Diagnosis.
Muma (1970)
distinguishes
E. spinipalpis
from the related
E. striatus
by the lack of markings on the legs and palpi and the “curved lateral margins of the median caudal opercular notch.”

Discussion.
Since
Kraepelin (1899a)
described the female only, the placement of this species is speculative as the presence of the male VDC is a critical criterion in determining this genus. The female genital operculum figured by
Muma (1970)
closely resembles that of
Eremocosta striata
. Its
type
locality on the southern Baja Peninsula would seem to separate it from
E. striata
but until further specimens are examined, the placement will remain in
Eremocosta
.
Kraepelin (1899a)
described the palp as having spines “with width equal to height,” hence the name.
Eremocosta formidabilis
female also has some short, robust palpal setae that might be interpreted as spines. Muma’s (1987)
Eremocosta
key does not include
E. spinipalpis
but his unpublished manuscript (in library of JOB) does.
