Platysternidae (1), Trionychinae (16), Geoemydidae (53), Testudinidae (7) of Testudines Order <strong>(Buhlmann <em>et al<\/em>., 2009). <\/strong>The family Geoemydidae comprises of highly endangered species of Southeast Asia <strong>(<\/strong><strong>Baruah, 2016)<\/strong><strong>. <\/strong>India has one of the most diverse turtle fauna with 28 species, ranked among top five countries in terms of turtle conservation in Asia and the world <strong>(Buhlmann, 2009). Moll (1987) <\/strong>has reported <em>P. tecta<\/em>, which is moderately common on along the banks of Narmada River of Gujarat. The previously published literature mainly focuses on the breeding of the Indian Roofed Turtle in captivity from Gujarat <strong>(Vyas, 2001)<\/strong>.<\/p>\n<p><strong><em>Pangshura tecta <\/em><\/strong><strong>(Gray, 1831)<\/strong><\/p>\n<p>The genus <em>Pangshura<\/em> comprises of small-sized turtles. India hosts six species of <em>Pangshura<\/em> genus. <em>P. dhongoka, P. kachuga, P. smithi, P. sylhetensis, P. tecta, and P. Tentoria <\/em><strong>(Tikader, 1985). <\/strong>The Indian Roofed Turtle (<em>Pangshura tecta<\/em>,Gray, 1831) is the freshwater turtle belonging to the family Geoemydidae of the order\u00ad\u00ad\u00ad\u00ad\u00ad\u00ad\u00ad\u00ad\u00ad\u00ad\u00ad\u00ad Testudines. <em>P. tecta<\/em> is one of the 17 freshwater turtle species found in India <strong>(Tikader, 1985). <\/strong>It is one of the poorly known Indian turtles <strong>(Vyas, 2001)<\/strong>. The entire population of this species is under abiotic and biotic constraints, and is rapidly decreasing in the wild <strong>(Vyas, 2001).<\/strong><\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<h3><span style=\"color: #000080;\"><strong>DISTRIBUTION<\/strong><\/span><\/h3>\n<p>This species has been reported from India, Pakistan, Nepal, and Bangladesh <strong>(Das, 1995)<\/strong>. It has a wide range in northern India, in the drainages of the Indus, the Ganges, the Brahmaputra and the Sind river systems of India and Pakistan <strong>(Smith, 1930)<\/strong>. In the previous study <strong>(Basumatary, 2013)<\/strong>, <em>P. tecta<\/em> was observed very rarely in Brahmaputra as well as Diffolu river in Kaziranga NP, Assam. It is also found in the Pleistocene deposits of Shiwalik Hills in the fossil form <strong>(Tilak and Sinha, 1984)<\/strong>. They have also reported the occurrence of the same species in the Terai region of Uttar Pradesh, India. <strong>Hall (1980)<\/strong> has recorded the species along the Nepal-Bihar border. <em>P. tecta<\/em> has also been reported in larger freshwater bodies of Gujarat e.g. Narmada River, Gujarat <strong>(ZSI, 2000)<\/strong>. <strong>Moll (1987)<\/strong> found it to be moderately common among all other reported specie of turtles from various biotic provinces of India.<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<h3><span style=\"color: #000080;\"><strong>HABITAT<\/strong><\/span><\/h3>\n<p>Slow-moving rivers and stagnant water bodies like ponds, puddles, tanks, roadside ditches, and nullahs are habitat to this omnivorous species (<em>P. tecta<\/em>). Basking on banks, logs, or aquatic vegetation is common for this species. The species is generally observed to avoid locations that have been disturbed by humans. During the winter, the female individual of the species lays 4-10 eggs each per clutch on sandy banks. It feeds on aquatic plants <strong>(Ahmed, 2010). <\/strong>Generally, the species is found in freshwater rivers and stagnant water bodies. However, it is also found occasionally in salt-water habitats <strong>(Hossain, 1995). Das (1991) <\/strong>has also published one record of Indian Roofed Turtle from the estuarine environment of Sundarbans delta. Its occurrence in saltwater might be due to devastating cyclone in Sundarbans or the decreasing salinity of Arbesi river, West Bengal.<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<h3><span style=\"color: #000080;\"><strong>IDENTIFICATION<\/strong><\/span><\/h3>\n<p><em>P. tecta<\/em> can be distinguished by the presence of a distinct &#8220;roof&#8221; at the topmost part of the shell. Identification marks includes fine yellow longitudinal stripes on the neck, red or orange crescent marking near eyes. Carapace is elevated with flat sides and a strong median keel. The head is moderately small, pointed, and shorter than the orbit. The hexagonal neural plates are short-sided in front. The plastron is united with carapace by sutures. The axillary and inguinal buttresses are extensively developed, extending nearly to the neural plates, the former connected with the first rib. The fourth vertebral shield is elongated, much longer than broad and much longer than the third one. It has more or less flattened limbs with webbed digits, and forelimbs bear five claws having yellow spots in line. Top of the head is covered with smooth skin. Males are the smaller of the sexes and possess a comparatively longer tail that is thicker at the base. Males of the species possess white bands on top of the tails, while females possess yellow bands. In addition, male carapaces are darker and the irises are red as opposed to the paler carapaces and pink irises of the females.