Chobanov.
The nightly calling song consists of echemes with a variable number (3–19) of syllables (
Fig. 2
; syllable period 411±23 ms; SRR 2.4 Hz). In these syllables, a short opening hemisyllable (47±2 ms) is followed by a longer closing hemisyllable (163±8 ms) containing 50±2 impulses (
Fig. 3
), both having approximately the same amplitude.
The frequency spectrum of the male calling song has a very broad maximum around 20 kHz (
Fig. 5
).
The male tegmina are in shape similar to
U. elegans
, but the mirror in the right tegmen is oval, not roundish (
Fig. 6B
). The male stridulatory file carries about 90 teeth (
Fig. 7
;
Tab. 2
). In the middle of the file the inter-tooth intervals are about
65 µm
. The female stridulatory file (
Fig. 9D
) is in structure similar to that of the other
Uromenus
species
and in tooth density intermediate between the species of the
rugosicollis
group and
U. agarenus
.
Morphology.
This species has been grouped together with
U. melillae
Nadig, 1994
,
U. tobboganensis
Nadig, 1994
, and
U. alhoceimae
Nadig, 1994
, into the
Finoti
Subgroup. The taxa within this group are distinguished based on the shape of the genital appendages. Females of the
Finoti
Subgroup differ from the
Robustus
Subgroup by the distal protuberances of the lower ovipositor valve being hump-shaped or comb-shaped and directed downwards, but also clearly outwards over the edge of the ventral edges of the ventral valve, and the copulatory area being more or less detached from the lower edge of the eighth tergite. Male 10th tergum, epiproct, cerci and titillators are shown on
Fig. 10A
1–2
and
Fig. 11B
.
Our record seems to be the second for
Morocco
after
Rungs (1952)
. Most Moroccan records of this species before Nadig’s review refer to other species of the
Finoti
Subgroup (
Nadig 1994
).
Ecology.
The species was observed in a dry ruderalized habitat dominated by bare soil with rare grass, thistles and thorny bushes (
Fig. 1J
). The animals usually kept on
Echinops
sp.
and
Carthamus
sp.
plants. The locality fits desert or semi-desert climate—Köppen climate
type
BSk (Cold semi-arid) to BWk (Cold desert)(
Verner
et al
. 2018
).
