Paratypes: 1 female, same data as holotype, deposited in IBSP 163515; 1 male from Pau Brasil (Fazenda São João) [15 ° 27 ʹ 50 ʺS, 39 ° 39 ʹ0 3 ʺW] Bahia, Brazil, 06.I. 1971, CEPLAC, deposited in MNRJ 13127; 1 male from Jussari (Fazenda Santo Antonio) [15 ° 11 ʹ 27 ʺS, 39 ° 29 ʹ 42 ʺW], Bahia, Brazil, 05.VIII. 1970, CEPLAC, deposited in IBSP 85329; 1 male from Jussari (Fazenda Santo Antônio) [15 ° 11 ʹ 27 ʺS, 39 ° 29 ʹ 42 ʺW], Bahia, Brazil, 9.VII. 1970, CEPLAC, deposited in MNRJ 13052; 1 male from Jussari [15 ° 11 ʹ 27 ʺS, 39 ° 29 ʹ 42 ʺW], Bahia, Brazil, 5.VIII. 1970, CEPLAC, deposited in IBSP 5176; 1 female from Camacan (Fazenda Esperança) [15 ° 25 ʹ0 8 ʺS, 39 ° 29 ʹ 45 ʺW], Bahia, Brazil, 7.VI. 1969, CEPLAC, deposited in IBSP 163252.

Additional material examined. BRAZIL: Bahia. Jussari [15 ° 11 ʹ 27 ʺS, 39 ° 29 ʹ 42 ʺW], Fazenda Ribeirão do Antonio, 1 male, 11.IV. 1997, CEPLAC (MNRJ 13310); Fazenda Bethânia, 1 female, 17.V. 1971, CEPLAC (MNRJ 13129).

Etymology. “ Aberém  ” is a typical meal of the Bahia culinary tradition and also plays a role in the religious ritual of Candomblé. It is made with macerated corn or rice and cooked in banana leaves.

Diagnosis. Males of Celaetycheus aberem  sp. nov. ( Figs 6 A –BView FIGURE 6. A – D) resemble those of C. mungunza  sp. nov. ( Figs 12 A –BView FIGURE 12. A – D) by the large embolus, absence of a tegular projection and a median apophysis curved prolaterally at tip, but can be distinguished by the larger median apophysis ( Fig. 6 AView FIGURE 6. A – D). Females of C. aberem  sp. nov. ( Figs 6 C –DView FIGURE 6. A – D) can be distinguished from the remaining species of the genus by the subquadrangular shape of the median sector of the epigynum ( Fig. 6 CView FIGURE 6. A – D).
