| Abstract | Male structures for clasping females during precopula interactions and mating (“claspers”) have evolved in many groups of arthropods. Several hypotheses regarding the function of claspers have been proposed. We describe how males of the true bug Stenomacra marginella (Heteroptera: Largidae) move their genital claspers during sexual interactions, and present the results of experiments in which we tested whether claspers are necessary to achieve intromission. When one and both claspers were partially amputated, the probability of successful intromission decreased from 62 to 0% and from 57 to 3%, respectively. Behavioral observations indicate that the claspers open the valves that cover the female genital opening. We consider the possibility that claspers in S. marginella may have multiple functions. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
