Item A black fly of the subgenus Simulium (Psaroniocompsa) (Simuliidae, Diptera) from the high Andes of Colombia. American Museum novitates ; no. 2513(New York, N.Y. : American Museum of Natural History, 1973) Wygodzinsky, Pedro W."Simulium (Psaroniocompsa) schmidtmummi, new species, is described from the Colombian Andes, where it has been found at high altitudes between 3050 and 3450 meters. All previously known species of the subgenus are found in lowland areas not exceeding 1000 meters altitude. The new species differs from all others in having only four filaments to the gill of the pupa; six is the usual number in Psaroniocompsa"--P. [1].Item Description of a black fly of the subgenus Simulium (Pternaspatha) from the high Andes of Ecuador (Diptera, Simuliidae). American Museum novitates ; no. 2670(New York, N.Y. : American Museum of Natural History, 1979) Wygodzinsky, Pedro W.; Coscarón, Sixto."Simulium cotopaxi, new species, collected between 3500 and 4400 meters in the Ecuadorian Andes is described. It shares many derived characters with members of the nemorale group of Simulium (Pternaspatha), but differs by the unique pattern of the scutum of the female and the posteriorly emarginated paraproct, as well as by the extraordinarily enlarged scapus and pedicellus of the antenna of the male. The new species was found more than 1000 km. norh of the previously known northern limit of the subgenus"--p.

(Robert Leslie), 1912-1968.; Wygodzinsky, Pedro W.Item Description of the first genus of physoderine assassin bugs (Reduviidae, Hemiptera) from the New World. American Museum novitates ; no. 2504(New York, N.Y. : American Museum of Natural History, 1972) Wygodzinsky, Pedro W.; Maldonado Capriles, Jenaro.; Fairchild, G. B."The reduviid subfamily Physoderinae was known to consist of the large genus Physoderes Westwood, ranging over the Oriental Region and Mauritius, and 11 additional small genera, restricted to Madagascar and the Comoro Islands. The present paper contains the description of the first New World physoderine bug, Cryptophysoderes fairchildi, new genus and species, based on a male and a female collected in a hollow tree in the Canal Zone of Panama. The authors cannot advance any opinion on the zoogeographical relationships of the new genus and its position within the physoderines, because a cladistic system of the subfamily does not yet exist"--P. [1].Item Description of three unusual species of the black fly subgenus Simulium (Ectemnaspis) from the Andes of Colombia (Diptera, Simuliidae). American Museum novitates ; no. 2736(New York, N.Y. : American Museum of Natural History, 1982) Wygodzinsky, Pedro W.; Coscarón, Sixto."Three new species of the genus Simulium - S. bicornutum, S. furcillatum, and S. simplex - collected near and above 3000 m. in the Andes of Colombia are described. These three species agree closely in their color pattern and overall structure with the species of the subgenus Simulium (Ectemnaspis) in which they are included. The three Colombian species differ from all other known members of the subgenus by the modified gills of their pupae. In the species of Simulium (Ectemnaspis) previously described, pupal gills consist of bundles of simple filiform elements. In one of the new species (S. bicornutum) the gills are halfmoon-shaped; in the second (S. furcillatum) the gills are still vaguely halfmoon-shaped, but the upper arm of each gill bears three filiform appendages. In the third species (S. simplex) the gills consist of five tubular structures arising at different levels from a common stalk"--P. [1].Item Descriptions and redescriptions of species of the blackfly genus Simulium from the northern Andes (Simuliidae, Diptera).

