Material examined.

Type material. Holotype. Male, COLOMBIA Magdalena, PNN [Parque Nacional Natural] Tayrona Pueblito, lat 11.33333, long -74.03333, 225m, Malaise, 03-22.i.2001, R. Henriquez leg. M.1212. Paratype. 1 Male, COLOMBIA Chocó, PNN [Parque Nacional Natural] Utría, Cocalito, 6°1'N, 77°20'W, 20m, Malaise, 26.xii.2000-01.ii.2001, J. Pérez, Leg. M.1342. Holotype and paratype deposited in IAvH-E.


Eyes and ocelli silver (Figs 3 A–D, F). Scutellar sulcus with five deep, heterogeneous and carinated foveae (Fig. 3E). Axillary trough of metanotum with a few striated grooves defined at least posteriorly (Fig. 3G). Body longer than fore wing (Fig. 3A).

Holotype male. Body length 4.30 (4.30-4.55 mm), fore wing length 4.15mm, hind wing length 3.59 mm.

Coloration (Figs 3 A–L). General body dark yellow; all legs yellow, except hind leg: coxa infuscated at the apex forming a ventral, wide brown band; apex of trochanter, and trochantellus, base of tibia and tarsi brown (Fig. 3A). Scape and pedicel brown both with thin apical yellow ring. Flagellum dark brown. Eyes and ocelli silver (Figs 3 A–D, F.) Tergite IV and beyond mostly brown, but subapically and subbasally with a transverse yellow band (Figs 3I, L). Membrane and microtrichiae of fore and hind wing infusctate (Figs 3 J–K).

Head (Figs 3 A–D). Scape slightly longer than wide (0.20:0.18 mm); pedicel wider than long (0.12:0.08 mm); first three flagellomeres subequal in length (0.32:0.30:0.34). Antennal scrobes smooth, dorsally carinate (Fig. 3B), positioned far above middle level of eyes (Figs 3 C–D); median part between antennal scrobes with a short carina (Fig. 3B). Face with sparse, homogeneous and medium-sized punctures, interspaces wavy; face with a median-longitudinal carina running from antennal scrobes to fronto-clypeal suture (Fig. 3D). Distance between each anterior tentorial pit and closest inner compound eye margin longer than diameter of tentorial pit (0.10:0.06 mm) (Figs 3 C–D); anterior tentorial pits far away from each other (0.26 mm) (Fig. 3C). Fronto-clypeal suture absent (Figs 3 C–D). Mandible with two teeth, inferior tooth thinner and longer than superior (Fig. 3C). Suture malar present (Fig. 3D). Maxillary palps longer than labial palps (Fig. 3C). Distance between lateral ocellus and adjacent compound eye margin longer than diameter of lateral ocellus (0.11:0.08 mm) (Fig. 3B), distance between lateral ocelli equal to diameter of lateral ocellus (0.08:0.08 mm) (Fig. 3B). Vertex medially smooth, but laterally with some sparse and small punctuations. Occiput slightly concave with a median short grove basally.

Mesosoma (Figs 3A, E–G). Mesosoma dorsoventrally convex (Figs 3A, F). Pronotum shiny, smooth, but curvature of pronotum with elongate areolae. Mesopleuron shiny, smooth medially, but margins lateral and ventro-lateral forming a L-shaped area which small, dense and homogeneous sculptures (Fig. 3F); mesopleuron just above of L-shape area with a dent with some large wave-like sculpturing. Mesosternum slightly flat with a deep row of deep foveae. Metepisternum and metepimeron outlined by a groove with several deep foveae throughout (Fig. 3F), metepisternum inverted triangular, smooth and narrower than metepimeron (Fig. 3F), apical margin metepisternum (above hindcoxa) delimited by a wide, flat carina (Fig. 3F). Mesoscutum as wide as head with small, dense, and homogenous sculptures. Notauli clearly impressed, but not reaching the transscutal articulation (Fig. 3E). Scutellar sulcus heterogeneous, with five deep, heterogeneous and carinated foveae (Figs 3E, G). Scutellum shiny, medially smooth, but with sparse fine punctures and surrounded by carina (Figs 3E, G). Axillary trough of scutellum with several homogeneous striated grooves (Fig. 3G). Axillary trough of metanotum with a few striated grooves defined at least posteriorly (Fig. 3G). Medioposterior band of scutellum slightly wider than lunule of scutellum both smooth and shiny (Fig. 3G). Medioposterior band of metanotum hexagonal and crossed by a median carina aligned with the median longitudinal carina of propodeum (Fig. 3G). Medioanteror pit of metanotum pentagonal-shape surrounded by carina (Fig. 3G). Posterior rim of metanotum thin, wavy and smooth (Fig. 3G). Propodeum with a complete median-longitudinal carina dividing in two halves, each half with one divergent carina wider as they go away from propodeal foramen, space among all carinae intercepted by transverse semicircular carinae (Fig. 3G).

Wings (Figs 3A, J–K). Fore wing with vein r length 0.26 mm slightly curved, arising beyond middle of pterostigma, arising just beyond middle of stigma (Fig. 3J); vein 2RS as same length as r (0.26:0.26 mm),but 2RS vein longer than 2M and (Rs+M) b veins (0.26:0.10:0.20 mm) (Fig. 3J). Hind wing with vannal lobe reduced, slightly convex; edge with sparse setae throughout (Fig. 3K). Costal and basal cells infuscate (Fig. 3K).

Legs (Figs 3A, H, L). Hind coxa very long, reaching apex of tergite III (Fig. 3H), outer dorsal surface of hind coxa delimited by a strong carina, area coarsely rugulose and with a short, strong basal carina (Fig. 3H); hind tibia with outer spur more than half as long as inner spur (0.40:0.66 mm), inner more than half as long as hind basitarsus (0.66:0.88 mm) (Fig. 3A), hindtibia and tarsi with spines throughout.

Metasoma (Figs 3A, H–I, L). Petiole of tergite I narrow (Fig. 2H), length 0.70 mm, distinctly constricted at upper middle (minimum width 0.09 mm) and wider subapically (maximum width 0.20 mm) with sculpturations, petiole with a deep groove extending more of two third of the tergite I length (Fig. 3H). Male genitalia externally visible (Fig. 3I).

Female. Unknown


From Kogui = jaguar in the Kogui language. The Kogui are indigenous in the Colombia Caribbean coast at the foot of the Sierra Nevada de Santa Marta, the highest coastal mountains in the world and not directly attached to the Andean mountain range.


Colombia, from PNN Tayrona and PNN Utría, both being marine ecosystems protected by the Colombian government and belonging to the National Natural systems. Tayrona is located on the Caribbean coast in Magdalena Department, whereas Utría is located on Colombia’s Pacific coast, in Chocó Department.




Holotype lacks the last antennal flagellomeres. The specimens from Utría with antennae length = 4.8 mm, body length 4.3 mm. Last antennal flagellomere length = 0.35 mm, penultimate flagellomere antennae length = 0.30 mm. Male from Chocó shows hind legs with the same pattern of coloration but darker and Tergite VI and beyond with brown spots (Fig. 3L).