<\/p>\n<p>&nbsp;<\/p>\n<h3><span style=\"color: #000080;\"><strong>THREATS<\/strong><\/span><\/h3>\n<p>In the Indian State of Uttar Pradesh, certain tribal communities settled in the Terai region were found to practise a huge turtle kill, putting the creature&#8217;s existence in danger <strong>(Tilak and Sinha, 1984)<\/strong>.<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<h3><span style=\"color: #000080;\"><strong>CONSERVATION STATUS<\/strong><\/span><\/h3>\n<p>The Indian Roofed Turtle is Protected under WPA 1972 and placed in Schedule-I <strong>(Ahmed, 2010)<\/strong>. International Union for Conservation of Nature (IUCN) has declared as Vulnerable species <strong>(Ahmed, 2010). <\/strong>It is also included in appendix I of Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which is list of species that are the most endangered among CITES-listed animals and plants <strong>(Ahmed, 2010).<\/strong>This is a relatively widespread species but local consumption reported. Population is also regarded as in a declining trend <strong>(Ahmed, 2010).<\/strong><\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<h3><span style=\"color: #000080;\"><strong>SITE DESCRIPTION<\/strong><\/span><\/h3>\n<p>Kanewal Community Reservoir (KCR) is an internationally important wetland, listed in Directory of Asian Wetlands <strong>(Scott, 1989)<\/strong>; designated as a \u2018Wetland of National Importance\u2019, and a proposed community reserve of Gujarat State, India.

As the individual was a bit inactive, we picked it up in our hands, and snapped few photographs for confirmation of its identity. Later on, the individual was released back safely in its natural aquatic habitat, not to be harmed by natural or anthropogenic stress. After referring standard published literature <strong>(Tikader and Sharma, 1985; Daniel, 2002)<\/strong>, the species was identified as Indian Roofed Turtle (<em>Pangshura tecta<\/em>, Gray, 1831). The species is aquatic and inhabits freshwater bodies with plenty of aquatic vegetation. It is a less active species and comparatively a poor swimmer <strong>(Tikader, 1985). <\/strong>The abundant aquatic plant species such as <em>Marselia quadrifolia, Hydrilla verticillata, Nelumbo nucifera<\/em> and plenteous beds of <em>Typha angustata<\/em> creates a suitable habitat for the Indian Roofed Turtle.<\/p>\n<p>&nbsp;<\/p>\n<h3><span style=\"color: #000080;\"><strong>SIGNIFICANCE OF THE RECORD<\/strong><\/span><\/h3>\n<p>In the past, some researchers have worked only on the breeding of the Indian Roofed Turtle in its captivity in Gujarat <strong>(Vyas, 2001)<\/strong>. In addition, previous published literature did not reveal the occurrence of this species in its natural habitat in Gujarat since last 32 years. Therefore, as there is lack of any such published record on the occurrence of the Indian Roofed Turtle (<em>P. tecta<\/em>) in its natural aquatic habitat in Gujarat, the findings of the observed species may be treated as \u2018<em>Unusual or Infrequent Occurrence<\/em>\u2019 or \u2018<em>Probable First Record<\/em>\u2019 in Gujarat, India.<\/p>\n<p><img \/><a href=\"http:\/\/www.indiawilds.com\/diary\/wp-content\/images\/\/Roofturtle.png\"><img loading=\"lazy\" class=\"aligncenter wp-image-9379\" src=\"http:\/\/www.indiawilds.com\/diary\/wp-content\/images\/\/Roofturtle.png\" alt=\"\" width=\"650\" height=\"359\" srcset=\"https:\/\/www.indiawilds.com\/diary\/wp-content\/images\/Roofturtle.png 1334w, https:\/\/www.indiawilds.com\/diary\/wp-content\/images\/Roofturtle-300x166.png 300w, https:\/\/www.indiawilds.com\/diary\/wp-content\/images\/Roofturtle-1024x565.png 1024w, https:\/\/www.indiawilds.com\/diary\/wp-content\/images\/Roofturtle-768x424.png 768w\" sizes=\"(max-width: 650px) 100vw, 650px\" \/><\/a><\/p>\n<p style=\"text-align: center;\"><strong>Figure <\/strong><strong>2<\/strong><strong>. <\/strong><strong>Pangshura tecta<\/strong><strong> (Gray, 1831) at Kanewal Community Reservoir (KCR)<\/strong><\/p>\n<h3><span style=\"color: #000080;\"><strong>REFERENCES<\/strong><\/span><\/h3>\n<p>Ahmed, M.F. and Das, A.
