A Revision Of The Genus Kaszabister Mazur (Histeridae, Histerinae, Exosternini), Michael S. Caterino, Nicolas Degalllier, Slawomir Mazur, Alexey K. Tishechkin
Michael S Caterino
We revise the four species of Kaszabister Mazur, 1972, one of which, Kaszabister barrigai sp. n., is described as new. The other species in the genus are K. rubellus (Erichson, 1834), K. ferrugineus (Kirsch, 1873) and K. carinatus (Lewis, 1888). The species are principally known from the subtropics of South America, with one in Central America. Lectotypes are designated for K. rubellus and K. ferrugineus, and a key is provided for all the species. Ants of the genus Solenopsis Westwood, mainly S. invicta Buren and S. saevissima (Smith), are documented as hosts of three of the four species.
A Systematic Revision Of Operclipygus Marseul (Coleoptera, Histeridae, Exosternini), Michael S. Caterino, Alexey K. Tishechkin
A Systematic Revision Of Operclipygus Marseul (Coleoptera, Histeridae, Exosternini), Michael S. Caterino, Alexey K. Tishechkin
Michael S Caterino
We revise the large Neotropical genus Operclipygus Marseul, in the histerid tribe Exosternini (Histeridae: Histerinae). We synonymize 3 species, move 14 species from other genera, sink the genus Tribalister Horn into Operclipygus, and describe 138 species as new, bringing the total to 177 species of Operclipygus. Keys are provided for the identification of all species, and the majority of the species are illustrated by habitus and male genitalia illustrations. The species are diverse throughout tropical South and Central America, with only a few species extending into the temperate parts of North America. The majority of species can be recognized by …
New Genera And Species Of Neotropical Exosternini (Coleoptera, Histeridae), Michael S. Caterino, Alexey K. Tishechkin
New Genera And Species Of Neotropical Exosternini (Coleoptera, Histeridae), Michael S. Caterino, Alexey K. Tishechkin
Michael S Caterino
We describe the following 8 new genera and 23 new species of Neotropical Exosternini. Conocassis gen. n. (Conocassis minor sp. n. [type species], Conocassis dromedaria sp. n., Conocassis trisulcata sp. n., and Conocassis invaginata sp. n.), Enkyosoma gen. n. (Enkyosoma rockwelli sp. n.), Pluricosta gen. n. (Pluricosta onthophiloides sp. n.), Pyxister gen. n. (Pyxister devorator sp. n. [type species] and Pyxister labralis sp. n.), Chapischema gen. n. (Chapischema doppelganger sp. n.), Scaptorus gen. n. (Scaptorus pyramus sp. n.), Lacrimorpha gen. n. (Lacrimorpha glabra sp. n. [type species], Lacrimorpha balbina sp. n., Lacrimorpha subdepressa sp. n., and Lacrimorpha acuminata sp. n.), …
A Revision Of The Genus Mecistostethus Marseul (Histeridae, Histerinae, Exosternini), Michael S. Caterino, Alexey K. Tishechkin, Nicolas Degallier
A Revision Of The Genus Mecistostethus Marseul (Histeridae, Histerinae, Exosternini), Michael S. Caterino, Alexey K. Tishechkin, Nicolas Degallier
Michael S Caterino
We revise the genus Mecistostethus Marseul, sinking the monotypic genus Tarsilister Bruch as a junior synonym. Mecistostethus contains six valid species: M. pilifer Marseul, M. loretoensis (Bruch), comb. n., M. seagorum sp. n., M. carltoni sp. n., M. marseuli sp. n., and M. flechtmanni sp. n. The few existing records show the genus to be widespread in tropical and subtropical South America, from northern Argentina to western Amazonian Ecuador and French Guiana. Only a single host record associates one species with the antPachycondyla striata Smith (Formicidae: Ponerinae), but it is possible that related ants host all the species.
