The monogeneric family Brachypsectridae is redescribed based on adults and larvae, and distribution, biology, and ideas on the phylogenetic relationships are summarized. Presently available data from both adults and larvae support previous conclusions that the family is a basal member of the Elateroidea. The four described species of Brachypsectra LeConte are reviewed. Brachypsectra moronei Branham sp. n. is described from the Dominican amber; larvae of Brachypsectra fulva LeConte, Brachypsectra lampyroides Blair, and an unnamed species from Australia are described; and keys are given to males of all described species and to known larvae. In addition, a lectotype and paratypes are designated for the six recognized syntypes of Brachypsectra lampyroides Blair, 1930.
