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
).
