Etymology. The epithet ‘acuminatus’ refers to the sharp spine on dorso-lateral pronotum. The name is treated as an adjective.
Diagnosis. Baeus acuminatus sp. n. is different from all other Oriental species of Baeus because of the presence of following combination of character states: head, mesonotum and metasoma smooth except for the antero-lateral coriaceous reticulate patch on mesoscutum, dorso-lateral pronotum extending as a prominent spine and presence of long setae on mesoscutum and metasoma.
