Type species. Exoplectra erythrogaster Mulsant, 1850 (original designation).

Diagnosis. Coeliaria is a Neotropical genus that resembles Exoplectra Mulsant, 1850 , and Gordonita González, 2013 , by the angulation of the tibia. Coeliaria is distinguished from Exoplectra by the presence of a fovea in the hypomera; pronotum with the inner angles more prominent and emarginated. In Gordonita , the fovea of the hypomera is small and deep; the body is elongated and depressed. Coeliaria is distinguished from the other genera of Chnoodini by the following combination of characters: Body black or dark, without spots; dorsal surface pubescent; antenna 11-segmented; labrum truncated; hypomera with rounded fovea; tibia flat and angulated; abdomen with five visible sternites (females) or six sternites (males); abdominal postcoxal line incomplete, recurved, oblique line present.

Redescription. Body rounded or oval, convex, with yellowish or whitish pubescence, fine and dense, with punctuation fine and sparse. Integument brownish or black, with green, bluish, or bronze metallic reflections, without spots. Ventral surface reddish, brown, or black. Head black or brownish; clypeus merged with forehead, without fronto-clypeal suture, expanded laterally and with rounded front edge, distinctly emarginated; eyes divided by the gena ( Figs 1, 2) partially covered by the pronotum. Antennae 11-segmented with conspicuous club ( Fig. 3). Labrum transverse, truncate anteriorly ( Fig. 4); mandibles asymmetric, robust with apex bifid ( Figs 5, 6); maxillae with last segment of palpus distinctly securiform; labium with short bristles on ligule ( Fig. 7). Pronotum transverse, narrower than elytra, anterior border emarginated with lateral margin straight, rounded above and subsinuous posteriorly. Hypomera with large, deep and rounded fovea ( Fig. 9). Prosternal process with rounded apex, without carina ( Fig. 8). Elytra expanded with projected humeral callus, with anterior margin truncate; elytral epipleuron wide, deeply excavated for reception of femoral apex, with carina parallel in the inner margin, curved at base ( Fig. 10). Legs with relatively wide femora, excavated for reception of tibiae; tibiae flattened, with acute angulation on outer margin ( Figs 11, 12); claws bifid. Abdomen with five (females) or six (males) visible ventrites, with descending post-coxal line, attached to the posterior edge of the first ventrite, with oblique line.

Male genitalia. Tegmen with penis guide and symmetrical parameres; penis slender, with developed penis capsule.

Female genitalia. Coxites elongated and sub-triangular; spermatheca C-shaped, simple.
