Updated status of Anostraca, Notostraca and Spinicaudata...  7

              precise geographical location. To date, four anostracan, two notostracan and
              three spinicaudatan taxa have been recorded on the island.
                  Lepidurus apus lubbocki is the first large branchiopod ever sampled in
              the island (BRAUER, 1873, 1877). The presence of this taxon in the island is
              confirmed by GURNEY (1909), who studied a Sicilian specimen of “Lepidurus
              lubbocki”. After that, several authors (GHIGI, 1921; LONGHURST, 1955;
              COTTARELLI & MURA, 1983; BRTEK & THIÉRY, 1995) reported the presence of
              L. apus lubbocki in Sicily quoting Brauer’s papers. Lacking any recent record
              of specimens belonging to the genus Lepidurus in Sicily, the current presence
              of this species on the island needs to be confirmed.
                  GHIGI (1921) is the first author who reports the presence of “Thriops can-
              criformis” (= Triops cancriformis) in Sicily. The specimens he studied, sent him
              by the “Museo di Palermo”, included males. An apparently gonochoric popula-
              tion (the sample consisted of 3 males and 2 females) was, in fact, found on Fav-
              ignana island by COTTARELLI & MURA (1995). Conversely, ZAFFAGNINI & TREN-
              TINI (1980) worked on a maleless Triops cancriformis population from Punta
              Raisi, near Palermo. Other Triops cancriformis populations were recently found
              on Ustica island (MARRONE, 2003), on Monte Cofano (MARRONE & NASELLI-
              FLORES, 2004) and on Favignana island (MARRONE & NASELLI-FLORES, 2005).
              Specimens from the Monte Cofano pond have been studied by MANTOVANI et
              al. (2004). Conversely, the reports on the presence of Triops granarius in Sicily
              (THIÉRY, 1987; CHAMPEAU & THIÉRY, 1990) are erroneous and based on the mis-
              understanding of two works by COTTARELLI & MURA (1979, 1983).
                  DADAY DE DEÉS (1914) reported the presence of  Cyzicus cycladoides
              (Joly, 1841) in Sicily. Unfortunately, the location of the site where the speci-
              mens he studied were collected was not specified. GURNEY (1909) reported
              that “Estheria cycladoides” is “widely distributed in North Africa and occurs
              also in Southern France, Spain and Sicily”. COTTARELLI & MURA (1979) col-
              lected C. tetracerus in a pool at Torre dell’Orsa (Palermo province) and point-
              ed out that this species cannot be told apart from C. cycladoides based on
              morphology, the latter being possibly a synonym of the former. A population
              of C. tetracerus was recently found on Monte Cofano (MARRONE & NASELLI-
              FLORES, 2004).
                  Two Leptestheriidae species are reported in Sicily: Leptestheria daha-
              lacensis and Leptestheria cf. cortieri. L. dahalacensis is reported by DADAY
              DE DEÉS (1923) on the basis of specimens stored at the Museum of Natur-
              al History of Berlin.  Leptestheria  cf.  cortieri was collected in Mortelle
              (Messina province) by COTTARELLI & MURA (1979). The identification of
              the  Leptestheria from Mortelle as  L. cortieri raises some doubts, as the
              authors themselves wrote (COTTARELLI & MURA, 1979, 1983). THIÉRY
