Objective: Cynodon dactylon, Hibiscus rosa-sinensis, Elaeocarpus floribundus and Acorus calamus are anthelmintic medicinal plants of north-east India. Due to its pharmacological properties, the present study was aimed to investigate the phytochemical, antioxidant and heavy metal content of the plants.Methods: Preliminary phytochemical screening was carried out for the presence of phenolics, flavonoids, proteins, and carbohydrates following standard protocols. The antioxidant potential of plants was studied by phosphomolybdate, 1,1-diphenyl-2-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assay. The heavy metal content was estimated using atomic absorption spectrophotometer (Perkin Elmer 3110). Results:The result showed that the alcoholic extracts of the plant sample contain high quantity of proteins, carbohydrates, phenolics, and flavonoids. Antioxidant assays revealed appreciable free radical scavenging potential. The total antioxidant activity was highest in E. floribundus (62.48±1.53 µg/mg extract) while C. dactylon showed lowest (34.00±0.32 µg/mg extract). Similarly, DPPH and FRAP study also showed high in E. floribundus and lowest in H. rosa-sinensis and A. calamus. Elemental analysis of the plant extracts showed a high content of Mn in all the plants while Co was found to be lowest. The tested plants showed low levels of toxic elements. Conclusion:The high quantity of nutritional content and antioxidant property suggest that plants may be a good source of phytomedicine. Less quantity of toxic elements offers an opportunity to explore the medicinal application of the plants. However, further study needs to be carried out to know its mode of action.

Goalpara was partitioned into Dhubri and Kokrajhar Districts and Jamduar fell under Kokrajhar District. The place is located in the eastern Raimona forest range, being part of the Ripu Reserve Forest under the Manas Biosphere Reserve [Forest Department, 2009]. This place is known for its magnificent scenic landscapes surrounded by Bhutan Hills harbouring diverse flora and fauna.The genus Asianopis consists of two species groups [Lin et al., 2020]: viz., the liukuensis-group and the zhuanghaoyuni-group, of which the former includes two nominal species -A. dumogae (Merian, 1911) and A. liukuensis (Yin, Griswold et Yan, 2002). D. goalparaensis belongs to this group, as it shares the following diagnostic characters thereof: proximally enlarged femora I; pear-shaped carapace; female chelicerae having four pro-and seven retromarignal teeth, with numerous denticles between them; epigyne with an anchor-shaped median plate; distinct copulatory openings; insemination ducts with three turns; and oval spermathecae [Lin et al., 2020].The present paper is aimed at the redescription of D. goalparaensis on the basis of newly collected material from the same district where the type locality lies. Detailed illustrations, a distributional map and notes on its natural history are provided. Materials and methodsSpecimens were hand collected during a night survey and photographed using a Sony Cyber-shot DSC-HX90V camera. The specimens were observed and photographed under a Leica EZ4 HD stereomicroscope enabled with a ABSTRACT: Asianopis goalparaensis (Tikader et Malhotra, 1978) comb.n. belonging to the liukuensis species group is redescribed on the basis of fresh specimens collected from Assam, India. Detailed illustrations, a distributional map and notes on its natural history are provided.

The genus Vailimia Kammerer, 2006 is recorded for the first time from India. Two new species, Vailimia ajmerensis Caleb & Jangid sp. nov. (♂), and V. jharbari Basumatary, Caleb & Das sp. nov. (♂♀), are described and illustrated in detail. Presently, the genus is known only by the males, which means that the female of V. jharbari described herein is the first female known in the genus.
