Cryptachaea schneirlai
:
Yoshida, 2008: 39
(transferred to
Cryptachaea
).
Diagnosis.
The female is similar to that of
Cryptachaea dea
(
Buckup & Marques, 2006
)
(see
Buckup & Marques, 2006: 64
, figs. 5, 6) by the larger and oval spermathecae, and by presence and the shape of atrium (
Fig. 7
), but differ by the spermathecae close to each other, and by the shape of fertilization ducts forming a handle (
Fig. 8
).
Description.
Male described by
Levi (1959: 67)
. Here we provide the first illustration of the male body in dorsal view (
