segment. Exopod represented by well defined segment bearing 2 long setae.
- Mx1 represented by bilobated segment with 1 lateral setaz and 2 apical spines.
- Mx2 syncoxa with 1-2 endites ; proximal endite represented by very long seta, sometimes absent ; distal endite bearing 3 setae.
- P1 with outer seta on basis ; exopod with 4 setae.
- P2 without outer spine on exopodal segment 1.
- P1-P4 armature formula (see Table).
- P5 exopod with 5 or 6 setae in both sexes.
- Genital apertures paired in female ; closed off by paired P6 bearing 1 vestigial element ; copulatory pore small, located anteriorly between genital apertures ; copulatory duct probably very short and definitely not strongly chitinized.
- Male P6 almost symmetrical, fused medially forming membranous operculum closing off single median genital aperture ; produced into cylindrical process bearing 3 small setae.
- Caudal rami parallel, almost cylindrical ; sexually dimorphic with setae IV-V short and pinnate in female, long and multiplumose in male ; additional sexual dimorphism also noted in setae III and VI.
The revision of the genus by Huys & Conroy-Dalton (2000) introduces a serious doubt for the most part of the given references as for the geographical data before 2000. |

| | Rem.: | Type: Goniopsyllus rostratus Brady, 1883. Total: 3 spp. (+ 1 doubtful).
Diagnosis after Huys and Conroy-Dalton (2000, p.29):
- Body with dorsal pattern of denticles and spinules on urosomites.
- A1 6-segmented in female, indistinctly 7-segmented in male with segments 3-4 incompletely fused ; male segmental homologies : 1 (I) ; 2 (II-VIII) ; 3 (IX-XII) ; 4 (XIII) ; 5 (XIV-XVII) ; 6 (XVIII-XX) ; 7 (XXI-XXVIII).
- A2 with 1 lateral and 4 apical elements on distal endopod segment ; exopod represented by membranous segment bearing 1 long seta.
- Mx1 represented by triangular segment with 1 apical spine.
- Mx2 syncoxa with 1 endite bearing 2 setae.
- P1 without outer seta on basis ; exopod with 3 setae.
- P2 with outer spine on exopodal segment 1.
- P1-P4 armature formula (see Table).
- P5 exopod with 5 setae in both sexes.
- Genital apertures fused in female forming common medial slit; closed off by paired P6 bearing well developed seta; copulatory pore located medially in large circular depression halfway the length of the genital double-somite ; copulatory duct strongly chitinized.
- Male P6 asymmetrical, forming membranous opercula closing off single (sinistral or dextral) genital aperture ; bearing 1 seta.
- Caudal rami convergent, relatively short and conical; not sexually dimorphic.
All the localisations and the lengths indicated by the authors previous the revision of the genus by Huys and Conroy-Dalton (2000) are doubtful. |
