Sigara (Halicorixa) stagnalis stagnalis (Leach, 1817) ( Corixa: Corixinae )

Asian Turkey. Topkara et al. (2010).

General distribution. The nominotypical subspecies is distributed along the coasts of western Europe ( Sweden, Poland, Germany, Denmark, the Netherlands, Belgium, France, Ireland, Great Britain, Portugal, Spain, Italy) and north-western Africa ( Morocco, Algeria,? Tunisia) ( Jansson 1986a, 1995; Kment 2006a). The record from the Czech Republic ( Jansson 1986a, 1995) is probably because of a mislabeling ( Kment & Smékal 2002). The records from Bosnia and Herzegovina, Croatia, and Macedonia ( Protić 1998), without indicated suspecies, need further confirmation. Sigara stagnalis pontica Jaczewski, 1961 is distributed along the Black Sea coast of Bulgaria, Romania, Moldavia, Ukraine, and Russia ( Jansson 1995, Derjanschi 1995, Prokin et al. 2008). This is a halobiont species (e.g., Savage 1989, Kment 2006a).

Comment. Topkara et al. (2010) reported this West Mediterranean taxon from a brackish water channel connected with the Gediz River (near Maletepe village) in the İzmir province (western Anatolia). They accompanied their report with line drawings of the male pala and left and right paramere. However, comparing these drawings with the excellent ones by Jansson (1986a), the pala resembles those of S. stagnalis stagnalis by its general shape, but it is wider basally and also the patch of setae on its dorsal margin resembles S. mayri . The shape of right paramere much more corresponds with S. mayri , and the shape of apical processes is a bit similar to S. stagnalis pontica . The identity of the Halicorixa species recorded by Topkara et al. (2010) thus needs final confirmation.

Identification. Jansson (1986a).
