Anteon longwangshanense Xu & He 1997g, in Yang & Wu 1997 (May): 305; type locality: Mt. Longwangshan (Zhejiang, China); He & Xu 2002: 233; syn. nov.

Description of Male. Fully winged; length 2.0 mm. Head black, except mandible testaceous; antenna black; mesosoma and metasoma black; legs testaceous, except coxae black and femora brown. Antenna filiform; antennal segments in following proportions: 5.5:2.5:4:4:4:4:3.5:3.5:3.3:5.3. Head shiny, smooth, unsculptured; vertex without two oblique keels connecting posterior ocelli to occipital carina; frontal line incomplete; POL = 1.8; OL = 1; OOL = 3; OPL = 1.5; TL = 2; greatest breadth of posterior ocelli as long as OL; occipital carina complete. Scutum shiny, with anterior fourth punctate and unsculptured among punctures; rest of surface unsculptured. Notauli incomplete, reaching about 0.5 length of scutum. Scutellum and metanotum smooth. Propodeum reticulate rugose, with strong transverse keel between dorsal and posterior surface; posterior surface reticulate rugose, with two longitudinal keels, lateral areas reticulate rugose and median area smooth. Fore wing hyaline, without dark transverse bands; distal part of stigmal vein shorter than proximal part (1.5:4.5). Paramere (Plate 21B) with distal inner pointed process. Tibial spurs 1/1/2.

Female. Unknown.

Distribution. China (Guizhou, Zhejiang).

Remarks. The new synonymy between A. cacumen and A. longwangshanense is established after a comparison of the two holotypes. This comparison proved that there are no differences. According to He & Xu (2002), the main difference between the two species concerns the median area of posterior surface of propodeum: smooh in A. cacumen and rugose in A. longwangshanense. However, the observation of the above area in the holotypes showed only light differences of not specific value. The descriptions of Anteon cacumen Xu & He and A. longwangshanense Xu & He were published simultaneously in different papers in May, 1997. According to the International Code of Zoological Nomenclature, Art. 24 a, in this case the synonymy is established by the first reviser. As first revisers, we are establishing that A. longwangshanense is a junior synonym of A. cacumen.
