Abstract

Three new species of Metrocoris, namely Metrocoris issaci sp. nov., Metrocoris josephi sp. nov. and Metrocoris latus sp. nov., are described from Meghalaya, India. Four new species groups are recognised in Metrocoris, namely the Metrocoris coxalis group, Metrocoris latus group, Metrocoris monticola group and Metrocoris nepalensis group. All except the M. latus group are erected from the M. compar group. Metrocoris issaci sp. nov. and M. josephi sp. nov. belong to the M. coxalis group and M. latus sp. nov. forms a monotypic group. Metrocoris issaci sp. nov. can be distinguished by the hind coxal process of female reaching half the length of hind trochanter; M. josephi sp. nov. can be distinguished by the medium-sized hind coxal process reaching only to the subbasal region of the hind trochanter and M. latus sp. nov. can be distinguished by the presence of broad parameres and conical pygophore of the male. Metrocoris dinendrai Basu, Polhemus & Subramanian, 2016, is synonymized with M. compar (White, 1883) and a redescription of M. compar is provided. Detailed illustrations of all the new species and M. compar are given.
