The freshwater snail genus Sulcospira Troschel, 1858 is found in Sundaland, Indochina, and southern China, and its members usually occur in relatively fast running waters, such as rivers and streams or creeks (Köhler & Dames, 2009). Three species of Sulcospira have been recorded from Java: the type species of the genus, S. sulcospira (Mousson, 1848), as well as S. pisum (Brot, 1868) and S. testudinaria (von dem Busch, 1842) (van Benthem-Jutting, 1956; Köhler & Glaubrecht, 2005; Köhler et al., 2008). Earlier authors, including Morrison (1954) and van Benthem-Jutting (1956), referred the genus Sulcospira to the family Thiaridae and recognised only one species in Java, Sulcospira sulcospira.

Morrison (1954:381) stated that the shell of S. sulcospira appears to be similar to certain species of Brotia, Tylomelania, and to immature individuals of Balanocochlis. van Benthem-Jutting (1956) described the shell of S. sulcospira and cited Troschel’s (1858) remark that the animal of S. sulcospira contained numerous shelled juveniles, each with a shell of two whorls. Another species with a turreted but more slender shell than S. sulcospira is traditionally attributed to Brotia testudinaria (von dem Busch, 1842), while specimens with a broad shell shape and a short spire are identified as Balanocochlis pisum. These three species were placed in the family Thiaridae by van Benthem-Jutting (1956; see also Wenz, 1938; Morrison, 1954).

Pomacea canaliculata

The freshwater snails and have been reported as important invasive species causing damage to crops and predominantly wetland rice in Asia. These snails are known as “Golden Apple Snail” (GAS), an introduced species from Argentina. or known as “keong mas, keongmurbei” was introduced in Indonesia around 1983, and after more than 20 years, it now can be found very abundant at various habitats such as marshes, ponds, irrigations, lakes and rice fields in almost all places in Indonesia.

Based on the collections of these snails deposited in the MZB (Museum Zoologicum Bogoriense, Research Center for Biology) and secondary data (references), the distribution of these two snails was studied. is widely distributed, while is only found at Lake Semayang and Lake Balikpapan in Kalimantan. The distribution map is presented and will be useful as a basic information to manage these invasive snails. distribution, snail, invasive, Indonesia Pomacea canaliculata P. insularum Pomacea canaliculata Pomacea canaliculata P. insularum Pomacea canaliculata, P. insularum,

Jenis-jenis Sulcospira dari Jawa
Pendahuluan
Keong (Gastropoda) air tawar di pulau Jawa tercatat ada 62 jenis, menyebar dari Jawa Barat, Jawa Tengah hingga Jawa Timur (van Benthem Jutting, 1956). Namun hasil pemantauan dan ekspedisi yang dilakukan 20 tahun terakhir, saat ini tercatat ada 66 jenis, bertambah empat jenis yakni Pomacea canaliculata, Physastra stagnalis, P. sumatrana yang masuk ke Indonesia sekitar tahun 1980 an dan ditemukannya Sulcospira yang diduga jenis baru. Beberapa jenis keong menyebar luas di beberapa pulau lainnya, namun beberapa jenis lainnya terbatas hanya di Pulau Jawa atau endemik Jawa, seperti jenis-jenis Sulcospira sulcospira (Mousson, 1849) dan S. pisum (Brot, 1868). Keong air tawar umumnya dijumpai di berbagai tipe habitat seperti sungai, rawa, danau, kolam yang berair tenang atau berair deras, pada perairan dangkal atau dalam (> 10 m). Umumnya bersifat herbivore, namun beberapa juga karnivore, sebagian besar adalah pemakan detritus, lumut dan aneka ganggang. Beberapa jenis keong air tawar juga biasa dimakan, yakni keong tutut (Filopaludina spp.), keong gondang (Pila spp.) dan keong mas (Pomacea canaliculata), atau dikumpulkan sebagai pakan ternak itik dan lele.
