description: Ammophilomima Enderlein, 1914
Ammophilomima Enderlein, 1914: 155. Type species, imitatrix Enderlein by original designation.
Lagynogaster Hermann, 1917: 12. Type species, fuliginosa Hermann by original designation.
Leptogaster (Ammophilomima): Frey (1937): 40.
Leptogaster (Lagynogaster): Frey (1937): 40.
Ammophilomima (Ammophilomima): Oldroyd (1972): 217.
Ammophilomima (Lagynogaster): Oldroyd (1972): 217.
Remarks: Ammophilomima and Lagynogaster were treated as subgenus of Leptogaster by Frey (1937), but Lagynogaster was treated as a synonym of Ammophilomima by Janssens (1953) and Marin (1973). Subsequently Lagynogaster was restored as a valid genus by Nagatomi et al. (2002), herein we treat Lagynogaster as a synonym of Ammophilomima following Dikow (2013).
As Leptogaster trifida has been the only species assigned to Ammophilomima, we do not consider that true Ammophilomima species have previously been recorded from Japan. We have not included Leptogaster trifida since it is not synonymized with Lobus trimucronatus (Ammophilomima trifida) [see above], because we were not able to examine the holotypes.
Generic diagnosis based on character states of Japanese species. Male and female. Head (Figs 5–6, 8–9) black in ground color, 0.3–0.4 times as long as wide; frons yellow tomentose; face white tomentose; ocellar tubercle black, protuberant and asetose; eye height 0.6–0.7 times as long as head width and 1.6–2.0 times as long as head length; mystax with 14–22 setae; occiput yellow tomentose and golden setae; palpus light brown, with golden setae and located at basal 1/5 to 1/6 portion of proboscis; proboscis with short golden setae at apex.
Thorax (Figs 7, 10) yellowish brown or yellowish brown to brown in ground color, yellow tomentose; prosternum and proepisternum fused and prosternum broad above fore coxae; mesonotum shiny (atomentose), with transverse winkles and sparse golden setae and with 3 stripes and without coalescence posteriorly; 1 yellowish brown notopleural seta; 1 yellowish brown supra-alar seta; 2 yellowish brown post-alar setae; postalar callus with yellowish brown setae in dorsolateral; dorsal margin of anepisternum with black or blackish brown stripe extending from anterior thoracic spiracle to base of wing; upper portion of anepisternum, proepimeron and katatergite with sparsely yellow setae; metathoracic spiracle with blackish brown marking and margin surrounded dense yellow micro setae; scutellum with sparse and small black setae on surface, posterior edge of its with small black setae.
Wing (Figs 10–11) hyaline and tinged with yellow; veins brown; most cells with brown microtrichia except cells br and bm; r -m placed at about basal 1/3 of cell d; CuP with distal tubular portion, half as long as CuA 2; cell cu p closed; halter reddish brown.
Leg slender and long, yellow to yellowish brown in ground color; femur with brown or reddish brown setae on apical portion; hind femur with brown marking at middle, golden setose tufts in posterolateral portion; hind tibia with a reddish brown seta at apical 1/3 ventrally; number of short black spines on ventral side of each tarsomere, basitarsus:2nd:3rd:4th:5th = 5:4:4:2:5; ratio of basitarsus/ 2–5 tarsomeres combined, fore:middle:hind = 0.5–0.6:0.5–0.7:0.6–0.8; each tarsomere with small brown marking at apex; tarsal claws black; empodium slightly shorter than tarsal claw.
Abdomen: tergite II with golden hair tufts on both sides dorsolaterally; tergite VIII with golden setae; sternite I to VIII with golden setae; posterior edge of sternite VI and VII with 4–6 golden long setae, approximately 1.3–2.0 times longer than other abdominal setae.
Male genitalia (Figs 13–22). Epandrium with surstylus; upper epandrial lobe longer and wider surstylus (Figs 15, 18); hypandrium subtriangular in ventral view (Figs 14, 17), with sparsely long and pale yellow setae medially; lateral process of gonostylus knife-like in shape; apical 1/4 of gonostylus broad; aedeagus brown and curved in basal half; lateral ejaculatory process moderately curved in dorsal view (Figs 19, 21); ejaculatory apodeme tear-shape (Figs 20, 22).
Spermatheca (Figs 23–24). Furca sclerotized, U-shape; 3 reservoir present with median reservoir larger than lateral reservoirs (Figs 23–24); duct tubular medially.
Ovarian egg (Figs 25–26) subspheric, reddish brown with surface punctate. Diameter approximately 0.4 mm.
Remarks. Generic characters were provided by Martin (1973) and Hull (1962). Japanese species can be distinguished from other Ammophilomima species by following diagnostic character states: head black in ground color; frons golden tomentose; face whitish tomentose; occiput yellowish tomentose; mesonotum with 3 stripes not coalescing posteriorly; wing tinged with yellow; hind femur with brown medial band.
