Algeria

Colouration.
Creamy gray or yellowish brown, prosoma with distinct radial small dark bands especially along posterior eyes, opisthosoma with a longitudinal band in which outer lines are dark. Femora of legs without any band, but two clear dark patches on tibia ventrally (
Figs 50a–b
); ventral opisthosoma with a uniform dark marking with a notch at its anterior side (
Fig. 50c
).
Remarks.
Lucas (1846)
provided an illustration and a detailed description of colouration of this species, and noted that the ventral opisthosoma is decorated with two dark brown longitudinal bands, which meet in their posterior part, resembling the letter V. This character can be seen in specimens preserved for a long time in several species of the
dufouri
group. Even a compact marking in a freshly collected specimen can turn into V-shaped marking after preservation. In the illustration of
O. oraniensis
(
Lucas 1846
: pl. 11, fig. 9) no pattern is present on dorsal opisthosoma and no dark bands on the legs are illustrated, the body is uniformly coloured. This can be generally observed in specimens preserved for a long period.
Lucas (1846)
named the species after the type locality, the
Oran
region in the north-western part of
Algeria
. One
Eusparassus
specimen collected from
Oran
(deposited in ZSM) is designated here as
neotype
to avoid confusion with similar parapatric species of the group.
Known geographical distribution and habitat.
