Haryana is primarily an agrarian state. The existing studies of earthworm diversity in Haryana are restricted mostly to the trans-Gangetic plains of eastern Haryana. To explore the diversity in central Haryana, the present study was conducted at six different sites of Tehsil Gohana of District Sonipat in Haryana, India. A total of eight species belonging to three different families were recorded from six different sites. Metaphire posthuma, Metaphire planta, Lampito mauritii and Perionyx excavatus belong to the family Megascolecidae. Three species viz., Eutyphoeus orientalis, Eutyphoeus incommodus, and Octochaetona beatrix, belong to the family Octochaetidae and Pontoscolex corethrurus belongs to the family Glossoscolecidae. Pontoscolex corethrurus, Perionynx excavitus and Eutyphoeus orientalis are the first record. Present findings reveal the first record of three species, namely, Pontoscolex corethrurus, Perionynx excavitus and Eutyphoeus orientalis, belonging to the family Glossoscolecidae, Megascolecidae and Octochaetidae, respectively.

The Deccan plateau spans nine states: Telangana, Andhra Pradesh, Tamil Nadu, Kerala, Karnataka, and Maharashtra. The Chotonagpur plateau includes parts of Chhattisgarh, central Jharkhand, and Meghalaya (Garo, Khasi and Jaintia Hills). We had the opportunity to collect and record some Chotonagpur plateau leeches. Only two species, Hemiclepsis chharwardamensis Mandal, 2013 and Paraclepsis jorapariensis Mandal, 2015, had previously been recorded from Chotonagpur and central Jharkhand. In the recently collected leech fauna of India's Deccan Plateau, five species belonging to two genera and two families, Poecilobdellidae and Glossiphonidae, were found in various habitats. Poecilobdella manilensis Lesson, 1924, Poecilobdella granulosa (Sevigny, 1826), and Hemiclepsis marginata marginata Müller, 1774 are three foreign species and Hemiclepsis marginata asiatica Moore, 1924 and Poecilobdella aligarhensis Mandal et al., 2021 are indigenous to India. More surveys are needed in the Deccan Plateau, which could lead to the discovery of additional species. [ABSTRACT FROM AUTHOR]

Earthworms are natural tillers of the soil and are known as the farmer's friends. The earthworm physiology is capable of combating pollution and pathogens and is therefore worth exploring. Although effect of pollution on earthworm immune system is being studied, elemental analysis of earthworm is not studied, how pollution affects the elements in earthworms, is not known. New species of earthworm was recorded from the state of Orissa, India. In this study we have tried to understand the elemental composition in a new species of earthworm, Perionyx shyamasreetus (P shyamasreetus) isolated and reported earlier, from the soil of Institute of Physics (IOP) campus, Bhubaneswar, Orissa India. We have performed fluorescence spectrophometry, UV-Vis studies, The Fourier-transform infrared (FTIR) and Proton induced Xray Emission (PIXE) studies on earthworm from the wild to understand the elements that exists in it. We observed that the elements including Sulphur (S), Chlorine (Cl), Potassium (K), Calcium (Ca), Titanium (Ti), Vanadium (V), Iron (Fe), Zinc (Zn), Copper (Cu), Chromium (Cr)are present from the PIXE studies on the tissues of earthworm as trace elements and Fe as minor element while Carbon (C), Hydrogen (H), Nitrogen (N) and S as major element. FTIR spectroscopy and UVVis fluorescence studies reveal the presence of amino acids such as tryptophan, tyrosine and cysteine. The future scope of the study lies in understanding the elemental composition of earthworm in environmentally toxic soils including radioactivity prone areas of Orissa. [ABSTRACT FROM AUTHOR]
