However, there is a single female specimen from the locality of Parque Nacional de Sete Cidades, Piauí state( Fig. 23(indicated by a question mark)), which could possibly belong to this species. This locality is approximately 400 kmaway in a straight line northeast of the typelocality of  C. brachylobus. Through morphological comparison we discarded the possibility of this female belonging to any of the other three species of  Cerozodus, being most similar to  C. brachylobus. However, only the male holotypespecimen was available for study, and the pruinosity of the thorax and abdomen is partially masked by greasing in this specimen. Additionally, this female is slightly smaller in body size and has the colour of legs slightly darker. This kind of intraspecific variation was also observed in other  Cerozodusspeciesand in the paratypeof  C. brachylobus( Vieira et al. 2013). Consequently, the hypothesis of this female belonging to a new species must be taken into account. Since we could not confidently assign it to  C. brachylobus, we decided to suggest that the existence of this female specimen is an incentive to further collections in the same locality to gather more specimens and solve this case. The label data on this specimen is: “ Brasil, Piauí, [Parque Nacional de] Sete Cidades [ 04°05′59″S 41°42′50″W], Malaise Bananeira, 07–13.ii.2013(  1 ♀ INPA)”.   Variation.Male paratypewith postocular setae black; mesonotum golden to brown pruinose; mid and hind femora dark brown; body length 14.6 mmand wing length 9.5 mm. Paratypenot examined in this study, information is based on Vieira et al.
