Dipoena santaritadopassaquatrensis
new species
: (14–16) Male: (14) palp, ventral, (15) body, dorsal, (16) body, lateral. (17–18) Epigynum: (17) ventral, (18) dorsal, cleared (FS, first spermathecae; SS, second spermathecae; T, tegulum). Scale bars: 0.25 mm.
Etymology.
The specific name is a noun in apposition, taken from the
type
locality.
Diagnosis.
The male of
Dipoena santaritadopassaquatrensis
new species
resembles that of
D. plaumanni
Levi, 1963
(see Levi, 1963: 155, figs. 99–100, 104) in the projection in tegulum (
Fig. 14
), but differs in the trajectory of the sperm duct in the tegulum, closer to the projection in tegulum (
Fig. 14
) and in the pattern and shape of the carapace in lateral view, higher (
Fig. 16
). The female of
Dipoena santaritadopassaquatrensis
is close to
D. plaumanni
(see Levi, 1963: 155, figs. 101, 102) in the presence of two pairs of rounded spermathecae, first spermathecae developed (
Figs. 17, 18
), but it differs from the latter species by having the less second spermathecae developed and the copulatory openings more distant from the first spermathecae (
Fig. 18
).
