Description. Female. Body length: 1.43 mm (n=1).

Antenna color: antennal A1 yellow, remainder of antenna dark brown. Body color: mostly honey yellow, metasoma dark brown. Coxae color: honey yellow. Leg color (excluding the coxae): light yellow. Fore wing color: area below and after stigma infuscate, remainder of wing hyaline.

Head shape in lateral view: broad, short. Sculpture of antennal scrobe: upper half with semicircular fine ridges, otherwise smooth. Shape of torular triangle: not bulging, flat. Development of central keel on frons: completely absent. Sculpture of frons: largely smooth, with sparse setigerous punctulae. Sculpture of malar space: with fan-like striae, striae not extending into antennal scrobe. Medial surface of vertex: flat to weakly convex (normal). Size of lateral ocellus: small (as in C. bouceki ). Distance between lateral ocellus and occipital carina: 0.5–1.2x maximum ocellar width. Length of OOL: ≥ 1x width of ocellus. Sculpture of vertex: coriaceous. Surface of occiput: evenly concave (normal). Sculpture of occipital carina: strongly crenulate throughout. Proximity of occipital carina to orbital carina: well separated by distance at least 2x width of occipital carina. Shape of occipital carina: simply arcuate medially. Sculpture of occiput: with conspicuous longitudinal ridges throughout.

Sculpture of pronotal cervical area: smooth medially, otherwise with elongated foveae. Sculpture of pronotal lateral area: foveate throughout. Netrion: absent, obscured by longitudinal sculpture on lateral pronotum. Notauli: absent. Sculpture of mesoscutum: largely smooth, with sparse setigerous punctures, posterior margin with short, longitudinal striae, these shorter medially. Sculpture of mesoscutellum: mainly smooth except for granulate sculpture at anterior and lateral edge, posterior edge with dense and small foveate sculpture. Mesoscutellum shape: flat, conspicuously wider than long. Sculpture of lateral propodeum: sparsely, transversely costate. Shape of propodeal anterior spines: short, broad, apex rounded. Sculpture of propodeum between anterior spines: smooth. Sculpture of ventral mesepisternum: coriaceous. Density of longitudinal costae on dorsal mesepisternum: sparse. Thickness of longitudinal costae on dorsal mesepisternum: broad. Length of longitudinal costae on dorsal mesepisternum: reaching to meso-metapleural suture. Sculpture of mesopleural femoral depression: weakly, longitudinally foveate. Sculpture of metapleuron: largely smooth, ventral region with 2–3 longitudinal carinae.

Shape of wings: very convex in lateral view, with a conspicuous constriction at 2/5 of its length.

Shape of horn on T1 (in posterior view): narrow and short. Lateral carinae on posterior part of horn: present, rounded, not fused posteriorly. Sculpture of upper portion of T1 horn: smooth. Sculpture of posterior portion of T1 horn: smooth. Lateral carinae on T2: present, poorly developed. Sculpture of T2: largely finely costate, smooth along posterior margin and midline. Sculpture of T3: anterior 2/3 with sparse weak longitudinal carinae, midline and remainder smooth. Sculpture of S3–S6: mainly smooth, with sparse setigerous punctulae.

Male. Unknown.

Diagnosis. This species can be identified from all other species by the absence of notauli, and having a flat mesoscutellum and a very cristate and ornamented occipital carina dorsally.

Etymology. We are pleased to name this species after Jessica Diaz (wife of the first author); Thanks for the amazing Chicken liver pate!
