Female. Body length 2.5–3.5 mm; fore wing length 2.5–3.4 mm

Head. Smooth and polished, with scattered setae; 1.30–1.35x wider than mesoscutum. Face 1.6–1.9x broader than long, mostly smooth and polished but very finely rugose just above clypeus. Clypeus 2.2–2.8x broader than long. Malar space about 0.42–0.48x eye height in frontal view. In lateral view, eyes 1.2–1.7x longer than temple. Maximum width of lateral ocellus about 0.37–0.41x ocell-ocular distance. Antenna 1.2–1.3x longer than fore wing, 30–38 segmented; first flagellomere 3– 4x longer than wide.

Mesosoma  . About 2x longer than high. Mesonotum 1.4–1.6x longer than width of mesoscutum. Pronotum dorsally gently rugose and virtually flat posteriorly, with distinct mid-longitudinal carina anteriorly; about 1.1x longer than vertex, the posterior region 3x longer than anterior region; laterally mostly smooth and polished, pronotal groove with few rugosities anteriorly and posteriorly, scattered setae ventrally and along posterior margin. Mesonotum smooth and polished; setae scattered over mesonotum, but moderately denser anteriorly at mesoscutum and posteriorly at scutellum; notauli present on anterior 0.32–0.44 of the mesoscutum, crenulate; mid pit long and narrow, 0.5–0.7x the length of mesoscutum; scutellum 1.1–1.4x longer than wide, smooth and polished; scutellar sulcus 0.35–0.39x longer than wide, with one median carina; mesoscutellar trough mostly costate, rugose distally. Metanotum without median carina, laterally costate with few short and sparse setae. Mesopleuron bare on central portion, setae concentrated on anterior corner and ventrally; sternaulus short and crenulated; anterior corner of mesopleuron weakly rugose. Epicnemial carina present ventrally, incomplete. Metapleuron rugose, with long and scattered setae. Propodeum mostly rugose and not polished anteriorly with narrow basal sulcus along margin with metanotum; areola roughly pentagonal, with distinct cross-bridge and two pairs of transverse lateral carinae ( Fig. 18View FIGURES 14 – 25); median carina relatively long, posteriorly irregular. Hind coxa 1.6–1.8x longer than wide, 0.6– 07x as long as metasomal TI. Hind basitarsus about 0.38–0.41x as long as hind tibia. Hind tarsal claws without basal lobe.

Wings. Fore wing. Stigma narrow. 5– 6x longer than broad; vein r arising from middle of stigma. Vein r 0.48– 0.59x longer than vein 3 RSa  . Vein 2RS distinctly sinuate, 0.76–0.96x longer than 3RSa. Vein 3 RSa 0.5–0.6 x 3 RSb and 1.9–2.2x as long as vein r-m. Vein 1 Cub 1.4–1.6x vein 1CUa. Vein (RS+M)b relatively long, not pigmented. Vein 1-1AC 0.10–0.16x longer than vein 2-1 A. Hind wing. Vein M +CU 1.4–1.8x longer than 1M. Vein cu-a about 0.4–0.5x as long as 1M. Vein r-m 0.38–0.47x as long as 1M. 

Metasoma. TI about 1.6x as long as apical width; rugose-costate basally to areolate-rugose apically, laterally smooth, with distinct mid-longitudinal ridge; dorsal carinae short, present only basally, converging but not meeting; dorsope deep and large. Metasoma beyond petiole weakly sclerotized; TII about 1.84–1.97x longer than TIII. Ovipositor straight, 0.66–0.74x as long as hind tibia; ovipositor sheaths 0.6–0.8x longer than ovipositor.

Color. Head, mesosoma  and petiole mostly dark brown or black. Head with orange-brown spots between torulli and eyes. Mandibles orange-brown with dark brown tips. Palpi orangish yellow. Pronotum laterally and propleuron brown. Latero-dorsal corner of pronotum, mesoscutum, scutellum, mesopleuron (except dorsal ¼) including anterior corner, and petiole apically red-brown or orange-brown. Some specimens, especially smaller ones, with head mesosoma  and petiole entirely dark brown, without orangish markings; mesoscutum and scutellum varying from entirely orangish to entirely dark brown. Legs orangish yellow with light brown tarsi. Antenna dark brown, scapus ventrally and pedicel orange-brown. Metasoma beyond petiole yellowish, dorsally pale brown. Wings hyaline, veins brown.

Male. Similar to female. Body length 2.4–3.1 mm; fore wing length 2.6–3.3 mm; antenna with 29–35 segments. Petiole slender, about 2x longer than apical width.

Biology. Unknown

Comments. The new species has an elongate/slender body as compared with most species, and also a long and narrow pterostigma. It can be distinguished from other species by the unusually long pronotum, in dorsal view longer than vertex and with posterior region 3x longer than anterior. The body color, the elongate pronotum, especially the posterior region, and the relatively short vein 1-1AC resemble A. monteiroi  sp. n., which also occurs in the montane open-habitat known as campos de altitude (i.e. montane grasslands) (Martinelli & Orleans e Bragança 1996) from Itatiaia  National Park. A. longicollis  sp. n. can be distinguished from A. monteiroi  sp. n. by the very long and narrow stigma, about 6x longer than broad, as compared with less than 4x in A. monteiroi  sp. n., the pronotum black, as compared with yellow in A. monteiroi  sp. n., and the brown spots between eye and torulli, absent in A. monteiroi  sp. n.

Distribution. Montane grasslands of Itatiaia  National Park, Brazil. Altitudinal distribution ranging from 1,642 to 2,255 meters above sea level.

Etymology. From the Latin longi meaning long, and collis meaning neck, in reference to the long pronotal collar of the species.
