Comments. In the description of Panacris breviseta Lindner, 1964 , only P. tarsalis Gerstaecker, 1857 ( Lindner 1964: 8, as Spyridopa ) was mentioned. Lindner stated that P. breviseta has smaller ommatidia on the upper half compared to those of P. tarsalis . He did not compare his new species ( P. breviseta ) with P. nigribasis , a species of the same genus he had described 15 years earlier, from the same locality, also based on a male, not even mentioning it. We examined both holotypes ( Figs 17–25 ) and they are clearly conspecific, therefore we propose P. breviseta syn. nov. of P. nigribasis . They both have all legs completely dark brown and a bicolored wing, in which the basal third has a brownish membrane and veins and the apical two-thirds is yellowish pale. There is a third species, P. funebris James in James et al. 1980, originally described from Peru, based on a female, that might be conspecific with P. nigribasis . From the original description and the key provided by James et al. (1980), P. funebris , as seen in the other two here presented, has all legs dark brown and brownish markings at the base of the wing. However, as it is only known from females, which includes the holotype, is preferable to wait for an examination of the type before formalizing a new synonym.
