Ammophila hemilauta KOHL ( Figs 27 , 173 , 205 , 340 , 398 , 460 , 578 )

Ammophila hemilauta KOHL 1906: 360 , ♀. Lectotype: ♀, Tunisia: Médenine (NHMW), examined, present designation.

M a t e r i a l e x a m i n e d: Lectotype ♀ ( NHMW), 3♀♀, 333 ( OÖLM), 4♀♀, 1433 (coll. Schmid-Egger).

R e c o g n i t i o n Ammophila hemilauta has the episternal sulcus extending to the anteroventral margin of the pleuron and the mesothoracic venter not prominent. The propodeal enclosure has irregular, coarse rugae that become oblique laterally and is covered with sparse appressed silvery setae and white erect setae. The female of A. hemilauta differs from A. albotomentosa in having the metapleuron without distinct appressed silvery setae ( A. albotomentosa has the thorax all covered with appressed setae) and in the shape of the clypeus ( Fig. 27 ). The female of A. laevicollis differs from A. hemilauta only in having the free margin of the clypeus sinuate and without a median emargination. The female of A. hemilauta differs from A. nasuta in having the free margin of the clypeus with a median emargination ( Fig. 27 ). The male of A. hemilauta differs from all males of the A. nasuta- group in the shape of the genitalia.

D e s c r i p t i o n: Episternal sulcus extending to anteroventral margin of pleuron, mesothoracic venter not prominent, supra-antennal lamellate projection absent, arolia well defined and claws without basal tooth. Propodeal enclosure with irregular coarse rugae that become oblique laterally, covered with sparse appressed silvery setae and white erect setae.

♀: 17-21.5 mm. Black, with following yellowish-brown: mandible (except apex), free margin of clypeus, fore- and midlegs (except coxa), hindtibia (all or basal half), tegula, petiole partly, tergum I (dorsally black) and gastral segments II- IV; segments V and VI black with poor metallic shine. Head (except vertex), thorax (except metapleuron) and propodeum covered with appressed silvery setae; in most specimens appressed setae lack on pronotal collar dorsally, scutum medially and scutellum. Clypeus distinctly elongate, emarginate medially ( Fig. 27 ), disk markedly convex, lower third of clypeal bulge almost inpunctate, shiny and glabrous. Vertex smooth and shiny, also pronotal collar dorsally. Scutum coarsely punctate, shortly transversely ridged, scutellum longitudinally ridged and punctate. Metapleuron densely coarsely punctate, without dense, appressed silvery setae. Pronotal collar laterally: Fig. 173 . Flagellomere I: II=1.6-2.0; length of petiole = hindtarsomeres I+II to I+II+0.75×III.

3: 16-18 mm. Black, with following yellowish-brown: mandible (except apex; in some specimens all black), tegula, fore- and midlegs (except coxa), basal half of hindtibia, petiole partly, tergum I (except for black dorsal stripe), gastral segments III- VII (in most specimens terga V and VI black dorsally). Head (except vertex), thorax (except metapleuron) and propodeum covered with appressed silvery setae; erect setae whitish. Vertex nearly impunctate. Clypeus distinctly elongate, narrowing ventrally, medially emarginate ( Fig. 205 ), disk in ventral half concave, in dorsal half distinctly convex ( Fig. 340 ). Pronotal collar sparsely punctate, scutum densely, coarsely punctate, scutellum longitudinally ridged and punctate. Labrum with erect spine on apical margin. Gonostlye laterally: Fig. 398 ; penisvalve laterally: Fig. 460 , apically: Fig. 578 ; sternum VIII emarginate medially. Flagellomere I: II=1.7-2.3; length of petiole = hindtarsomeres I+II to I+II+0.6×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: Egypt, Israel, Libya, Tunisia, Morocco.
