New records of ant-mimicking spiders from North-East India

Spiders usually show Batesian mimicry with different model ant species. There are no specific study of ant mimicking spiders and their association with model ants from North-Eastern part of India. In this study, from the campus of Gauhati University, Assam, we recorded total eleven ant-mimicking spiders of which two are new records from India and seven are new records from North-East India. We noticed the model-mimic association of Myrmarachne melanocephala with Tetraponera rufonigra, Myrmarachne cornuta with Tetraponera allaborans, Myrmaplata plataleoides with Camponotus compressus, Myrmarachne acromegalis with Polyrhachis laevissima, Myrmaplata aureonigra with P. laevissima and Polyrhachis dives, Cambalida flavipes with Camponotus compressus and Apochinomma elongatum with Tetraponera nigra. Four unidentified Mymarachne sp. were found mimicking the ant species namely Camponotus parius, Technomyrmex albipes, Polyrhachis tibialis and Dolichoderus moggridgei. The work will open a new window for future studies to explore the ant’s and spider’s diversity and their co-evolutionary interactions for avoiding predator, deceive other individuals etc.
