Trilacuna

Trilacuna is a genus of goblin spiders native to Southeast Asia, first described by Tong & Li in 2007. They look similar to members of Silhouettella, but males can be distinguished by their large palpal femur, among several other more complicated defining features. The name is a combination of the Latin terms "tri" and "lacuna", referring to the three-branched endites in males and the three-notched labium in females.
