Description. Holotype. Male. Length 2.8 mm. LFW 2.5 mm.

Colors. Body castaneous; wings hyaline, veins castaneous.

Head. Head as long as wide, rounded. Frons polished and shining, sparsely puncticulate; frontal line absent. Vertex convex. Clypeus broad with median lobe trapezoidal, median tooth absent, apical margin crenulate, median carina short in profile. Mandible with five apical teeth, teeth with different size, upper tooth mesad, three upper teeth equally sized. Eye strongly bulging. Ocelli large, triangle with distal edges.

Mesosoma. Dorsal pronotal area very short. Notaulus absent. Parapsidal signum weakly impressed. Mesoscutellum longer than large, posterior margin convex; mesoscutum-mesoscutellar sulcus weakly arched, narrow, shallow, without fovea on side edge. Axilla oval, deep, large. Metanotal trough mostly imbricate, with few foveae, metanotal fovea drop-shaped; median region narrow, large, with posterior margin straight. Metapectal-propodeal complex long, posterior margin convex; metapostnotal median carina absent, metapostnotum almost entirely polished. Metapectal-propodeal complex polished. Paraspicular sulcus polished; lateral carina of metapectal-propodeal carina absent; lateral surface of propodeum polished, inferior region imbricate. Propodeal declivity polished-imbricate.

Metasoma. Petiole short. Hypopygium with plate long, posterior margin almost straight, flap absent. Genitalia: paramere straight. Basivolsella apical inner margin smooth. Basiparamere with apical dorsal projection small, apex convex. Cuspis with apical margin with two apical calli, dorsal larger than other, dorsal end very short. Aedeagus with two apical lobes, ventral lobe short; dorsal lobe short; subapical membrane short; aedeagal dorsal cover narrow.

Female. Unknown.

Material examined. Holotype ♂, BRAZIL, Bahia, Itajuípe, Faz. Trindade, 27.XI.2002, arm. Malaise ( CE- PLAC)  . Paratypes: BRAZIL: 1 ♂, Bahia, Itajuípe, Faz. Trindade, 27.XI.2002, arm. Malaise ( CEPLAC); ES  : 1 ♂, Pancas, Faz. Juliberto Stur , 19°13’10.5”S, 40°46’28.8”O, 24–31.i.2003, Armadilha Malaise, T3  , M. T. Tavares, C.O. Azevedo e eq. col. ( UFES Nº 11272)  ; 2 ♂, Réserve Linhares, Brésil, Malaise , 15–30 novemb 2000, Bethylidae  ( MNHN)  .

Comments. This species is similar to A. laevigata  because the head is rounded; the clypeus is trapezoidal; the mandible has five teeth; the pronotum is very short; the mesoscutellum is long; the metapectal-propodeal complex is long with the posterior margin convex; the petiole is long; the hypopygium has the plate long; the genitalia has the basiparamere clearly divided and the aedeagus narrow with the ventral lobe very short. In the new species, however, the apical margin of the clypeus is crenulate, the notaulus is absent, the mesoscutum-mesoscutellar suture is weakly arched and narrow, whereas A. laevigata  presents the clypeus with a smooth apical margin; the notaulus present and the mesoscutum-mesoscutellar suture strongly arched and wide.

Distribution. Neotropical ( Brazil).
