Ammophila exsecta KOHL ( Figs 43 , 115 , 138 )

Ammophila propinqua var. exsecta KOHL 1906: 364 , ♀. Holotype: ♀, Syria: no specific locality (NHMW), examined.

M a t e r i a l e x a m i n e d: Holotype ♀ ( NHMW); Syria: no specific locality (13 NHMW). Jordan: Jordan Valley Mubalath (1♀ OÖLM). Oman: N Nizwa Jabal Akdar Massif (2♀♀ coll. Schmid-Egger).

R e c o g n i t i o n:Bothsexesof A. exsecta are similar to A. rubripes and differ only in having the anterior surface of the pronotal collar concave in lateral view (fig. 138) ( A. rubripes has the anterior surface of the pronotum evenly rounded).

D e s c r i p t i o n: Gastral apex black without metallic shine, supra-antennal lamellate projection absent, mesothoracic venter not prominent anteriorly, episternal sulcus extending to anteroventral margin of pleuron, arolia well developed and claws without basal tooth.

♀: 18-21.5 mm. Black, with following more or less variably red: mandible (except apex), ventral half of clypeal disk, anterior face of scape, pronotal collar (dorsally narrow, laterally broader), tegula, petiole (dorsally black), tergum I (basally black), gastral segments II-III (IV), legs (except hindcoxa dorsally and mid- and hindfemora). Head (except clypeus ventral half and vertex), thorax, propodeum and coxa evenly covered with appressed silvery setae; pronotal collar dorsally, scutum and propodeal enclosure pruinose. Erect setae on head, thorax and propodeum (including propodeal enclosure) whitish. Clypeus elongate ( Fig. 43 ), ventral half coarsely, sparsely punctate and glabrous, dorsal half covered with dense appressed silvery setae, disk distinctly convex. Pronotal collar in lateral view with concave anterior surface ( Figs 115 , 138 ), dorsally impunctate and shiny. Scutum punctate and transversely striate, scutellum coarsely punctate and longitudinally ridged. On mesopleuron, metapleuron and propodeum laterally sculpture obscured by appressed silvery setae. Propodeal enclosure coarsely transversely ridged, setose. Flagellomere I: II=1.5-1.7; length of the petiole = hindtarsomeres I+II+0.3×III to I+II+0.5×III.

3: 19 mm. Black, with following red: mandible (except apex), pronotal lobe, pronotal collar dorsally (except small patch anteriorly), fore- and midlegs, hindleg (coxa, trochanter and femur dorsally black), petiole, tergum I (dorsally black), terga II and III (dorsally black) and sterna II-V. Head (except vertex), pronotal lobe, mesopleuron, metapleuron and propodeum laterally covered with appressed silvery setae. Pronotal collar, scutum, scutellum and propodeal enclosure and legs pruinose; erect setae whitish. Clypeus slightly elongate, disk convex. Pronotal collar in lateral view on anterior half slightly concave as in female ( Fig. 138 ). Scutum distinctly transversely striate, scutellum obliquely striate and punctate and propodeal enclosure transversely striate, setose. Genitalia as in A. rubripes . Flagellomere I. II=1.5; length of petiole = hindtarsomeres I+II+0.5×III.

G e o g r a p h i c a l d i s t r i b u t i o n: Jordan, Syria, Oman.
