TAXONOMIC DISCUSSION
Leptoneta View in CoL is a genus described from Western Europe ( France). It is mainly distributed in Mediterranean region, East Asia, and a few in North America. However, all species from outside the Mediterranean region are probably misplaced ( Platnick 1986, 2007). The Chinese Leptoneta species should probably be included in one or more new genera in a future revisional work. In this paper, all the Chinese Leptoneta species except L. arquata Song & Kim, 1991 View in CoL , which is only known from female, are arranged into the following four species groups mainly based on the characters of male palp.
1. L.maculosa View in CoL group, including nine species: L. maculosa View in CoL , L. anocellata View in CoL , L. changlini View in CoL , L. cornea View in CoL n. sp., L. exilocula View in CoL n. sp., L. foliiformis View in CoL n. sp., L. tunxiensis View in CoL n. sp., L. setulifera View in CoL n. sp. and L. wangae View in CoL n. sp. This group is characterized by the presence of strong spines at least on distal ventral half of male palpal femur, the distally situated apophysis on palpal tibia (missing in L. foliiformis View in CoL n. sp., L. maculosa View in CoL and L. tunxiensis View in CoL n. sp.), and the absence of ventral spines on palpal tibia.
2. L. huanglongensis group, including seven species: L. huanglongensis , L. huisunica , L. lingqiensis , L. monodactyla , L. nigrabdomina , L. taiwanensis and L. taizhensis . This group is characterized by the absence of ventral strong spines on male palpal femur, the presence of apophyses on distal palpal tibia, and the absence of strong spines on ventral palpal tibia.
3. L. microdonta group, including six species: L. microdonta , L. hangzhouensis , L.tianxinensis , L. trispinosa , L. unispinosa and L. xui . This group is characterized by the presence of strong spines on ventral male palpal tibia.
4. L. miaoshiensis group, including two species: L. miaoshiensis and L. falcata . This group is characterized by the absence of any strong spines or apophysis on male palpal femur and tibia.
