The arboreal microsnail Insulipupa malayana (Issel, 1874) (Gastropoda: Stylommatophora: Vertiginidae) from West Bengal, India.

Studies on occurrence, host plant preference and morphometric features of the arboreal microsnail Insulipupa malayana (Issel, 1874) (Gastropoda: Stylommatophora: Vertiginidae) were carried out from selected sites of West Bengal, India. The snail species use the stem and bark of five plant species (Hibiscus rosa-sinensis, Mangifera indica, Aegle marmelos, Swietenia macrophylla, and Roseodendron donnell-smithii) as microhabitat, and the most preferred host plant was A. marmelos (Jacobs' selectivity index Dia= 0.5 ± 0.19). The mean ± SE values of shell height (SH), shell width (SW), aperture length (AL), aperture width (AW), body weight, apical angle (AA) and spire ratio (SR) of the collected specimens were measured as 1.95 ± 0.06 mm, 1.03 ± 0.01 mm, 0.54 ± 0.02 mm, 0.74 ± 0.02 mm, 0.86 ± 0.06 mg, 0.55 ± 0.02, and 1.89 ± 0.06, respectively. The present study will be informative to frame conservation strategies for I. malayana in India and elsewhere. [ABSTRACT FROM AUTHOR]
