Abstract: Agriocnemis keralensis Peters, 1981 is reported for the first time from Maharashtra, India.  Previously it was known from Kerala and Goa states.  In this paper we report A. keralensis from Thakurwadi and Bambuli wetlands and Chipi Plateau, Sindhudurg District. Also, the new record of Gynacantha khasiaca MacLachlan, 1896 is confirmed on the basis of specimens collected from Sindhudurg District.  Hence, we report the range extension of both A. keralensis and G. khasiaca in northern Western Ghats.  Apart from this, a combined checklist of Odonata fauna of Thakurwadi (51 species), Bambuli wetlands (44 species), and Chipi Plateau (51 species) is provided.

 

Keywords: Agriocnemis, Anisoptera, Gynacantha, range extension, Sindhudurg, Western Ghats, Zygoptera.

 

 

India is one of the mega diverse countries of the world in terms of biodiversity.  Maharashtra, one of the biggest states in India, has 134 species of Odonata (Tiple & Koparde 2015).  Western Ghats as a whole harbours 174 Odonata species including 56 endemics (Subramanian & Sivaramakrishnan 2002; Subramanian et al. 2011), which increases the importance of habitat conservation. 

The narrow strip of land present between Arabian Sea and Western Ghats is known as the Konkan-Malabar region (Watve 2013).  Sindhudurg District is one of the biodiverse places situated in this region (Image 8c).  Recently, two new species of Odonata, namely, Ceriagrion chromothorax, Joshi & Sawant, 2019 and Bradinopyga konkanensis, Joshi & Sawant, 2020 have been described from Sindhudurg.  The district is situated in southern Konkan region covers a total of 5,207km2 of area and is bounded by the Arabian Sea on the west and the Western Ghats on the  east.  From the mountain streams of the Western Ghats, from perennial rivers to shallow wetlands on lateritic plateaus and large lakes in the district are ideal habitats for odonate species.

In this paper, we report the first record of Agriocnemis keralensis from Maharashtra, based on one male and one female specimen each, which is the northernmost record for the species and multiple field observations from nearby areas. Also, the presence of Gynacantha khasiaca in the Western Ghats is confirmed based on one male and one female specimen, which is the southernmost record for the species. These records are the range extensions for both the species. In addition to this, we provide a combined checklist of Thakurwadi and Bambuli wetlands and Chipi Plateau.

The present work was started in the year 2020 and carried out at three localities consisting of two wetlands and one plateau (see Table 1).  AD & YK first observed Agriocnemis keralensis at Thakurwadi on 20 July 2020 and subsequently from Bambuli wetlands and Chipi Plateau.  AD first observed Gynacantha khasiaca from Majgaon on 30 August 2020; 2 males and 1 female of A. keralensis were collected from Thakurwadi wetland and 1 male and 1 female of G. khasiaca were collected from Majgaon, Sawantwadi Taluka with the help of insect collecting nets.  Based on these specimens we report new records of the above mentioned species.  All specimens were preserved in 70% alcohol and three of them were deposited at Research Collections, National Centre for Biological Sciences (NCBS), Bengaluru, India and one specimen was deposited at Zoological Survey of India (ZSI), Western Regional Centre, Pune.  Collected specimens were examined and photographed under the Lawrence and Mayo microscope, model LM-52-3621 at Shivaji University, Kolhapur.  Field photographs of specimens were taken by Canon 760D with a 100mm macro lens and Nikon 7500D with Tamron 90mm lens.  Identification of the species was done with the help of standard field guides and Fauna of British India (Fraser 1936). Random survey method was applied to document odonate diversity in all above habitats.  Morphological terms refer to Garrison et al. (2006).  All measurements are given in mm.  Abbreviations in the text: FW= fore wing, HW= hind wing, Ax and Px= antenodal and postnodal nervures, Pt= pterostigma, S1–S10= abdominal segments 1–10.  Maps used in Image 8 were created using QGIS v3.14.

Diagnosis: Agriocnemis Seyls, 1869 genus has 11 species in India (Subramanian & Babu 2017).  From those species, Agriocnemis clauseni (Fraser, 1933), A. femina (Brauer, 1868), A. lacteola (Selys, 1877), A. kalinga (Nair & Subramanian, 2014), A. dabreui (Fraser, 1919) are reported from northeastern India (Nair & Subramanian 2014).  In fact, A. femina is also reported from the Western Ghats region (Subramanian et al. 2018).  A. pygmaea (Rambur, 1842) and A. pieris (Laidlaw, 1919), A. splendidissima (Laidlaw, 1919) are distributed throughout the Indian subcontinent (Kalkman, 2020) . A. keralensis is endemic to the Western Ghats (Kalkman 2020).  A. keralensis is identified by its small size, five post-ocular spots (one horizontal and two spots on either side), blackish-brown to brownish-orange abdomen with ‘cobra hood’ mark on S2.  This species is very similar to A. kalinga (Subramanian & Nair, 2014) with respect to cobra shaped hood mark on S2, but differs significantly in case of abdominal colouration.  A. pygmaea (Image 2b) which occurs with the same locality can be distinguished by the colour of the abdomen and absence of ‘cobra hood’ mark on S2.

Distribution (Image 8a,c): Agriocnemis keralensis was described by Peters in 1981 from Kerala and redescribed by Nair & Subramanian (2014).  Recently, it was reported from Goa State (Rangnekar et al. 2010).  In this paper, we report the northernmost record of A. keralensis from Thakurwadi, Bambuli, and Chipi, which is range extension for the species (Image 8c).  A population of A. keralensis with good number of males and two females with one heteromorph were observed at Thakrwadi wetland.  A total of four individuals were observed at Bambuli wetland.  Chipi Plateau had scattered colonies in seasonal ponds with both males and females.  No females were observed at Bambuli.

