(Figs 23–29, 31, 81)
Diagnosis. Body dark brown dorsally with honey yellow spot from mid posterior mesoscutum until scutellum, laterally and ventrally honey yellow (whitish in males), head honey yellow, vertex and frons frequently brown or dark brown; occiput strongly receding dorsally; occipital carina complete dorsally, far apart from hypostomal carina ventrally; small eyes, in dorsal view 1.6 times longer than temple; female flagellomeres moderately compact, 10th flagellomere 1.6 times longer than wide; fore wing vein 1-CU1 about as long as vein cu-a; hind wing vein m-cu present and pigmented, interstitial to vein r-m; vein RS virtually straight; dorsal carina forming semicircular area at base of petiole; petiole with unusually long and acute basal lateral flanges, pointed backward.
Description of holotype. ♀, body length 4.1 mm, fore wing length 3.1 mm, antenna length around 4.3 mm.
Head. Antennal segments 37, antenna relatively short, 1.4 times as long as fore wing, third segment as long as fourth segment, length of third, fourth and penultimate antennal segments 1.8, 1.8 and 1.5 times their width, respectively; length of maxillary palpi 1.3 times height of head; eyes small, length of eye in dorsal view 1.6 times temple; head sculpturing shining granulate, face and temples smoother but also granulate; occipital carina complete dorsally, ventrally not meeting hypostomal carina, occiput receding dorsally; POL:OD:OOL = 3:4:7; face with weak median crest; clypeus slightly protruding in lateral view; oral opening 0.38 times width of face; malar space large, 2.0 times longer than basal width of mandibles and 0.6 times eye height in frontal view; frons without lateral carina; eyes with inner margin weakly indented.
Mesosoma. Length of mesosoma 1.8 times its height; surface sculpturing mostly granulate; pronotum smooth and polished ventrally, pronotal groove almost entirely crenulate; mesopleuron with rugose subalar groove; precoxal sulcus rugose, shallow and wide anteriorly; middle lobe of mesoscutum without distinct antescutal depression, pronotal collar very short with a transverse rugosity; notauli deep and crenualte anteriorly, meeting posteriorly in flat area; scutellar sulcus granulate anteriorly, with complete mid-longitudinal carina; scutellum granulate; propodeum coarsely granulate on basal lateral areas, granulate-rugose otherwise, longitudinal carina complete, although irregular posteriorly; ventral midline of mesopleuron set within shallow and smooth sulcus.
Wings. Fore wing: vein r-m present, second submarginal cell trapezoidal, vein 3-SR 0.9 times longer than 2M; r:3- SR:SR1:2-SR:2-SR+M = 15:16:54:13:11; vein 1-SR+M virtually straight; 1-M slightly and evenly curved; 1- CU1:2-CU1:cu-a = 5:27:4. Hind wing: vein cu-a short and only slightly reclivous; M+CU:1-M:1r-m = 7:19:10; vein RS virtually straight, gradually away from wing margin; vein m-cu present and interstitial to vein r-m.
Legs. Tarsal claws not pectinate, with several setae basally, its apical tooth angularly bent; hind coxa granulate; femur, tibia and basitarsus of hind leg 5.4, 10.5 and 8.8 times their width, respectively; length of inner hind tibial spurs 0.27 times hind basitarsus; hind tarsi about as long as hind tibia.
Metasoma. Petiole apical width 2.0 times longer than basal width, length of first tergite 1.47 times its apical width; first tergite coarsely areolate-rugose, mid-longitudinal carina indistinct; second tergite finely areolate (appearing granulate without proper light and magnification), mid-longitudinal carina present only centrally and very weak; third tergite shining coriaceous, with convex outline; remaining tergites largely smooth; length of second tergite 1.3 times median length of third tergite; ovipositor sheaths very short, 0.75 times shorter than hind tarsomere II, with apical projections very thin and translucent, somewhat shrunk and difficult to see; dorsal carina forming semicircular area at base of petiole; base of petiole with lamelliform lateral flanges.
Color. Body dark brown dorsally with honey yellow spot from mid posterior mesoscutum until scutellum, laterally and ventrally honey yellow, head honey yellow, stemmaticum dark brown; metasoma beyond tergum 3 yellow. Antenna with scapus and pedicel brown, flagellum dark brown, lightening apically, apical segments whitish.
Variation. Color of vertex brown in some female paratypes; body size 4.1–4.7 mm; antennomeres 39–41; longitudinal carina on first and second tergite better defined in the paratypes; the apical projections of ovipositor sheaths are not visible in one of the three female paratypes, in the other two they are clearly present, although thin and translucent.
Male. Slenderer antenna and less white antennomeres at apex, around 6–8, as compared with 14–16 in females. The body laterally and ventrally, legs and part of head of males and are whitish, as compared with yellow in females.
Distribution. Known from type locality in Chocó department, Parque Nacional Natural Utría, Colombia.
Type material. Type-locality: COLOMBIA, Chocó department, Parque Nacional Natural Utría, Cocalito, elevation 20m, 6º1’N 77º20’W, December 26, 2000 – February 1, 2001, Malaise trap. Type-specimen: HOLOTYPE ♀ (IAVH #149969), point mounted. Top label: “ COLOMBIA: Chocó PNN /Utría Cocalito 20m / 6º1’N 77º20’W Malaise / 26.XII.00 – 1.II.2001 / J. Pérez Leg. M1342”; bottom label “Instituto Humboldt Colombia / IAVH-E-149969”. PARATYPES. 4 ♀s and 9 Ƌs. 7Ƌ (IAVH #149968, #149970–149975), same as holotype; 2♀ (IAVH #149966, #149967), same as holotype, “Cocalito Dosel”, M1340; 1♀ (IAVH #42619), same as holotype, Centro de Visitantes, M1343; 1♀ (IAVH #149979) and 2Ƌ (IAVH #149978, #149980), same as holotype, 30.X– 26.XII.2000, M1344.
Discussion. This species is very similar to A. tico sp. nov. by having a dorsally complete to only shortly interrupted occipital carina, as well as similar color pattern and sculpturing of body. However, in A. choco sp. nov. the mesopleuron and metapleuron are entirely whitish or yellowish, as compared with entirely dark brown in A. tico sp. nov. It also differs in the taller basal cell on hind wing, where vein 1M is about 1.85 times longer than vein r-m, as compared with 2.5–3.0 times longer in A. tico sp. nov. The female flagellomeres are less compact than in A. tico sp. nov., 10th flagellomere is about 1.6 times longer than wide in A. choco sp. nov., as compared with about as long as wide in A. tico sp. nov., and the occipital carina is distinctly apart from hypostomal carina ventrally, while in A. tico sp. nov. the occipital carina meets the hypostomal carina.
Etymology. The species name is a reference to the Department of Chocó in Colombia, where the type specimens were collected.
