Two new species and two new records of Onychiurinae (Collembola, Onychiuridae) from the Nilgiris, India.

Four species of Onychiurinae are reported from the Nilgiris, Western Ghats, southern India, including two new species, Thalassaphorura udagaiensis sp. nov. and Protaphorura sholai sp. nov., and two new records for India: Protaphorura fimata (Gisin, 1952) and Orthonychiurus folsomi (Schffer, 1900). Thalassaphorura udagaiensis sp. nov. can be separated easily from the similar species T. encarpata by the presence of 10/011/221110 dorsal S-chaetae and shorter anal spines. Protaphorura sholai sp. nov. is the most similar to the species P. microtica, P. subarctica and P. levantina as having the same number of ventral pseudocelli and parapseudocelli on abdomen; it can be easily distinguished by the position of head chaeta p2 in relation to p1 and p3, shorter M and Sp chaetae on Abd V and longer anal spines. We also sequenced the mitochondrial barcode region of cytochrome oxidase I (658 base pairs) to confirm the species status.

On two new species of the genus Ctenolepisma (Zygentoma: Lepismatidae) from India.

Two new species of the genus Ctenolepisma Escherich, 1905 are described from Andhra Pradesh and Tamil Nadu, India: Ctenolepisma (Ctenolepisma) venkataramani sp. n. and Ctenolepisma (Ctenolepisma) udumalpetense sp. n. Their affinities with related species are discussed and a key to the Indian species of the genus is provided.

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.
