D i s c u s s i o n. The female of
L. ajjer
was not described yet. The species was only known by males from the inner Sahara. I could examine a female of the
L. ajjer
species group from southern
Morocco
which represent most probable the female of
L. ajjer
. It agrees with the male description, but
Laphyragogus
males and females differ markedly in colour, so the male-female association is provisional. Annother hint gives the zoogeografic distribution pattern: the finding location of the female in the extrem south of
Morocco
close to the Algerian border belongs to the "inner Saharian" distribution pattern. Other species with a similar distribution, as
Bembecinus mhamidus
SCHMIDEGGER, 2004
, described close from the present finding place of
L. ajjer
in Mhamid, as well as from
Mauritania
and
Mali
(SCHMID-
EGGER 2004
) also occur in this area. So, such a distribution pattern (Tassili des Ajjer – Zagora area) is not unlikely, also taken the large distance of about 1400 kilometers between the
type
area and Zagora into account.
D i a g n o s i s
L. ajjer
belongs to the
L. ajjer
species group. The lateral spine of S6 of males is shorter in
L ajjer
compared with
L. orientalis
, and similar to that of
L. gessi
. Yellow colour of mesosoma is more extended in
L. ajjer
compared with
L. gessi
. Females can only be recognized by colour pattern, see description and key.

AS
1-2, pronotum except black transverse medial band, two large longitudinal spots on mesoscutum, scutellum except medial black spot, metapleural flange (sensu BOHART & MENKE 1976: 11), metanotum (colour withishyellow), two spots on propodeal dorsum laterally behind, propodeum laterally, small spot on mesopleuron anteriorly, legs (with some darker yellow parts). Abdomen reddish, with large apical whitish bands on T1 and T5, and some indistinct pale spots on following tergites. T6 reddish-yellowish. Face and propodeum covered with long, silver pilosity, on face appressed, on propodeum semi-erect. Tegula, wing base and wing venation yellow, wings transparent. Morphology: Mandible basally with pointed tooth short before midpoint. Head very large, 1,4x as wide as long. Apical process of foremetatarsus 1.6x as long as remaining tarsus, tarsal segments II and III apically with small process. Mesopleuron without any punctation, more or less smooth. Mesonotum smooth, with some large punctures laterally, and some smaller punctures mediolaterally, medially with longitudinal emargination and rugose sculpture. Scutellum and metanotum with fine, scattered punctation, punctures 1-5 diameters apart. Propodeal dorsum grainlike sculptured. T1-4 with very fine and dense grainlike sculpture, T5-6 shiny, with a few large and scattered punctures. Sternites shiny, laterally with dense punctation, medially punctless. T6 laterally concave, apically truncate-rounded. Basal triangular platform of T6 with shiny and rugulose surface.
