Keys to Aid in the Identification of Marine
Harpacticoid Copepods

Amendment Bulletin No. 2.


This second bulletin of amendments to my Keys (Wells, 1976, 1978) deals with additions and alterations made necessary by recent publications and takes another opportunity to correct errors. Once again I wish to thank my colleagues for information received and to encourage them to continue sending it for incorporation in future bulletins. Page numbers in parentheses are those of the original Keys (Wells, 1976).

Family Gelyellidae

Gelyella droguei Rouch & Lescher-Moutoué, 1977, a new genus and species, is the sole species in a new family of primitive freshwater harpacticoids which tends to link together Lang's (1948) primary divisions of Polyarthra and Oligoarthra. The Key to Families (p.5) requires modification of couplet 5 as follows—

5. P.4-P.5 absent. Gelyellidae
P.4-P.5 present. 5a
5a. Distal segment of Enp. P.2 much longer than the entire Exp. Longipediidaea)
Distal segment of Enp. P.2 shorter than the Exp. Canuellidae

Family Cerviniidae

Dinet (1978) describes nine new species of Pontostratiotes — P. uxoris, P. gladius, P. lubricus, P. vitelloi, P. viverae, P. denticulatus, P. cecilae, P. vasconensis, P. barnetti. All are referable to the genus codon in KGG 1 (p.21), as in P. pori, nom. nov. by Dinet (1978) for the P. abyssicola of Por (1969). Add to General Note 2 (p.26).

Family Ectinosomatidae

1. Arenosetella fimbriaticauda McLachlan & Moore, 1978, to genus codon in KGG 1 (p.28). Add to General Note 2 (p.36).
2. Ectinosoma barbicauda Bozic, 1978, to genus codon in KGG 100 (p. 29). Add to General Note 2 (p.36).
3.McLachlan & Moore (1978) have re-examined Hastigerella tenuissima, H. palpilabra and Arenosetella, monensis. They show that all possess a weak ornamentation of the anal segment and, further, that in all respects they are identical and must be considered synonymous. The senior synonym is H. tenuissima which must be transferred to Arenosetella and added to the genus codon in KGG 1 (p.28). Delete the codons for H. tenuissima and H. palpilabra in KGG 300 (p.33) (see also Wells, 1978 p.1, for Arenosetella monensis).
page 2

Family Darcythompsoniidae

Kunz (1978) describes a specimen that he believes to be the previously unknown male of Leptocaris minimus Jakobi. This male has P.1-P.4 Enp.2 with 3:3:3:2 setae and lacks a seta on P.3 Enp.1. Although Kunz was unable to examine the female he is convinced that the additional small setae illustrated by Jakobi (1954) are only accessory spinules. Therefore, the codon in KGG 1 (p.37) must be amended to read — a/a/4:4/0:0:0:0/3:3:3:2. A note that the male of this species has now been described should be made under General Notes (p.39).

Family Harpacticidae

1. Harpacticus furcatus is redescribed by Itô & Fukuchi (1978) ; add to General Note 1 (p.47).
2. Tigriopus igai Itô, 1977, to codon for Tigriopus b) in KGG 1 (p.43) ; add to footnote b) (p.44).
3. Harpacticella oceanica Itô, 1977, requires a new codon in KGG 100 (p. 46) — nor/7/1/ ♀ /5:5/0:4.
4.There are errors in the codons for Harpacticella spp. in KGG 100 (p.46) ; correct as follows—
Harpacticella d) nor/7/1/ ♀ /5:5/0:3.
H. paradoxa nor/7/1/ ♀ /5:5/0-1:3.

Family Thalestridae

1.Delete Paradactylopodia oculata from KGG 200 (p.62). This species requires a new codon in KGG 1 (p. 58) — 3:3/7 :8:7/2 :2/3/p :d.
2.There are several errors with regard to species of Pseudotachidius; correct as follows—
(a)in KGG 1 (p.58)
(i)delete the codon for P. coronatus and P. similis.
(ii)add a new codon for P. similis
(iii)add a new codon for P. vikingus ♀ —
(b)In KGG 200 (p.62) add a new codon for P. peruanus Becker, 1974—
4-5/1/less than or equal to Enp.1.
(c)in KGG 300 (p.63)
(i)add a new codon for P. coronatus
(ii)codon for P. vikingus refers to the male only.
(iii)delete the codon for P. peruanus.
3. Paradactylopodia hexarticulata is incorrectly spelt by Wells, (1978, p.3).
page 3

