Ceratalictusinflexus sp. nov.

( Figs. 8 and 9 )

Diagnosis. Ceratalictus inflexus sp. nov. is distinguished from other Ceratalictus bythe combinationoflateralangle of pronotumobtuse; surface of mesoscutal diskweakly microreticulate; carinae of metapostnotum not reaching edge posteriorly; metapostnotum similar with metanotum in length and shape, and by the metasoma with blue reflections ( Figs. 8 and 9 ). The female has the basal elevation occupying all the longitudinal portion of labrum, the male has the antennae with sensilla placodea patches.

Variation. Most examined material is blue green but some specimens from Paraná and Espírito Santo are green. The blue reflections vary among specimens, including some violet reflections. The mesoscutum punctuation is sparser in some specimens.
