Nicagus
Nicagus is a monogeneric genus of stag beetles (family Lucanidae) comprising three described species: N. japonicus (Japan), N. obscurus (eastern and central North America), and N. occultus (western Texas). The genus represents the tribe Nicagini within subfamily Aesalinae. The discovery of N. occultus in unvegetated sand dunes marked an unexpected range extension and unusual habitat for the family.
