Description. Holotype. Female. Body length 2.4 mm, fore wing length 2.9 mm.
Head. Transverse in dorsal view, 2.1× as wide as long, as wide as mesoscutum. Vertex between eye and posterior ocellus highly shiny with very superficial punctures. Temple slightly shiny with shallow punctures, with fine aciculation at bottom, strongly constricted. Face 0.8× as high as wide, shiny with shallow, small punctures, inner margin of eyes parallel-sided. Ocelli not small, posterior tangent to anterior ocellus touching posterior ocelli, distance between fore and hind ocellus slightly shorter than diameter of hind ocellus, POL:OD:OOL=3.5:2.0:4.2. Antenna slightly shorter than body length, closely articulated, penultimate flagellomere cubic.
Mesosoma. Length:width:height = 41.5:27.0:28.0. Disc of mesonotum distinctly wider than long, dull with coarse punctures, interspaces not larger than diameter of puncture, somewhat confluently punctate at posterior end of notaulic courses, without longitudinal striations. Scutellar sulcus nearly straight, narrow with carinae inside. Scutellum highly shiny and smooth entirely, median length not longer than basal width, flattened and widened behind. Lateral polished field of scutellum reaching over half length of scutellum. Propodeum slightly shiny, with small, strong punctures anterio-laterally, areola incomplete with V-shaped apex, medial keel indefinite but long, costulae absent, spiracle enclosed by keel behind, on each side of areola tends to become smoother and scattered some punctures laterally, and with irregular short carinae behind spiracle. Mesopleuron shiny, anterior most parts shallowly punctate, its margin rugulose-punctate.
Legs. Hind femur relatively thin, 3.0× longer than wide. Hind coxa weakly dull with indefinite punctures above (basally). Spines on outer side of third tibia acuminated, relatively dense. Inner spurs of hind tibia 2/5 length of hind basitarsus, outer spur 1/4. Basitarsus of hind leg weakly longer than tarsomeres 2–4 combined (20.0:18.5), claws of normal size.
Wings. Pterostigma 3.2× as long as its widest part. Vein 1-R1 1.2× longer than pterostigma, 3.6× as long as its distance from apex of marginal cell. Vein r arising from middle of pterostigma, nearly perpendicular to the latter, weakly longer than width of pterostigma, r 1.5× 2 longer than SR, indistinctly angled at junction, 2-M 2/3 as long as 2-SR, as long as 1-SR, 2-SR+M slightly longer than 2-M, cu-a as long as width of pterostigma. First discal cell of fore wing much wider, weakly wider than high. Second submarginal cell of hind wing 1.6× wider than high. Vein cu-a strongly curved. Hind wing broad, length of 1-M slightly shorter than distance between its distal extremity and apex of vannal lobe, and vannal lobe beyond its widest part concave and hairless.
Metasoma. As long as mesosoma. T1 nearly parallel-sided anteriorly, but weakly converged at apical third, 2.1× longer than hind width, concave at basal two-fifths, turned-over part dull, strongly rugose, and scattered some punctures, longitudinal trough shallow, and apical tubercle shiny and polished. T2 not shiny, rough with some punctures laterally, 3.5× wider than long in the middle, weakly curved into T3 apically. T3 1.9× longer than T2. Tergites posterior to T2 shiny, smooth and pubescent. Hypopygium not longer than apex of metasoma. Ovipositor sheath 1.9× longer than length of hind tibia, relatively narrow, ovipositor without apical attenuation, mostly straight, slightly curved at apex.
Colour. Black. Tegula dark brown. Palpi and spurs pale yellowish. Antenna and ovipositor sheath dark brown. Labrum and mandible reddish brown. Legs dark brown, except most part of fore femur, fore tibia with tarsus (apical several segments brownish), apex of mid femur, basal third of mid tibia with tarsus and basal third of hind tibia yellow. Wing membrane hyaline, C+SC+R, 1-R1, border of pterostigma, r, 2-SR and 2-M brown, other alar veins more or less pale, pterostigma pallid with dark border.
Variation. Body length 2.4–2.7 mm, fore wing length 2.9–3.3 mm. Body of a specimen reddish brown entirely, and propodeum shinier and smooth.
Male. Unknown.
Material examined. Holotype: 1♀, Hangzhou , Zhejiang, 1989.X.6, He Junhua, No. 896176 . Paratypes: 1♀, Guadun, Mt. Wuyi , Fujian, 1994.VII.15, Xu Zaifu, No. 942815 ; 1♀, Yuhuangshan, Hangzhou , Zhejiang, 2003. VII.20, Wu Qiong, No. 20057269 ; 1♀, Qingliangfeng, Lin’an , Zhejiang, 2005.VIII.11, Shi Min, No. 200607537 .
Distribution. China (Fujian, Zhejiang).
Etymology. The specific name “ fundum ” derives from the Latin verb “fundo” and suffix “-um”, referring to the presence of long medial keel on propodeum.
Remarks. This species is similar to A. angaleti Muesebeck , but differs in the following: ovipositor sheath nearly 2.0× longer than hind tibia (shorter, about one and a half in latter); metacarp 3.6× longer than its distance from apex of marginal cell (fully five times in latter); and propodeum somewhat shiny and smooth (with dull, rather finely sculptured surface similar to that of T 1 in latter).
