Balgetia cf. semicirculifera Karling in Luther, 1962

( Figure 9C )

Material examined

Sites 3, 7: several specimens, in squash preparation.

Geographical distribution. Baltic Sea: Gulf of Finland (Tvaerminne: Henriksberg, Balget), Sweden (Östergötland: St Anna, Vrangö); Øresund (Nivå Bay); North Sea: Norway, North Frisian Islands (Sylt) ( Luther 1962; Straarup 1970; Hellwig-Armonies 1988).

Remarks

The species was found in fully marine habitats. To date Balgetia semicirculifera has only been found in oligohaline habitats of the Baltic Sea ( Luther 1962) and in saltmarshes of the Island of Sylt ( Armonies 1987). The stylet of the Scilly form looks rather different: the proximal and median part is straight and only the distal part is curved ( Figure 9C ) (cf. Luther 1962: 33, Figure 12D, E).
