Elephantotus, a new genus of Tabanidae from the Amazon coast, Brazil, is described based on a new species E. tracuateuensis. Five females were collected in Pará State, and a male in Maranhão State. Arguments are presented for separating the new genus from Dasybasis, as well as the possibility of its occurrence being related to the nesting sites of coastal birds. The new species is characterized by its large size (x = 2.15 cm, n = 5 females), glabrous eyes, reddish-brown tegument, light brown frontal callus not touching the edges of the eyes, extending up to the vertex that has traces of ocelli, basal plate of the antennal flagellum with obtuse angle, without a tooth or spine, wings hyaline, with brown basal cells, without appendix in the fork of vein R4+5, and genital furca wide with extended flaps.
象虻属，巴西亚马逊海岸虻科的一个新属，基于新物种E. tracuateuensis进行描述。在帕拉州采集到五只雌性，在马拉尼昂州采集到一只雄性。文中阐述了将该新属与达斯虻属区分开来的依据，以及其出现可能与沿海鸟类筑巢地点有关的可能性。新物种的特征为体型大（雌性平均体长x = 2.15厘米，n = 5）、眼无毛、体表红棕色、浅棕色额瘤不接触眼边缘、延伸至有单眼痕迹的头顶、触角鞭节基部板呈钝角、无齿或刺、翅透明、基部细胞棕色、R4+5脉分叉处无附器，生殖叉宽且有扩展的瓣。
