Dieta chlorion Simon, 1906: 286 (description of female) Type material. Holotype female from INDIA: Tamil Nadu: Nilgiris, Simon leg., 1906, deposited in (MNHN), examined.

Diagnosis. The female epigyne of O. chlorion is most similar to that of Oxytate forcipata Zhang & Yin, 1998 , from which it can be easily distinguished by the relatively narrower anterior hood (broader in O. forcipata ), and postero-medially placed and inwardly oriented copulatory openings (medio-laterally placed and anteriorly oriented in O. forcipata ) (cf. Figs 1C , 5A with fig. 1 in Zhang & Yin, 1998, and fig. 280B in Song et al. 1999).

Redescription. Female (holotype, Figs 1A–D ). Measurements: Body length 6.82. Carapace length 2.83, width 2.41. Abdomen length 3.86, width 1.97. Eye diameters: ALE 0.08. AME 0.06. PLE 0.07. PME 0.06. Eye interdistances: AME–AME 0.18, ALE–AME 0.12, PME–PME 0.19, PLE–PME 0.29, ALE–PLE 0.25, AME–PME 0.24, ALE–ALE 0.51, PLE–PLE 0.85, AME–PLE 0.45, ALE–PME 0.21.

Leg formula: 1234. Colour in alcohol: overall pale yellow to colourless, markings faintly visible ( Figs 1A–B ).
