Type material examined. Holotype male (Fig. 51) of P. draperi [QMBA] on slide (Fig. 49) labeled: 1. “ Polynema draperi Girault Ƌ. Type. 1069 Cooktown, NQ. 3616”; 2. “ TYPE Hy/1069 A. A. Girault”; 3. “ Abbella [crossed out] Tumidiclava ciliata GRLT. 5♀ ’s, Sweeping grass. February 27, 1912 ”; 4. “3616”; 5. [blue] “ PARATYPES T. 8774 E. C. D. 1983”. The holotype is in good condition but with one hind wing missing. It is mounted dorsoventrally under the same, complete coverslip with 5 female paratypes of Tumidiclava ciliata Girault (Trichogrammatidae) . Paratype male of P. draperi [QMBA] on slide (Fig. 50) labeled: 1. “3392 Lathromeroidea nigrella Girault ♀ 3392 Ƌ Upolynema draperi Windows of dwellings, Cooktown, NQ. 31 Jany. 1912. AAG. 7951”; 2. “Hy/1069. Ƌ”; 3. “ Queensland Museum. Lathromeroidea TYPE Hy/ 795 ♀ ”. On the first label A.A. Girault crossed out the “ -is ” ending of the previous generic name [ Lathromeris] and replaced it with “- oidea ”, and crossed out the previous specific name and also “Grlt”. The paratype specimen is in poor condition, with the head (with both antennae attached) and also one fore wing and one hind wing detached from the body. It is mounted laterally under the same, complete coverslip with the holotype of Lathromeroidea nigrella Girault (Trichogrammatidae), a male Lymaenon sp. ( Mymaridae), and one unidentified trichogrammatid.

Material examined. AUSTRALIA. QUEENSLAND: Gordonvale [as Nelson], 12.viii.1913, A.P. Dodd, forest [1♀, QMBA] (paratype of P. frater Girault). Mount Cook National Park, 10–12.v.1981, I.D. Naumann [1Ƌ, ANIC] .

Description. FEMALE (previously unknown, paratype of P. frater). Head, flagellum, mesosoma, and gaster brown; scape, pedicel, petiole, and legs light brown. Antenna (Fig. 45) with scape smooth, 3.1× as long as wide excluding radicle; pedicel smooth, 1.7× as long as wide, much longer than F1; F2 the longest funicular, F3 about as long as F6 and longer than F4 or F5; F4 the shortest funicular, length to width ratios of funiculars: F1—2.0, F2—4.5; F3—2.7; F4—1.6; F5—1.8; F6—1.9, F6 possibly with 1 mps; clava 2.6× as long as wide, almost as long as combined length of 4 preceding flagellomeres, with 7 mps. Mesosoma (Fig. 46) apparently smooth; mesoscutum a little longer than scutellum; scutellum with campaniform sensilla closer to anterior margin than to posterior margin and separated from each other by about the same distance as each sensillum from lateral margin of scutellum, and with frenal row of foveae; propodeum (Fig. 48) with an incomplete median carina extending from posterior margin for less than half length of propodeum. Fore wing (Fig. 47) possibly about 5× as long as wide (not possible to measure accurately), with disc hyaline, densely setose beyond venation. Gaster (Fig. 46) a little longer than mesosoma. Petiole with anterolateral “wings” (Fig. 48). Ovipositor apparently about 0.8× length of gaster, possibly not or just barely exserted beyond its apex (gaster apex not clearly visible).

Measurements (µm). Body (without head): 769. Mesosoma: 327; petiole: 97; gaster: 364. Scape (excluding radicle): 94; pedicel: 49; F1: 27; F2: 57; F3: 35; F4: 24; F5: 30; F6: 36; clava: 127.

Redescription. MALE (holotype of P. draperi except when indicated otherwise). Head, flagellum, mesosoma, and gaster brown to dark brown; scape, pedicel, petiole, and legs light brown. Antenna (Figs 52, 55) with scape and pedicel smooth, flagellomeres much longer than wide and longer than scape, all subequal in length and width, each with several mps. Mesosoma (Fig. 53) much longer than gaster; pronotum divided mediolongitudinally; mesoscutum and scutellum with fine mesh-like sculpture; mesoscutum a little longer than scutellum; scutellum with campaniform sensilla closer to anterior margin than to posterior margin and separated by about the same distance as each sensillum from lateral margin of scutellum (Fig. 53 and as in Fig. 56), an additional campaniform placoid sensillum in the middle (Fig. 53), and with frenal row of foveae (Fig. 53 and as in Fig. 56); propodeum with an incomplete median carina extending from posterior margin for almost half length. Fore wing (Figs 54, 57) 5.6× as long as wide; marginal vein short, with 1 dorsal macrochaeta; disc mostly almost hyaline (slightly infumate along anterior margin), densely setose beyond venation; longest marginal seta 1.3× greatest width of wing. Hind wing (paratype) about 29× as long as wide, with disc hyaline; longest marginal seta 5.6× greatest width of disc. Petiole with anterolateral “wings” (Fig. 54). Genitalia (as in Fig. 58) typical for species of P. ( Polynema) (Triapitsyn & Fidalgo 2006), 109 µm long (non-type specimen); digitus with two small denticles.

Measurements of the holotype (µm). Body: 640; mesosoma: 272; petiole: 58; gaster: 197. Scape (excluding radicle): 64; pedicel: 45; F1: 91; F2: 90; F3: 91; F4: 90; F5: 85; F6: 85; F7: 85; F8: 80; F9: 82; F10: 85; F11: 88. Fore wing: 726:129; longest marginal seta: 167.

Diagnosis. This species is similar to P. editha but males of the latter have the basal half of the fore wing relatively wider and the genitalia (Fig. 72) are relatively more elongate than in P. draperi (Fig. 58). Females of P. draperi have F2 of the antenna relatively shorter (Fig. 45) than females of P. editha (Figs 60, 65), as indicated in the key with their length to width ratios.

Distribution. Australia (northern and northeastern Queensland).

Remarks. Another male paratype of P. draperi (from Thursday Island, Queensland, Australia) is deposited in USNM (Dahms 1983); it was not examined.
