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.
Central America, diversity, horse flies, tabanids, taxonomy
Tabanidae is a family of Diptera that includes flies considered of medical and veterinary importance due to the blood sucking habits of the adults. Currently the group contains around 4,400 species worldwide (
The best known tabanid faunas in Central America are those of Costa Rica and Panama thanks in big part to the works of
Honduran species diversity is poorly known for many groups.
This work presents for the first time an overview of the tabanids of Honduras. By nature, this is vastly incomplete as there are many more habitats to sample and collections to revise. In comparison, Costa Rica with less than half the size of Honduras has more than twice the number of known species of tabanids. The aims of this article are: 1) to present the new findings regarding the species diversity in the country, 2) to integrate the records on the tabanid fauna of Honduras scattered in the literature, 3) to provide an updated list of the species, and 4) to create a key for the genera of tabanids known in the country.
Material of Tabanidae deposited at the Insect Collection at Zamorano University (
Distributional records were obtained from label data and from the literature.
A species distribution map was made for the new records using SimpleMappr (https://www.simplemappr.net/) and Microsoft Power Point v. 2112.
Photographs were taken using a Canon 100 mm lens mounted on a Canon Rebel T5i attached to a macro rail. Composite images were obtained using PICOLAY v. 2020–02–06 (http://www.picolay.de). Individual images were organized in plates in GIMP v. 2.10.24 (http://www.gimp.org).
Eighteen genera and 47 species were found in the 386 specimens examined. Thirteen species and two genera are recorded for the first time (Fig.
With these new records Honduras has now a diversity of 85 species of horseflies (Table
