( Figs 48–51 View FIGURES 48 – 51 , 81 View FIGURES 78 – 81 )

Diagnosis. Whole yellowish species with brown antenna; head shining coriaceous, occipital carina complete, dorsally receding, ventrally not meeting hypostomal carina; clypeus weakly bulging; fore wing vein r-m present, second submarginal cell very short, barely square; hind coxa rugose dorsally; hind wing vein RS straight well pigmented; metasomal tergite 1 relatively short; second metasomal tergite rugose-striate interspaced with areolate sculpturing; third terginte weakly striate with medial carina on basal half; first two flagellomeres fused, division between segments faintly indicated.

Description of holotype. ♀, body length 3.4 mm, fore wing length 2.6 mm, antenna 5.7 mm.

Head. Antennal segments 46, first flagellomere extremely long, composed by first three segments fused (the division line of second and third segment is clear but they are not articulated), length of first and second flagellomeres 8.7 and 3.0 times their width, respectively; length of maxillary palpi 0.8 times height of head; length of eye in dorsal view 3.5 times temple; head sculpturing shining granular-coriaceous; occipital carina dorsally complete and strongly receding, not reaching hypostomal carina ventrally; POL:OD:OOL = 3:3.5:5; face with weak median crest; clypeus weakly protruding in lateral view; oral opening 0.28 times width of face; malar space 1.4 times basal width of mandibles and 0.33 times eye height in frontal view; inner margin of compound eyes weakly indented.

Mesosoma. Length of mesosoma 1.5 times its height; sculpturing mostly shining granular; pronotum smooth and polished, weakly shining granular ventrally; precoxal sulcus extending over most of mesopleuron, shallow and crenulate anteriorly; antescutal depression indistinct, pronotal collar polished with a mid longitudinal carina; mesoscutum with v shaped carina present posteriorly; notauli shallow and very weakly crenualte anteriorly, meeting in triangular area with short mid-longitudinal carina posteriorly; scutellar sulcus smooth and polished with one median plus one pair of lateral longitudinal carina, carina well defined; propodeum mostly areolate-rugose, granulate anteriorly, longitudinal carina nearly complete; ventral midline of mesopleuron set within deep and wide, crenulate sulcus.

Wings. Fore wing: vein r-m present, second submarginal cell barely square, vein 2M slightly shorter than vein 3-SR; r:3-SR:SR1:2-SR:2-SR+M = 7:10:45:10:9; vein 1-SR+M virtually straight; vein 1-M evenly curved; 1- CU1:2-CU1:cu-a = 11.5:19:4. Hind wing: vein cu-a short and reclivous; M+CU:1-M:1r-m = 2:5:1; vein RS weakly bent down medially; vein m-cu absent.

Legs. Tarsal claws simple, not pectinate, its apical tooth curved upward; hind coxa granulate, transversely costate dorsally; femur, tibia and basitarsus of hind leg 5.1, 8.0 and 7.2 times their width, respectively; length of inner hind tibial spurs 0.34 times hind basitarsus; hind tarsi 1.2 times as long as hind tibia.

Metasoma. Petiole relatively short and narrowing basally, about 2 times wider apically than basally, length of first tergite 1.25 times its apical width; mid-longitudinal carina distinct throughout first and second terga; first tergite rugose; second tergite rugose-costate with finely areolate background, smooth basal triangular very short; third tergite striate on basal half; remaining tergites smooth and polished; length of second tergite 1.5 times median length of third tergite; ovipositor sheaths acute apically, about as long as hind tarsomere II and 0.1 times as long as fore wing, with distinct thin and acute projection; dorsal carina of petiole forming a triangular area basally; base of petiole without lateral flanges.

Color. Entire body honey yellow; flagellum with first 25 segments dark brown, apical 19 flagellomeres white, scapus honey yellow dorsally; wings hyaline, veins and stigma brown, apex of stigma light pale yellow.

Variation. Paratype body length 3.2 mm, otherwise virtually identical to holotype.

Male. Unknown

Distribution. Known from Porto Velho, Rondônia state, BRAZIL.

Type material. Type-locality: BRAZIL, Rondônia state, Porto Vellho, Reserva Extrativista do Lago do Cuniã, S 8°19’27” W 63°29’44”, Malaise trap. Type-specimen: HOLOTYPE, ♀ ( DCBU #10942), point mouted. Top label: “Porto Velho, RO, Brasil / Reserva do Cuniã / S 8°19’27” W 63°29’44” / Armadilha Malaise Pto. 1 / 26.VI.2011 / A.S. Soares col.”; bottom label: “10942”. PARATYPE, 1♀ ( DCBU #19879), same as holotype, Parque Natural Municipal, S 8º41’12” W 63º52’10”, D. Santana col.

Discussion. This new species is similar to A. achterbergi sp. nov. and A. paradoxus sp. nov. The head does not have the elevated frons as in A. paradoxus sp. nov., and is different from the other two species where the occipital carina is evenly rounded (the occiptal carina clearly recedes dorsally in A. soaresi sp. nov.). It also differs from the two closest species in the smooth and polished scutellar sulcus, with three complete and well-defined carinae, one median plus one pair of lateral carinae, as compared with only median carina present in A. achterbergi sp. nov. and only the lateral pair of carina present and not well-defined in A. paradoxus sp. nov. The body color is almost identical to A. paradoxus sp. nov., except for the narrow dark brown bands at the joints between hind femur and trochantellus and the extreme base of hind tibia present in A. paradoxus sp. nov. (absent in A. soaresi sp. nov.). Another useful and unique diagnostic character for this species is the extremely short second submarginal cell on fore wing, where veins 2-SR and 3-SR have nearly the same length, and vein 2M is slightly shorter than vein 3-SR.

Etymology. This species is named after the collector of the type specimen, our dear friend Airton Santo Soares.
