1. IntroductionThe genus Australomymar Girault was established with A. aurigerum as the type species (Girault, 1929) and was redescribed by Annecke and Doutt (1961) and New (1974). Narendran et al. (2003) described A. formosum from India as the first record of Australomymar from the Oriental region. Viggiani (2003) described the male genitalia from a species from Chile. Lin et al. (2007) synonymized Nesetaerus Doutt and transferred the only included species, A. gressitti (Doutt), to Australomymar. They also transferred A. incerta (Girault) from Polynemoidea Girault to Australomymar. Narendran and Anjana (2013) described a fifth species, A. vietnamicum, and provided a key to all the species.

Currently, the genus contains 6 described species: 2 from Australia, 1 from Micronesia, 1 from India, 1 from Vietnam, and the new species described below from China. Five species are keyed, based on information extracted from their original descriptions or redescriptions. The sixth species of Australomymar, A. incerta (Girault), is known only from a male, and so it is not included in the key.

2. Materials and methodsThe single specimen was dissected and mounted in Canada balsam on a slide following the method described by Noyes (1982) and modified for Mymaridae by Huber (1988).

Morphological terms follow Gibson (1997) and Huber (2012). All measurements are given in micrometers. The following abbreviations are used in the text:

YPT: Yellow pan trap.OOL: Ocular–ocellar length.POL: Postocellar length.

Mps: Multiporous plate sensilla.Fln: Funicle segment.The type specimen is deposited at Northeast Forestry

University (NEFU), Harbin, China.

Type material: Holotype ♀ (NEFU), China, Yunnan Province, Mannanxing, 11–13.I.2013. Huilin Han and Ye Chen, YPT.

Description: FEMALE. Color. Head almost black. Antenna yellowish-brown with clava brown and basal part of radicle dark brown. Mesosoma yellowish with anterior part of midlobe of mesoscutum, lateral sides of lateral lobes, sutures of sclerites, and anterior lateral part of propodeum brown, and posterior part of propodeum light yellow. Wings uniformly infumate; forewing with

submarginal vein and venation of hindwing dark brown, and forewing with a diagonal brown fold extending from apex of the stigmal vein to posterior margin of wing. Legs light brownish yellow except for a small spot on extreme base of tibia and tip of last tarsus of all legs, and about basal half of metacoxa brown to dark brown. Metasoma dark brown, except for a large spot on middle of back; second valvifer yellow and ovipositor sheaths yellowish brown.

Head (Figure 1A). In anterior view 1.35× as wide as long, in dorsal view 1.67× as wide as long. Eye without

setae. POL 1.5× OOL. Vertex with faint reticulate sculpture. Face with 2 pairs of setae between the toruli and 16–17 setae below the toruli.

Antenna (Figure 1B). Radicle about 6.11× as long as wide; scape about 1.67× as long as radicle, and about 6.13× as long as wide; pedicel longitudinally striate, about 2× as long as wide; fl1, the shortest funicular segment, about 0.6× as long as fl2, without mps; fl2, the longest funicular segment, with 1 mps; fl3 about 0.84× as long as fl2; fl4 about as long as fl5, about 0.8× as long as fl2; fl6 about 0.72× as long as fl2; fl3–6 each with 2 mps; clava about 2.79× as long as wide, and about 2.17× as long as fl6, with 7 mps.

Mesosoma (Figure 1C). Pronotum reduced to a small band, not visible dorsally. Mesoscutum about 0.76× as long as wide. Midlobe of mesoscutum with strong reticulate sculpture in anterior one-fourth and with faint reticulate sculpture in posterior three fourths, with 1 pair of adnotaular setae; lateral lobes each with 1 seta. Scutellum about 0.86× as long as mesoscutum, scutellum with faint reticulate sculpture; distance between placoid sensilla slightly greater than 2× their own diameter; frenum with strong reticulate sculpture, slightly longer than those on scutellum. Propodeum shorter than scutellum, with curved submedian carinae and 2 pairs of propodeal setae, the anterior setae longer than the posterior setae.

Wings (Figure 1D). Forewing about 3.59× as long as wide, with venation about 0.57× wing length. Longest marginal seta about 0.3× as long as the maximum width of wing. Hindwing about 20× as long as wide, longest marginal seta about 3× as long as maximum width of wing.

Legs (Figure 1E). Metatibia without conspicuous setae on outer margin.

Metasoma (Figure 1F). Ovipositor sheath about 1.75× as long as gaster.

Measurements: Body: 1220; head: 347; mesosoma: 450; metasoma: 602; ovipositor sheath: 1050. Antenna: radicle: 138; scape: 231; pedicel: 75; fl1: 75; fl2: 126; fl3: 105; fl4: 100; fl5: 100; fl6: 90; clava: 196. Forewing: 1493: 416. Hindwing: 1105: 55.

MALE. Unknown.Distribution: Only known from the type locality,

Yunnan, China.Host: Unknown.Etymology: The specific name is derived from the type

locality.Comments. Doutt (1973) illustrated the forewing of

Australian species A. incerta (Girault, 1938). It appears to lack a diagonal fold and row of setae. If the female is similar in this feature then it could be separated from the species keyed above by this feature.

The original description of formosum contains several errors. In contrast to what was stated by the authors of that species, Australomymar species have an entire frenum. All Australomymar (and probably all Mymaridae) have mps on the clava and an area of shorter and denser setae on the underside of the female clava, and there is only one pair of setae on the midlobe of the mesoscutum.
