A male of Enicoscolus is described for the first time. Enicoscolus brachycephalus is redescribed based on two males and one female of E. brachycephalus from Mexico, found in the collection of the American Museum of Natural History, New York. The general pattern of the male terminalia is similar to other Bibionini. Sternite 9 is largely fused to the...

Bibionidae, like other Bibionomorpha, are found primarily on decaying wood, humus-rich soil, and roots. In some cases, they can cause damage to cultivated plants. Some species emerge and fly in large groups. They can be collected using Malaise traps or by netting after emerging. Larvae can be serious agricultural pests, adults are important pollinators and sometimes the only ones, especially of orchids. The objective of this paper is to contribute to the knowledge of the Family Bibionidae. For this, a bibliographic survey of Bibionidae was carried out in the years 1949 to 2021. Only complete articles published in scientific journals and expanded abstracts presented in national and international scientific events were considered. Data were also obtained from platforms such as: Academia.edu, Frontiers, Qeios, Pubmed, Biological Abstract, Publons, Dialnet, World, Wide Science, Springer, RefSeek, Microsoft Academic, Science and ERIC.
