Etymology. Patronymic in honor of Nobel Peace Prize laureate Aung San Suu Kyi.

Diagnosis. Monotypic genus; see diagnosis for genus.

Description. Carapace tan, male clypeus with pair of macrosetae ( Fig. 52B ; absent in female, Fig. 52A ); AME separated by more than one diameter in male, less than one diameter in female. Sternum brown. Legs tan. Femoral spot on leg I. Abdomen tan ( Fig. 48 ).

Male palp: Cymbium simple, envelopes only ventral face of palpal bulb; tip of cymbium a single piece, without grooves or lobes ( Fig. 49 A-B). Embolus coil makes ca.10 turns (Fig. 51B). Expanded palp reveals long basal haematodocha permitting bulb to extend far from cymbium ( Fig. 50C ).

Vulva: Epigynum unsclerotized with only a short fleshy projection ( Fig. 50A , 52C ). Spermathecae small and round, set far anterior from epigastric furrow ( Fig. 50B ). Copulatory ducts make many turns around fertilization ducts (fig. 49C).

Male (CASENT 9024332): Total length 0.63, carapace 0.33 long, 0.29 wide, clypeus 0.12, sternum 0.20 long, 0.21 wide, coxa IV separated by 2.00 times their width. Leg I: patella d1, tibia d1, metatarsus p1; Leg II: patella d1, tibia d1; Leg III: patella d1, tibia d1; Leg IV: patella d1, tibia d1. Metatarsal macrosetae gently curved distally (Fig. 51C). Metatarsal trichobothria:TmI: 0.34; TmII: 0.31; TmIII: 0.36. Leg measurements: see Appendix A. Epiandrous gland spigots in two widely spaced clusters of two spigots each (Fig. 51D).

Female (CASENT 9024332): Total length 0.90, carapace 0.37 long, 0.36 wide, clypeus 0.07, sternum 0.24 long, 0.24 wide, coxa IV separated by 2.00 times their width. Leg I: patella d1, tibia d1; Leg II: patella d1, tibia d1; Leg III: patella d1, tibia d1; Leg IV: patella d1, tibia d1. Metatarsal trichobothria: TmI: 0.34; TmII: 0.31; TmIII: 0.38. Leg measurements: see Appendix A. Spinnerets ( Fig. 52 D-F).
