Trilacuna Tong & Li, 2007  

Type species: Trilacuna rastrum Tong & Li, 2007   , by original designation

Diagnosis: Trilacuna   can be distinguished from all other oonopid genera by the enlarged male palpal femur, the very complicated embolus-conductor complex, the branched endites in males and the notched labium.

Description: Large and completely chitinized oonopid spiders. Carapace dorsally smooth, with rows of short hairs; carapace sides granulated. Eyes six, anterior lateral eyes separated from each other by at least their diameter; posterior median eyes almost touching and slightly separated from posterior lateral eyes, posterior eye row straight. Chelicerae with small cone-shaped tubercle on upper inner margin. Endites of male mesodistally branched; labium with deep notch at middle in both sexes; sternum with distinct radial furrows. Tibiae and metatarsi of leg I and II with spines. Opercula ovoid, not modified. Male palpal femur enlarged, other segments normal; cymbium outstretched, not fused with bulb. Bulb large, somewhat pear-shaped; embolus-conductor complex complicated. Female epigastric area without external copulatory structures.
