Ammophila mongolensis TSUNEKI ( Figs 294 , 428 )

Ammophila mongolensis TSUNEKI 1971: 163 , ♀, 3. Holotype: 3, Mongolia: Central Aymag : 3 km E Somon Nalajah (TMB), examined.

M a t e r i a l e x a m i n e d: Holotype 3 ( TMB), 55♀♀, 5433 ( OÖLM), 1♀, 13 ( BMNH), 2♀♀, 233(coll. Jacobs). 733 ( NHMW).

R e c o g n i t i o n Ammophila mongolensis has the submarginal cell III petiolate, the gastral apex black without metallic shine, the propodeal enclosure glabrous and the supra-antennal lamellate projection absent. Additionally, the mesothoracic venter is not prominent anteriorly, the episternal sulcus is extending to the anteroventral margin of the pleuron. The female of A. campestris is similar to A. mongolensis but differs in having the relation of flagellomere I: II = 1.5-1.7, in all specimens a distinct patch of appressed silvery setae on the mesopleuron and the propodeal enclosure shiny ( A. mongolensis has the relation of flagellomere I: II = 1.8-2.1, only in some specimens a small patch of appressed silvery setae on the mesopleuron and in most specimens the propodeal enclosure is dull). The female of A. pubescens differs from A. mongolensis in having the petiole with distinct erect setae ventrally ( A. mongolensis has no erect setae on the petiole ventrally). The male of A. pubescens is similar to A. mongolensis but differs in having a dorsal black stripe on terga I and II and in the shape of gonostyle. The male of A. campestris is similar to A. mongolensis but differs in having a differently shaped gonostyle.

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

♀: 13-16.5. Black except tergum I, gastral segment II and basal half of III red; in some specimens petiole and gastral segments III and IV red. Propodeum posterolaterally and dorsal stripe on hindcoxa and in some specimens small patch on mesopleuron covered with appressed silvery setae; head and prothorax with black erect setae, remaning areas with white ones. Clypeus slightly elongate, ventrally arcuate or with truncate median lobe, disk distinctly convex. Pronotal collar shiny dorsally, lateral lobes finely, transversely striate, scutum dull or shiny, coarsely sparsely punctate and transversely finely striate, scutellum longitudinally striate and punctate. Propodeal enclosure finely, obliquely striate and in most specimens dull. Mesopleuron dull, sparsely punctate; metapleuron and propodeum laterally obliquely punctato-rugose. Flagellomere I: II=1.8- 2.1; length of petiole = hindtarsomeres I+0.25×II to I+0.5×II.

3: 13.5-17 mm. Black except tergum I, gastral segment II and basal half of III red, in some specimens also petiole. Clypeus, frons and propodeum posterolaterally covered with appressed silvery setae. Erect setae on head darkbrown, on thorax and propodeum white. Clypeus slightly elongate and truncate, disk nearly flat. Pronotal collar shiny or dull dorsally, pronotum laterally finely striate. Scutum dull, coarsely punctate and finely transversely striate or rugose, admedian line distinctly developed, scutellum dull, longitudinally striate and coarsely punctate. Propodeal enclosure dull, obliquely striate or irregularly reticulate. Mesopleuron dull, coarsely punctate, metapleuron and propodeum laterally obliquely punctato-rugose. Pronotal collar laterally: Fig. 294 . Gonostyle characteristically shaped: setae on ventral margin of apex nearly as long as those on dorsal margin: Fig. 428 . Flagellomere I: II= 1.4-2.0; length of petiole = hindtarsomeres I+0.5×II to I+II.

G e o g r a p h i c a l d i s t r i b u t i o n: Armenia, central-Turkey, Mongolia, Kazakhstan, Kygyzstan, Tajikistan. Apparently a montaneous species (- 3600m).