American Museum novitates ; no. 2411(New York, N.Y. : American Museum of Natural History, 1970) Wygodzinsky, Pedro W.; Stys, Pavel.Item A new species-group of the blackfly genus Simulium from western South America (Simuliidae, Diptera, Insecta). American Museum novitates ; no. 2433(New York, N.Y. : American Museum of Natural History, 1970) Wygodzinsky, Pedro W.; Coscarón, Sixto.Item Notes and descriptions of Machilidae from the Old World (Microcoryphia, Insecta). American Museum novitates ; no. 2555(New York, N.Y. : American Museum of Natural History, 1974) Wygodzinsky, Pedro W."A key to the species of Machilanus Silvestri and the description of the new species hebraeus, insensilis, lapidicola, schmidi, and swani are presented. The last four species are from the Himalayas, some collected from as high as 19,000 feet; the first is from Israel, a considerable extension westward of the range of the genus, known formerly only from Central Asia. The close relationship of Machilanus to the genus Stachilis Janetschek from the Balkans is shown. Characters of the first males reported for the genus Praetrigoniophthalmus Janetschek and for Silvestrichilis trispina (Wygodzinsky) are briefly described"--P. 3.Item Notes on South American black flies of the tribe Prosimuliini (Simuliinae, Simuliidae, Diptera). American Museum novitates ; no. 2529(New York, N.Y. : American Museum of Natural History, 1973) Wygodzinsky, Pedro W.; Coscarón, Sixto.; Peña G., Luis E."The present paper contains the result of the study of some prosimuliine black flies collected by the authors in Chile. The pupa of Cnesiamima atroparva Edwards is described and illustrated for the first time. The pupa of Cnesiamima was found to share derived (synapomorphic) characters with the pupa of Paraustrosimulium; this, together with the existence of synapomorphic structures in the genitalia of the male of the two genera, suggests that both have a common Recent ancestor not shared by any other known black fly genus. New locality data and observations on the morphology of other genera and species are also given"--P. [1].Item Results of the zoological explorations of Dr. E. [i.e. Z.] Kaszab in Mongolia. 202, Thysanura and Microcoryphia (Insecta). American Museum novitates ; no. 2401(New York, N.Y. : American Museum of Natural History, 1970) Wygodzinsky, Pedro W.; Kaszab, Zoltán.Item A review of Simulium (Pternaspatha) Enderlein (Simuliidae, Diptera). Bulletin of the AMNH ; v. 136, article 2(New York : [American Museum of Natural History], 1967) Wygodzinsky, Pedro W.; Coscarón, Sixto.Item A review of the Mesoamerican and South American black flies of the tribe Prosimuliini (Simuliinae, Simuliidae). Bulletin of the AMNH ; v. 151, article 2(New York : [American Museum of Natural History], 1973) Wygodzinsky, Pedro W.; Coscarón, Sixto."The black fly fauna of cool and cold temperate South America is composed of a comparatively small number of species of Simulium (Simuliinae, Simuliini) and several genera and species of the Prosimuliini. This survey of Neotropical Prosimuliini, which also includes Guatemalan and Mexican highland forms, is a taxonomic treatment mainly on the generic level accompanied by notes on biology and geographical distribution. The following genera, as arranged by their geographical areas, are dealt with: Mayacnephia, new genus (type: Simulium pachecolunai De Leon) and Tlalocomyia Wygodzinsky and Díaz Nájera (Mesoamerican highlands); Araucnephia, new genus (type: Simulium montanum Philippi) and Araucnephioides, new genus (type: Araucnephioides schlingeri, new species) (Mediterranean climate area of central Chile); Cnesia Enderlein, Cnesiamina, new genus (type: Simulium atroparvum Edwards) and Paraustrosimulium Wygodzinsky and Coscarón (Valdivian and Magellanic areas of southern Chile, and western Patagonia); and Lutzsimulium d'Andretta and d'Andretta (coastal ranges of southern Brazil). Species are also described, redescribed, or discussed as well as illustrated, except for the large genus Gigantodax which is planned to be monographed later. Cnesia ornata and Cnesia pusilla (western Patagonia) are new species; Cnesia gynandrum is synonymized with Cnesia dissimilis. None of the genera listed is found in America north of Mexico, or on other continents. It