R e c o g n i t i o n Ammophila pubescens has a submarginal cell III petiolate, the gastral apex black without metallic shine, the supra-antennal lamellate projection absent and the propodeal enclosure glabrous. The erect setae are black. The female differs from A. campestris in having the petiole ventrally with distinct erect setae and the propodeal enclosure obliquely striate and micropunctate ( A. campestris has the petiole without erect setae ventrally and the propodeal enclosure is shiny). The female of A. afghanica is similar to A. pubescens but differs in having the clypeus and the frons covered with distinct, appressed silvery setae, the erect setae on the head are white, and the scutum is shiny with transverse striae ( A. pubescens has no distinct, appressed silvery setae on the clypeus and frons and the scutum is dull). The male of A. pubescens differs from A. campestris in having a dorsal black stripe on terga I and II, the propodeal enclosure micropunctate and in most specimens the petiole ventrally with erect setae ( A. campestris has terga I and II all red and the propodeal enclosure shiny).

D e s c r i p t i o n: Submarginal cell III petiolate, gastral apex black without metallic shine, supra-antennal lamellate projection absent, mesothoracic venter not prominent anteriorly and episternal sulcus extending to anteroventral margin of pleuron. Propodeal enclosure glabrous, arolia well defined and claws without basal tooth.

♀: 15-19 mm. Black except tergum I (except basally), gastral segment II and the basal half of III red. Pronotal lobe, patch along mesopleural suture and propodeum posterolaterally covered with appressed silvery setae. In some specimens clypeus and frons pruinose. Erect setae on head black, on remaning areas brown to white. Clypeus slightly elongate with distinct median lobe, disk slightly convex. Pronotal collar dull and sparsely, finely punctate, scutum dull and punctate (punctures 0-2 diameters apart), laterally transversely microstriate; scutellum longitudinally striate. Mesopleuron dull, irregularly punctate, metapleuron and propodeum laterally dull and punctato-rugose. Propodeal enclosure obliquely striate, micropunctate between striae. Petiole ventrally with distinct, erect setae. Flagellomere I: II=1.5-1.7(2.0); length of petiole = hindtarsomeres I+0.3×II to I+0.5×II.

3: 12.5-18 mm. Black except terga I and II (except for dorsal black stripe) red, in some specimens gaster nearly all black. Clypeus, frons and propodeum posterlaterally covered with distinct appressed silvery setae. In some specimens mesopleuron, pronotal lobe, propodeum laterally and hindcoxa pruinose. Erect setae on head black, on remaning areas white, sterna VII and VIII covered with appressed brown setae. In most specimens petiole ventrally with erect setae. Clypeus slightly elongate, disk nearly flat. Pronotal collar dull, nearly impunctate, scutum dull, transversely microstriate, scutellum longitudinally striate. Mesopleuron, metapleuron and propodeum laterally dull, irregularly punctate (punctures 0-3 diameters apart); propodeal enclosure obliquely striate and micropunctate. Pronotal lobe laterally: Fig. 293 . Gonostyle laterally: Fig. 426 ; penis valve laterally: Fig. 490 , ventrally: Fig. 548 , apically: Fig. 598 . Flagellomere I: II=1.4-1.6; length of petiole = hindtarsomeres I+0.75×II to I+II.