Habitat (Image 7a,b,c): Thakurwadi wetland is a perennial waterbody where many males and two females including heteromorph female of Agriocnemis keralensis were found.  Individuals were observed in the aquatic grasses.  Other species observed were Agriocnemis pygmaea, Urothemis signata, and Ceriagrion spp.  Bambuli wetland, a perennial waterbody where four males of A. keralensis were found in aquatic grasses.  Scattered population was found on lateritic plateau of Chipi in seasonal ponds.

Caudal Appendages (Image 5b,c).  Black, cerci pointed almost as long as S9, ovipositor dark brown.

Measurements: Abdomen including caudal appendages= 55, FW= 44, HW= 45.

Diagnosis: Gynacantha Rambur, 1842 is a genus of large sized dragonflies with 99 species distributed throughout the world (Paulson & Schorr 2020).  Among them 14 species are reported in India (Kalkman et al. 2020).  G. khasiaca was previously recorded from Assam (Laidlaw 1923; Fraser 1936), Meghalaya (Fraser 1922; Kimmins, 1969; MacLachlan 1896) and West Bengal (Mitra 2002).  In this paper, we report new locality of G. khasiaca in northern Western Ghats which is an extension in range for the species.  Here we report first confirmatory record in Maharashtra State and entire Western Ghats.  ‘T’ shape mark on postfrons, sharply defined brown stripes on each side of pterothorax, long and pointed cerci, paraprocts almost two-thirds length of cerci are helpful to distinguish it from other species of Gynacantha genus.  Gynacantha cattienensis Kompier & Holden, 2017 is similar to G. khasiaca, but previous species is present in Vietnam and can be distinguished from later by the absence of thoracic stripes, different shape of auricle and cerci.

Distribution (Image 8b,c): Gynacantha khasiaca is previously known from India, Bangladesh, Bhutan, and Nepal.  In India, it was recorded from northeastern states, i.e., Arunachal Pradesh, Assam, Meghalaya, West Bengal, and coastal areas of West Bengal.  In October 2019, Gynacantha cf. khasiaca was reported from Thakurwadi wetland, Sindhudurg District, Maharashtra on the basis of photograph of a male (Mujumdar et al. 2020) (Image 6d).  With this record, now G. khasiaca is reported from two localities from northern Western Ghats.  This record is the southernmost range of the species in India.

Habitat (Image 7d): Two males and one female of Gynacantha khasiaca were observed at Majgaon Village, Sindhudurg District.  All the individuals were attracted to light and came in house of AD in the night time.  The place has human population surrounded by trees and seasonal natural streams at close proximity.

 

Result and Discussion

After multiple surveys in Thakurwadi and Bambuli wetlands and Chipi Plateau, we recorded a total of 65 species of odonates, consisting of five families of Zygoptera and four families of Anisoptera (Table 2).  Family Coenagrionidae in Zygoptera and family Libellulidae in Anisoptera had the maximum number of species at all three locations (Table 2; Figure 1).  Thakurwadi wetland  was recorded with the maximum number of species (57 species) with a special mention of Ceriagrion chromothorax, Pseudagrion malabaricum, and Indothemis limbata, apart from Agriocnemis keralensis and Gynacantha khasiaca (Image 9).  Chipi Plateau (51 species) and Bambuli wetland (44 species) also had a good number of diversity in terms of species.  Out of 65 species, Agriocnemis keralensis, Ceriagrion chromothorax, and Bradinopyga konkanensis are endemic to the Western Ghats (Table 3).  Out of 65 species, 57 are LC (Least Concern), three are DD (Data deficient), and five are NE (Not Evaluated) as per IUCN status.

We report Agriocnmeis keralensis for the first time from Maharashtra and confirm record of Gynacantha khasiaca from Maharashtra.  Three localities of A. keralensis in Sindhudurg are the northernmost record of the species which was previously known from Kerala and Goa (Image 8a).  Out of the three localities, Thakurwadi and Bambuli are wetlands with moderate human interference.  These two are major water sources to nearby human habitation in terms of farming.  Third locality, Chipi plateau is a lateritic plateau near Arabian Sea and has many seasonal ponds. G. khasiaca was photographed in Sindhudurg District in October 2019 (Mujumdar et al. 2020) but further confirmation was not done due to lack of specimens.  With this record from Majgaon, we confirm the presence of G. khasiaca in northern Western Ghats and report the range extension for the same (Image 8b).  Majgaon is a village in Sawantwadi Taluka, surrounded by dense vegetation and some seasonal streams.  With all these records, the rich biodiversity of Sindhudurg District is again highlighted.  Yet there are many remote and inaccessible locations in the district, which may reveal new records in terms of biodiversity.  Hence, systematic surveys of such areas should be conducted for documentation of biodiversity so that long term measures for conserving the habitats can be taken effectively.

Sindhudurg District is one of the richest biodiversity hotspots in India.  But there are many threats to the environment due to manmade activities.  Rampant deforestation in the foothills of the Sahyadri range, monoculture farming, raw mining on lateritic plateaus, excessive sand mining in river beds are major threats which are causing habitat destruction.  Wetlands like Thakurwadi and Bambuli are rich in terms of not only Odonata fauna but also other organisms.  There is an immediate need to conserve such wetlands and other water bodies for long term benefits to humans and other organisms.  Plateaus like Chipi are unique lateritic plateaus and are facing habitat disturbances due to raw mining, constructions of houses, and roads.  The current checklist of Odonata from these localities shows the richness of biodiversity and highlights the need for effective conservation measures.
