Taxonomic remark – The two specimens (male and female) described by SZÉPLIGETI (1902: 39–40) under the names Bracon chinensis (♂) and Bracon puellaris (♀), respectively, are conspecific, its valid name is Amyosoma chinense (SZÉPLIGETI). VAN ACHTERBERG & POLASZEK (1996) assigned the species chinense in this genus.
Designation of the male holotype of Bracon chinensis – (First label, handwriting) “ China ”; (second label) “ B. chinensis ” (Szépligeti’s handwriting) “det. Szépligeti” (printed); third label is the holotype card, fourth label is with the inventory number “1279”, fifth label is with the actual name Amyosoma chinense Szépl. ♂ (det. J. Papp 2009), labels 3–5 attached by me. – Holotype is in fairly poor condition: (1) micropinned by mesosoma; (2) right flagellum apically deficient (i.e. with 19 flagellomeres or 21 antennomeres), left flagellum mising; (3) wings slightly damaged; (4) tarsomeres 2–5 of left hind leg missing.
Designation of the female holotype of Bracon puellaris – (First label, my handwriting) “ Indonesia / Borneo”; (second label) “ B. puellaris ” (Szépligeti’s handwriting) “det. Szépligeti” (printed); third label is the holotype card, fourth label is with the inventory number “1280”, fifth label is with the actual name Amyosoma chinense Szépl. ♀ (det. J. Papp 2009), labels 3–5 attached by me. – Holotype is in good condition: (1) micropinned by mesosoma; (2) right flagellum apically deficient (i.e. with 22 flagellomeres or 24 antennomeres).
Designation of the female lectotype of Amyosoma chilonis – (First label, printed) “Taiholu / Formosa ”; (second label, printed) “ex Chilo / simplex”; (third label) “July” (printed) “1911” (handwriting); (fourth label) “T S Shiraki / coll.”; (fifth red label) “Type / No.” (printed) “15329” (handwriting) / “ U.S. N.M.” (printed); sixth label is the name label by (?)Viereck’s handwriting, seventh label is the lectotype card and eighth label is with the actual name Amyosoma chinense (Szépl.) (labels 7–8 attached by me). – Lectotype is in good condition: (1) glued on a pointed card by the left mesopleuron; (2) both flagelli missing; (3) left fore and hind legs glued on the card with the wasp itself; (4) intersternite (of metasoma) and middle pair of tarsi somewhat white mouldy.

A concise redescription of Amyosoma chinense (SZÉPLIGETI) was presented by VAN ACHTERBERG & POLASZEK (1996: 22), subsequently complementary features are added to it based mainly on the female holotype of A. puellaris (SZÉPLIGETI).
Female: Body 4–5 mm long. Antenna about as long as body and with 32–39 antennomeres. Flagellomeres 1.3 to 1.8 times as long as broad (cf. Fig. 72 in VAN ACHTERBERG & POLASZEK 1996: 86). Head in dorsal view transverse, 1.6–1.8 times as broad as long, eye almost twice longer than temple, temple rounded (Fig. 30) eye in lateral view 1.5 times wider than temple (Fig. 31). Oral opening: its horizontal diameter (1.5–)1.6–1.7 times longer than shortest distance between opening and eye. Head polished, face finely granulose.
Mesosoma in lateral view 1.6–1.7 times as long as high, polished. Notaulix faintly distinct. Hind femur 2.9–3 times as long as broad with short and adpressed hairs (Fig. 32). Claw and its basal lobe as in Fig. 33.
Fore wing as long as body. Pterostigma (Fig. 34) 2.6–3.3 times as long as wide and issuing r more or less proximally from its middle, r shorter than (rarely as long as) width of pterostigma. Second submarginal cell long, 1.6–1.75 times longer than 2–SR, SR1 1.3–1.4 times as long as 3–SR and rather approaching tip of wing. First discal cell narrow, 1–M 1.4–1.5 times as long as m–cu, 1–SR–M straight and 1.85–1.9 times length of 1–M (Fig. 35). – Hind wing: 1r–m straight to weakly bent (Fig. 36).
First tergite (Fig. 37) long, 2.2–2.6 times as long as broad behind, its margin laterally from scutum very narrow, together with further tergites polished. Tergites 2 and 3 transverse, third tergite either as long as or longer than second tergite (Fig. 37). Hypopygium pointed, ovipositor sheath shorter than to as long as hind tibia + basitarsus combined.
Corporal colour as in VAN ACHTERBERG & POLASZEK (l.c.) Melanic form: head and mesosoma rusty brown (1 ♀); albanic form: head and mesosoma brownish yellow or ochre (2 ♀♀).
Male: Similar to the female. Body 4–4.5(–5) mm long. Antenna as long as body and with 37–38 antennomeres. Melanic form: metasoma black (cf. VIERECK 1913: 640).
Distribution – Oriental and East Palaearctic Regions. Introduced into Afrotropics and Pacifics.
Taxonomic position – Considering VAN ACHTERBERG & POLASZEK’ s key (1996: 21) for the Amyosoma species the nearest two species to M. (A.) chinense are M. (A.) leuzerae ROHWER (Indonesia: Java) and M. (A.) yanoi (WATANABE) (Japan). The three species are very similar to each other, the differences among them restricted to minute lengths of the ovipositor sheath and somewhat variable colour pattern of the body.
