Synonyms: Conocephalus latipennis (Walker 1869) : 378, and Conocephalus fuscipes ( Redtenbacher 1891) : 421.

Body size: 31–33 mm (male); 36–40 mm (female).

Head: in dorsal view, almost triangular, slightly longer in midline than wide about 1:0.8, shorter than pronotum in length about 1:1.8, head slightly narrower than pronotum about 1:1.3, median length of fastigium shorter than width about 1:1.4, vertex longer than fastigium about 1:0.3; dorsal width of vertex two times wider than antennal scape; compound eyes spherical, prominent.; in lateral view, fastigium without ventral carina, slightly elongate, rounded at the tip; notch between fastigium and frons closed (occasionally open), basal and apical process absent; in anterior view, lateral margins of frons slightly arched and slightly divergent apically; face wider than width at level of eye about 1:0.7.

Thorax: Pronotum without lateral carinae; in lateral view, dorsal and ventral margin straight, median height shorter than median length about 1:1.5, posterior margin without marked invagination; in dorsal view, narrower anteriorly, slightly convergent towards head.

Tegmina cover abdomen, but in female not the tip of the ovipositor, rather rounded at the tip; male stridulatory rib characteristic with thin teeth present; male mirror of the right tegmen ovoid with a stridulatory file.

Genitalia: Ovipositor straight, slender and narrowing towards the apex, usually as long as hind femur. Cerci cylindrical with perpendicular bending inwardly. Tenth tergite rather concave with straight styli, not projecting beyond cerci.
