Three species of digenean parasites, Pleurogenoides euphlycti, P. wayanadensis and Meharorchis ranarum of the frog Hoplobatrachus tigerinus (Anura, Dicroglossidae) from the Wayanad Region of the South Western Ghats are reported in this paper. Multiple infections were also recorded during the study. Prevalence of infection of P. euphlycti, P. wayanadensis and M. ranarum were 15.15%, 9.09% and 12.12%, respectively, and the intensity of infection were 5.2, 7.3 and 8, and the mean abundance were 0.78, 0.66 and 0.96, respectively. Mean abundance is an indication of the dispersion of parasites among hosts. The mean abundance and the intensity were at the maximum level in M. ranarum infection and that of prevalence of infection was at the maximum level in of P. euphlycti infection.

Phytosociological Study

Phytosociological study is the most essential in any community to know its structure and organization. The various qualitative characters obtained are used to determine the level of distribution, numerical strength and degree of dominance exhibited by the constituent species in the community. Thalictrum javanicum belongs to the family Ranunculaceae family, it is medium sized erect herb, found in the temperate Himalayas from Kasmir to Sikkim in Khasi hills, and Kodaikanal and Nilgiri hills of Western Ghats in Tamil Nadu, India. At global level, it is generally distributed in the hilly tracts of India, Srilanka, China and Java at the altitude of around 2400 m above msl. The present study was undertaken in Thottabetta , the Nilgiris by sampling using belt transects of 10x1000m size which further divided into 100 segments each which 10x10m size. The total number of species encountered in the study area is 45 which includes 5 grasses and 40 forbs. The quantitative ecological characters of the study species, T. javanicum is a detailed below: frequency 11%, abundance 3.82 individuals/m2, density 0.42 individuals/m2, basal cover 172.20/mm2/ m2, relative frequency 0.55% and relative density 0.08%, relative dominance 0.16%. Based on the ecological attributes it is determined that the species, T. javanicum is less perpetuated in the community studied. Hence, further studies on the determination of propagation strategies for population enhancement and conservationof wilds are suggested.

A New Species

A new species belonging to the subgenus Isonychia, of the genus Isonychia Eaton, 1871, is described based on larvae and imagoes collected from Moyar River, Nilgiri District, Tamil Nadu, India. The imagoes of I. moyarensis n. sp. can be distinguished from other described Oriental species of Isonychia (Isonychia) by the combination of characters: (i) forewing with rusty brown maculae in the costal, subcostal, and median areas; (ii) femur and tibia brown, fore leg pale, apices of tarsal segments brownish; (iii) males with distal angles of penes rounded, without serrations; (iv) second segment of gonostylus uniformly convex; and (v) sterna of tenth abdominal segment in female deeply cleft. Isonychia (Isonychia) moyarensis n. sp. can be distinguished in the larval stage from other known Oriental species by the following combination of characters: (i) abdominal terga II–IX with median dark brown maculae progressively larger with dark brown slanting streaks in lateral margins; (ii) trachea of abdominal gills I–VII unbranched; (iii) posterolateral projections on abdominal segments I–VII blunt and progressively longer than those of segments VIII–IX, sharp and distinct; and (iv) abdominal terga X pale yellow in anterior ⅓, and dark brown in the posterior ⅔. A key to the known larvae of Oriental species of Isonychia is also provided.

Amphibian diversity in the Western Ghats-Sri Lanka biodiversity hotspot is extremely high, especially for such a geo-graphically restricted area. Frogs in particular dominate these assemblages, and the family Rhacophoridae is chief among these, with hundreds of endemic species. These taxa continue to be described at a rapid pace, and several groups have recently been found to represent unique evolutionary clades at the genus level. Here, we report DNA sequences, larval and breeding data for two species of rhacophorid treefrog (Polypedates bijui and a new, hitherto undescribed species). Re-markably, they represent unique, independent clades which form successive sister groups to the Pseudophilautus (Sri Lan-ka) + Raorchestes (India, China & Indochina) clades. We place these species into two new genera (Beddomixalus gen. nov. and Mercurana gen. nov.). Both of these genera exhibit a distinct reproductive mode among Rhacophoridae of pen-insular India and Sri Lanka, with explosive breeding and semiterrestrial, unprotected, non-pigmented eggs oviposited in seasonal swamp pools, which hatch into exotrophic, free-living aquatic tadpoles. Relationships and representation of re-productive modes in sister taxa within the larger clade into which these novel genera are placed, is also discussed. These results suggest that more undescribed taxa may remain to be discovered in South Asia, and the crucial importance of con-serving remaining viable habitats.

