Description. Holotype. Female. Body length 2.3 mm, fore wing length 2.4 mm.
Head. Transverse in dorsal view, nearly 2.1× as wide as long, 1.2× wider than mesoscutum. Vertex between eye and posterior ocellus highly shiny, polished, and impunctate. Temple shiny with superficial discrete punctures, rather short, strongly constricted. Face 0.8× as high as wide, highly shiny, polished, and impunctate, sparsely pubescent, inner margin of subparallel-sided. Ocelli not large, posterior tangent to anterior ocellus just touching posterior ocelli, distance between fore and hind ocellus as long as diameter of hind ocellus, POL:OD:OOL=4.5:2.0:3.5. Antenna indistinctly longer than body length, not shrunken apically, closely articulated, penultimate flagellomere 1.3× longer than wide.
Mesosoma. Length:width:height = 40.0:23.5:37.0. Disc of mesonotum shiny, with large, dense punctures, interspaces smaller than diameter of puncture and rugulose at posterior part of notaulic courses (without longitudinal striations), hind margin highly shiny and polished. Scutellar sulcus slightly curved, relatively wide with sparse carinae inside. Scutellum shiny and polished, median length indistinctly longer than basal width. Lateral polished field of scutellum reaching hardly half length of scutellum. Propodeum shiny, uneven and weakly rugulose anteriolaterally, elsewhere shiny and smooth, areolation strongly, well defined, V-shaped apically and closed basally, costulae strongly, well defined. Mesopleuron highly shiny, anterior part with discrete, small punctures, rather weakly strigulate on sternaulus.
Legs. Hind femur 3.2× longer than wide. Hind coxa shiny and smooth, except for some shallow punctures above (basally). Spines on outer side of third tibia of two different kinds, scattered. Inner spurs of hind tibia 2/5 length of hind basitarsus, outer spur 1/3. Basitarsus of hind leg weakly shorter than tarsomeres 2–4 combined (16.0:17.5), claws of normal size.
Wings. Pterostigma 2.3× as long as its widest part. Vein 1-R1 1.4× longer than pterostigma, 6.2× as long as its distance from apex of marginal cell. Vein r arising from middle of pterostigma, strongly oblique to the latter, 0.6× as long as width of pterostigma, r as long as 2-SR, distinctly angled at junction, 2-M half length of 2-SR and almost as long as 1-SR, 2-SR+M slightly longer than 1-SR, cu-a slightly longer than 2-SR+M. First discal cell of fore wing nearly 1.3× wider than high. Second submarginal cell of hind wing one-and-a-third times wider than high. Vein cu-a slightly curved. Hind wing narrow, length of 1-M equal with distance between its distal extremity and apex of vannal lobe, and vannal lobe beyond its widest straight and without setae.
Metasoma. Nearly 1.3× longer than mesosoma (50.0:40.0). T1 subparallel-sided, 2.1× longer than hind width, concave at basal third, turned-over part 1.4× longer than wide, slightly shiny and rugose punctate, longitudinal trough broad, shallow, apical tubercle shiny and polished. T2 shiny and weakly rough, but impunctate, 3.6 × wider than long in the middle, nearly straight apically. T3 1.9× longer than T2. Tergites posterior to T2 shiny, smooth, sparsely pubescent. Hypopygium broad, distinctly longer than apex of metasoma. Ovipositor sheath 1.1× longer than length of hind tibia, thin. Ovipositor relatively thin, weakly curved, without apical attenuation.
Colour. Black, except tergites posterior to T1 brown. Tegula honey yellow. Palpi and spurs pale yellowish. Antenna yellowish brown and ovipositor sheath brown. Labrum and mandible reddish brown. Legs yellow, except most part of hind coxa, extreme apex of hind femur, apical 3/5 of hind tibia, and hind tarsus reddish brown. Wing membrane hyaline to indistinctly brownish, C+SC+R, 1-R1, pterostigma, r, 2-SR and 2-M yellowish brown, the rest more or less pale yellowish brown.
Variation. Body length 1.9–2.4 mm, fore wing length 2.0– 2.5 mm. Apex of hind femur somewhat yellowish brown to apical half of hind femur blackish brown.
Male. Unknown.
Material examined. Holotype: 1♀, Changsha, Hunan, 1980, Tong Xinwang, No. 20044877. Paratypes: 1♀, Qingliu , Fujian, 1986.VI.20, Qi Shicheng, No. 865204 ; 1♀, Xiamen , Fujian, 1988.VII.26–27, Ma Yun, No. 883817 ; 1♀, Mt.

VIII.13, Yan Chengjin, No. 201101055 ; 5♀♀, Changsha , Hunan, 1980, Tong Xinwang, Nos. 20044851, 20044834, 20044851, 20044830, 20044887 ; 1♀, Gaozhonglindao , Taiwan, 2011.VI.8, Tang Pu, No. 201105453 .
Distribution. China (Fujian, Guangxi, Hunan, Taiwan).
Etymology. The specific name “ brevitempus ” derives from the Latin “brevis” and “tempus”, referring to the temple rather short.
Remarks. This species is similar to A. saravu , but differs in the following: posterior end of notaulic courses with somewhat rugulose punctures (indicated by a zone of shiny striate-punctation in latter); legs mostly yellow (obscure brownish throughout in latter); and wing membrane hyaline to indistinctly brownish (markedly brownish in latter).
