( Fig. 1 View FIGURES 1, 2. 1 )

Etymology. This species is named after the dark transverse band crossing the fore wing.

Type. Holotype, female, CHINA: Guangdong, Nanling National Nature Reserve, Protection Station, 21– 25.IV.2011, yellow pan trap, Huayan Chen coll. [ SCAU].

Diagnosis. Female with head completely completely reticulate rugose, black, except mandibles testaceous; scutum and scutellum punctate, without sculpture among punctures; notauli incomplete, reaching approximately 0.6 length of scutum; fore wing with transverse dark band beneath pterostigma; posterior surface of propodeum with two complete longitudinal keels; segment 1 of protarsus about twice as long as segment 4.

Description. Female: fully winged; length 4.5 mm. Head black, except mandible testaceous; antenna testaceous, except segments 8–10 brown; mesosoma black; metasoma brown; proleg testaceous, except coxa basally black; meso- and metalegs brown, except articulations, tibiae and tarsi testaceous. Antenna clavate; antennal segments in following proportions: 17:8:11:8:8:8:8:9:9:11. Head shiny; completely reticulate rugose; face without lateral longitudinal keels around orbits directed towards antennal toruli; frontal line complete; occipital carina complete; POL = 6; OL = 4; OOL = 9; OPL = 8; TL = 6; greatest breadth of posterior ocelli shorter than POL (3.5:6). Pronotum shiny, with anterior surface sculptured by strong transverse keels and posterior surface smooth, punctate, without sculpture among punctures, shorter than scutum (8:20); pronotal tubercle reaching tegula. Scutum, scutellum and metanotum shiny, smooth, punctate, without sculpture among punctures. Notauli incomplete, reaching approximately 0.6 length of scutum. Propodeum with strong transverse keel between dorsal and posterior surface; dorsal surface reticulate rugose; posterior surface with two complete longitudinal keels, lateral areas reticulate rugose and median area rugose and medially smooth. Fore wing hyaline, with one large dark transverse band beneath pterostigma; distal part of stigmal vein much shorter than proximal part (6:15). Protarsal segments in following proportions: 13:3:3:6:16.5. Protarsal segments 2 and 3 produced into hook. Enlarged claw ( Fig. 1 View FIGURES 1, 2. 1 ) with proximal prominence bearing one long bristle. Segment 5 of protarsus ( Fig. 1 View FIGURES 1, 2. 1 ) with basal part much longer than distal part (11:5.5), with two proximal lamellae + many bristles and about 16 distal lamellae. Tibial spurs 1/1/ 2.

Male: unknown.

Hosts. Unknown.

Distribution. Oriental. China.

Remarks. This new species is similar to Anteon liui Xu, Olmi & He, 2010 , and A. tenuitarse Xu, Olmi & He, 2010 . The main difference regards the fore wing. In A. pteromaculatum it shows a large dark transverse band beneath the pterostigma; in A. liui and tenuitarse , the fore wing is totally hyaline, without dark transverse bands. The differences can be summarized as follows:

1 Fore wing with one transverse dark band beneath pterostigma.. A. pteromaculatum Xu, Olmi, Guglielmino & Chen , sp. nov.

- Fore wing hyaline, without dark transverse bands............................................................ 2

2 Distal part of segment 5 of protarsus slightly shorter than segment 4; segment 5 of protarsus with lamellae larger ( Fig. 1 View FIGURES 1, 2. 1 in Xu et al. 2010a)......................................................................... A. liui Xu, Olmi & He

- Distal part of segment 5 of protarsus slightly longer than segment 4 ( Fig. 1 View FIGURES 1, 2. 1 in Xu et al. 2010b); segment 5 of pro tarsus with lamellae smaller ( Fig. 1 View FIGURES 1, 2. 1 in Xu et al. 2010b)........................................... A. tenuitarse Xu, Olmi & He
