Body color ( Fig. 1 View FIGURE 1 A): mainly black. Flagellomeres dark brown. Scape and pedicel dark brown, but with a slender light brown stripe at the apex. Annellus light brown. Labrum and mandible red-brown. Labial and maxillary palps yellow-brown. Legs yellow-brown except hind tibia and hind tarsus brown. Fore wing ( Fig. 1 View FIGURE 1 G): tegula yellow, but with a central, rounded, light brown spot; stigma dark brown. Membrane of fore and hind wings light brown; microtrichiae of fore wings brown, hind wings hyaline.
Head ( Figs. 1 View FIGURE 1 A–D). — Subquadrate ( Fig. 1 View FIGURE 1 B). Antenna with 12 flagellomeres; first three flagellomeres longer than wide (0.20:0.07; 020:0.07; 0.18: 0.07 mm), last five, except the last one, longer than wide (0.09:0.06; 0.09:0.06; 0.09: 0.06; 0.10: 0.06; 0.11: 0.06 mm); apical flagellomere longer than penultimate segment (0.14: 0.09 mm); scape shorter than first flagellomere (0.15: 0.20 mm) and wider than first flagellomere and pedicel (0.09:0.07: 0.07 mm); pedicel less than half as long as scape (0.06: 0.15 mm) ( Fig. 1 View FIGURE 1 A). Torulus located above midline of the eye ( Fig. 1 View FIGURE 1 B). Frons short with a deep longitudinal median groove enclosed by two lateral carinae, each of which runs to ventral margin of lateral ocelli, but without touching each other; groove next to median ocellus with an N-shaped carina, ventrally narrower than anteriorly, running from midline of low face to ventral margin of lateral ocelli. Scrobes shallow, wide, not surrounded by a carina, with large areolae, scrobes reaching the dorsal part of median ocellus ( Fig. 1 View FIGURE 1 C). Lower face larger than frons, flat or nearly so, without protuberance ( Fig. View FIGURE 1
1B), with dense, small sculptures although dorsally with semicircular interspaces. Fronto-clypeal suture strongly impressed, rounded, with sculpture. Anterior tentorial pit embedded within a strong depression. Clypeus convex ( Fig. 1 View FIGURE 1 B), with small, dense punctation; interspaces wide, smooth; apical part slightly reflexed, narrow, smooth, shiny without a defined edge although basally with a strong carina. Labrum with sparse, small punctates; interspaces wide, smooth. Mandible long, slender with transverse strigae; mandible set with two teeth, superior teeth longer than inferior; with sharp apex. Maxillary palps longer than labial ( Fig. 1 View FIGURE 1 B). Ocelli oval, lateral ocelli distant from each other, separated by more than the width of lateral ocelli (0.08: 0.05 mm) ( Fig. 1 View FIGURE 1 C); area between lateral ocelli surrounded by a high edge. Stemmaticum elevated relative to vertex with a high longitudinal lamella between median ocellus but hiding the lateral ocelli, lamella smooth, shiny with rounded apex, wide base with sparse heterogeneous areolaes; elevation of stemmaticum convex. Eyes without preorbital carina ( Fig. 1 View FIGURE 1 B). Vertex with large, irregularly rugose areolae ( Fig. 1 View FIGURE 1 C), vertex without longitudinal median carina. Occiput concave, smooth, shiny. Occipital carina present and complete ( Fig. 1 View FIGURE 1 C). Temple and gena with heterogeneous areolae.
