A new cosmocercid nematode species, Cosmocerca asansolensis sp. nov. (Ascaridida, Cosmocercidae) is described from an Indian bullfrog, Hoplobatrachus crassus (Jerdon, 1853), from Asansol town, Paschim Bardhaman district, West Bengal, India. This species is characterized by the presence of five pairs of plectanes supporting preanal papillae, absence of somatic papillae in females, and having one pair large postanal papillae, a single papilla on the upper lip of cloaca, a single papilla on the lower lip of cloaca and one pair adanal papillae in males and one pair postanal papillae in females. Spicules of the present species are equal, moderately sclerotized, knobbed and wide proximal end gradually tapering to a fine point distally. The gubernaculum is well sclerotized and Y-shaped. Cosmocerca asansolensis sp. nov. represents the 33rd species assigned to the genus, 8th from Oriental region and 6th species from India.

The dynamics of land use/land cover (LULC) changes, the effect of coal mining on the LULC changes, and the regional environmental impact are discussed in this study. The different land use classes mainly Forest, Water Bodies, Road, Mining Area, Agriculture and Grass in the study area of V. D. Yalevsky coal field area in Prokorvisk city in Kamerovo region of Russia are identified. On the other hand the impact of V. D. Yalevsky coal mine activities on LULC change on the environment and teritory are discussed. The LULC changes in the V. D. Yalevsky coal field area were analyzed for a period of 27 years e.g., from the year 1992 to 2019. The changes were detected on a 13-years time interval using Landsat-4 TM, Landsat-8 OLI. Furthermore supervised classification techniques using maximum likelihood method through ENVI (Environment for Visualizing Images) 5.1software was utilized. In addition post classification change detection method through ENVI was used to investigate the changes. The study reveals decrecment in LULC cotogories of forest to 25.35km², water bodies to -0.94km², agriculture to -98.48km², road to -10.80km². However increment in the rate of mining area to 100.72km² and grass cover 34.86 km² during the study period. Meanwhile 90.18% overall accuracy and (0.87) kappa coefitient for 1992 classified image, 93.41% overall accuracy and (0.91) Kappa koefitient for 2006 classified image and 88.69% overall accuracy and (0.85) kappa coefitient for 2019 classified image were obtained.

From the Asansol region of district Paschim Bardhaman of West Bengal, India two parasitic nematodes belonging to same genus, Tanqua tiara from the stomach of Water monitor lizard, Varanus flavescens and Tanqua anomala from the intesine of Asiatic water snake, Xenochropis piscator were recovered. The Surface structures of head region of both nematodes have been examined with Scanning electron microscope. The mouth region of both species is characterised by presence of two large pseudolabia followed by cephalic bulb. Each pseudolabium bears a pair of submedian cephalic papillae and a lateral amphid. T. tiara has four large cephalic bulbs whereas T. anomala has two large cephalic bulbs. Asansol industrial region is recorded as new geographical area for this parasite.
