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.

Central American Species

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 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.

Central American Species

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.).

Central American Species

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.

The genus Agrilus participates in a number of mimicry complexes. At least 23 species in México and Central America areconsidered to belong to one of the complexes that putatively have flies as models. In this complex, characterized by thecolor pattern of red-blue/black-pale, 11 new species are described —Agrilus updikei, new species; Agrilus marthae, newspecies; Agrilus dipterioides, new species; Agrilus opitzi, new species; Agrilus exquisitus, new species; Agrilus zumba-doi, new species; Agrilus coloradoensis, new species; Agrilus frankparkeri, new species; Agrilus cavei, new species;Agrilus alajuelensis, new species; and Agrilus percaroides, new species. Two species groups are recognized, based onAgrilus basalis Chevrolat and A. percarus Kerremans. Previously described species are provided with a diagnosis or redescribed, and additional specimen records are given. All species are illustrated.

Three New Species

The Cretaceous and early Cenozoic species of the shallow-marine, warm-water bivalve Plicatula from California (United States) and Baja California (Mexico) are reviewed, and three new species are named. All of these species are representatives of Plicatula and not of the closely related taxon Harpax, which is associated with high-latitude and cool-water regions. The earliestknown Cretaceous species of Plicatula from the study area is P. variata Gabb, 1864, from Lower Cretaceous (Hauterivian Stage) strata in northern California, and our studies show it to be conspecific with Plicatula onoensis Anderson, 1958.Plicatula allisoni new species is from Lower Cretaceous (Albian Stage) strata in Baja California, Mexico. Plicatula modjeskaensis new species is from Upper Cretaceous (Turonian Stage) strata in the Santa Ana Mountains, southern California. A possible new species from the same strata is also mentioned. A poorly preserved specimen of Plicatula? sp. is known from Upper Cretaceous (upper Campanian to lower Maastrichtian) strata in northern California.The only Paleocene species of Plicatula from the study area is P. ostreiformis Stanton, 1896, from lower Paleocene strata of Lake County, northern California, and our studies show it to be conspecific with Ostrea buwaldana Dickerson, 1914. The only previously described Eocene species of Plicatula from the study area is P. juncalensis Squires, 1987, from lower middle Eocene (“Capay Stage”) strata of Los Angeles County, southern California. Plicatula surensis new species is from middle lower Eocene (“Capay Stage”) strata in Baja California Sur, Mexico. In addition, there is a Plicatula? sp. from Eocene strata of Baja California Sur, Mexico.Although Plicatula is of uncommon occurrence north of Baja California, its thermophilic trait makes it useful in recognizing periods of warm climate.

A revision of the Central American species of the genus Brachiacantha was undertaken to update the knowledge of the Central American species of the genus. Material of several collections was reviewed, using original descriptions and keys, and comparing with the type material. Twenty-five species of the genus Brachiacantha were found in Central American material, including nine new species: B. nubes Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. dentata Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. isthmena Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. aurantiapleura Nestor-Arriola, Solís and Toledo-Hernández, sp. nov., B. invertita Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. papiliona Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. tica Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. hexaspina González, Větrovec and Nestor-Arriola, sp. nov., and B. mimica Nestor-Arriola and Toledo-Hernández, sp. nov. Nomenclatural changes include Brachiacantha gorhami (Weise), comb. nov., B. guatemalensis (Gorham), comb. nov., and Brachiacantha duodecimguttata Leng, syn. nov. for B. lepida Mulsant. The male genitalia of the species B. fenestrata Gorhan, B. octostigma Mulsant, B. aperta Weise, and B. cachensis Gorhan are described and illustrated for the first time. New records include B. indubitabilis Crotch and B. bipartita Mulsant (Costa Rica and Guatemala), B. gorhami (Weise) (El Salvador), and B. cachensis Gorham (Panamá). A key to the species is included.

Four new venerid species from the Cretaceous of the North American Pacific Slope are described and four previously described species are reassigned. Of the new species, two are allotted to new genera: Rhaiphiale based upon Rhaiphiale pharota n. sp. and Egrona based upon Egrona fallax n. sp., both Turonian in age and from southern California. The other new species are Loxo quintense n. sp., of late Maastrichtian age from California, and Paraesa cedrina n. sp., late Albian in age from Baja California, Mexico. The previously described species “Meretrix” arata Gabb, 1864, Turonian, and “?Meretrix” fragilis Gabb, 1869, late Maastrichtian, are placed in the new genus Callistalox; “Meretrix” lens (Gabb, 1864), Campanian age, and Flaventia zeta Popenoe, 1937, Turonian, are provisionally assigned to Paraesa Casey, 1952. This is the first identification of Paraesa from the Pacific Slope of North America. No species of Flaventia Jukes-Brown, 1908, is now known in Pacific Slope faunas.

Different Origins

Species of the ectomycorrhizal genus Lactifluus, and often entire sections, are typically unique to a single continent. Given these biogeographic patterns, an interesting region to study their diversity is Central America and the Caribbean, since the region is closely connected to and often considered a part of the North American continent, but biogeographically belong to the Neotropical realm, and comprises several regions with different geologic histories. Based on a multi-gene phylogeny and morphological study, this study shows that Central America, Mexico and the Caribbean harbour at least 35 Lactifluus species, of which 33 were never reported outside of this region. It was found that species from the Caribbean generally show affinities to South American taxa, while species from the Central American mainland generally show affinities to Northern hemispheric taxa. We hypothesise that host specificity and/or climate play a crucial role in these different origins of diversity. Because of these different affinities, Caribbean islands harbour a completely different Lactifluus diversity than the Central American mainland. The majority of species occurring on the islands can be considered endemic to certain islands or island groups. In this paper, detailed morphological descriptions are given, with a focus on the unique diversity of the islands, and identification keys to all hitherto described Lactifluus species occurring in Central America and the Caribbean are provided. One new section, Lactifluus sect. Nebulosi, and three new species, Lactifluus guadeloupensis, Lactifluus lepus and Lactifluus marmoratus are described.
