Distribucion geografica de Lutzomyia verrucarum (Townsend, 1913) (Diptera, Psychodidae, Phlebotominae), vector de la batonellosis humana en el Peru

Lutzomyia verrucarum (Townsend, 1913) (Diptera: Psychodidae), vector natural de la verruga peruana o enfermedad de Carrión es una especie propia del Perú. Su distribución geográfica esta entre los paralelos 5º y 13º25' de latitud Sur, se encuentra en los valles Occidentales e Interandinos de los Andes. La distribución altitudinal de Lu. verrucarum en los diversos valles es variable; asi: Occidentales, desde 1100 hasta 2980 msnm e Interandinos, de 1200 a 3200 msnm. En ciertas áreas verrucógenas no hay correlación entre la presencia de Lu. verrucarum y la enfermedad de Carrión lo que suguiere la existencia de vectores secundarios.

Primeira contribuição ao conhecimento da tribu Juriniini Townsend: gênero Euempheremya Townsend, 1927: (Diptera, Tachinidae)

The author described two new species belonging to the genus Euempheremyia Towsend, 1927: E. albuquerquei sp. n. and E. elyowaldi sp. n., from Brazil. The redescription of E. paulensis Towsend, 1927 is based on a paratype male, from the Departamento de Zoologia, São Paulo. The genus Euhuascaraya Towsend, 1927 is placed in synonymy with Euempheremyia Towsend, 1927.

Contribuição ao conhecimento da tribu Ormiini. II: gênero ormiophasia townsend, 1919 (Diptera, Tachinidae)

The present paper is a contribution to the knowledge of the genus Ormiophasia Townsend, 1919, based mainly on the male genital characters. Five new species are described from Brazil.

Contribuição ao conhecimento da tribu Ormiini. III: gênero Euphasiopteryx Townsend, 1915 (Diptera, Tachinidae)

This is a contribution to the knowledge of the Tribu Ormiini in wich the author presents redescriptions of euphasiopteryx depleta (Wiedemann, 1830), Euphasiopteryx ochracea (Bigot, 1888) and describes a new species: Euphasiopteryx rosenoi sp. n. from Brazil.

Contribuição ao conhecimento da tribu Ormiini: IV: gêneros Ormia Robineau Desvoidy, 1830, e, Euphasiopteryx Townsend, 1915 (Diptera, Tachinidae)

Studying thirteen speciemens of the genus Ormia Robineau-Desvoidy, 1830, and one of Euphasiopteryx Towsend, 1915, the author describes six new species: Ormia mendesi sp. n., Ormia lenkoi sp. n., Ormia carreirai sp. n., Ormia crespoi sp. n., Ormia wygodzinskyi sp. n., and Euphasiopteryx lenti sp. n. from Brasil and Argentina. The importance of the ocelli as a generic character, as stated by Towsend (1936) is discussed based on the absence of ocelli in Ormia mendesi sp. n. and Ormia crespoi sp. n. and its presence in Euphasiopteryx lenti sp. n. A key for the determination of Ormia species is presented based chiefly on the males external morphological characters.

Uma nova espécie de Punaphyto Townsend, 1916 (Diptera, Sarcophagidae)

Male and female of Punaphyto lopesi, a new species from Equador are described and illustrated.

Uma nova espécie de Arachnidomyia Townsend, 1934 (Diptera, Sarcophagidae)

A new species of the genus Arachnidomyia Townsend, 1934 is described and illustrated, based on male specimen from Chile.

Two new Neotropical species of the genus Oxysarcodexia Townsend (Diptera, Sarcophagidae)

Two new Neotropical species of the genus Oxysarcodexia Townsend (Diptera, Sarcophagidae). Oxysarcodexia nitida sp. nov. and O. notata sp. nov. from Peru are described and illustrated based on male specimens. These new taxa are morphologically more similar to O. vittata (Walker) and O. xon (Dodge) respectively.

