ANAITIDES LONGIPESKINBERG, 1866 (POLYCHAETA: PHYLLO

DOCIDAE): NOTES ON NOMENCLATURE, IDENTIFICATION, HABITAT AND DISTRIBUTION

Benthic studies off the Irish south and west coasts yielded several specimens of a

phyllodocid polychaete answering the description of both Phyllodoce longipes Kinberg, 1966 and Anaitis jeffreysii Mcintosh, 1908. Examination of the types (held in the

Naturhistoriska Riksmuseet, Stockholm, Catalogue, No. 632 and in the British Museum

(Natural History), London, Catalogue No. 1921: 5: 1:962 respectively) and a range of other

specimens of both species, and also of the recent Irish material, made it clear that nomenclatural revision was necessary. In studying the literature related to the specimens, it becomes possible to make some comments about the species' habitat and range.

Examination of holotypes of both taxa makes it clear that they are the same species, and would now be included in the genus Anaitides Czerniavsky, 1982, as A. longipes.

Anaitis jeffreysii is therefore considered a junior synonym. It is unclear why Mcintosh and Southern (1914) placed this species within Anaitis/Paranaitis respectively, as it lacks the

principal taxonomic character of this genus. Species identification in the genus Anaitides is often difficult (as for example in the

species pair A. mucosa/maculata). However, A. longipes is distinctive, as the specific epithet suggests, in having elongated, pointed upper lobes of the neuropodia. It also has a

characteristic dark pigmentation of the first three post-tentacular segments, though this may fade after long immersion in alcohol. The tentacular formula is:

1 1 1 + o - + 0 - .

1 1 Day (1967) provides a description and figure, to which it may be added that a nuchal organ is sometimes visible in the occipital notch and in some specimens eversible nuchal lobes

may also be observed situated just below the outer rearward margins of the prostomium and

just anterior to the first tentacular cirrus. A. longipes has been recorded mostly from sand or muddy sand substrates except for

the type specimen which was taken from a kelp holdfast. Specimens have been taken in all

depths between the intertidal zone and 85m. The species is apparently rare in all localities, with not more than 50 specimens having been recovered in 100 years. However, it is of

apparently worldwide distribution, having been taken from Chile (Kinberg 1866, Ehiers

1901), southern Africa (Day 1967), Australia (Poore and Kudenov 1978), California

(Hartmann 1968), Oregon and Washington State (Kravitz and Jones 1979) and North Carolina (Day 1973). Irish records are from Valentia (Mcintosh 1914), Boffin island, Clew

Bay and Blacksod Bay (Southern 1914), Galway Bay (specimens provided by B. O'Connor and M. Coneely, UCG) and the western edge of the Nymph Bank off Cork (collected by the

author). Specimens of recent Irish material have been lodged in the National Museum of

Ireland, in the British Museum (Natural History) (Polychaete Catalogue No. ZK 1983:

335-337) and at the Zoologisches Museum, Hamburg (Catalogue No. P 16775).

LASIODIAMESA SPHAGNICOLA, CARDIOCLADIUS CAPUCINUS AND ORTHOCLADIUS (EUDACTYLOCLADIUS) FUSCIMANUS

(DIPTERA: CHIRONOMIDAE) NEW TO IRELAND P. ASHE

Department of Zoology, Trinity College, Dublin 2

A completely updated and revised checklist of the Irish Chironomidae was recently published (Murray and Ashe 1984). The three species included in this paper have not

previously been recorded from Ireland. The Irish grid reference and the UTM (Universal Transverse Mercator) grid reference are given for each record. Inclusion here of the UTM 50 km grid reference is to facilitate the eventual incorporation of data on Chironomidae into the European Invertebrate Survey distribution map scheme. Specimens of all three species have been deposited in the National Museum of Ireland, Kildare Street, Dublin 2.

Subfamily Podonominae

Lasiodiamesa sphagnicola (Kieffer)

The first member of the subfamily Podonominae to be recorded from Ireland was Parochlus

kiefferi (Garrett) which was only added to the Irish list relatively recently (Murray and Ashe 1984). In Britain both P. kiefferi and L. sphagnicola have been recorded (Coe 1950) and more recently a third

species, Paraboreochlus minutissimus (Strobl), was added to the British list (Langton 1984). L.

sphagnicola in Britain is only known from a single location, Austwick Moss, NW Yorks (Coe 1950),

and no further records are known (Cranston pers. comm.). On the European mainland the species is

recorded from Finland, Sweden, U.S.S.R., Poland, West Germany and East Germany (Brundin

1966).

According to Brundin (1966: 325) the larvae of this species in Swedish Lapland occur not only in

stagnant bog waters but also in oligohumic tarns and ponds, springs and the streamlets arising from

springs, predominantly in the birch belt but also above the timber line ? further southwards the

species is only known from Sphagnum bogs. The flight period of the adults is from April to September from the available records indicated in Brundin (op. cit.).

Invertebrates of Irish bogs are being studied by Dr J. Reynolds who collected and reared several

collections of chironomid larvae. This material was passed on to me for identification. Among this

material was a single larval exuviae and the associated pupal exuviae of L. sphagnicola. The larva was

originally collected, on 20th March 1985, from a Sphagnum pool near a stand of birch, Betula

pubescens Ehrh., on west Clara Bog, Co Offaly (N244301, NV. 4). On 18 April 1985 a collecting trip to the locality was organised and adult males (leg. M. de Courcy Williams) and additional larvae (leg. J. Reynolds and P. Ashe) were obtained. The Sphagnum pools (about 0.5?1.0m long, 0.3m wide) are small and shallow and associated with a slight flush (i.e. surface water movement or trickles which