has not been possible to trace the origin and routes of dispersal of the Latin American prosimuliine genera, but some intergeneric affinities, especially among sympatric genera, are postulated"--P. 133.Item A review of the silverfish (Lepismatidae, Thysanura) of the United States and the Caribbean area. American Museum novitates ; no. 2481(New York, N.Y. : American Museum of Natural History, 1972) Wygodzinsky, Pedro W."An analysis of the composition of the lepismatid fauna of the United States and the Caribbean area is made, with special emphasis on the geographic origin of the species. Among the 13 species found in the United States, only three are autochthonous; among the 13 species reported from the Caribbean area, six seem to be endemic. All other species probably have been introduced by man. Keys for the determination of the lepismatids of the United States and of the Caribbean area are followed by an enumeration of all species concerned, with distributional data and taxonomic comments. Four species are reported for the first time from the United states, viz., Acrotelsa collaris, Ctenolepisma diversisquamis, C. targionii, and Stylifera gigantea. Lepisma mucronata Packard is synonymized with Acrotelsa collaris (F.), and Ctenolepisma reducta Folsom with C. diversisquamis Silvestri; Ctenolepisma campbelli Barnhart is transferred to Thermobia. The female of Ctenolepisma hummelincki Wygodzinsky is described for the first time. Peliolepisma calva, until now only known from Ceylon, is reported from Guyana and Cuba, where it is supposedly a common house lepismatid"--P. [1].Item Revision of the black fly genus Gigantodax (Diptera, Simuliidae). Bulletin of the AMNH ; no. 189([New York] : American Museum of Natural History, 1989) Wygodzinsky, Pedro W.; Coscarón, Sixto."A taxonomic study of the genus Gigantodax Enderlein is presented, including keys, descriptions, redescriptions, discussions, illustrations, and distributional and biological information. Gigantodax is the largest genus of Neotropical Prosimuliini, with 64 species extending along the Andean system from Mexico to Tierra del Fuego. Because most species described herein were collected by the authors from breeding sites, the morphology of immature and adult stages is presented.

Bulletin of the AMNH ; no. 200([New York] : American Museum of Natural History, 1991) Wygodzinsky, Pedro W.; Schmidt, Kathleen."The taxonomy of the New World Encicocephalidae is treated in detail at the generic and specific level with the exception of Systelloderes Blanchard, for which only the genus is diagnosed. The tribe Systelloderini is resurrected to contain the genus Systelloderes within the Encicocephalinae. The new genera Chiricocoris, Lysenicocephalus, Neoncylocotis, Urnacephala, and Xenicocephalus are described. Thirty-eight new species are described in 9 genera. Enicocephalus marimutti Kritsky and E. yvonneae Kritsky are treated as junior synonyms of E. cubanus Barber; E. emarginatus Champion is treated as a junior synonym of E. pilosus Champion; Oncylocotis braziliensis Kritsky is treated as a junior synonym of Neoncylocotis stannardi (Kritsky). Several new combinations are created, particularly for species transferred to the genus Neoncylocotis. Keys are provided for all genera except Xenicocephalus, and for all species except those of Systelloderes. General reviews are provided for the following subject areas: biology; somatic structures and diagnostic characters; and genitalia, homologies, and the phylogeny of the New World taxa. Scanning electron microscopy is used intensively for the study of morphological structure, and the results in the form of micrographs are presented in conjunction with numerous line drawings"--P. 5.Item Revision of the Triatominae (Hemiptera, Reduviidae), and their significance as vectors of Chagas' disease. Bulletin of the AMNH ; v. 163, article 3(New York : American Museum of Natural History, 1979) Lent, Herman.; Wygodzinsky, Pedro W."The reduviid subfamily Triatominae contains numerous species which are actual or potential vectors of Chagas' disease, caused by Trypanosoma cruzi. All Triatominae require bloodmeals for their complete development. Most species feed on small terrestrial or arboreal mammals, especially didelphids, edentates, and