Visual Description
Acanthocera marginalis is a horse fly species characterized by distinct coloration patterns on its wings and body. Observations from the TreeOfLife-200M dataset indicate that the species possesses a dark brown thorax and abdomen, with notable banding patterns.[1] The wings are hyaline with a dark brown anterior margin that covers the costal and subcostal cells, as well as parts of the radial and anterior cubital cells.[2]
Morphology
The male of Acanthocera marginalis has been described with contiguous, glabrous eyes, featuring larger ommatidia on the upper two-thirds and smaller ones on the lower third. The subcallus exhibits whitish pruinosity, while the gena, parafacial, and clypeus are characterized by a glossy black integument, with the clypeus also showing areas of grayish pruinosity. The antennae have an orange scape, a pedicel with black setulae, and a postpedicel that is orangish at the base and black distally, with a straight, non-curved dorsal tooth.
The thorax features two subtle median longitudinal bands of yellow pruinosity and yellow setulae. The legs have dark brown femora, while the fore and hind tibiae are brownish on the basal half and whitish on the distal half; the mid tibia is white with white setulae, and the tarsus is orange-brown.
Distribution
Acanthocera marginalis is widely distributed across South America, including Bolivia, Brazil (Acre, Amapá, Amazonas, Mato Grosso, Pará, Roraima, Tocantins), Colombia, Ecuador, French Guiana, Guyana, Peru, Surinam, and Trinidad.
