Etymology. Capixaba is the gentilic of people born in the Brazilian state of Espírito Santo, the state of the type locality of the new species.

Remarks. Lepturdrys capixaba sp. nov. differs from L. novemlineata only by the elytral pubescent pattern: without longitudinal pubescent bands or with sparse and partial longitudinal pubescent bands; without subcircular whitish pubescent macula dorsally just after middle; and the large whitish pubescent macula dorsally on anterior half is projected backward. In L. novemlineata , the elytra have abundant longitudinal pubescent bands, including on the large patch of whitish pubescence on the anterior half, there is a subcircular whitish pubescent macula dorsally after middle, and the large whitish pubescent macula dorsally on anterior half is not projected backward. All these areas of pubescence are constant in the holotype and paratypes of the new species, as well as in the three specimens of L. novemlineata from Bolivia, examined by photographs, female holotype ( Figs 39–41 ) and two males ( Figs 42–45 ). Therefore, we think impossible to consider the differences as intraspecific variation.
