description: This dataset contains the digitized treatments in Plazi based on the original journal article Chand, D. Suresh, Das, Swapan Kumar, Kumar, Hirdesh (2022): Diversity of short and long-horned grasshoppers of Arunachal Pradesh, India. Records of the Zoological Survey of India 122 (1): 65-72, DOI: 10.26515/rzsi/v122/i1/2022/143670AbstractThe present study aimed to study the diversity of short-horned and long-horned grasshoppers of Arunachal Pradesh. Surveys were conducted from April 2009 to July 2010 at three different districts of Arunachal Pradesh, involving seven major localities. Thirty-two species of short-horned and long-horned grasshoppers have been recorded. Among the 32 species, 25 species are short-horned grasshoppers, while 7 species are long-horned grasshoppers. Overall the 32 species of grasshoppers come under 26 genera belonging to 11 subfamilies and spread over 3 families from the state of Arunachal Pradesh. The distribution of some species differed markedly from one site to another.Keywords: Caelifera, Ensifera, Himalaya, India, OrthopteraIntroductionArunachal Pradesh is an Indian state located in the North-Eastern part of India. It lies between 26.28° N and 29.30° N latitude and 91.20° E and 97.30° E longitude and has an area of 83,743 km 2. Biogeographically, it comes under the Indian Himalayan region. The order Orthoptera includes both short and long-horned grasshoppers and is represented by 29034 species globally (Cigliano et al., 2021). Of which 1166 species/subspecies belonging to 449 genera and 22 families are listed from India (Gupta & Chandra, 2019). As far as Arunachal Pradesh is considered, 164 species in 96 genera of 7 families were listed (Gupta & Chandra, 2018).Material and MethodsThe study was conducted from April 2009 to July 2010 at seven different localities of Arunachal Pradesh, coming under three districts, viz., Tawang, East Kameng and Lower Subansiri. The localities surveyed are depicted in the Map (Figure 1), which are Seijosa, Pakke Tiger Reserve, Ziro, Yazali, Surbhi village, Kitpli village and Jang. Collections for grasshoppers were done using standard sweep nets during the daytime in different ecosystems like grasslands, forest ecosystems, litters, near riverbeds, and agricultural ecosystems, bare ground, shrubs and soil crevices. Tettigonids were normally collected during the night time, however occasionally even during daytime the long-horned grasshoppers were available in the agricultural fields and other vegetation sites. In the nighttime, the collection was made using a light of 100 watts mercury vapour lamp displayed in front of white cloth (2x 2 meter), and those that were attracted towards the light were collected using handpick method. The insects thus collected from the field and light trap were killed in a killing jar, subsequently sundried and pinned. The collected specimens were studied with the help of a Stereo Zoom Binocular Microscope. All the material used in this work has been collected by D. S. Chand and party from different parts of Arunachal Pradesh and deposited in Orthoptera section of Zoological Survey of India, Kolkata.Systematic AccountOrder ORTHOPTERASuborder CAELIFERASuperfamily ACRIDOIDEAFamily ACRIDIDAESubfamily ACRIDINAETribe Acridini Macleay, 1821Genus Acrida Linnaeus, 1758
