Deltorhinum robustum View in CoL sp. nov.
(Figs. 16–17)
Diagnosis. Differs from all others species in the genus by its large size (more than 13.5 mm) and its unmodified anterior pronotal margin.
Description. Holotype female. Body and legs reddish brown. Clypeus moderately upturned medially; median projection distinctly emarginate medially; marginal bead unmodified, weakly defined laterally. Gena acutely angular laterally. Frontal carina angulate in dorsal view, median portion noticeably lower than lateral portions. Vertex finely punctate throughout. Pronotal surface minutely punctate on disc, punctures fine on anterior and lateral declivities; pronotal median longitudinal sulcus weakly defined and shallow, present on basal two-thirds; pronotal anterior edge unmodified; pronotal anterior declivity with two triangular depressions in line with the eyes. Pronotal basal surface with larger weakly defined punctures on median half. Elytral surface finely punctate; striae fine and simple, similar on disc and apical declivity, punctures rounded and encroaching on interstriae. Elytral epipleuron unmodified, hidden in dorsal view. Protibia smooth on dorsal surface. Profemur evenly rounded anteriorly, lacking sharply defined carina on basal three-fourths. Mesofemora and metafemora simply convex ventrally. Mesotarsi and metatarsi with first tarsomere 2.5 times longer than wide at apex. Pygidial surface finely punctate throughout; basal sulcus with fine transverse microsculpture; apical marginal bead widely interrupted internally, margin distinct on basal third only.
Measurements (3 females) body length: 13.5–14.0 mm.

Etymology. Robustum , a Latin adjective referring to the relative large size of this species.
Natural history. Unknown.
Variation. The holotype is teneral, therefore lighter in color. The two other known specimens are dark brown to black with faint but distinct greenish or coppery reflections on most of the body.
