Chromoteleia rara Chen & Johnson  sp. n. Figures 7-8, 182-187


Body length of female: 4.68-5.30 mm (n = 20). Body length of male: 4.50-5.13 mm (n = 20). Color of A1: yellow to orange. A6 in female: as wide as long. A5 in female: distinctly longer than wide. A6 in male: as long as wide. Number of basiconic sensilla on A7: 1; 2. Number of basiconic sensilla on A12: 1. Sculpture of dorsal A1: smooth. Color of head: black. Sculpture of frons directly above interantennal process: areolate. Central keel: present only in ventral portion of frons. Ventral margin of clypeus: pointed. Granulate microsculpture of dorsal frons: absent. Occipital carina: complete. Granulate microsculpture of vertex: absent. Sculpture of occiput: smooth. Sculpture of gena: dorsoventrally strigose.

Color of mesosoma: variably orange to black. Sculpture of epicoxal lobe posterior of propleural epicoxal sulcus: smooth. Sculpture of lateral pronotal area above pronotal cervical sulcus: smooth dorsally, rugose ventrally. Sculpture of netrion: transversely striate. Microsculpture of mesoscutum: granulate. Macrosculpture of mesoscutal midlobe: punctate rugose anteriorly, sparsely punctate posteriorly. Macrosculpture of lateral lobe of mesoscutum: densely 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: smooth medially, densely punctate laterally. Shape of metascutellum: trapezoidal with broad posterior margin. Median metascutellar carina: present. Sculpture of metascutellum: rugose. Sculpture of lateral propodeal area: rugose. Sculpture of mesepisternum below femoral depression: punctate rugose. Sculpture of dorsal metapleural area: rugose. Setation of dorsal metapleural area: absent. Setation of area directly dorsal to the metapleural triangle: present. 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: black. Color of metasoma in male: black. Horn on T1 in female: present. Striae of posterior margin of T1 in female: dense. Striae of T1 in male: dense. Transverse sulcus on T2: present. 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 T7 in male: coriaceous anteriorly, densely punctate posteriorly. Posterior margin of T7 in male: straight. Sculpture of medial S2: densely longitudinally striate with fine punctures in interstices.


This species is similar to C. cuneus  , with which it shares a short postmarginal vein, and it can be distinguished by the rounded apex of T6 in dorsal view.


The epithet is inspired by the Latin word for uncommon. We apply it to this species because this species is the only species in Chromoteleia  that can have either one or two basiconic sensilla on A7. The name is treated as an adjective in apposition.

This species is extremely variable in body length, which may be an indication that it attacks multiple species with different size eggs, or that the eggs of its host(s) vary widely in size.
