Genus Leptoglossus Guérin-Méneville, 1831

Hypselonotus was redescribed by Hahn (1833a: 186-187, pl. 30), with included species Hypselonotus interruptus Hahn, 1833 (= Hypselonotus fulvus (De Geer, 1773) and Hypselonotus dimidiatus Hahn, 1833. Hahn’s publication of 1826 is accepted as valid in, for example, founding the genus Dicranocephalus Hahn, 1826; yet modern authors use the name Hypselonotus Hahn, 1833 for a well-known American genus that includes both species mentioned in the 1833 work but not that mentioned in 1826. Anisoscelis was described without included species by Berthold (1827), following Latreille (1825), a work that used only vernacular names for genera. Germar (1829: 296) used Anisoscelis as a subgenus of Coreus, giving as examples Cimex nugax Fabricius, 1781 (= Dicranocephalus agilis (Scopoli, 1763)), Cimex femoratus Fabricius, 1775 (= Acanthocephala femorata (Fabricius, 1775) or Rhinuchus femoratus (Fabricius, 1775)), Lygaeus calcar Fabricius, 1803 (= Physomerus grossipes (Fabricius, 1794)) and Cimex valgus Linnaeus, 1758 (= Elasmopoda valga (Linnaeus, 1758)). None of these is currently regarded as a species of Anisoscelis or even of Anisoscelini. Latreille (1829a: 196) may take priority over Germar (1829). Latreille included 15 species in Anisoscelis in his 1829 publication. Packauskas & Schaefer (2001: 253) regarded the action of Laporte (1833: 31) in selecting Lygaeus foliaceus Fabricius, 1803 as an example of the genus as a type species fixation. I can find no indication in Laporte’s work that this was his intention. Osuna (1984) elevated Allen’s (1969) divisions and species-groups of Leptoglossus to full generic status, founding the three new genera indicated above and recognising Theognis as a full genus with type species Theognis lineosus Stål, 1862, apparently unaware of Kiritshenko’s (1935) designation of Hypselonotus scriptus Hahn, 1826. If a generic or subgeneric name is required for Leptoglossus gonagra (Fabricius), Fabrictilis Osuna, 1984 is available.
