Danilov, Yuriy N., 2015, New and little known digger wasps of the genus Ammophila W. Kirby, 1798 (Hymenoptera: Apoidea: Sphecidae) from Central Asia, Zootaxa 3964 (5), pp. 537-545 : 541-542

Ammophila pevtsovi Danilov sp. nov.

( Figs 1 , 11–13 )

Diagnosis. The female of the new species is most similar to that of the Central Asian A. vetuberosa Li & Yang, 1994 in having an apical tooth on the posterior surface of the forecoxa, but differs in having denser appressed silvery setae of the entire body, all red metasoma, and shiny sculpture of the mesoscutum (in A. vetuberosa the appressed silvery setae of the body are less dense, T5–T6 and S5–S6 of metasoma are black, and the mesoscutum is mat). The male of A. pevtsovi is unknown.

Description. Female. Body length 17 mm. Head. Mandible dark brown. Median lobe of clypeus slightly elongate; black with brown ventral margin ( Fig. 12 ). Clypeus (except ventral margin), face, gena and occiput covered with dense appressed silvery setae. Vertex covered with sparse appressed silvery setae. Erect setae of head white only. Flagellomeres black. Mesosoma . Black; covered with very dense appressed silvery setae, except mesoscutal disk and propodeal enclosure (which are glabrous and shiny). Erect setae white. Mesoscutum shine ( Fig. 13 ). Propodeal enclosure glabrous, obliquely striate. Tegula yellowish. Wings. Hyaline with slightly darker apical part; wing venation light brown; costal vein dark brown. Submarginal cell III petiolate. Legs. Black, pruinose; tarsus brown. Forecoxal apex with tooth. Metasoma. All red.
