Ammophila dentigera GUSSAKOVSKIJ (Figs 25, 47, 122, 142, 212, 276, 316, 347, 407)

Ammophila dentigera GUSSAKOVSKIJ 1928: 8 , ♀, 3. Paratypes: ♀, 3 Uzbekistan: Khiva (ZIN),

examined. M a t e r i a l e x a m i n e d Paratypes 1♀, 13 ( ZIN) ; Kazakhstan: Aralsk city env. (13

OÖLM), S Balkhash lake 6 km E Mulaly (13 OÖLM), Tshilik riv. 3 km E Borandyser Masak (13 OÖLM), Charyn valley W Chundsa (13 coll. Schmid-Egger). Turkmenistan: 15 km N Ashabat (433 OÖLM). Uzbekistan: Kyzil-Kum desert Uchkuduk (1♀ OÖLM).

R e c o g n i t i o n Ammophila dentigera has the gastral apex black without a metallic shine, the mesothoracic venter anteriorly prominent, with a transverse carina that in most specimens forms a median projection, additionally the forecoxa has a medioventral acute tooth (Fig. 25). The pronotal collar is nearly as long as posteriorly broad and without rugae ( Figs 122 , 142 , 276 , 316 ). The female of A. tekkensis differs from A. dentigera in having the clypeus not distinctly elongate and the mesothoracic venter anteriorly with a transverse carina that forms one projection on each side and a forecoxa without a medioventral tooth. The female of A. induta is similar to A. dentigera , but differs in having the mesothoracic venter not prominent, the forecoxa lacks an acute tooth and the propodeal enclosure along the midline is covered with appressed silvery setae, glabrous and finely, obliquely striate laterally ( A. dentigera has the propodeal enclosure all covered with appressed silvery setae). The female of A. dentigera differs from A. producticollis in having a mesothoracic venter anteriorly prominent with a transverse carina that in most specimens forms one median projection and in having a forecoxa with an acute tooth (Fig. 25). The male of A. guichardi differs from A. dentigera in having a mesothoracic venter anteriorly not prominent, the forecoxa without an acute tooth, in the shape of gonostyle laterally ( Fig. 380 ) and penis valve laterally ( Fig. 450 ). The male of A. producticollis differs from A. dentigera in having a mesothoracic venter not prominent anteriorly, the forecoxa without an acute tooth and a clypeal disk distinctly convex ( Fig. 344 ). The male of A. induta is similar to A. dentigera but differs in having a mesothoracic venter anteriorly not prominent and the forecoxa without an acute tooth.

D e s c r i p t i o n: Gastral apex black, without metallic shine, mesothoracic venter anteriorly prominent, with transverse carina that in most specimens forms median projection, forecoxa with medioventral acute tooth (Fig. 25) and supra-antennal lamellate projection absent. Episternal sulcus extending to anteroventral margin of pleuron, arolia distinct and claws without basal tooth. Head (except of vertex), thorax and propodeum (including propodeal enclosure) all covered with appressed silvery setae; erect setae white and wings hyaline. Pronotal collar nearly as long as posteriorly broad and without rugae ( Figs 122 , 142 , 276 , 316 ), scutum sculptured similarly as collar, admedian line nearly lacking and scutellum with two longitudinal rugae.

♀: 15-16 mm. Black, with following yellowish-brown: mandible (except of apex), free margin of clypeus, scape, pedicel, tegula, fore- and midlegs, hindlegs (coxa, trochanter and femur darkened dorsally) and gaster (partly darkened). Clypeus elongate, with broad median lobe ( Fig. 47 ). Flagellomere I: II =1.6; length of petiole = hindtarsomeres I+II.

3: 14-18.5 mm. Black, with following yellowish-brown: mandible (except of apex), clypeus adjacent to free margin, apical spot on scape, tegula, legs (partly darkened) and gaster (in some specimens nearly all dark-brown); petiole dark brown. Clypeus elongate, with median lobe truncate or slightly emarginate ( Fig. 212 ), disk slightly convex ( Fig. 347 ). Propodeal enclosure transversely striate and petiole distinctly longer then tergum I (8: 6). Pronotal collar laterally: Fig. 276 , dorsally: Fig. 316 . Gonostyle laterally with long erect setae on dorsal and ventral surfaces ( Fig. 407 ). Flagellomere I: II=1.0-1.4; length of petiole = hindtarsomeres I+II+0.5×III to I+II+0.75×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: Afghanistan, Iran, Kazakhstan, Tajikistan, Turkmenistan, Uzbekistan.
