The systematics of the representatives of the genus Rhabdochona, parasitic in fishes of North and Central America, is revised. Rhabdochona cascadilla Wigdor 1918, R. kidderi Pearse 1936, R. decaturensis Gustafson 1949, R. cotti Gustafson 1949, R. ovifilamenta Weller 1938, R. milled Choquette 1951, and R. canadensis sp.nov. are considered as the valid species of this region. The first six species are redescribed and illustrated. The new species, R. canadensis, is described from the cyprinids Hybopsis gracilis (flathead chub; type host), H. plumbea (lake chub), and Rhinichthys cataractae (longnose dace) of Alberta; the latter form is characterized largely by the presence of one or two long filaments at each pole of the eggs, by 14 teeth in the prostom, by the presence of the cuticular spike at the tip of the tail, and by the character of the spicules. The species R. pellucida Gustafson 1949 is regarded as a synonym of R. cascadilla Gustafson 1949, and R. laurentiana Lyster 1940 as a synonym of R. ovifilamenta Weller 1938. Rhabdochona serrata (Wright 1879) Ko and Anderson 1969 is transferred to the genus Cystidicola as species inquirenda. The hosts and geographical distribution of the current members of the genus are reviewed. The paper is supplemented by a key for the identification of the species parasitic in fishes of North and Central America.

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.

Three new species belonging to the tribe Nymphistrini of the obligate myrmeco- and termitophilous subfamily Haeteriinae (Coleoptera: Histeridae) are described from Central America: Nymphister rettenmeyeri sp. n. (Costa Rica and Panama), Trichoreninus carltoni sp. n. (Belize and Honduras) and T. neo sp. n. (Costa Rica and Panama).  Identification keys for the Central American species of both genera are prepared.  Available host records for N. rettenmeyeri confirm the symbiosis of the genus with Eciton army ants: the species has been found in colonies of E. burchelli (Westwood), E. hamatum (Fabricius) and E. mexicanum Roger.  Host records are not available for the new species of Trichoreninus as all known specimens were collected by flight intercept traps.

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.

This paper revises the Mexican and Central American species of Heteromeles M. Roemer and Photinia Lindley (Rosaceae, subfamily Maloideae). One genus, Heteromeles, is monotypic, whereas in Photinia five species are recognised. Of the Photinia species, one, P. mexicana, is highly distinct and the remainder are closely related to, or part of, the P. microcarpa complex. A numerical taxonomic study has been conducted to assist in differentiating the last-named group of taxa. One new species, Photinia guerreris, and two new subspecies of Photinia microcarpa, sspp. elliptica and hintonii, are described. In Photinia microcarpa ssp. hintonii a new variety, var. brevis, is created. Key words: Heteromeles, Photinia, Rosaceae, taxonomy, Mexico, Central America.

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.

The taxonomy and natural history of the ant genus Adelomyrmex Emery is reviewed for the Central American region. Theyare small, litter-inhabiting ants most often collected in Berlese and Winkler samples. Although the genus and its relativeshave a pantropical distribution, Central American cloud forests are the only places where they are abundant and diverse.Several Adelomyrmex species are mountain-top endemics with very restricted ranges, and climate change clearly posesthe threat of mountain-top extinction. The 21 Mexican and Central American species are treated in some detail and a keyto the 26 mainland New World species is provided. Nine new species are described, eight from Mexico and Central Amer-ica (A. anxiocalor sp. nov., A. bispeculum sp. nov., A. dentivagans sp. nov., A. marginodus sp. nov., A. metzabok sp. nov.,A. nortenyo sp. nov., A. paratristani sp. nov., and A. quetzal sp. nov.) and one from the oceanic Isla del Coco in the easternPacific (A. coco sp. nov.). New synonymy is proposed for Adelomyrmex tristani (Menozzi, 1931) (= A. brevispinosus Fernández, 2003, syn. nov.).
