Ammophila tsunekii MENKE ( Figs 76 , 171 , 412 , 489 , 547 )

Ammophila tomentosa TSUNEKI 1971: 174 , ♀, junior secondary homonym of Ammophila tomentosa (ARNOLD 1920) . Holotype: ♀, Mongolia: Central Gobi Aymag : Hoot bulag (TMB), examined.

Ammophila tsunekii MENKE in BOHART & MENKE 1976: 154. Substitute name for Ammophila

tomentosa TSUNEKI. M a t e r i a l e x a m i n e d: 18♀♀, 4133 (OÖLM).

R e c o g n i t i o n Ammophila tsunekii has the gastral apex bluish-black with metallic shine, the propodeal enclosure glabrous and the mesothoracic venter not prominent anteriorly. In addition, the following are covered with appressed silvery setae that obscure the underlying sculpture: the head (except a small spot on the free margin of the clypeus and the vertex), the thorax (except the metapleuron) and the propodeum (except dorsal enclosure). In most collection specimens the appressed setae are damaged on the dorsal face of the pronotal collar, the scutum and the scutellum; remarkable is the sharp limit to the glabrous parts. Both sexes of A. tsunekii are similar to A. terminata but differ in having much denser appressed, silvery setae on the head, the thorax and the propodeum.

D e s c r i p t i o n: Gastral apex bluish-black, with metallic shine, propodeal enclosure glabrous, mesothoracic venter not prominent anteriorly, episternal sulcus extending to anteroventral margin of pleuron, arolia distinctly developed and claws without basal tooth. Following covered with appressed, silvery setae that obscure underlying sculpture: head (except small spot on free margin of clypeus and vertex), thorax (except metapleuron) and propodeum (except dorsal enclosure). In most collection specimens appressed setae damaged on dorsal face of pronotal collar, scutum and scutellum; remarkably sharp limit to glabrous parts. Pronotal collar shiny, smooth, without distinct transverse striae (at most transversely microstriate); scutum also shiny, with deep admedian line and with fine short striae laterally; scutellum longitudinally striate. Propodeal enclosure obliquely striate and in some specimens micropunctate between the striae.

♀: 13-17 mm. Black except tergum I and gastral segments II-IV red. Clypeus slightly elongate, free margin truncate ( Fig. 76 ), disk slightly convex. Pronotal collar laterally: Fig. 171 . Flagellomere I: II=1.6 -1.9; length of petiole = hindtarsomeres I+0.6×II to I+0.75×II.

3: 14.5-17 mm. Black except tergum I and gastral segments II-IV red. Gonostyle laterally: Fig. 412 ; penis valve laterally: Fig. 489 , ventrally: Fig. 547 . Flagellomere I: II=1.5-1.6; length of petiole = hindtarsomeres I+II to I+II+0.3×III.

G e o g r a p h i c a l d i s t r i b u t i o n: Mongolia.
