Type species. Gaoligonga changya Miller, Griswold & Yin , sp. n.

Etymology. Named for the Gaoligong mountain range. The gender is feminine.

Diagnosis. Male distinguished by characteristics of the palp: cymbium almost completely envelopes the palpal bulp, cymbial base in prolateral view nearly touches opposite cymbial margin ( Figs 40A , 46A ); retrolateral face of cymbium with a basal keel, a median keel, and a distal lobe separated from the median keel by an invagination ( Figs 40B , 46B ); embolus spiral, tip variable. Male further distinguished from most other mysmenids by the presence of two strong setae near the base of each chelicera, but this is much more conspicuous in G. changya ( Fig. 38A ) than G. zhusun ( Fig. 46D ) and some other mysmenids described from the region also have strong cheliceral setae (e.g., Mysmena rostella Lin & Li, 2008 , M. arcilongus Lin & Li, 2008 , M. taiwanica Ono, 2006 ).

Female distinguished by the absence of femoral spots or a posterior abdominal tubercle in combination with a raised, ridged, central knob of the epigynum (Figs 41A, 43E, 47D).

Description. Femoral spots absent. Abdomen without posterior tubercle. Male with head moderately to strongly raised ( Figs 40E , 46E ), sulci absent, tibia I without prolateral macrosetae.

Male palp with a cymbium that almost completely envelopes the palpal bulp, cymbial base in prolateral view nearly touches opposite cymbial margin ( Figs 40A , 46A ); retrolateral cymbial face with a basal keel, a median keel, and a distal lobe separated from the median keel by an invagination ( Figs 40B , 46B ). Embolus spiral, tip variable.

Vulva: Epigynum a weakly ( Fig. 43D ) or strongly ( Fig. 43A ) sclerotized plate, without scape, with a raised, ridged, central knob (Figs 41A, 43E, 47D).

Species. Gaoligonga changya , sp. n., G. zhusun , sp. n.
