Abstract The study examined the individual ants identification in the Periyanaickenpalayam village, Coimbatore District, Tamil Nadu, as there is no adequate information pertaining on ant diversity of this region. The present study was carried out during NOV 2018 to JUN 2019. We have sampled ants by employing intensive all out search method. The sampled specimens representing 32 species belonged to five subfamilies. The most diverse subfamily was Formicinae (4 genera with 16 species) and Myrmicinae (5 genera with 12 species).The smallest number of species belonged to the Ponerinae (1 genus with 1 species). Every species individual parts were identified colour, stiner, antennae, spines and thorax were observed. Key words: Ants, Individual, Identification Introduction In India, a few reports on ant ecology Ants diversity exit [1]. A significant focus for present-day myrmecologists is the assessment of biodiversity, community composition, biogeography, and other basic investigations of the ecology of a regional ant biota. The Myrmicinae is the largest subfamily of the Formicinae. With 138 genera followed by Formicinae that have 39 genera and Ponerinae which have 25 genera [2]. Ants are ubiquitous in distribution and occupy almost all terrestrial ecosystems. There are about 15000 species of ants [3]; only 11,769 species have been described [4]. This family is included in the In India, a few reports on Ant ecology and diversity superfamily Vesipedae of the order Hymenoptera, exist. Work on ants of which is placed in the class Insect. The Myrmicinae is the Western Ghats - SriLanka hotspot. The largest subfamily of the Formicinae, with 138 genera, reported the ant fauna from some areas of Bangalore City. ``There are more species of ants in a square kilometre of Brazilian forest than all the species of Volume 9 Issue 7 - 2019 323 www.joics.org Journal of Information and Computational Science ISSN: 1548-7741 primates in the world, more workers in a single colony of driver ants than all the lions and elephants in Africa'' [5]. Materials and Methods Study area The field work was conducted in the Periyanaickenpalayam village, Coimbatore district, Tamil Nadu. Coimbatore lies at 11°1′6″N, 76°58′21″E, in south India at 411 metres (1349 ft) above sea level on the banks of the Noyil River, in south western Tamil Nadu. The average annual rainfall is around 700 mm (27.6 in) with the northeast and the southwest monsoons contributing to 47% and 28% respectively to the total rainfall. Periyanaickenpalayam is a neighbourhood in Coimbatore in the Indian state of Tamil Nadu. It is located along National Highway NH 67, Mettupalayam road, an arterial road in Coimbatore. Collection Method We employed all out search method for the collection of ants in NOV 2018 to JUN 2019. Ants were collected using a brush and forceps during day time in between 11am to 4 pm twice in every month. Every ant individually identified.

During this study a total of 32 ant species are belonging to Volume 9 Issue 7 - 2019 326 www.joics.org Journal of Information and Computational Science ISSN: 1548-7741 five subfamilies. Subfamily Formicinae were represented by 12 species and 4 genera followed by Myrmicinae were 12 species and 5 genera, Subfamily Pseudomyrmicinae consists of 5 species and 1 genus, Ponerinae consisits of 1 genera and 1 species and Doilchoderinae represented by 2 species and 1 genus. The most number of genus was Camponotus with 9 species were identified. In every ant species size, colour, thorax, antennae and stinger were observed. In the present study, were recorded 32 species of ants in 13 genera representing five subfamilies namely Formicinae, Myrmicinae, Ponerinae, Dolichoderinae
