RESUMO

A catalog of the Tabanidae from Chile is provided. All valid names and synonyms for the 116 species and 25 genera known for the country including information about name, author, year of publication, page number, type species, type locality and references are listed. The species Dasybasis albohirta (Walker) is cited for the first time for Chile. The type locality of Dasybasis nigrifrons (Philippi) is corrected to Chile (Todos Los Santos Lake). The dates of the description of Tabanus nigrifrons Philippi (now Dasybasis), and Pangonia australis Philippi (now Pseudoscione) are corrected from their original description by Philippi; the original description dates for Tabanus andicola (now Dasybasis), and Tabanus magellanicus (now synonym junior of Dasybasis trita (Walker)) are corrected from 1865 to 1862. Three species previously recorded from Chile are deemed to have been misidentified or misrecorded from Chile: Esenbeckia (E.) cisandeana Wilkerson Fairchild and Esenbeckia (E.) enderleini Krber, and Esenbeckia (E.) testaceiventris (Macquart, 1848). The genus Dasybasis Macquart is the richest genus in Chile, with 33 species. Seven genera (Mycteromyia Philippi, Promycteromyia Coscarn Philip, Archeomyotes Philip Coscarn, Austromyans Philip Coscarn, Chaetopalpus Philippi, Pseudomelpia Enderlein, and Sixtomyia Krolow, Henriques Gonzlez), three subgenera (Esenbeckia (Astomyia) Burger, E. (Palassomyia) Fairchild, and Protodasyapha (Protodasyapha) Enderlein), and 64 species are known only from Chile. There are also one subgenus (Protodasyapha (Curumyia) Coscarn), and 36 specie with distribution shared only between Chile and Argentina.

RESUMO

This works presents information on the diversity of the Tabanidae of Honduras as a product of the examination of 386 specimens and a literature review. Thirteen species and two genera (Bolbodimyia and Dasychela) are recorded from the country for the first time. Eighty-five species distributed in 22 genera, five tribes, and three subfamilies are now known from Honduras. A key to the subfamilies, tribes, and genera of the known Honduran species is also included. All new records are mapped and illustrated to aid in the identification of the species.

RESUMO

BACKGROUND: The genus Dichelacera is widely distributed in the Neotropical region. The nominal subgenus is the most diverse with 67 species and one subspecies. NEW INFORMATION: We described Dichelacera lamasi n. sp., the 68th species of nominal subgenus, based on a female from Mato Grosso do Sul state, Brazil. Diagnosis, discussion and illustrations are also provided.

RESUMO

The Leucotabanus species with records in the Amazon are reviewed. Seven species are included: L. albovarius, L. exaestuans, L. flavinotum, L. janinae, L. pauculus, L. weyrauchi, and L. fairchildi n. sp., which is described herein. The male of L. weyrauchi is described for the first time. Another two non-Amazonian species, L. canithorax and L. sebastianus, were compared, illustrated, and discussed, with new distribution records for the latter species. A key for the seven Leucotabanus species found in the Amazon, along with diagnoses, discussions, distributions and illustrations, are presented.

RESUMO

The group of species related to Tabanus trivittatus include horse flies with striped abdomens and partially bare, inflated, subcallus. Herein we describe five new species and raise the number of valid species from 15 to 20, four of which occur in Brazil: T. albocapilus sp. n., T. dorsorufus sp. n., T. mackerrasi sp. n., T. macrocerus sp. n. and one that occur in Brazil, Bolivia and Peru: T. noncallosus sp. n. We also modified the keys from Fairchild (1976) for both sexes and briefly discuss the female genitalia.

RESUMO

Tabanid females are better known as hematophagous on man and other mammals, and linked to mechanical transmission of parasites. The association between tabanids and reptiles is poorly known, but has been gaining more corroboration through experiments and occasional observation in the tropics. The present study was conducted at a military base (CIGS/BI-2), situated 54 km from Manaus, Amazonas, in a small stream in a clearing (02 degrees 45'33"S; 59 degrees 51'03"W). Observations were made monthly, from April 1997 to March 1998, during two consecutive days. At the same time, other vertebrate animals were offered, including humans. However in this paper only data obtained on a common caiman, Caiman crocodilus (Linn.), and an anaconda, Eunectes murinus (Linn.), in diurnal observations from 05:30 a.m. to 18:30 p.m., will be discussed. A total of 254 tabanid specimens were collected, 40 from the anaconda and 214 from the caiman. Four tabanid species were recorded on these two reptiles: Stenotabanus cretatus Fairchild, S. bequaerti Rafael et al., Phaeotabanus nigriflavus (Kröber) and Tabanus occidentalis Linn. Diurnal activities showed species-specific patterns. The first three species occurred only in the dry season. T. occidentalis occurred during the whole observation period, and with increased frequency at the end of the dry season. We observed preferences for body area and related behavior of the host. Observations on the attack of tabanids on one dead caiman are also presented.