Ectoparasites of bats (Chiroptera, Furipteridae), with a description of a new species of Synthesiostrebla Townsend (Diptera, Streblidae) from Brazil

Ectoparasites of bats (Chiroptera, Furipteridae), with a description of a new species of Synthesiostrebla Townsend (Diptera, Streblidae) from Brazil. Records of ectoparasites from furipterid bats are restricted to bat flies (Streblidae). Only three streblid species were known before this work: Trichobius pallidus (Curran, 1934), Strebla wiedemanni Kolenati, 1856, and Synthesiostrebla amorphochili Townsend, 1913. A second species of Synthesiostrebla is described here, increasing the geographical distribution of the genus to east of the Andes. Synthesiostrebla cisandina sp. nov. was found on Furipterus horrens (Cuvier, 1828) in southeastern Brazil. Anterior parts of the body, wing, tergite 7, epiproct and male genitalia are illustrated, and a key to females for species of Synthesiostrebla is provided.

Description of the male of Lepidodexia (Xylocamptopsis) teffeensis (Townsend) (Diptera, Sarcophagidae)

Description of the male of Lepidodexia (Xylocamptopsis) teffeensis (Townsend) (Diptera, Sarcophagidae). The male of Lepidodexia (Xylocamptopsis) teffeensis (Townsend, 1927) is described and illustrated for the first time based on material housed in the entomological collection of Museu Nacional, Rio de Janeiro (MNRJ). This monotypic subgenus has been recorded in the Brazilian Amazon Rainforest, first in the state of Amazonas and now in the state of Pará. The general structure of the male terminalia is similar that of other Lepidodexia, especially of the subgenus Lepidodexia, by the short distiphallus, juxta with apical projection, and vesica with a membranous spinous lobe.

Comparative morphology of the spermathecae of some species of Chrysomya Robineau-Desvoidy and Cochliomyia Townsend (Diptera, Calliphoridae)

Comparative morphology of the spermathecae of some species of Chrysomya Robineau-Desvoidy and Cochliomyia Townsend (Diptera, Calliphoridae). Little is known about the morphology of the chitinized structures of the spermathecae of the Calliphoridae. In this work, the spermathecae of Chrysomya albiceps Wiedemann, 1819, C. megacephala Fabricius, 1794, Cochliomyia macellaria Fabricius, 1775 and C. hominivorax Coquerel, 1858 are described and illustrated. The occurrence in one species of four spermathecae, an atypical form for blow flies, was recorded for the first time. The analysis of these structures will allow a better understanding of this group as well as provide taxonomic characters for future phylogenetic studies.

BAT-BORNE RABIES IN LATIN AMERICA

The situation of rabies in America is complex: rabies in dogs has decreased dramatically, but bats are increasingly recognized as natural reservoirs of other rabies variants. Here, bat species known to be rabies-positive with different antigenic variants, are summarized in relation to bat conservation status across Latin America. Rabies virus is widespread in Latin American bat species, 22.5%75 of bat species have been confirmed as rabies-positive. Most bat species found rabies positive are classified by the International Union for Conservation of Nature as “Least Concern”. According to diet type, insectivorous bats had the most species known as rabies reservoirs, while in proportion hematophagous bats were the most important. Research at coarse spatial scales must strive to understand rabies ecology; basic information on distribution and population dynamics of many Latin American and Caribbean bat species is needed; and detailed information on effects of landscape change in driving bat-borne rabies outbreaks remains unassessed. Finally, integrated approaches including public health, ecology, and conservation biology are needed to understand and prevent emergent diseases in bats.

La fauna flebotomica (Diptera: Psychodedae) de tres províncias de la region nor oriental del Marañon, Peru

En localidades ubicadas entre los distritos de San José de Lourdes (05°03'Longitud Sur), provinda de San Ignacio y Lonya Grande (06°05'30" Longitud Sur), provinda de Utcubamba, Region Nor Orietital del Maranón, donde la bartonellosis humana o Verruga Peruana es endémica, se capturaron 2774 flebótomos entre 1987 y 1992; identificándo se 13 especies; 11 correspondeu al género Lutzomyia, 1 a Brumptomyia y 1 a Warileya. De las especies capturadas, Zutzomyia sp. similar a Lutzomyia serrana y Lutzomyia maranonensis sp. n., Galati, Cáceres & Le Pont, son las mas abundantes (89.74%), por lo que, se especula que puedeit ser consideradas vectores potenciales de la Verruga Peruana. Se reporta Lutzomyia verrucarum (Townsend, 1913) por primem vez para la provinda de Utcubamba.
