Abstract

Two new genera of Oodini LaFerté-Sénectére, 1851 are described: Bamaroodes gen. n. (type species: Hololeius cyaneus Facchini, 2011) for Bamaroodes cyaneus (Facchini, 2011), comb. n., here placed in tribe Oodini and removed from Chlaeniini Brullé, 1834; and Thaioodes gen. n. (type species: Thaioodes piceus sp. n.) for Thaioodes piceus sp. n. (type locality: Khon Kaen, Thailand). The new genera are closely related and belong to the same lineage as evidenced by the following combination of characters: body shape semi-elongate; discal setiferous pore lacking in interval 3 of elytra; mesocoxa without lateral seta; tarsomere 5 setose ventrally; joints of the claws of tarsomere 5 parallel, situated closely to each other. The two genera are readily distinguished from one another by a number of distinct characters. Further, the tribal position of two other genera is reconsidered. The monospecific Hololeius LaFerté-Sénectére, 1851 is redescribed and its current placement within Chlaeniini is confirmed, though it might be distantly related to the two new genera. Analysis of character states in species of Holosoma Semenov, 1889 leads me to transfer the genus from Oodini to Chlaeniini. Pictures of the taxa dealt with here are provided, including habitus, external characters, and genitalia. In addition, all the genera of the Oodini from the Oriental Region, including genera of Oriental Chlaeniini with oodine facies, are keyed for the first time.

Abstract All scientific names of Trachypachidae, Rhysodidae, and Carabidae (including cicindelines) recorded from America north of Mexico are catalogued. Available species-group names are listed in their original combinations with the author(s), year of publication, page citation, type locality, location of the name-bearing type, and etymology for many patronymic names. In addition, the reference in which a given species-group name is first synonymized is recorded for invalid taxa. Genus-group names are listed with the author(s), year of publication, page citation, type species with way of fixation, and etymology for most. The reference in which a given genus-group name is first synonymized is recorded for many invalid taxa. Family-group names are listed with the author(s), year of publication, page citation, and type genus. The geographical distribution of all species-group taxa is briefly summarized and their state and province records are indicated. One new genus-group taxon, Randallius new subgenus (type species: Chlaenius purpuricollis Randall, 1838), one new replacement name, Pterostichus amadeus new name for Pterostichus vexatus Bousquet, 1985, and three changes in precedence, Ellipsoptera rubicunda (Harris, 1911) for Ellipsoptera marutha (Dow, 1911), Badister micans LeConte, 1844 for Badister ocularis Casey, 1920, and Agonum deplanatum Ménétriés, 1843 for Agonum fallianum (Leng, 1919), are proposed. Five new genus-group synonymies and 65 new species-group synonymies, one new species-group status, and 12 new combinations (see Appendix 5) are established. The work also includes a discussion of the notable private North American carabid collections, a synopsis of all extant world geadephagan tribes and subfamilies, a brief faunistic assessment of the fauna, a list of valid species-group taxa, a list of North American fossil Geadephaga (Appendix 1), a list of North American Geadephaga larvae described or illustrated (Appendix 2), a list of Geadephaga species described from specimens mislabeled as from North America (Appendix 3), a list of unavailable Geadephaga names listed from North America (Appendix 4), a list of nomenclatural acts included in this catalogue (Appendix 5), a complete bibliography with indication of the dates of publication in addition to the year, and indices of personal names, supraspecific names, and species-group names.
