(type species: Abdosetae hainan Fu, Zhang & MacDermott, 2010 , by original designation).

Diagnosis. This genus can be distinguished from all other phrurolithid genera by the male abdomen ventrally with a double longitudinal row of long setae behind the epigastric fold ( Fig. 1B ); the chelicerae have a single long spine anteriorly; the male palpal femoral protuberance is not well developed, only slightly swollen; the female epigyne lacks glandular appendages.

Description. Small spiders. Carapace low, smooth, highest near fovea, widest at coxae II and III. Chelicerae with three well separated promarginal and two close retromarginal teeth, with single long spine anteriorly. All femora without dorsal spine; femur I usually with three prolateral spines distally, femur II usually with two prolateral spines; tibia I usually with six proventral spines and seven retroventral spines, tibia II usually with six pairs of ventral spines; metatarsus I usually with four pairs of ventral spines, metatarsus II usually with four proventral spines and three retroventral spines. Abdomen oval, with narrow anterior dorsal scutum in dorsal view and double longitudinal row of long setae behind the epigastral fold in ventral view in males; without dorsal scutum and long setae in female. Male palp: femur only with somewhat swollen, with distal concavity; tibia with one large retrolateral tibial apophysis (prolateral margin often modified), one slender dorsal tibial apophysis and one conspicuous ventral tibial hump; tegulum convex, usually with conspicuous apophysis; sperm duct short, thick and distinct; embolus relatively long, situated at tip of tegulum. Female epigyne: epigynal plate with pair of shallow concavities or flat, copulatory openings concealed in anterior margins of concavities or exposed; copulatory ducts short, connected to two transparent bursae; spermathecae small and usually spherical.
