First record of ovigerous Callinectes sapidus (Rathbun, 1896) in the Gargano Lagoons (south-west Adriatic Sea)

Since August 2015, an increasing number of Blue Crabs, Callinectes sapidus Rathbun, 1896, have been reported in the Marano and Grado Lagoon, Gulf of Trieste, in the northern Adriatic Sea. This species is not a new introduction and in fact the first record of C. sapidus in Italy and the entire Adriatic Sea dates back to 1949 in the Grado Lagoon. Interestingly, no other records of C. sapidus have been reported since the first record. Here, we note the re-appearance of C. sapidus in the Gulf of Trieste.

AbstractThe data presented in this paper are based on the observation of 52 individuals of Callinectes sapidus Rathbun, 1896, collected in August and September 2010 by local fishermen using gillnets and traps in the area of the delta of the river Neretva (Croatian coast, south-eastern Adriatic Sea). Carapace width (CW) and carapace length (CL) frequency distributions indicate 3 age cohorts (modes) (CL: 7.2 cm, 8.4 cm, 9.0 cm; CW: 12.2 cm, 14.9 cm, 16.7 cm). The carapace width (CW)-to-weight (W) relationship was calculated (for both sexes) as W = 0.816CW2.281 (r2 = 0.785). The current substantial records, the occurrence of ovigerous females and juveniles (observations by fishermen through visual census), as well as the fact that the species was regularly caught in the estuarine area, together constitute evidence of an established population of this species in the region investigated. In future, continuous monitoring of the C. sapidus population, the dispersal of the species in areas adjacent to the one now investigated, as well as all along the eastern Adriatic coast, will be necessary.

Richness Estimators

The aquatic oligochaete fauna of Montenegro was recently studied in order to improve the knowledge of this group in the Balkan region. This study was carried out on sediments collected from 70 sampling sites (the Black Sea and the Adriatic Sea drainage basins) during three years (2005–2008). Forty-one species were identified, from seven following families: Naididae, Enchytraeidae, Haplotaxidae, Lumbriculidae, Lumbricidae, Criodrilidae and Branchiobdellidae (exclusive of Naidinae and Pristininae). Sixteen of them represent first record for the Montenegrin oligochaete fauna: Embolocephalus velutinus, Ilyodrilus templetoni, Psammoryctides deserticola, Spirosperma ferox, Tubifex ignotus, Bathydrilus adriaticus, Bothrioneurum vejdovskyanum, Rhyacodrilus coccineus, Cernosvitoviella atrata, Enchytraeus buchholzi, Mesenchytraeus armatus, Haplotaxis gordioides, Rhynchelmis limosella, Stylodrilus heringianus, Tatriella slovenica and Trichodrilus strandi. The list of species from the subfamilies Naidinae and Pristininae was published previously (Šundić et al. 2011), and it comprises 36 species. Altogether, the present study and literature data show that Montenegrin aquatic oligochaete fauna consists of 77 species. Concerning similarity, values of Jaccard’s index are the highest between Montenegrin and Serbian oligochaete fauna (57 %), and the lowest between Montenegrin and Albanian oligochaete fauna (27.77 %). Species richness estimators (Mao Tau, Uniques Mean, Chao 1, Chao 2, Jack 1, Jack 2, Bootstrap, ACE and ICE) indicate that findings of new oligochaete species in Montenegro are expected.

Microlipophrys adriaticus (Steindachner & Kolombatovic, 1883) is an endemic blenny of the Mediterranean Sea. It is also known from the Sea of Marmara and the Black Sea. However, unlike other species of combtooth blennies, M. adriaticus is a fish with a limited distribution in Adriatic Sea, especially in the north, where it can be common. We report here the first record of this species from the waters of the Ionian Sea.

Molluscan Species

The state of the knowledge about the marine alien molluscan species from Italy is provided based on a critical review of records compiled from an extensive literature survey and from unpublished data obtained from 2005 to 2010. Based on the IUCN definition of ‘alien’, 35 molluscan taxa (18 Gastropoda, 16 Bivalvia and 1 Cephalopoda) are reported here, for each of which the following data (collected up to December 2010) are provided: published and unpublished records from the coastal and offshore territorial seawaters of Italy, including lagoons, within the 14 biogeographical sea divisions covering the Italian shores, date of first record, most plausible vector(s) of introduction and establishment status. The southern Ionian Sea, the northern Adriatic Sea and the eastern-central Tyrrhenian Sea resulted to be the areas most affected by alien molluscan introductions. The rate of records of new alien species (evaluated on the basis of live findings) is quite uniform over five decades, with six to eight species recorded per decade. The analysis of the vectors showed shipping/maritime transport to be the most common vector of introduction (40%), followed by trade (24%). Nineteen alien molluscan species (54%) were considered as established in Italy.

Gryllotalpa weisei Simeu-Noutchom & Kekeunou sp. nov. was collected only in Tombel in the South-West region of Cameroon, during a survey conducted from March 2016 to March 2018 in the West, South-West and Centre regions of Cameroon. This species is close to Gryllotalpa microptera, collected for the first time in Cameroon during these investigations, only in the West region. G. weisei is different from G. microptera due to the hind wings that are vestigial; average fore wings length of 5.85±0.56 mm in male and 5.34±0.45 mm in female, not reaching the fifth abdominal segment; anal end of fore wings slightly concave; a stridulatory file with 54±8.02 teeth (47–71) in average, fairly spaced, with an average of 30±5.06 teeth per millimeter; hind tibia bearing 11 spines; internal process of ectophallus quite short. G. weisei abounds in mixed crop fields, followed by cocoa agro-forests; it is scarce in grassy fallows and in forest undergrowth. G. microptera was present in all types of vegetations in Bafoussam, Babeté and Bangoulap in the West region where it has been abundant in mixed crop fields, grass-fallow and coffee agro-forest but rare in forest undergrowth.
