Diagnosis.
Females of
S. boyaca
sp. n.
resemble those of
S. gaita
,
S. parang
and
S selenopoides
by the presence of an anterior, transversal furrow on the epigyne (
Figs 83
,
112, 114, 116
). They are distinguished from
S. gaita
by the presence of an anterior atrium bearing the CO (absent in the latter species) and from
S. parang
and
S. selenopoides
by the lateral lobes completely separated by the MS (
Fig. 83
) (touching each other posteriorly in
S. parang
and medially in
S. selenopoides
).