The riparian Odonate insect diversity of the midstream Chalakudy River at six locations assessed from February 2018 to January 2019 has revealed the occurrence of 25 species of odonates. Among them,10 species are dragonflies belonging to seven genera of the family Libellulidae and the remaining 15 species are damselflies belonging to six families and 11 genera. Five endemic damselfly species have been recorded. Pseudagrion indicum is endemic to the Western Ghats, while the remaining four species, Vestalis apicalis, Libellago indica, Dysphaea ethela, and Heliocypha bisignata, are endemic to India. Diversity indices of the odonates in all the six locations were analyzed and it showed less abundance at sites where tourist activities are more and with thin native riparian vegetation. Further, the study has unequivocally revealed that thick native riparian vegetation is essential for their perching and existence. By and large, the uncontrolled tourism activities and habitat alteration interfere with the density and diversity of these endemic species.

Based on the examination of the type series of Cloe tristis Hagen, 1858 (type species of the genus Teloganodes Eaton, 1882) and material housed in several institutions, a revision of Oriental Teloganodidae is proposed. A lectotype is designated for Teloganodes tristis (Hagen, 1858) and the genus is redefined. The species T. major Eaton, 1884, is a subjective junior synonym of T. tristis Hagen, 1858 (syn. nov.). The genus Macafertiella Wang, 1996 is a subjective junior synonym of Teloganodes Eaton, 1882 (syn. nov.). A phylogenetic analysis is performed on all available nymphs. Teloganodes is restricted to Sri Lanka and the Western Ghats of India and encompasses the type species and T. dentatus Navás, 1931, T. insignis (Wang & McCafferty, 1996) (comb. nov.), and the following new species: T. tuberculatus sp. nov. (Sri Lanka), T. kodai sp. nov. (India), T. jacobusi sp. nov. (Sri Lanka) and T. hubbardi sp. nov. (Sri Lanka). The type material of T. dentata is redescribed. Species from Southeast Asia are assigned to two new genera. Dudgeodes gen. nov. includes the type species D. pescadori sp. nov. (Philippines) and D. lugens (Navás, 1933) comb. nov. (China), D. hutanis sp. nov. (Borneo), D. stephani sp. nov. (Borneo), D. ulmeri sp. nov. (Java, Sumatra), and D. celebensis sp. nov. (Sulawesi). The genus Derlethina gen. nov. is established for D. eloisae sp. nov. (Borneo). The egg morphology is presented for the first time for the family Teloganodidae. Affinities within the family and between related families are discussed and a key to distinguish all species known at the larval stage is proposed.

Myristicaceae Brown (1810: 399), the pantropical ‘nutmeg family’, comprise 21 genera and 520 species (Christenhusz & Byng 2016). The family thrives in the dense evergreen forests of the Western Ghats and is represented by three genera, viz. Gymnacranthera (Candolle 1855: 31) Warburg (1896: 94), Knema Loureiro (1790: 604) and Myristica Gronovius (1755: 141) (Nayar et al. 2014). Knema, one of the major genera of Myristicaceae with 93 species, is distributed in Indomalaya (Mabberley 2018). In India, the genus is represented by eight species, of which the endemic Knema attenuata (Wallich in Hooker & Thomson, 1855: 157) Warburg (1896: 590) is the only species in the Western Ghats (Sinclair 1961, Nayar et al. 2014, Banik & Bora 2016).
