Genus Globimesosoma Xiao et Huang, 2001 View in CoL
Type species: Globimesosoma yaoarum Xiao et Huang, 2001 , by original designation.
Characteristics of the genus. Head and mesosoma black or dark metallic green with diffuse coppery lustre, metasoma dark brown with green and blue metallic lustre ( Figs 1, 3, 10, 13); plate of fore wing hyaline. Head in dorsal view reticulate, clypeus radially striate; mesosoma and propodeum distinctly reticulate; metasoma weakly alutaceous and shiny. Head in dorsal view 2.10–2.30 times as broad as long; scrobes absent; occiput without carina; lower margin of clypeus with two teeth ( Figs 2, 4, 11). Antennal formula 11353 ( Figs 7, 14), antenna inserted above level of lower margins of eyes ( Figs 4, 11); flagellum almost filiform; all anelli transverse, F1–F5 longer than broad, F1 with two–three rows of dense sensilla ( Figs 7, 14), clava symmetric.Mandibular formula 4:4. Mesosoma usually moderately arched dorsally; pronotum with smooth and shiny carina; notauli incomplete ( Figs 8, 16); scutellum with weak and shallow frenal line. Propodeum without median carina and plicae; nucha reduced; spiracles situated nearer to metanotum ( Figs 8, 16). Petiole transverse. Fore wing with speculum; basal cell bare or with four hairs; marginal vein long, 2.70–3.80 times as long as stigmal vein ( Figs 6, 15). Metacoxa distinctly long and in dorsal view bare ( Figs 1, 10); metatibia with one spur. Metasoma lanceolate, longer than combined length of head and mesosoma; cerci with setae subequal in length.
Comparative diagnosis. The genus is very similar to Holcaeus Thomson, 1878 in the following characters: antenna with three anelli; pronotum narrower than mesoscutum; pronotal collar with smooth carina; nucha of propodeum reduced. Globimesosoma distinctly differs from Holcaeus in the occiput without carina ( vs with carina); lower margin of clypeus with two teeth ( vs lower margin of clypeus broadly truncate); mandibular formula 4:4 ( vs 3:3).
