Description.

Body length of female: 3.38-3.65 mm (n = 5). Color of A1: yellow to orange. A6 in female: distinctly wider than long. A5 in female: as long as wide. Number of basiconic sensilla on A7: 1. 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: complete, extending from interantennal process to median ocellus. Ventral margin of clypeus: pointed. Granulate microsculpture of dorsal frons: absent. Occipital carina: complete. Granulate microsculpture of vertex: absent. Sculpture of occiput: smooth medially, striate laterally. Sculpture of gena: coarsely punctate rugose.

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: 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: flat. 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. 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: about as long as remaining segments combined. Sculpture of hind coxa: densely punctate.

Length of postmarginal vein: distinctly shorter than stigmal vein.

Color of metasoma in female: black. Horn on T1 in female: absent. Striae of posterior margin of T1 in female: dense. 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: flat. Apical spine on female T6: absent. Sculpture of medial S2: densely longitudinally striate with fine punctures in interstices.

Diagnosis.

This species is similar to C. curta , but it can be distinguished by the combination of the following characters: A5 in female as long as wide, postmarginal vein distinctly shorter than stigmal vein, female T1 horn absent.

Etymology.

The epithet is inspired by the Latin word for small, in reference to the small body size of this species, and is intended to be treated as a noun.
