Abstract Cosmocerca bengalensis sp. nov. (Ascaridida, Cosmocercidae) recovered from the rectum of an Indian bullfrog, Hoplobatrachus tigerinus (Daudin, 1803), collected from Hetampur town in Birbhum district of West Bengal, India, is described and illustrated. This species is similar to C. acanthurum, C. banyulensis, C. cruzi, C. japonica, C. kalesari, C. microhylae, C. novaeguineae, C. ornata, C. paraguayensis, C. parva, C. podicipinus and C. travassosi in having 5 pairs of plectanes supporting preanal papillae but differs from these species by general morphometry, absence of somatic papillae in females, absence of gubernaculum and having only one pair of adanal papillae in males and one pair postanal papillae in females except C. microhylae. Present parasites differ from C. microhylae by absence of gubernaculum and general morphometry. Cosmocerca bengalensis sp. nov. represents the thirtheith species assigned to the genus, seventh from Oriental region and fifth species from India.

Radical Conversion

Degradation of lateritic environment as found in the south western and eastern Birbhum district can be considered as irresistible. Inherently poor physical and chemical status of existing lateritic soil profile and radical conversion of land uses as observed at cadastral level are the key factors of land degradation. Lateritic soilscapes are mostly affected by water erosion induced, vegetal and anthropogenic degradation attaining severe and very severe degradation status. Degraded lands in sample mouzas like Ballabhpur, Shyambati, Chawpahari Jungle, Bodakuri and Pachami account for 60.33%, 71.42%, 72.99%, 87.31% and 79.66% respectively out of their total lateritic exposures. In other words about 36.98%, 71.42%, 61.73%, 56.70% and 76.02% out of their total village areas and mostly non agricultural land use are affected by it. Four degraded villages get the higher priority for friendly landscape conservation actions.

Aplectana hoplobatrachusia sp. nov., recovered from the rectum of Jordon’s bullfrog, Hoplobatrachus crassus, (Jerdon, 1853) collected from Lohagram in the Birbhum district of West Bengal, India, is described and illustrated. This species is characterised by absence of a gubernaculum and differs from other species of Aplectana which lack a gubernaculum (viz. A. akhrami, A. artigasi, A. chilensis, A. crossodactyli, A. crucifer, A. delirae, A. dubrajpuri, A. meridionalis, A. papillifera, A. praeputialis, A. tarija and A. vercammeni) by morpho-metrical ranges of males and females and number and distribution of caudal papillae in males which include 4 pairs preanal, 1–2 pairs adanal, 10 pairs postanal and a single median papilla on the upper lip of the cloaca. Aplectana hoplobatrachusia sp. nov. represents the 56th species assigned to the genus and the 4th from India and the 5th from Indian subcontinent.
