Ammophila vetuberosa Li & Yang, 1994

( Figs 1 , 14–16 )

Ammophila vetuberosa Li & Yang in Li, Li & Yang 1994: 290, ♂. Holotype: ♂, China: Shandong Province: Dongying City: Xianthe Town (SDAU), not examined.

Ammophila vetuberosa: Dollfuss 2013a: 403 , 501, 564; Pulawski 2015.

Diagnosis. The male and the hitherto unknown female of A. vetuberosa differ from all species with a petiolate submarginal cell III (except A. pevtsovi ) in having an apical tooth on the forecoxa. The female of A. vetuberosa is most similar to that of the Central Asian A. pevtsovi sp.nov., but differs in having less dense appressed silvery setae of the body, T5–T6 and S5–S6 of the metasoma black, and a mat mesoscutum (in A. pevtsovi the appressed silvery setae of body are denser, the metasoma is all red, and the mesoscutum is shiny).

Description. Female (hitherto unknown). Body length 15–18 mm. Head. Mandible brown. Median lobe of clypeus slightly elongate ( Fig. 16 ). Clypeus (except ventral margin), subantennal area and paraocular area covered with dense appressed silvery setae; frons, vertex, gena and occiput covered with sparse appressed silvery setae. Erect setae of head white. Flagellomeres black. Mesosoma . Pronotum and mesoscutum smooth, covered with sparse appressed silvery setae. Pronotal lobe covered with dense appressed silvery setae. Mesopleuron covered with dense appressed silvery setae. Metapleuron covered with sparse appressed silvery setae. Propodeum only posterolaterally covered with dense appressed silvery setae. Erect setae white. Propodeal enclosure glabrous, obliquely striate. Tegula brownish. Wings. Hyaline with slightly darker apical part; wing venation brown; costal vein black. Submarginal cell III petiolate. Legs. Black, pruinose. Forecoxa with apical tooth. Metasoma. T1–T4 and S1–S4 red, T5–T6 and S5–S6 black (sometimes T4 black).

Male. Body length 16 mm. Head. Mandible black. Clypeus, frons covered with dense appressed silvery setae. Erect setae of head white. Flagellomeres black. Mesosoma . Pronotal lobe, patch on mesopleuron and propodeum posterolaterally covered with dense appressed silvery setae. Propodeal enclosure glabrous, obliquely striate. Wings. Hyaline with slightly darker apical part; wing venation brown; costal vein black. Submarginal cell III petiolate. Legs. Black, pruinose. Forecoxa with apical tooth. Metasoma. T1–T3 and S2–S4 red, T4–T7 and S5–S7 black (sometimes part of T5 black).

Material examined. China: 1 ♂, Nei Menggu, Alxa prefecture, Ejin [100º35'E 42º00'N], 20.VII.1886, G.N. Potanin ( ZISP). 1 ♀, Nei Menggu, Alxa prefecture [105º40'E 38º49'N], 30.VI.1908, P.K. Kozlov ( ZISP). 1 ♀, Ningxia, Yinchuan [106º16'E 38º28'N], 5.VI.1908, P.K. Kozlov ( ZISP). 1 ♀, Gansu, Jiuquan prefecture, Jinta County [99º04'E 40º13'N], 6.VII.1886, G.N. Potanin ( ZISP). Mongolia: 2 ♂, Bayankhongor Province, Orog Nuur lake [100º30'E 45º05'N], 13.VIII.1926, A.N. Kirichenko ( ZISP). Russia: 1 ♀, East Siberia, Irkutsk Oblast, Usolsky District, Mal’ta [103º31'E 52º50'N], 26.VI.1907, D.A. Smirnov ( ZISP).

Distribution. China: Shandong (Li, Li & Yang 1994), *Ningxia, *Gansu, Nei Menggu ( Dollfuss 2013a); * Mongolia: Bayankhongor; * Russia: Irkutsk Oblast.

Remarks. Ammophila vetuberosa was described by Li and Yang (1994) based on a male collected in Shandong Province ( China). Dollfuss (2013a) in a revision of Palearctic and Indian Ammophila redescribed the male and provided new data on the distribution from Ordos ( China: Nei Menggu [not Mongolia, as stated by Dollfuss 2013a: 501]). During the study of Ammophila in ZISP, the males of Ammophila vetuberosa collected by G.N. Potanin, P.K. Kozlov and A.N. Kirichenko in China and Mongolia were found, as well as the hitherto unknown female with an apical tooth on the forecoxa that is described above.
