See text Trilacuna is a genus of goblin spiders native to Southeast Asia, first described by Tong & Li in 2007.

[2] 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.

[2] As of February 2019[update], it contains 29 species.
