Type material. We examined the male holotype, from Brazil; and also the female holotype of Trachelia octolineata Audinet-Serville, 1834 , from Brazil ( BMNH).

Comments. Trachelissa pustulata is similar to T. maculicollis in having a shiny body surface, antennomere XII about half the length of III, and the elytra with fine sparse punctures. It differs from T. maculicollis by the prothorax subparallel at the sides, with a pair of antemedian tubercles that are evident or not, antennomeres IV–VI and VII–XI subequal in length, and tergite VIII with the apical margin obliquely truncate.

Geographical distribution. The species is reported for Brazil (Bahia to São Paulo) ( Monné, M.A., 2005). New state records from Brazil are added: Goiás and Mato Grosso ( Figs 157 , 158 ).
