Body length of female: 4.20-4.80 mm (n = 16). Body length of male: 4.30-4.67 mm (n = 17). Color of A1: yellow to orange. A6 in female: distinctly wider than long. A5 in female: distinctly longer than wide. A6 in male: as long as wide. Number of basiconic sensilla on A7: 1. Number of basiconic sensilla on A12: 1. Sculpture of dorsal A1: punctate. Color of head: black. Sculpture of frons directly above interantennal process: transversely striate to rugose. Central keel: present, interrupted medially. Ventral margin of clypeus: straight. Granulate microsculpture of dorsal frons: present. Occipital carina: complete. Granulate microsculpture of vertex: present. Sculpture of occiput: smooth. Sculpture of gena: coarsely punctate rugose.

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 throughout. Sculpture of netrion: transversely striate. Microsculpture of mesoscutum: granulate. Macrosculpture of mesoscutal midlobe: sparsely punctate. 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: granulate. Shape of metascutellum: elongate trapezoidal but with deeply incised apex, forming two spines laterally. Median metascutellar carina: absent or indistinguishable from sculpture. Sculpture of metascutellum: rugose. Sculpture of lateral propodeal area: rugose. Mesopleural carina: absent. Sculpture of mesepisternum below femoral depression: punctate rugose. Sculpture of dorsal metapleural area: rugose; obliquely striate. Setation of dorsal metapleural area: present. Setation of area directly dorsal to the metapleural triangle: present. Sculpture of ventral metapleural area: rugose throughout. Color of legs: orange yellow to brown, with tarsi darker. Length of hind basitarsus: about as long as remaining segments combined. Sculpture of hind coxa: densely punctate.

Length of postmarginal vein: approximately as long as stigmal vein.

Color of metasoma in female: black. Color of metasoma in male: black. Horn on T1 in female: absent. Striae of posterior margin of T1 in female: sparse. Striae of T1 in male: sparse. Transverse sulcus on T2: present. Sculpture of T2: densely longitudinally striate, punctate rugulose in interstices. Sculpture of T6 in female: longitudinally punctate rugose. Length of T6 in female: approximately as long as wide. Shape of T6 in female in lateral view: sinuate. Apical spine on female T6: present. Sculpture of T6 in male: densely punctate. Sculpture of T7 in male: smooth anteriorly, rugulose posteriorly. Posterior margin of T7 in male: bispinose. Sculpture of medial S2: densely longitudinally striate with fine punctures in interstices.


This species is easily recognized by its bispinose metascutellum, a character not found in any other species of Chromoteleia  .


The epithet is inspired by the Latin word for two-toothed, in reference to the bispinose metascutellum, and is intended to be treated as a noun.
