Length. Body: 14.4 mm; wing: 9.6 mm.

Holotype condition. Right postpedicel ( Figs 1C View FIGURE 1 , 2E View FIGURE 2 ) and right mid leg missing ( Fig. 1A View FIGURE 1 ); abdomen glued between T4 and 5 ( Fig. 2F–G View FIGURE 2 ); right wing detached and mounted on microslide ( Fig. 2C View FIGURE 2 ); terminalia placed in microvial with glycerin and pinned with the specimen.

Female. Unknown. However, there is a single female specimen from the locality of Parque Nacional de Sete Cidades, Piauí state ( Fig. 23 View FIGURE 23 (indicated by a question mark)), which could possibly belong to this species. This locality is approximately 400 km away in a straight line northeast of the type locality 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 holotype specimen 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 Cerozodus species and in the paratype of 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 paratype with postocular setae black; mesonotum golden to brown pruinose; mid and hind femora dark brown; body length 14.6 mm and wing length 9.5 mm. Paratype not examined in this study, information is based on Vieira et al. (2013).
