Two Emesinae bugs, namely Stenolemus crassirostris Stål, 1871, and Gardena brevicollis Stål, 1871, are being reported for the first time from India. Both are widespread species but have never been recorded from India.

A relatively less known assassin bug, Rhaphidosoma atkinsoni Bergroth, 1893 (Hemiptera: Heteroptera: Reduviidae: Harpactorinae) is recorded from Maharashtra State, India, for the first time. Redescription and illustrations of the species, along with the notes on morphology and natural history, are provided.

A new Emesinae species, Bagauda atypicus sp. nov., is described from Maharashtra, India. It is an atypical member of the genus Bagauda and the tribe Leistarchini because both male and female are micropterous and display a character not found in any Leistarchini described so far, namely presence of prominent, erect and blunt, humeral tubercles. The species is cavernicolous because the specimens were collected in old caves. Association with spider webs was observed.

We report Batocera lineolata Chevrolat, 1852, based on four records, from Manipur and Nagaland states in Northeast India. These records are the first time this species has been found in India. We also provide a brief redescription of B. lineolata.

The assassin bug, Epidaus wangi Chen, Zhu, Wang & Cai, 2016 was originally described from Tibet, China.  It is being reported from India for the first time.
