Abstract
A new species of Melzerella Lima is described from Santa Cruz Department, Bolivia. A key to the four known species is provided, along with color photographs documenting their vibrant patterns. The genus Melzerella Lima, 1931 contains some of the moststrikingly colored and patterned Cerambycidae in the world. They are collected uncommonly and most specimens have been taken at lights. The genus was proposed by Lima (1931), based on-M lutzi which was described from Brazil. Lima indicated that the genusfit the tribe Aeren-icini (Lamiinae) based on the open mesocoxal cavities; third abdominal ventrite much shorter than either the first or fifth; eyes undivided; head not retractile, and presence of bifid tarsal claws. He defined the genus based on the elongate, cylindrical body; short, vertical frons; large, deeply emarginate eyes with lower lobes larger than upper lobes; short genae; cylindrical prothorax without lateral tubercles, and elongate, truncate elytra possessing dentiform or spinose processes at the suture and apicolaterad. Subsequently, a second species, M. costalimai from Venezuela, was described by Seabra (1961). A third species, M. huedepohli from Bolivia, was described by Monne (1979).
