brasiliensis species­group

Description.— Male. Body length 4.94 mm; LFW 3.0 mm. Color: head and mesosoma black, except pronotum dark castaneous, metasoma rufous castaneous, mandible and antenna castaneous, palpi, tegula and legs yellowish castaneous, wings hyaline, veins castaneous.

Head ( Fig. 14 ): mandibles with five large teeth ( Fig. 15 ). Clypeus with truncate median lobe with rounded corners, median carina very high and angled in profile. First four antennal segments in a ratio of 40:9:28:30, segment III 2.8 X as long as thick, segment XI 3.57 X as long as thick. Eyes glabrous. Frons polished, with conspicuous punctures, absent near the toruli and eyes. WH 0.9 X LH; WF 0.6 X WH, WF 1.12 X HE; OOL 1.7 X WOT; frontal angle of ocellar triangle acute; distance from the posterior ocelli to vertex crest 1.5 X DAO. Vertex barely convex, corners rounded, occipital carina visible in dorsal view. VOL 0.66 X HE.

Mesosoma ( Fig. 14 ): thorax polished. Pronotal disc with anterior carina. Notauli well impressed, incomplete anteriorly. Parapsidal furrows incomplete anteriorly. Propodeal disc 1.33X as wide as long, basal triangle and longitudinal ridges, otherwise polished, declivity without median carina.

Metasoma: petiolate, petiole very short 0.1 X as long as the tergite I. Genitalia ( Fig. 16 ): paramere short, 0.58 X as long as the basiparamere, apical margin strongly concave, inner portion rounded and somewhat shorter than outer corner, the latter angulate; volsella with the ventral ramus of digitus moderately wide and high, 0.5 X as long as the paramere, apex rounded, inner margin somewhat angulate and the outer straight; aedeagus with two pairs of apical lobes, the apex of lateral pair directed downward, with the outer corner rounded and the inner angled, base of the lobes with inner margin strongly constricted, the median pair small, thin and slightly directed upward.

Material examined.— HOLOTYPE: male, BRAZIL, Pará, Tucuruí, Rio Tocantins, v.1986, Interception trap, N. Degallier col. ( MPEG). PARATYPES: BRAZIL, Pará, 3 males, Tucuruí, Rio Tocantins, 08–20.IV.1986, Interception trap, N. Degallier col. ( MPEG).

Remarks.—When Evans (1963) revised the type of A. brasiliensis (Kieffer, 1910) , he included in his study the description of the genitalia of a specimen from Santarém ( Brazil, Pará). It does not correspond to the genitalia of the type. We did not see the specimen from Santarém, but according to the illustration in Evans (1963, fig. 111), it fits perfectly in A. lapsa .

Etymology.—The name refers to the genitalia of this species having been described originally as that of A. brasiliensis .
