Main Article Content
We report the occurrence of the ant-mimicking jumping spider Myrmarachne melanocephala MacLeay, 1839 for the first time from Hazaribagh Wildlife Sanctuary, Jharkhand, India. Digital illustrations and descriptions of the spider, the female’s exuviae, and video records of a live male are also presented. The distribution pattern of M. melanocephala has not been studied in detail across India whereas its ant model, Tetraponera rufonigra Jerdon, 1851 is known to have a wide distribution. Co-occurrence of the mimic and the model implies a wider range of biogeographical distribution of these species in India.
