Description.

Body length of female: 5.38-5.70 mm (n = 20). Body length of male: 4.90-5.15mm (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: 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: areolate. Central keel: present, interrupted medially. 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: punctate rugose dorsally and ventrally, strigose medially.

Color of mesosoma: variably orange to nearly black. Sculpture of epicoxal lobe posterior of propleural epicoxal sulcus: densely punctate. Sculpture of lateral pronotal area above pronotal cervical sulcus: smooth dorsally, rugose ventrally. Sculpture of netrion: rugose. Microsculpture of mesoscutum: absent. 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: absent or indistinguishable from sculpture. Sculpture of metascutellum: areolate. Sculpture of lateral propodeal area: 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: 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: largely smooth, with sparse fine punctures.

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: sparse. 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 T6 in male: densely longitudinally striate with fine punctures in interstices. Sculpture of T7 in male: granulate. Posterior margin of T7 in male: emarginate medially between rounded projections. Sculpture of medial S2: densely longitudinally striate with fine punctures in interstices.

Diagnosis.

This species is similar to C. copiosa , but it can be distinguished by the combinations of the following characters: occipital carina complete, netrion rugose, and the hind basitarsus approximately as long as the remaining segments combined.

Etymology.

The epithet is inspired by the Latin word for scattered, in reference to the sparsely punctate posterior part of mesoscutum, and is intended to be treated as an adjective.
