R e c o g n i t i o n Ammophila djaouak has a gastral apex without metallic shine, the mesothoracic venter not prominent anteriorly and the episternal sulcus extending to the anteroventral margin of the pleuron. The male of A. hemilauta differs from A. djaouak in having the inner margin of the mandible with two subapical teeth and no basal tooth, the labrum with a spine on the anterior margin and the shape of the gonostyle ( Fig. 398 ) and the penis valve ( Figs 460 , 578 ) ( A. djaouak has one subapical tooth on the inner margin of the mandible and one blunt basal tooth, and the labrum has no spine). The male of A. albotomentosa differs from A. djaouak in having the clypeus less elongate ( Fig. 225 ), the thorax covered with dense appressed silvery setae that obscure the underlying sculpture and in characteristically shaped gonostyle ( Fig. 385 ) and penis valve ( Fig. 456 ) ( A. djaouak has a thorax with appressed silvery setae that not obscure the underlying sculpture).

D e s c r i p t i o n 3: 20-21.5 mm. Gastral apex without metallic shine, mesothoracic venter not prominent anteriorly, episternal sulcus extending to anteroventral margin of pleuron, arolia large and claws without basal tooth. Black, with following yellowishbrown: mandible (except apex), tegula, fore- and midlegs (except coxa), hindfemur apically, hindtibia (except apically), petiole (dorsally darkened), tergum I (except for black dorsal stripe) and remaning areas of gaster (except some dark spots). Head, thorax and propodeum covered with appressed silvery setae that do not obscure sculpture on pronotal collar, scutum and metanotum; erect setae whitish. Inner margin of mandible with one subapical tooth and one blunt basal tooth; supra-antennal lamellate projection slightly developed. Ventral margin of clypeus elongate, narrowed and emarginated medially ( Fig. 226 ), disk concave on ventral half and convex on dorsal half ( Fig. 341 ), labrum anteriorly armed with preapical spine. Pronotal collar slightly punctate, not transversely ridged. Scutum distinctly transversely punctato-rugose, scutellum punctate and longitudinally striate. Propodeal enclosure irregularly coarsely rugose, covered with sparse appressed silvery setae and with erect setae. Genitalia characteristically shaped: gonostyle laterally: Fig. 399 ; penis valve laterally: Fig. 462 , ventrally: Fig. 521 and apically: Fig. 580 . Sternum VIII slightly emarginate. Flagellomere I: II=1.7; length of petiole = hindtarsomeres I+II+0.3×III.

♀ unknown.
