Chromoteleia congoana (Risbec)  Figures 48-51, 52-57

Oxyscelio congoana  Risbec, 1950: 613 (original description).

Chromoteleia congoana  (Risbec): Masner, 1976: 25 (description, generic transfer, type information); Johnson, 1992: 364 (cataloged, type information).


Body length of female: 4.38-5.66 mm (n = 20). Body length of male: 4.10-4.78 mm (n = 4). Color of A1: yellow to orange. A6 in female: as wide as long. A5 in female: distinctly longer than wide. A6 in male: approximately 2.0 × longer than wide. Number of basiconic sensilla on A7: 1. Number of basiconic sensilla on A12: 1. Sculpture of dorsal A1: punctate; smooth. Color of head: black. Sculpture of frons directly above interantennal process: punctate rugose. Central keel: complete, extending from interantennal process to median ocellus. Ventral margin of clypeus: pointed. Granulate microsculpture of dorsal frons: present. Occipital carina: complete. Granulate microsculpture of vertex: present. Sculpture of occiput: rugose. Sculpture of gena: punctate rugose dorsally and ventrally, strigose medially.

Color of mesosoma: variably orange to black. Sculpture of epicoxal lobe posterior of propleural epicoxal sulcus: sparsely punctate. Sculpture of lateral pronotal area above pronotal cervical sulcus: smooth dorsally, rugose ventrally. Sculpture of netrion: punctate rugose anteriorly, smooth posteriorly. Microsculpture of mesoscutum: coriaceous. Macrosculpture of mesoscutal midlobe: punctate rugose anteriorly, sparsely punctate posteriorly. Macrosculpture of lateral lobe of mesoscutum: sparsely punctate. Sculpture of notaulus: foveate. Notaular foveae: interconnected. Median mesoscutal carina: present anteriorly, not extending to posterior margin of mesoscutum. Mesoscutellum in lateral view: convex. Sculpture of mesoscutellum: sparsely punctate. Shape of metascutellum: trapezoidal with broad posterior margin. Median metascutellar carina: absent or indistinguishable from sculpture. Sculpture of metascutellum: rugose. Mesopleural carina: present. Sculpture of mesepisternum below femoral depression: punctate throughout. Sculpture of dorsal metapleural area: rugose. Setation of dorsal metapleural area: absent. Setation of area directly dorsal to the metapleural triangle: absent. Sculpture of ventral metapleural area: rugose throughout. Color of legs: orange yellow throughout. Length of hind basitarsus: distinctly longer than remaining segments combined. Sculpture of hind coxa: densely punctate.

Length of postmarginal vein: distinctly shorter than stigmal vein.

Color of metasoma in female: dark brown. Color of metasoma in male: dark brown to black. Horn on T1 in female: present. Striae of posterior margin of T1 in female: dense. Striae of T1 in male: sparse. Transverse sulcus on T2: absent. Sculpture of T2: densely longitudinally striate, punctate rugulose in interstices. Sculpture of T6 in female: densely longitudinally striate, with fine punctures in interstices. Length of T6 in female: at least 1.5 × longer than wide. Shape of T6 in female in lateral view: flat. Apical spine on female T6: absent. Sculpture of T6 in male: densely longitudinally striate with fine punctures in interstices. Sculpture of T7 in male: smooth anteriorly, rugulose posteriorly. Posterior margin of T7 in male: emarginate medially between rounded projections. Sculpture of medial S2: densely longitudinally striate with fine punctures in interstices.


This species can be distinguished from other Chromoteleia  species by the following combination of characters: median mesoscutal carina only present anteriorly, mesosoma variably orange to black, postmarginal vein distinctly shorter than stigma vein, T2 without transverse sulcus, male T7 with posterior margin deeply emarginated between rounded projections.