rodents; others are associated with bats, and some are found with birds. Several triatomines have colonized human habitations, where they transmit Chagas' disease to man and his domestic animals. The epidemiologically most important species are the wide-ranging Triatoma infestans, T. dimidiata, and Rhodnius prolixus. The following are also active vectors of Chagas' disease, although more localized: Triatoma barberi, brasiliensis, carrioni, guasayana, maculata, patagonica, pallidipennis, phyllosoma, pseudomaculata, rubrofasciata, sordida, and rubida, Panstrongylus chinai, megistus, and rufotuberculatus, Rhodnius ecuadoriensis, and pallescens. A survey of the external structures of the Triatominae and their terminology is presented to facilitate use of the keys and comprehension of the descriptions. The Triatominae share a derived character not found in other reduviids, viz., a membranous connection between the second and third rostral segments. This structure permits an extensive flexure of the third segment, in connection with the act of bloodsucking. The trichobothria of the second antennal segment of the adult are described for the first time; their number and arrangement are diagnostic on the tribal and in some cases generic level. Trichobothria were also discovered on the anterior femora of Cavernicola pilosa. Another previously unknown structure is the presence of a pair of flasklike invaginations on the terminal rostral segment of Dipetalogaster maximus. The shape of the stridulatory sulcus of the prosternum is shown to be, in some cases, diagnostic on the generic level. Some Triatominae have adopted strategies that allow them to expand their abdomen for the ingestion of unusually large bloodmeals; three such strategies, involving membranization of part of the connexivum and correlated modifications of the lateral part of the abdomen, are described. The male genitalia of plesiomorphic triatomines are of simple structure, but derived forms are shown to have variously specialized phalli, involving modifications of the articulatory apparatus, the basal plate struts, and the dorsal phallosoma plate. First and fifth instar nymphs are studied morphologically, mainly on the generic level. A newly discovered character of first instar nymphs is the absence or presence of a group of elongate sensory hairs on the metatarsus. Nymphs of all instars of Microtriatoma and Parabelminus have three pairs of spongy fossulae as do the adults, a condition unique in the subfamily. The subfamily Triatominae is restricted to the Nearctic, Neotropical, and Oriental regions, entering the Australian region marginally. Triatoma rubrofasciata is tropicopolitan. There are 13 genera in the Western Hemisphere, with the center of diversity in South America. The Oriental region contains one endemic genus and an apparently monophyletic species group of Triatoma, a genus occupying the entire range of the subfamily. The division of the Triatominae into five tribes is maintained. One tribe, the Triatomini, is paraphyletic; the Rhodniini, Cavernicolini, Bolboderini, and Alberproseniini are either monophyletic or monotypic. The five tribes, 14 genera, and 111 species are described or redescribed and illustrated and their synonyms given; host relations and epidemiological role are stated where known. Keys for tribal, generic, and specific identification of adults as well as for generic identification of first and fifth instar nymphs are given in English, and, where pertinent, in Spanish and/or Portuguese. Six new species are described: Triatoma guazu (Paraguay); Linshcosteus chota and kali (India), Belminus herreri (Panama), Parabelminus yurupucu (Brazil: Bahia), and Microtriatoma borbai (Brazil: Parana). Nine names are newly synonymized: Triatoma ninoi Carcavallo et al. with T. eratyrusiformis Del Ponte; T. pessoai Sherlock and Serafim and T. bahiensis Sherlock and Serafim, both with T. lenti Sherlock and Serafim; T. novaeguineae Miller with T. leopoldi (Schouteden); T. pallidula Miller with T. migrans Breddin; T. phyllosoma usingeri Mazzotti with T. pallidipennis (Stal); T. bruchi Mazza and Jörg with T. rubrovaria (Blanchard); T. garciabesi Carcavallo et al. with T. sordida (Steal); Rhodnius amazonicus Almeida et al. with R. pictipes Stal"--P. 127.
