Etymology.
The species name refers to branched (Latin:
ramosus
) pouch lobes (Latin:
sacculus
) of the T7 gland.
Diagnosis.
In the male sex very similar to
Dz.
(
Dz.
)
altotuberculata
, distinguished by the shorter, broadly rounded latero-posterior corners of T7, the huge opening of the T7 glandular pit and the ramose pouch lobes.

Description.
Size.
Length of pronotum in male 2.30–2.43 mm (mean 2.37 mm), in female 2.24–2.43 mm (mean 2.37 mm); N 4/7.
Male structures.

Dz.
(

)
planotuberculata
and
Dz.
(
Dz.
)
altotuberculata
, more similar to the latter one. Median concavity of
T6
similarly deep as in latter one, but much wider (
Figs. 20I–K
). Latero-posterior corners of
T7
similarly produced as in the first mentioned species, but much broader; pre-glandular margin (
pm)
as long as in
Dz
. (
Dz.
)
altotuberculata
; opening of
glandular pit
larger, occupying more than two thirds of the length of the tergite, elevations (
el
) of the posterior wall of the pit and of the bulge (
bu
) behind the pit similarly strongly sculptured as in
Dz.
(
Dz.
)
altotuberculata
.
Pouch tubes
with many short side branches, diameter of the main axis subbasally wider than elsewhere; interior cuticular lining with long, bristle-like microtrichial processes as in the preceding two species, inclined towards the exit (
Figs. 25J, K
).
T10
with median part of posterior border shallowly but distinctly concave (
Fig. 20H
).
Spatular bristles
laterally on T5–7: densely arranged only on T7 (
Figs. 20E–G
), thinning out towards the latero-posterior corners. No
glandular pores
on T2.
Colouration.
Tegmina.
In both sexes transparent, without dark markers.
Male.
Similar to
Dz
. (
Dz
.)
planotuberculata
.
Head dark, with yellowish post-interocular stripe; forelegs for most part dark, mid- and hindlegs with extended yellowish parts; discs of thoracic nota dark, margins transparent; T2–6 anteriorly of the ridge dark, posteriorly on a relatively light ground colour with a dark maculose pattern producing at three positions more extended dark areas, T6 sometimes completely dark (
Figs. 20A–C, I–K
), T7 between bulge and the broadly dark lateral margin yellowish (
Figs. 20D
, 21, 22); sternites mainly dark, lateral margins broadly yellowish.
Female.
Head dark, with yellowish post-interocular stripe; legs almost completely yellowish; discs of thoracic nota dark, sometimes with moderately extended lightenings, margins transparent (
Figs. 20M, N
); tergites anteriorly of ridge dark, posteriorly on a yellowish ground colour with a moderately extended dark maculose pattern; sternites mainly dark, with broadly yellowish lateral margins.
Distribution.
Only known from two neighbouring localities in the massive Jebel Bou Iblane at the northern end of the Middle Atlas: One (Ma 184) between the distribution areas of
Dz.
(
Dz.
)
planotuberculata
and
Dz.
(
Dz.
)
altotuberculata
, at the other locality (Ma 13) they were found together with the first mentioned species, at elevations of
1300–1700 m
(
Figs. 27
,

).
