Mollusca: Veneridae) in the Western Pacific Ocean1
Genetic Relationships among Species of Meretrix (Mollusca: Veneridae) in the Western Pacific Ocean1 Ayako Yashiki Yamakawa,2,3,6 Masashi Yamaguchi,4,5 and Hideyuki Imai4 Abstract: We compared allozymes at 12 loci in 12 populations of six species of Meretrix: M. lusoria ( Japan, Korea, and Taiwan), M. petechialis (China and Ko- rea), M. ovum (Thailand and Mozambique), M. lyrata (China), M. lamarckii ( Ja- pan), and Meretrix sp. A (Okinawa, Japan). Our allozyme results were generally consistent with the major groupings currently recognized within the genus based on morphological characters. However, we found two cryptic or un- described species: Meretrix sp. A from Okinawa and M. cf. lusoria from Taiwan. The shell characters of Meretrix sp. A were similar to those of M. lamarckii, but the species was genetically distinct (Nei’s genetic distance D > 0.845) from all other species examined. The Taiwanese Meretrix population was morphologi- cally indistinguishable from Japanese M. lusoria, although the genetic distance between the Taiwanese and Japanese populations showed a high degree of ge- netic differentiation (D > 0.386). Meretrix lusoria seedlings were introduced into Taiwan from Japan in the 1920s, and Japanese M. lusoria was previously thought to be established as a cultured stock. However, our results suggest that the Taiwanese population may represent a sibling or cryptic species of M. lusoria. Asianhardclams, genus Meretrix (Vener- (Yoosukh and Matsukuma 2001).

Department of Zoology and Aquaculture, Acharya Darwin Ch. and P Padmavathi Nagarjuna University Nagarjuna Nagar, Abstract Andhra Pradesh, India Among the various groups represented in the macrobenthic fauna of the Bay of Bengal at Prakasam P Padmavathi district, Andhra Pradesh, India, molluscs were the dominant group. Molluscs were exploited for Department of Zoology and industrial, edible and ornamental purposes and their extensive use has been reported way back from time Aquaculture, Acharya immemorial. Hence the present study was focused to investigate the diversity of Molluscan fauna along Nagarjuna University the Paleru and Moosy backwaters of Prakasam district during 2016-17 as these backwaters are not so far Nagarjuna Nagar, explored for malacofauna. A total of 23 species of molluscs (16 species of gastropods belonging to 12 Andhra Pradesh, India families and 7 species of bivalves representing 5 families) have been reported in the present study. Among these, gastropods such as Umbonium vestiarium, Telescopium telescopium and Pirenella cingulata, and bivalves like Crassostrea madrasensis and Meretrix meretrix are found to be the most dominant species in these backwaters. Keywords: Malacofauna, diversity, gastropods, bivalves, backwaters 1. Introduction Molluscans are the second largest phylum next to Arthropoda with estimates of 80,000- 100,000 described species [1]. These animals are soft bodied and are extremely diversified in shape and colour. -

MALAKOLÓGIAI TÁJÉKOZTATÓ MALACOLOGICAL NEWSLETTER 2001 19: 95–101 Data to the malacofauna of Katavothres (Kefalinia, Greece) E. De Smit–K. Bába Abstract: The authors evaluated the samples collected by Marninus De Smit in 1999 at the collection site of Katavothres, on the isle of Kefalinia, Greece. Key-words: Katavothers, Greece, Marin mollusc fauna Material and methods Sample collections were carried out in a southern bay of the isle of Kefalinia, on the coast of Katavothres (09.06.1999.) For the determination of the order of families we used Poppe, G. T.–Gotto, Y. (1991–1993) Vol. I-II. For the identification of species we gave preference to the following publications: Nordsieik, F. (1968, 1969, 1972) Poppe, G. T.–Gotto, Y. (1991, 1993), D’ Angeló–Gargiullo, S. (1978) and also Ghisotti, F.–Melone, G. (1971, 1972, 1975) Results The collections yielded species from Scaphopoda, Lamellibranchiata and Gastropoda class- es. Altogether 7697 individuals belonging to 188 species were collected. (Scaphopoda: 1 family 1 species, Lamellibranchiata: 30 families 90 species 3811 specimen, Gastropoda: 42 families 188 species 7697 specimen). From the Bivalvia the Musculus laevigatus is a cir- cumpolar, the Hiatellidae: Hiatella arctica is a boreal circumpolar species. From the Gastropoda the Trochidae: Clanculus striatus, Phasianellidae: Tricolia miniata are known as belonging to the Southern Mediterranean. Most probably they spread due shipping. From most of the species encountered 1-40 individuals were found. More than 100 indi- viduals were collected from the species below: Jujubinus striatus, Gibbula philberti, Truncatella subcylindrica, Alvania consociella, Bittium latreilli, Bittium reticulatum, Cerithium alucaster, Gibberula miliaria, Granulina clandestina. Summary From the alluvial deposits on an island near Greece 11 508 individuals from 279 species of 72 families from 3 orders were encountered. -

Stagno d’Al - contres 31, 98166 Messina, Italy; e-mail: [email protected] 2Via Bologna, 18/A, 87032 Amantea, Cosenza, Italy; e-mail: [email protected] ABSTRACT First quantitative data on mollusc assemblages from the Capo d’Armi cliff, at the south en - trance of the Strait of Messina, provided a baseline for monitoring changes in benthic biod- iversity of a crucial Mediterranean area, whose depletion might already be advanced. A total of 133 benthic taxa have been recorded, and their distribution evaluated according to depth and seasonality. Bathymetric distribution showed scanty differences between the 4-6 meters and 12-16 meters depth levels, sharing all the 22 most abundant species. Season markedly affected species composition, since 42 taxa were exclusively recorded in spring and 35 in autumn, contrary to 56 shared taxa. The occurrence of some uncommon taxa has also been discussed. The benthic mollusc assemblages, although sampled in Ionian Sea, showed a clear western species composition, in accordance with literature placing east of the Strait the bound- ary line between western and eastern Mediterranean eco-regions.
