Critical Checklist of the Indian species of Hypogastrura (Collembola: Hypogastruridae) with a description of a new species from Satkosia Wild Life Sanctuary

: Ten Hypogastrura species have been found from India, two of which are described: H. unguiculata (Mitra, 1966) and H. satkosiaensis nov. sp. Two Indian species have been removed from Hypogastrura and have been included in the genus Ceratophysella based on their original descriptions: C. baltica (Tyagi Baijal, 1982) comb. nov. and C. katraensis (Tyagi Baijal, 1982) comb. nov. H. satkosiaensis sp. nov. belongs to H. manubrialis group of species within the genus and is easily separated from the other members of the group by a combination of characters, a greater number of antennal sensilla, dorsal chaetotaxy, specially presence of m1 chaeta on abdominal tergite V, and mucro shape. A key for all of the known Indian species of Hypogastrura is provided.
