Xiaoliguang Lin & Li , gen. nov.

Type species: Xiaoliguang huarong Lin & Li , sp. nov. from Vietnam .

Etymology. The genus name is after Xiaoliguang , nickname for one of the 108 outlaws in the classical Chinese literature Outlaws of the Marsh; masculine in gender.

Diagnosis. The new genus is similar to Edelithus by the small size and small PME with indistinct black pigment around the eye cup. However, the new genus can be distinguished from Edelithus by the male scutum covering the entire abdomen (vs. nearly half in Edelithus ), the male palp lacking a dorsal tibial apophysis (vs. present in Edelithus ) and having a tegular apophysis (vs. absent in Edelithus ). Females of the new species can be distinguished from all other Phrurolithidae genera by the lack of bursa.

Chelicerae with three promarginal and four retromarginal teeth. Endites and labium yellow-brown. Sternum yellow. Legs brown with black setae. Opisthosoma oval, dark brown, covered with black setae. In the male, dorsal scutum covers almost entire opisthosoma. Spinnerets yellow-brown.

Male palp lacking patellar apophysis; retrolateral tibial apophysis present. Tegular apophysis almost as long as embolus, tegular apophysis and embolus slightly curved. Conductor white, terminus pointed.

Female epigynal plate oval, copulatory openings obvious, copulatory ducts inconspicuous. Spermathecae oval; fertilization ducts almost as long as spermatheca.
