Diagnosis
.
Similar to
O. baenai
n. sp.
in the general shape of the gonopods but characterized by a slenderer promerite with a more protruding lateral apical process, a slenderer mesomerite devoid of subapical processes, and details in the distal part of the solenomerite showing additionally a subapical tooth (
St
), an acuminate curved process (
ac
) and an anterior saw-like process (not with a pointed tip as in
O. baenai
n. sp.
).
Etymology
.
The species epithet refers to the
type
locality of the species, the province of Jaén.
Description
.
L:
25 mm
, H: 2.1 mm, 53 PR+1 AR+T. Females: L 28.5–37.5 mm, H: 2.7–4.1 mm, 50–53 PR+2 AR+T. General colour yellowish, perhaps faded after a long stay in alcohol, dorsum greyish with a thin black longitudinal line, lateral sides below the line of the ozopores yellowish. Head: dark brown on the occipital part, yellowish toward the labral zone. Labral margin and mouthparts bright yellow. Eyes composed of ca. 34 black ocelli in 9 vertical rows. Prozonites pallid greyish; metazonites yellow showing a regular striation; ozopores rounded, opening behind the suture; the latter rectilinear, sometime curving at ozopore level.
Telson: Preanal ring yellowish with a caudal projection bearing 2+2 setae and a hyaline tip; subanal scale setose; anal valves yellowish with 5–6 setae on the surface, a marginal row of several short setae and a submarginal row of longer ones.
Gonopods: Promerite (
Fig. 61
) subrectangular (comparable to
O. baenai
) but narrower and more elongate, apically protruding in a lateral slender digit-shaped process (
Dg
); mesal ridge (
Mr
) broad, apically folded and protruding but not extending beyond the apical margin. Rudimentary telopodite (
T
) conspicuous, triangular, located distally. Posterior gonopod (
Figs 62–64
): Mesomerite (
Ms
) a simple rod, uniformly broad and slightly longer than promerite (
Figs 62, 63
), straight, bearing no apical projections; solenomerite (
S
) broad at base, constricted at midlength and strongly expanded distally as broad lamella bent laterad (
Fig. 62
); basal surface of solenomerite thickened and serrated anteriorly, bearing several spines protruding in an anteromesal jagged lamella (
jl
) to midlength of the process (
Fig. 62
); distal part complex, ramified into: 1) a conical process (
Cn
) bearing several striae on the surface, 2) a mesal folded process (
Tg
) lodging the opening of the seminal groove and with two pointed tips pointing apicad, 3) a strong submarginal tooth (
St
), 4) an acuminate curved, serrated process (
ac
) pointing laterad, and 5) a posterior, saw-like process (
Swp
) bearing asymmetrical strong teeth. Seminal groove (
g
) running posteriorly from the fovea (
F
) located at the base up to process
Tg
(
Figs 62, 64
). Paracoxite (
Px
) stout, of the same length as the solenomerite, with irregular anterior margin, uniformly broad and apically strongly bent (
Figs 62, 63
).
