Genus Nesonotus

The genus Nesonotus was erected by Beier (1960) to include species from Lesser Antilles previously considered as belonging to Bliastes Stål, 1873 . Two groups of species might be recognized within Nesonotus : species of the Tricornis Group ( N. tricornis , N. reticulatus , N. caeruloglobus Hugel , n. sp.) with head slightly narrower than pronotum, face with distinct but not marked carinae with a distinct spine on the scape, and with long prosternal spines; and species of the Denticulatus Group (all the other species including N. vulneratus Hugel , n. sp.) having wide head with very marked carinae, without distinct spine on the scape but a blunt knob, with prosternal spines of medium size. Although Beier (1960) included the sharp spine on the scape in the diagnosis of Nesonotus , this character state does not occur in all species yet included in this genus.
