Metasoma. Metasoma 0.95 × as long as head and and mesosoma combined (57:60); first metasomal tergite widened apically (Fig. 23), 0.95 × as long as broad (41:43), and 1.5 × as long as propodeum (41:28); first metasomal tergite smooth basally, recticulate medio-apically (Fig. 23), rugo-punctate latero-apically; second tergite with basal area (Fig. 24); median length of second tergite 0.26 × as long as basal width (13:50), and 0.52 × third tergite (13:25) (Fig. 24); hypopygium pointed apically, largely desclerotized, folded basally; setose part of ovipositor sheath 0.7 × as long as hind tibia (23:33).
Color. Largely black; fore leg black, except fore femur yellow latero-ventrally and apically; tibia and tarsus yellow; middle and hind legs black; wing veins blackish brown; fore wing membrane dark brown in apical 0.7 and hyaline in 0.3 of the wing; membrane of hind wing hyaline, except dark apically.
Male: Unknown.
Etymology. From “simulo” (Latin for “imitate”, “copy”), because this new species is similar to A. tujiazu Chen, Whitfield & He, from China.
Biology: Unknown.
Comments. Differences between the new species and A. tujiazu are given in the key. Additionally A. simulatus, sp. n. differs from A. tujiazu by having the following characters: a) Eyes rather densely pilose (Figs 15, 17); b) Median lobe of mesoscutum U-shaped, with long median crenulated depression (Fig. 18); c) Vein 2-SR+M of fore wing 1.4 × as long as vein m-cu; d) First metasomal tergite punctate-reticulate medio-apically (Fig. 23); and e) Setose part of ovipositor sheath 0.7 × as long as hind tibia.
