First report of acifer group of the subgenus Tripodura Townes (Diptera: Chironomidae: Polypedilum) from India, with a new species and updated world checklist.

A new species of the acifer group of the subgenus Tripodura and genus Polypedilum Kieffer is described on the basis of adult male. The acifer species group is recorded firstly from India. The molecular barcoding of the new species is provided.

Coriophagus chaudhuri sp. n. (Strepsiptera: Halictophagidae: Coriophaginae): a male strepsipteran from Jharkhand, India with a tentative phylogeny and world key to known males.

A new species of the genus Coriophagus Kinzelbach is described from the state of Jharkhand, India raising two in number from India. The new species, Coriophagus chaudhuri differs from other members of the genus in wing venation with base of R3 touching the subapex of R4, and flattened, oval-shaped foretarsomere I. The DNA barcoding of the new species has also been attempted here.

First records of three genera, Cyphomella Sther, 1977, Olecryptotendipes Zorina, 2007 and Robackia Sther, 1977 of the Harnischia complex from India with description of O. extentus sp. n., O. obtunsus sp. n. and R. aequilongia sp. n. (Diptera: Chironomidae).

Three genera, Cyphomella Sther, 1977, Olecryptotendipes Zorina, 2007 and Robackia Sther, 1977, of the Harnischia complex are recorded for the first time from India. Two new species of Olecryptotendipes and one new species of Robackia are described on the basis of adult males. Cyphomella camelus (Kieffer, 1955), described from Afrotropical and Palaearctic regions, is recorded for the first time from India and its description is supplemented.
