Five station records (20, 23, 33, 33 and 152 specimens), St Mary’s Flats, 15 to 17 October 2004 (Warwick in MarLIN). (All as Apseudes latreilli .)
From quantitative surveys on St Martin’s Flats (see Warwick 2010), in summer 2000 densities in the Ensis -community off Old Quay averaged 54 individuals per m 2, and in the Arenicola -community near “Neck of the Pool” two individuals per m 2; in 2004 the species was only found in the Ensis -community, at densities of 522 individuals per m 2; none were found in any samples in 2001 (restricted survey) or 2009 ( R. Warwick, unpublished data).
Remarks
Apseudopsis latreilli is common in the littoral and near-littoral sands of the Isles of Scilly (frequently observed, rarely recorded), and can be particularly numerous, as found consistently over the years on St Martin’s Flats, although that population appears to have collapsed in 2009 (see above and Warwick 2010) and few individuals were found there in September 2010. As stated above, it is largely separated in habitat from the deeper-occurring Apseudes talpa (that species not occurring in the open sand-flats), although some of the early deeper records of the present species in litt. may have confused the two. These two species were sympatric (although infrequent) in low-littoral Audouinella -bedded sand.
Holdich and Jones (1983) list the occurrence of this species in the Isles of Scilly, as well as from southern coasts of England, the Channel Isles and French coasts (their records from northeastern coast of England are based on a lapsus calami by Bate and Westwood 1868, see Bamber 2000).
