Zamodes

Zamodes obscurus is a species of beetle in the family Cerambycidae, the only species in the genus Zamodes, described by John Lawrence LeConte in 1873 from a single specimen collected in Pennsylvania, currently stored at the Museum of Comparative Zoology, Harvard University, which remains the only specimen in existence, and the species is presumed to be extinct. It belongs to the tribe Hesperophanini.

Antenna (male) a little longer than the body, punctured, finely pubescent, hispid with numerous long, erect flying hairs, thicker at the base, gradually attenuated externally, not sulcate nor carinated, 3d joint a little longer than the 4th, the latter and following ones nearly equal, 11th very feebly appendiculate. Prothorax rounded on the sides, constricted at the basal margin, without dorsal callosities. Elytra parallel, rounded at tip. Front coxal cavities round, not at all angulated externally ; open behind, presternum very narrow between the coxse ; middle coxae rather widely separated, scarcely angulated externally, rneso- sternura subtriangular, emarginate behind ; metathorax emarginate behind, episterna narrow, scent pores not distinct ; ventral segments equal, 1st a little longer, 5th rounded at tip, 6th not visible.
