| Summary: | Abstract The male of Campsurus barreirinhas sp. nov. is described and illustrated, representing the first records of Campsurus from Maranhão State, Northeast Brazil region. It is nearly related to C. litaninensis, both showing a unique genitalia, with the sternum IX extremely projected medially, pedestals bases distinctly separated in the middle, and pedestal rotated. The new species differentiates from C. litaninensis because the projection of IX sternum is rounded distally and the penes are stouter. This new species was collected along with Campsurus essequibo and Campsurus lucidus, representing the first records of these species in the Northeast Brazilian region. |
