Ammophila pseudoheydeni LI & HE ( Figs 725-733 )

Ammophila pseudoheydeni LI & HE 2000: 337 , ♀, 3. Holotype: ♀, China: Xinjiang: Wulumuqui at 43.8°N 87.6°E (Zhejiang Agricultural University ), not examined.

M a t e r i a l e x a m i n e d:None.

D e s c r i p t i o n (LI & HE 2000: 337): " ♀: Body length 15-21 mm. Black; basal half of mandible, clypeus next to free margin, antenna partly, tegula, legs largely or wholly, gastral petiole, terga I-IV and sterna II-IV yellowish red; tergum V and sternum V yellowish red or all black; gastral apex black with weak metallic blue luster; wings pale yellowish brown, veins yellowish brown or brown. Clypeus except free margin, lower frons, gena, pronotum laterally including pronotal lobe, scutum posterolaterally, prepectus, mesopleuron and propodeum posterolaterally covered with dense appressed silvery setae; collar, anterior half of scutum, scutellum laterally and metanotum laterally, propodeum, sterna of thorax and coxae with appressed silvery setae; head and thorax with long, erect, white setae. Clypeus densely punctate, free margin with two lateral teeth ( Fig. 725 ). Frons densely punctate, without distinct supra-antennal projection. Vertex sparsely punctate. Postocellar distance (POD): oculocellar distance (OOD): interocular distance at anterior ocellus (IODP): interocular distance at clypeus (IODC) = 21: 29: 96: 82. Relative length of antennal pedicel: flagellomeres I: II: III: VIII: IX = 15: 51: 31: 31: 22: 21. Pronotal collar ( Fig. 726 ) length: width = 50: 87, densely punctate, with shallow median furrow, weakly transversely rugose-striate on anterior slope. Scutum with complete admedian line, side of anterior half transversely rugose-striate and punctate, medial region of posterior half longitudinally rugose-striate. Scutellum longitudinally rugose-striate and punctate. Metanotum sparsely punctate. Mesopleuron with episternal sulcus, other structures covered by dense appressed silvery setae. Metapleuron coarsely, irregularly rugose-striate. Propodeal enclosure with weak median carina, surface irregularly obliquely rugose-striate laterally; lateral side of propodeum coarsely, irregularly rugose-striate. Submarginal cell III without petiole ( Fig. 730 ). Tarsomere I of foreleg with seven large setae ( Fig. 728 ); hindleg: relative length of tibia: tarsomere I: II: III = 215: 119: 65: 50. Length of gastral petiole: tergite I: II = 195: 177: 135.

3: Body length 17.0- 18.8 mm. Similar to female. Clypeus black, mandible reddishbrown or black, antenna dark brown or black. Free margin of clypeus emarginate medially. POD: OOD: IODP: IODC = 22: 31: 100: 58. Relative length of antennal pedicel: flagellomeres I: II: III: VIII: IX = 14: 48: 35: 35: 21: 20. Pronotal collar length: width = 40: 90, without median furrow. Posterior half of scutum not rugose-striate. Propodeal enclosure reticulate-striate medially, rugose-striate laterally. Hindleg: relative length of tibia: tarsomere I: II: III =232: 118: 64: 50. Length of gastral petiole: terga I: II = 200: 190: 139. Genitalia with penis valves as in Fig. 731 , volsella as in in Fig. 732 and gonostyli as in Fig. 733.

R e l a t i o n s h i p s: This species is related to A. heydeni DAHLBOM , but differs by the shape of the anterior margin of clypeus, the sculpture of scutum and propodeal enclosure as outlined in the text, gastral petiole longer than hindtarsomeres I + II and in male only 1/5-1/6 shorter than the hindtibia, coloration of body, appressed silvery setae on head and thorax, and by the male genitalia."
