R e c o g n i t i o n Ammophila infesta has the gastral apex black-bluish with a slight metallic shine (in some specimens nearly black), the supra-antennal lamellate projection well developed (higher than the diameter of the midocellus), the mesothoracic venter not prominent anteriorly, the episternal sulcus extending to the anteroventral margin of the pleuron. The female of A. infesta is similar to A. sabulosa but differs in having a more developed supra-antennal lamellate projection (higher than the diameter of the foreocellus) and the propodeal enclosure covered with erect setae medially, glabrous laterally. Additionally, the scutum and the mesopleuron are smooth or micropunctate, finely and more or less regularly punctate, punctures well defined, never confluent (punctures more than one diameter apart). The female of A. sickmanni is similar to A. infesta but differs in having the gastral apex without a metallic shine and the scutum distinctly transversely rugose. The female of A. formosensis differs from A. infesta in having the clypeus, the frons, the pronotal lobe, the mesopleuron and the propodeum posterolaterally covered with appressed silvery setae and the propodeal enclosure all covered with erect setae ( A. infesta has only the posterior part of the pronotal lobe covered with appressed silvery setae and the propodeal enclosure laterally glabrous). The female of A. vagabunda differs from A. infesta in having the scutum and the mesopleuron rugose and coarsely punctate (punctures partly confluent) ( A. infesta has the scutum smooth or micropunctate, macropunctures well defined, never confluent). The male of A. infesta is similar to A. sickmanni but differs in having the gastral apex with blue-black slightly metallic shine, the scutum punctate and at most laterally slightly transversely striate ( A. sickmanni has the gastral apex black and the scutum coarsely, transversely ridged). The male of A. infesta is similar to A. sabulosa but differs in having the supra-antennal lamellate projection more developed (higher than the diameter of the midocellus) and the propodeal enclosure reticulate and covered with erect setae medially, obliquely ridged and glabrous laterally ( A. sabulosa has the supra-antennal projection less developed (Fig. 20) and the propodeal enclosure all covered with erect setae).

D e s c r i p t i o n: Gastral apex black-bluish with slight metallic shine (in some specimens nearly black), supra-antennal lamellate projection well developed (higher than diameter of midocellus), mesothoracic venter not prominent anteriorly, episternal sulcus extending to anteroventral margin of pleuron, arolia large and claws without basal tooth.

♀: 20-27 mm. Black except tergum I (partly) and gastral segment II red (in some specimens only segment II red). Posterior part of pronotal lobe covered with appressed silvery setae; erect setae on head dark-brown, those on propodeum white. Clypeus slightly elongate, median lobe laterally delimited by small tooth ( Fig. 64 ), disk distinctly convex. Pronotal collar smooth, impunctate dorsally ( Fig. 156 ). Scutum and mesopleuron smooth or micropunctate, finely and more or less regularly punctate, punctures well defined, not confluent (punctures more than one diameter apart). Scutellum on anterior half smooth and punctate, on posterior half longitudinally striate. Propodeal enclosure obliquely ridged, covered with erect white setae medially, glabrous laterally. Flagellomere I: II=1.6-1.8; length of petiole = hindtarsomeres I+0.5×II.

3: 17-25 mm. Black, except tergum I and gastral segment II red (both except for black dorsal stripe); in some males tergum I all black. Clypeus, frons, posterior part of pronotal lobe, small patch along mesopleural suture and propodeum posterolaterally covered with appressed silvery setae; erect setae white. Clypeus elongate ( Fig. 215 ), disk nearly flat ( Fig. 350 ); vertex dull, nearly impunctate. Pronotal collar dull, sparsely punctate, scutum dull, irregularly punctate (punctures 0-3 diameters apart), in some specimens laterally slightly, shortly ridged; scutellum longitudinally ridged. Propodeal enclosure along midline reticulate and covered with erect setae, laterally obliquely ridged and glabrous. Mesopleuron distinctly coarsely punctate (punctures 0-2 diameters apart), not transversely rugose. Flagellomere I: II=1.2-1.4; length of petiole = hindtarsomeres I+II.
