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.[2] 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.[2] 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.[2]
The thorax features two subtle median longitudinal bands of yellow pruinosity and yellow setulae.[2] 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.[2]
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.[2]
