Material examined.

Type material. Holotype. Female, PANAMAProvincia Panamá, Distrito de Panamá, Las Cumbres. Malaise 20.i-02.ii.1982. M. Wolda. DNA Voucher CNCHYM03459. Specimen deposited in CNC.

Diagnosis.

Eyes and ocelli appearing reddish in preserved specimens (Figs 4 A–D). Metasoma curve (Fig. 4J). Fore wing longer than body length. Vein 2M as long as (Rs+M) b. Scutellar sulcus with seven carinated foveae heterogeneous in size (Fig. 4G). Axillary trough of scutellum and axillary trough of metanotum both with complete parallel carinae (Fig. 4H).

Holotype female. Body length 4.18 mm, fore wing length 4.44 mm, hind wing length 3.43 mm.

Coloration (Figs 4 A–J). General body dark yellow, except hind leg infuscated at the base and apex of tibia; hind coxa, trochanter and trochantellus with a narrow dorsal band (Fig. 4J). Hind tarsi completely brown (Fig. 4A). Scape half basal brown and half apical yellow (Fig. 4D). Pedicel brown with yellow apical ring (Fig. 4D). Flagellum brown (Fig. 4E), ocelli and eyes appearing reddish in preserved specimens (Figs 4 A–D).

Head (Figs 4 A–D). Antenna longer than body (4.44:4.18 mm); scape longer than wide (0.22:0.16 mm); pedicel wider than large (0.12:0.10 mm); first antennal flagellomeres sub-equal in length (0.34:0.32:0.32 mm); penultimate flagellomere as same length than apical segment (0.11:0.11mm); but with flat, abruptly acute in apex. Antennal scrobes smooth, far above middle level of eyes (Fig. 4D) and carinate dorsally (Fig. 4C), median part between antennal scrobes with a short carina (Fig. 4C). Face with small, sparse and homogeneous punctures, face with a median-longitudinal carina running from antennal scrobes to clypeus (Fig. 4D), fronto-clypeal suture absent (Fig. 4D). Distance between an anterior tentorial pit and inner compound eye margin equal to diameter of a tentorial pit (0.06:0.07 mm); anterior tentorial pits far away from each other (0.24 mm) (Fig. 4D). Mandible with two teeth, inferior tooth thinner and longer than superior. Maxillary palps longer than labial palps (Fig. 4D). Distance between lateral ocellus and adjacent compound eye margin sub-equal in length to the diameter of the lateral ocellus (0.09:0.10 mm), distance between lateral ocelli shorter than diameter of lateral ocellus (0.06:0.10 mm) (Fig. 4D). Vertex narrow, medially with a smooth area, but laterally with small and sparse punctuations. Occiput slightly concaved with a short grove medially.

Mesosoma (Figs 4 A–B, G–H). Mesosoma dorsoventrally convex (Figs 4 A–B). Pronotum shiny, smooth, but curvature of pronotum with a deep grove. Mesopleuron convex, extended smooth except margins lateral and ventro-lateral that form a L-shaped region that possesses small, dense and homogeneous punctuations (Fig. 4B); mesopleuron with a deep dent just above of L-shaped area, demarcating the border of the area with elongate foveae (Fig. 4B). Mesosternum slightly flat with a median row of foveae. Metepisternum and metepimeron separated by a groove with several deep foveae throughout (Fig. 4B), metepisternum smooth and narrower than metepimeron, apical margin metepisternum just above hindcoxa outlined by a wide, flat carina (Fig. 4B). Mesoscutum as wide as head, with small, sparse and homogenous punctures. Notauli clearly impressed, but not reaching the transscutal articulation (Fig. 4G). Scutellar sulcus with seven deep, carinated foveae of heterogeneous size (Fig. 4G). Scutellum shiny with fine, sparse punctures and delimited by carina. Axillary trough of scutellum and axillary trough of metanotum both with vertical parallel carinae (Fig. 4H); space among ATM carinae wider than ATS carinae (Fig. 4H). Lunule of scutellum and medioposterior band of scutellum smooth and shiny (Fig. 4H). Medioposterior band of metanotum and medioanterior pit of metanotum forming a pentagonal-shaped delimited by carinae (Fig. 4H). Posterior rim of metanotum thin and smooth (Fig. 4H). Propodeum with a complete median-longitudinal carina dividing the propodeum in two halves, each half with one additional carina that does not branch basally at the same point than median-longitudinal carina (Figs 4 H–I); space between median and an additional carina wider as they become more distant from propodeal foramen (Figs 4 H–I), and all three carinae crossed by transverse semicircular carinae, although apically less transverse carinae than basally.

Wings (Fig. 4A). Fore wing with vein r straight (0.27 mm), arising just beyond middle of stigma; vein 2RS longer than 2M and (Rs+M) b veins (0.24:0.10:0.10 mm). Hind wing with vannal lobe reduced, slightly convex; edge with sparse setae throughout. Costal and basal cell infuscate.

Legs (Figs 4A, F, I–J). Hind coxa reaching apex of tergite III (Fig. 4I), outer dorsal surface of hind coxa with an area delimited by a strong longitudinal carina running from base to apex, but last third apically the carina turns inward (Fig. 4I); area surrounded by the carina with rugulose punctuations that are more visible in dorsal view, and with an additional basal carina which splits and runs only the first third basally (Fig. 4I); hind tibia with outer spur half as long as inner spur (0.36:0.72 mm); inner spur more than half as long as hind basitarsus (0.72:0.92 mm) (Fig. 4F); outer dorsal side of hind tibia moderately spinose (Fig. 4F).

Metasoma (Figs 4A, I–J). Petiole of tergite I narrow (Fig. 4I), length 0.52 mm, distinctly constricted at anterior half (minimum width 0.10 mm), but subapically wider (maximum width 0.26 mm); petiole with a deep groove extending more of two thirds tergite I length (Fig. 4I); hypopygium not protruding beyond apex of metasoma (Fig. 4J), hypopygium plate with truncate apex (Fig. 4J); ovipositor sheaths length 0.36mm, glabrous, with apex rounded protruding apex of metasoma (Fig. 4A, J)
