Anteon holzschuhi Olmi, Xu, Guglielmino & Speranza sp. n.

Diagnosis.

Male with antenna filiform; face partly reticulate rugose and partly sculptured by deep punctures similar to areolae (Fig. 1B); OOL about 3.3 times as long as OL (Fig. 1A); notauli reaching about 0.8 length of scutum (Fig. 1A); posterior surface of propodeum with two complete longitudinal keels and median area unsculptured; distal part of stigmal vein much shorter than proximal part; paramere about as long as penis, without papillae on inner side, without distal inner process (Fig. 2); distivolsella not provided with two lateral processes (Fig. 2).

Description.

Male. Fully winged (Fig. 1A). Length 4.5 mm. Head black, except mandible testaceous. Antenna brown-testaceous, except proximal half of segment 1 testaceous. Mesosoma black. Metasoma brown. Legs testaceous, except metacoxa basally brown. Antenna filiform. Antennal segments in following proportions: 17:10:16:15:14:14:14:14:13 (segment 10 missing in holotype). Head (Fig. 1A, B) shiny. Face partly rugose and partly strongly punctate, with deep punctures similar to areolae, unsculptured among punctures. Vertex and temple with deep punctures similar to areolae, unsculptured among punctures. Frontal line complete. Vertex with POL = 7; OL = 3; OOL = 10; OPL = 7; TL = 7; greatest breadth of posterior ocelli shorter than OPL (5:7). Occipital carina complete. Pronotum short and strongly punctate. Scutum and scutellum shiny, punctate, unsculptured among punctures. Notauli incomplete, reaching approximately 0.8 x length of scutum (Fig. 1A). Metanotum shiny, unsculptured. Propodeum with strong transverse keel between dorsal and posterior surface. Dorsal surface of propodeum reticulate rugose. Posterior surface of propodeum with two complete longitudinal keels, median area unsculptured, and lateral areas rugose. Forewing hyaline, without dark transverse bands. Distal part of stigmal vein much shorter than proximal part (7:16). Paramere (Fig. 2) about as long as penis, without distal inner pointed process and papillae, with long and broad dorsal proximal membranous process. Tibial spurs 1/1/2.

Etymology.

The species is named after the collector, Mr Carolus Holzschuh (Villach, Austria).

Remarks.

The new species is similar to Anteon semipolitum Olmi, 2008, by having the antenna filiform, notauli reaching about 0.8 × length of scutum (Fig. 1A), posterior surface of the propodeum with two complete longitudinal keels and unsculptured median area, distal part of stigmal vein much shorter than proximal part, paramere about as long as penis, without papillae on inner side, without distal inner process (Fig. 2) and distivolsella not provided with two lateral processes (Fig. 2). The main difference between the two species is in the facial sculpture (face partly reticulate rugose and partly sculptured by deep punctures similar to areolae in Anteon holzschuhi (Fig. 1B); face punctate and unsculptured among punctures in Anteon semipolitum ). In addition, OOL is about three times as long as OL in Anteon holzschuhi , less than twice in Anteon semipolitum . In the key to the males of Oriental Anteon published by Xu et al. (2013), the new species can be included by replacing couplet 43 as follows:
