Figure 1

TYPE MATERIAL — Female holotype, Papua New Guinea. Madang Province, Mt. Wilhelm, -5.721022, 145.2703, 1200 m, 26-27.X.2012, Malaise trap, MW 1200B-02, P1795-11299, Philip, Alois, Novotny & Leponce leg. ( MNHN). Paratype: same locality label as holotype, 1 female ( MNHN).

DISTRIBUTION — Papua New Guinea.

DESCRIPTION — FEMALE: Fully winged; length 3.7 mm. Head black, except mandible testaceous; antenna testaceous,

except segments 6-10 brown; mesosoma black; metasoma brown; foreleg whitish, except tarsus testaceous; mid and hind legs whitish, except tibiae and tarsi testaceous. Paratype with antenna brown, except segments 1-2 testaceous; legs brown, except part of coxae, trochanters and tarsi testaceous. Antenna clavate; antennal segments in following proportions: 16:7:12:9:8:9:8:8:8:11. Head dull, completely reticulate rugose; frontal line complete; face without lateral keels around orbits and directed towards antennal toruli; occipital carina complete; POL = 7; OL = 4; OOL = 5; OPL = 6; TL = 4; greatest breadth of posterior ocellus about as long as OOL. Pronotum dull, reticulate rugose, except for transverse stripe near posterior margin unsculptured; posterior surface shorter than scutum (10:17); pronotal tubercle reaching tegula. Scutum dull, with median region anteriorly sculptured by large punctures, posteriorly reticulate rugose; lateral regions

sculptured by oblique curvilinear keels. Notauli incomplete, reaching approximately 0.5× length of scutum. Scutellum and metanotum punctate, unsculptured among punctures. Propodeum reticulate rugose, with strong transverse keel between dorsal and posterior surface; posterior surface with two longitudinal keels and lateral areas rugose; median area shiny,

mostly unsculptured, with areolae along lateral margins. Forewing hyaline, without dark transverse bands; distal part of

stigmal vein much shorter than proximal part (3:13). Protarsal segments in following proportions: 7:3:6:11:27. Enlarged

claw (Figure 1) with proximal prominence bearing one long bristle. Segment 5 of protarsus (Figure 1) with basal part shorter than distal part, with two rows of approximately 34 lamellae without interruption to distal apex. Tibial spurs 1/1/2.

MALE: Unknown.

ETYMOLOGY — The species is named after Dr. Maurice Leponce.

HOSTS — Unknown.

REMARKS — A. leponcei is similar to A. corruptum Olmi, 1984 , and A. miles Olmi, 1984, but with different notauli and POL/OOL ratio (see key below). The new species can be included in the key to the females of the Australasian Anteon published by Olmi (1984) by replacing couplets 15 and 16 as follows:

15 Scutum completely or mostly reticulate rugose or partly sculptured by irregular keels ............................... 15’ – Scutum punctate or very weakly granulated, not reticulate rugose ..................................................................... 17

15’ Head with POL longer than OOL; notauli reaching about 0.5 × length of scutum ........... A. leponcei n. sp. – Head with POL shorter than OOL; notauli absent, or reaching about 0.75 × length of scutum .................. 16

16 Scutellum smooth; notauli absent, or faintly and shortly visible near anterior margin of scutum .................. ................................................................................................................................................................... A. corruptum Olmi – Scutellum partly reticulate rugose; notauli reaching approximately 0.75 × length of scutum ........................... ............................................................................................................................................................................. A. miles Olmi