Family Diosaccidae

1. Pseudostenhelia wellsi Coull & Fleeger, 1977, to genus codon in KGG 1 (p.70) which now requires amendment as follows—
3/2/2/4/2-3:2-3:2-3; add to General Note 2 (p.99).
2. Haloschizopera latisetifera Marinov, 1973a, to codon for Haloschizopera a) in KGG 100 (p.72) ; add to footnote a) (p.73).
3.Delete Metamphiascopsis nicobaricus from footnote c) of KGG 260 (p.84) and add a new codon for this species in KGG 250 (p. 82—
4. Amphiascus longarticulatus Marcus (see Wells, 1978 p.3) is re-described by Bodin (1977). His specimens have a weak third inner seta on P.2 Exp.3. It is not known if this seta is present in Marcus's material. The species must now be added to footnote b) of KGG 260 (p.84). Bodin considers Amphiascus sp. Wells, 1968, to be this species.
5. Stenhelia (D) krishnensis Radhakrishna & Reddy, 1978, to codon for S. madrasensis in KGG 500 (p.88). These two species probably are synonymous.
6. Protopsammotopa wilsoni Wells, 1977, to genus codon in KGG 1100 (p.98) ; amend entry in General Note 2 (p.99).
7.Add Schizopcra issykkulica Mauyilova, 1966, to General Note 4 (p. 99).

Family Ameiridae

1. Ameira scotti has been omitted from the Keys; add a new codon in KGG 400 (p.114)—
0:0:0/1 :1:1/1:1 :1/4:5:5/4:5/2:4.
2. Ameira longipes: The first codon for this species in KGG 400 (p. 115, line 1) must be deleted. The true codon is the last one on this page.
3. Parevansula elegans (Marinov, 1974) requires a new codon in KGG 1 (p.101)—
3:2/2:2:2 1:1:2/4/0. This species is assigned by Marinov to the genus Philoleptomesochra, but see General Note 2 (p.122).
4. Nitocra sewelli husmanni is incorrectly spelt by Wells (1978, p.4).

Family Paramesochridae

1. Apodopsyllus unguiformis Coull & Hogue, 1978, to codon for A. africanus and A. schulzi in KGG 300 (p.129).
2. Apodopsyllus bermudensis Coull & Hogue, 1978, is described for all the previous records of A. africanus from Bermuda; add a new codon in KGG 300 (p.129) —
2/4/0:4/1:2 and make an appropriate note in General Note 1 (p. 130).
3. Apodopsyllus perplexus appears incorrectly in KGG 300 (p.129) as A. reductus. This species was originally described as Leptopsyllus reductus Petkovski, 1955, but as this is a junior primary homonym of L. reductus Lang, 1948, the name must be permanently rejected (Article 59(a) of the International Code of Zoological Nomenclature, page 4 1964). This was overlooked by Kunz (1962) in his revision of the family, in which he removed L. reductus Petkovski to Apodopsyllus but retained the homonymous trivial name. The homonymy was recognised by Wells (1963) who proposed replacement by Leptopsyllus perplexus nom. nov. This replacement name has priority over L. petkovskii nom. nov., proposed by Noodt (1964). Thus the correct name for L. reductus Petkovski is Apodopsyllus perplexus (Wells, 1963).

Family Tetragonicipitidae

1. Phyllopodopsyllus laspalmensis Marinov, 1973b, to codon for P. mossmani in KGG 1 (p.133).
2. Phyllopodopsyllus paramossmani: Amend the codons in KGG 1 (p.133) to read—
The male must be added to the codon for P. longipalpatus ♂.

Family Canthocamptidae

1. Mesochra flava as redescribed by Soyer (1977) differs from the original description of Lang (1933). As his material is not from the type locality Soyer's specimens must be considered only as showing that there is some geographic variability in the species. Therefore a second codon is required for this species in KGG 100 (p. 137)—
2. Mesochra pallaresi Soyer, 1977, is described for Pallares' (1968, 1975) specimens of M. flava. M. pallaresi must be added to the original codon for M. flava
7/3/6:7:7/5:5/6:5/3:6 (KGG 100, p.137) ; add an appropriate note in General Note 3 (p.139).

