We describe a new species of Cyrtodactylus from Guwahati city in the state of Assam, India and provide additional data on the recently described Cyrtodactylus guwahatiensis. Cyrtodactylus urbanus sp. nov. falls in the newly defined khasiensis group within the Indo-Burma clade of Cyrtodactylus and is the poorly supported sister taxon to Cyrtodactylus khasiensis. The new species differs from other members of the khasiensis group in mitochondrial sequence data (12.5–17.1 % uncorrected pairwise ND2 sequence divergence) as well as aspects of morphology including the number and arrangement of precloacal pores in males, the number of mid-ventral scales and paravertebral tubercles, and colour pattern. This is the second Cyrtodactylus endemic to the Guwahati region, the fourth from Assam and the twelfth from Northeast India.

Among various Naga communities of Northeast India, megalithic building and feasting activities played an integral role in the different and intertwined dimensions of social and political organisation until very recently. During a collaborative fieldwork in 2016, we visited different village communities in the southern areas of Nagaland and recorded local knowledge about the function and social implications of megalithic building activities. The preserved knowledge of the monuments themselves and their embeddedness in complex feasting activities and social structures illustrate the multifaceted character of megalithic building. The case study of Nagaland highlights how the construction of megalithic monuments may fulfil very different functions in societies characterised by institutionalised hierarchies than in those that have a more egalitarian social organisation. The case study of southern Naga communities not only shows the importance of various dimensions and courses of action–such as sharing and cooperation, competitive behaviour, and the influence of economic inequality–, but also the importance of social networks and different layers of kinship. The multifaceted and interwoven character of megalithic building activities in this ethnoarchaeological case study constitutes an expansion for the interpretation of archaeological case studies of monumentality.
