Additional material examined. BRAZIL: Bahia. Ilhéus [14°47ʹ20ʺS, 39°02ʹ56ʺW], CEPLAC, 6 males, 18 females, 6 immatures, 7.IV.1998 (IBSP 19133, 19276, 19255, 19309, 19315, 19319, 19351, 19353, 19368, 19374, 19378, 19427, 19426, 19434, 19435); 8 males, 9 females, 5 immatures, 11.IV.1998 (IBSP 19108, 19130, 19141, 19162, 19170, 19199, 19232, 19334, 19341); 2 males, 2 females, 5 immatures, 12.IV.1998 (IBSP 19042, 19090, 19180); all collected by A.D.

Etymology. “ Moqueca ” is a typical meal of the Bahia culinary tradition. It made with fish or seafood braised with different spices, coconut milk and “dendê”palm oil.

Diagnosis. Males of Celaetycheus moqueca sp. nov. ( Figs 11A–B ) can be distinguished from the remaining species of the genus by the large median apophysis and elongated additional tegular projection on the palp. Females of C. moqueca sp. nov. ( Figs 11C–D ) resemble those of C. flavostriatus ( Fig. 1A ) by the subtriangular shape of the median sector of epigynum, but can be distinguished by the absence of lateral lobes from the lateral fields of the epigynum.
