Diagnosis.
Females most resemble
B. panamanus
but are distinguished from the latter and all other species by the following combination of characters: internal genitalia with short spermathecae without lobes (see Rudolph 1996: fig. 5), and leg I with black pattern (
Fig. 10D
).

Only known from

.
Natural History.
Specimens were collected in mountain pine forests. Females build
20 to 25cm
long tubeshaped burrows without covers, covering the entire interior with silks (Rudolph 1996).
Note.
Bolostromus holguinensis
was described by Rudolph (1996) the female
holotype
was deposited in
Cuba
,
one paratype
was deposited in
Berlin
(ZMB), and
one paratype
in
Dessau
(MNVD),
Germany
.
The
specimen in
Dessau
is currently misplaced and could not be found, the specimen from
Berlin
was the only one available, the redescription of the species is based on the
paratype
specimen from
Berlin
which is unfortunately juvenile.
