Etymology.
The species name refers to the curved (Latin:
curvus
) bristles (Latin:
seta
) of the T7 gland of males.

Description.
Size.
Length of pronotum in
holotype
2.11 mm, relative length of pouch lobes of T7 gland 45– 59% (mean 53.1%) (N7,
Table 2
).
Male structures.
T7
with
pouch
lobes still shorter than in the preceding species, shortly obtuse-conical (
Figs. 5D–F
,
6D
); bristles loosely distributed over the full width of the pit opening, long pit bristles strongly curved, short bristles distally irregularly curled (
Fig. 6E–H
); lateral
pit
similar and similarly variable as in the preceding species.
Glandular pores
laterally on T2: present, but in low numbers along the anterior border of the tergite (
Fig. 2H
).
Distribution.
Spain
,
Andalusia
, western spurs of the Cordillera Penibetica: at two localities between Algeciras and Cadiz, elevation
100 m
(
Figs. 27
,
28
).
Remarks.
The specimens from the two localities (Sp 214, 219) show clear differences in the length of the pouch lobes; even their ranges are distinctly separate; on the other hand, specimens from locality 219 show some overlap with the corresponding range of
Dz
. (

.)
brevisacculata
.
Nevertheless, the similarities in the arrangement and shape of the pouch bristles between the specimens of the two localities and the differences in these features from the specimens of the preceding species justifies considering them as a separate species. This assumption is strongly supported by the colouration of T6; in
Dz
. (
Dz
.)
brevisacculata
it is almost uniformly dark, while in
Dz
. (
Dz
.)
curvisetosa
there is a large central lightening. The conformity in colouration between the specimens from the two localities (Sp 214, 219) also pleads for their belonging to the same species in spite of the differences in the length of the pouch lobes.
