Diagnosis.
The male of
Thymoites ilhabela
new species
differs from those of the other species in the shape of the carapace, with distal area forming a neck and anterior eyes in the tip of the projection (
Figs. 11, 12
,
49–53
), the palp resembles that of
T. mirus
Levi, 1964
(see
Levi, 1964
: fig. 34), but differs in the conductor non-pointed and the shape of embolus (
Fig. 10
,
56–59
). The female of
T. ilhabela
new species
is close to
T. mirus
Levi
(see
Levi, 1964
: figs. 32, 33), but differs from it in the smaller spermathecae (
Figs. 13, 14
) and the shape of fertilization ducts (
Fig. 14
).
