Weberiella De Carlo, 1966 (Insecta: Heteroptera: Belostomatidae) revisited
The small species of Belostoma (Heteroptera: Belostomatidae): revision of plebejum group.
The Belostoma plebejum group includes seven small species with the ventral diverticulum of male genitalia recurved ventrad and two new species are described and illustrated, and new synonymies are proposed.
Revision of the Belostoma dentatum group sensu Nieser (Insecta, Heteroptera, Belostomatidae).
The authors' findings suggest that the dorsal arms of the phallotheca curved apically to be diagnostic of this complex, and Belostoma bordoni is herein included in the dentatum group based on male genitalic morphology, and the subspecies B. subspinosum subpinosum (Palisot de Beauvois) and B.SubSpinosum cupreomicans (Stål) are synonymized as a single valid species.
On the taxonomic status of the genus Horvathinia Montandon (Hemiptera: Belostomatidae)
It is considered that the southern South American genus Horvathinia is monotypic, except for H. lenti, which could not be examined and is synonymized with H. pelocoroides Montandon.
The small species of Belostoma Latreille (Heteroptera, Belostomatidae). III
The aspect of the prosternal keel, the ratio between the width of the ventral diverticulum of phallus and its length in ventral view, and the aspect of dorsal arms of ventral Diverticulum have proven useful for better species delimitation.