Family Cylindropsyllidae

1. Notopontia stephanieae Bodiou, 1977, a new genus and species, requires a new codon in KGG 1 (p. 141) —
2. Stenocaris kerguelenensis Bodiou, 1977; the female to the codon for S. minor and S. kliei and add a new codon for the male—
2:1:2/ns/2:2/na (both in KGG 200, p.143).
3.KGG 300 (p.144)—
(a)Character 2 should read "P.1 Enp.".
(b) Leptastacus naylori McLachlan & Moore, 1978, requires a new codon—
p/2/0:0:1/3:4:5/1:1:0/1 :2:1.
4.KGG 500 (p.148)—
(a)Character 1 should read "P.1 Exp."; there is only one segment in this ramus.
(b) Psammastacus erasmusi McLachlan & Moore, 1978, to codon for P. spinicaudatus.
5. Arenopontia (N.) sakagamii ltô, 1978, to codon for Arenopontia c) in KGG 600 (p.149); add to footnote c) (p.150).
page 5

Family Cletodidae

1.KGG 1—
(a)Delete the codon for Eurycletodes (O.) arcticus (p.158). This species must be be added to the codon for E. (O.) latus (p.157).
(b) Eurycletodes aberrans Marinov, 1973b, cannot be placed in either subgenus as it displays features of both; add to codon for Mesocletodes carpinei Soyer (p.154; see also Wells, 1978, p.7).
(c) Nannopus palustris: Coull & Fleeger (1977) comment on the variability of this species, in particular on the setation of P.2-P.4. The present codon (p.157) must be amended to take these comments into account—
3:2/3:3:3/2:1/6-7:7-8:6-8/3:2 and an appropriate note must be inserted in General Note 1 (p.170).
(d)Add Cletocamptus affinis to footnote e) (p.159).
2. Cletodes reductus Moore, 1977, requires a new codon in KGG 600 p.167)—
3. Argestes mollis: Amend the codon in KGG 700 (p.169) to read—

Family Laophontidae

1. Laophonte longicaudata s.str.: Amend the present codons as follows—
KGG 1300-♀ ♀ (p.183) 6:7:7/1:1:1/0:0:0 4:6:3 0:0:1.
KGG 1000-♂ ♂ (p.196 6:7:7/1:1:1/4:4:3/0:1/p.
2. Laophonte euxiniphila Soyer, 1977, requires new codons as follows—
KGG 2100-♀ ♀ (p.187) 5:5:5/1:1:1/0:0:0/3:5:4 0:0:0.
KGG 1- ♂ ♂ (p.188) 3:3:3/2:2/2:3/3/3.
3. Heterolaophonte stroemi: P.4 Exp.3 can have five or six setae. Add a second codon in KGG 1900. ♀ ♀ (p.185)—
6:6:5/1 :1 :1/0:0:0/4:6:4/0:0:0.
4. Heterolaophonte longisetigera: Dr G. R. F. Hicks (pers. comm.) reports that in English material of this species the P.5 ♂ setation is variable, with a total of five or six setae, and that P.3 Enp. is always three-segmented. Therefore this species must be added to the codon for Apolethon in KGG 1- ♂ ♂ (p.190).
5. Echinolaophonte mirabilis is incorrectly called E. mirabilipes in KGG 1- ♀ ♀ (p.174).
6. Echinolaophonte armiger. Amend the present codon in KGG 300- ♀ ♀ (p. 177) to read—
5:6-7:6/1 :1 :1/0:0:0/3:4:3/0:0:0.
7. Klieonychocamptus kliei ponticus Marcus, 1971, is a junior secondary homonym of K. ponticus (Serban & Plesa, 1957). I propose K. k. marcusi nom. nov. as a replacement name (see p. 175, footnote e) and p.190).
8. Pseudolaophonte glemareci Bodin, 1977, requires new codons as follows:—
KGG 1- ♀ ♀ (p.172) 2:2:2/0:1:1/5:5/2/5.
KGG 1- ♂ ♂ (p.188) 2:2:2/0:1/2:3/2/2.
page 6
9.Transpose columns three and four of the codon for Laophontopsis lamellifera in KGG 1600-♀ ♀ (p.184).
10. Cubanocleta noodti Petkovski, 1977, a new genus and species, is placed by its author in this family even though the A.2 lacks an exopod. Thus, it keys out to the family Ancorabolidae in the Keys to Families (p.8, couplet 24). It requires new codons as follows—
KGG 1- ♀ ♀ (p.172) 3:3:3/1:1:1/4:3/3/4.
KGG 1-♂ ♂ (p.188) 3:3:3/1:1/4:3/3/1.
11. Laophonte spinifer is incorrectly spelt by Wells (1978, p.7).