Mesosoma ( Figs. 1 View FIGURE 1 A–D, F). — Projection of propleuron blunt. Pronotum concave ( Fig. 1 View FIGURE 1 D); anteriorly with a smooth area throughout and with a row of large areolae; curvature of pronotum with elongate areolae; posteriorly with a mix of small areolae and small punctures close to pronotal lobe. Pronotal lobe sloped toward tegula; point of inflection carinated; apex rounded ( Fig. 1 View FIGURE 1 D). Mesoscutum uneven, median lobe higher than lateral lobes ( Fig. 1 View FIGURE 1 C); lateral mesonotal lobes with small, sparse punctures; interspaces wide, shiny; anteriorly sloped and posteriorly convex, edge of lateral mesonotal lobes with homogeneous foveae throughout ( Fig. 1 View FIGURE 1 C); median mesonotal lobe with two carinae: a continuous longitudinal median carina which is less than half as long as median mesonotal lobe, and a continuous anterior-transverse carina that runs from one end to the other with an elevation in the middle ( Figs. 1 View FIGURE 1 C–D); antero-lateral parts of median lobe with some transverse carinae; area of convergence of notauli with large areolae forming an inverted triangle. Notauli strongly impressed with large, elongate foveae throughout and without additional row of foveae; notauli near edge of transscutal articulation ( Fig. 1 View FIGURE 1 C). Scutellum slightly convex with heterogeneous areolae; scutellum at same height as mesoscutum ( Fig. 1 View FIGURE 1 D); middle part with a longitudinal carina, posteriorly sloped, but on same vertical plane as posterior scutellar depression; scutellar sulcus with four uneven and deep foveae; posterior scutellar depression with two square foveae that fill most of the smooth area. Middle part of metanotum below posterior scutellar depression without projection. Propodeum antero-posteriorly short, symmetrical; crossed totally by MLC ( Fig. 1 View FIGURE 1 F) and posteriorly MLC with a conspicuous projection ( Fig. 1 View FIGURE 1 D); ATC making an invagination and later reaching the same length as MLC; AMA absent ( Fig. 1 View FIGURE 1 F); posterior wall of propodeum flat ( Fig. 1 View FIGURE 1 F) with small areolae and wide interspaces. Metapleuron with areolae heterogeneous in shape and size ( Fig. 1 View FIGURE 1 D). Mesopleuron with epicnemial carina ( Fig. 1 View FIGURE 1 D), but without sternaulus; mesopleuron convex; central area shiny with sparse, small punctures; dorsally with transverse furrow below the tegula, with large areolae forming a second row of sculptures; ventrally with deep, elongate, diagonal dent with large areolae; anteriorly with an elongate, narrow, flat area that bears small, dense punctures throughout the edge; posteriorly scrobiculate. Mesosternum flat with only two posterior thirds with a central row of foveae surrounded by carinae; lateral parts delimited by two carinae at each side, straight inner lateral carina close to central row, outer carina oblique; both carinae intercepted in the posterior third; mesosternum near fore coxa forming a high transverse lamella with two elevations of same height, located below each fore coxa; mesosternum near mid coxa with areolae of different sizes, with smooth semicircular area above mid coxa which is intercepted by the junction of both lateral carinae.
Wings ( Figs. 1 View FIGURE 1 A,G). — Fore wing ( Fig. 1 View FIGURE 1 G): vein M+CU markedly curved (sinuate); vein 3RSb tubular, distant from stigma (0.45 mm); subbasal cell longer than basal (1.08: 0.97 mm); stigma short, relatively rounded. Fore wing: length 2.27 mm, width 0.87 mm; hind wing: length 1.57 mm, width 0.57 mm.
Metasoma ( Fig. 1 View FIGURE 1 A–E). — Carapace in lateral view teardrop-shaped ( Fig. 1 View FIGURE 1 A); anteriorly with strong substrigulae that cross more than half the length of the carapace; area between the carinae lacunose. Apex of carapace with two tubercles and above them in the middle with one protuberance; apex convex, smooth and shiny; tubercles asymmetric (Length 0.18: 0.14 mm) with sharp apex ( Fig. 1 View FIGURE 1 E); tubercles separated by more than twice the width of the base of the tubercle (0.18: 0.07 mm). Ovipositor ( Fig. 1 View FIGURE 1 A) length 1.7 mm. Carapace length 1.55 mm.
Male.— Unknown.
Biology.— Unknown.
Comments.— Dorsal edge of posterior wall of metanotum with a semicircular shape.
Material examined.— Holotype, female, Colombia: Bolívar, SFF [Santuario de Fauna y Flora] Los Colorados, Villa Roca, 9º54´N 75º7´W, 180m, Malaise, 23.v.-7.vi.2001, E. Deulufeut leg., M. 1723, IAvH-E 64532. Deposited in IAvH-E.
Etymology.— From alius (Latin, adjective) = another, other, different and longitudo (Latin, noun, femenine) = length. The name refers to the different length of the two tubercles in the apex carapace.
