A NEW GENUS AND SPECIES OF PLANORBIDAE (GASTROPODA: HETEROBRANCHIA: PULMONATA) FROM NORTHERN AUSTRALIA

A new genus and species of Planorbidae, Kessneria papillosa n.gen.and sp. from the Northern Territory, Australia, are described.The new genus is morphologically most similar to Leichhardtia,another genus restricted to Northern Australia, from which itdiffers in a number of important shell and anatomical characters.The shell of the new genus differs from all other planorbidsin having a raised, papillate protoconch, and is also uniqueamongst Australian high-spired genera in being umbilicate and inhaving a sinuate outer lip.

DISTRIBUTION OF THE SCHISTOSOME VECTOR SNAIL, BIOMPHALARIA STRAMINEA (PULMONATA: PLANORBIDAE) IN HONG KONG

Biomphalaria straminea (Dunker) is a snail intermediate hostof Schistosoma mansoni Sambon which has invaded Hong Kong inrecent years from its home range in Brazil. This study examinesits distribution pattern in terms of habitat type and hydrologicalfactors. The data revealed very strong colonizing power, bothin terms of number of sites occupied as well as numerical dominanceat these sites. An inability to colonize lotic habitats mayhave been related to low levels of dissolved minerals and nutrientsbut the effect of current speed on colonization has yet to beresolved. Principal component analysis revealed that hydrological factorsimportant for colonization included high levels of dissolvedcalcium, magnesium, iron, chloride, total nitrogen, sulphateand phosphate. pH had only a secondary effect. The significanceof these findings is discussed with special reference to thelikelihood of introduction of B. straminea elsewhere, and possiblemanagement strategies.

OBSERVATIONS ON SHELL MORPHOLOGY, ENZYMES AND RANDOM AMPLIFIED POLYMORPHIC DNA (RAPD) IN BULINUS AFRICANUS GROUP SNAILS (GASTROPODA: PLANORBIDAE) IN ZANZIBAR

The taxonomic status of Bulinus globosus and B. nasutus as separatespecies remains unclear, espécially in areas of EastAfrica where their distribution overlaps. In order to throwfurther light on this question, a study was carried out on snailscollected from the islands Unguja and Pemba, collectively knownas Zanzibar, which lie in the Indian Ocean close to mainlandAfrica. In total, 169 snails from 22 sample sites were characterisedby three methods: morphometric analysis of 15 shell measurements,enzyme analysis involving three enzyme systems and analysiswith random amplified polymorphic DNA (RAPD). Enzyme analysesindicated that both B. nasutus and B. globosus were presenton each island and their distribution was allopatric. Shellvariation was considerable but did not clearly differentiatethese taxa. Similarly, RAPD analysis indicated substantial geneticvariation with in and between samples; more often than not,no two RAPD profiles were identical within the sample. On Pemba,B. globosus is more widely dispersed than B. nasutus which isconfined to the eastern coast of the central region. On Unguja,B. globosus is found in more northern areas than B. nasutus.
