Central American Species

AbstractThe North and Central American species formerly placed in the genus Mycetoporus are revised. Two genera are recognized, Mycetoporus Mannerheim and Ischnosoma Stephens, each with 18 species. The morphological and historical basis for this division is discussed. Ten species of Mycetoporus are described as new: bipunctatu, floridensis, impunctatus, neomexicanus, nidicola, pacificus, rufohumeralis, segregatus, smetanai, and triangulatus. Ten species of Ischnosoma are described as new: arizonense, ashei, costale, durangoense, fimbriatum, hermani, lecontei, mexicanum, pecki, and suteri. Mycetoporus boreelus J. Sahlberg, a species restricted to the Palearctic region, is removed from synonymy with M. nigrans Mäklin and Mycetoporus insignis Mäklin is found to be a junior synonym of M. americanus Erichson. Mycetoporus discalis, M. punctatissimus, and M. punctulatus, all species described by Hatch (1957), are transferred to the genus Bryoporus subgenus Bryophacis and the name Tachinus humidus Say is treated as a nomen dubium in the genus Mycetoporus.The usage of the generic names Mycetoporus Mannerheim and Ischnosoma Stephens is discussed. The North American species of the genus Mycetoporus are placed in six species groups and those of the genus Ischnosoma are placed in four species groups.A neotype is designated for Mycetoporus nigrans Mäklin and lectotypes are designated for M. americanus Erichson, M. insignis Mäklin, M. tenuis Horn, M. lucidulus LeConte, M. consors LeConte, Ischnosoma pictum (Horn) and I. flavicolle (LeConte). The following species were transferred from Mycetoporus to Ischnosoma and are new combinations: pictum Horn, splendidum Gravenhorst, flavicolle LeConte, virginiense Bernhauer, coxale Sharp, hospitale Fall, californicum Bernhauer and Schubert, and curtipenne Bernhauer.All genera, species groups, and species are described and the species are illustrated with line drawings and scanning electron photomicrographs. Keys are provided to distinguish the genera Mycetoporus and Ischnosoma and for all the species in each genus. The New World distribution of each species is mapped. The biology of each species, if known, is discussed.

AbstractThe species of the genus Tachinus (Staphylinidae: Tachyporinae) of North and Central America are revised. Forty-four species are recognized, of which eight are described as new; eight species names are placed in synonymy. The subgenera Drymoporus Thomson and Porodrymus Rey are placed in synonymy with Tachinus and the genus is divided into 17 species groups based on an examination of both the Nearctic and the Palearctic fauna. The distribution of each species is mapped and the male genitalia, the male and female eighth abdominal sternites and tergites, and the male seventh sternite are illustrated for every species. A neotype is designated for T. fumipennis Say, and lectotypes are designated for all the North and Central American species of Tachinus described by Gravenhorst, Erichson, Mäklin, Horn, and Sharp. Diagnostic keys for males and females are included. A brief discussion of the nomenclatural history of the genus, of collecting techniques, and of the major diagnostic characters is included.

AbstractThe genus Megasoma Kirby as it occurs in North and Central America is discussed, and the taxonomic history of this group in this area is reviewed. A key is presented to aid in the separation of the 10 forms currently known from these areas, as well as one species that may be taken in the future. Each species is illustrated and discussed. Three new species, Megasoma sleeperi from Southern California, Megasoma cedrosa from Central Baja California, and Megasoma lecontei from Southern Baja California, are described.

AbstractTwo new species, Tachinus beckeri from northwestern British Columbia and southern Yukon Territory and T. californicus from southern California, are described and their major diagnostic characters illustrated with line drawings and scanning electron photomicrographs. Tachinus jacuticus campbelli is placed in synonymy with T. jacuticus jacuticus and a new subspecies, T. jacuticus ullrichi, from Quebec and Labrador is named. Tachinus thruppi Hatch is removed from synonymy with T. frigidus and considered a valid species. Both T. thruppi and T. frigidus are redescribed and illustrated. A new, revised key to the species of Tachinus is included.New distributional data are presented for 40 species and new or revised distributional maps are presented for 24 species. Changes in classification of Tachinus proposed by Ullrich in his revision of the world species are reviewed and those that are accepted are incorporated into a revised classification of the North American species. These changes are included in a check list of the North and Central American species of the genus.

The species of Diplonevra Lioy of Central America are reviewed, with particular attention to the structure at the base of the posterior face of the hind femur. Six species are recognized, five of which are new to science: D. ereba, D. goliatha, D. hypermeka, D. truncatiseta, and D. gnoma. The sole described species, D. setigera (Malloch), is found to be a senior synonym of the North American D. gaudialis (Cockerell) and the Brazilian D. impressa (Borgmeier), both new synonyms.
