( Figs 1–13 View FIGURES 1–4 View FIGURES 5–8 View FIGURES 9–13 )

Description. Body 2.5–2.7 mm long and 2.1 mm wide (N=3). Body, except antennae and tibiae dark brown. Antennomeres I to IV brown, V to IX dark brown, X and XI yellowish. Tibiae brown. Antennal calli not separated from rest of head surface by grooves or sculpture, quadrate, punctured as vertex. Midfrontal sulcus distinct; supracallual and suprantennal sulci shallow; supraorbital sulci shallow reaching eye margin. Antenna short; antennomere I longest, almost length of antennomeres II and III together, slightly wider at apex; antennomere II rounded; antennomeres III to V longer than wide, decreasing in length; antennomere VI the smallest; antennomeres VI to X moniliform, densely pilose; antennomere XI with acute apex. Pronotum rectangular, 1.8 times wider than long. Elytra with first to third striae reaching elytral apex; fourth and fifth striae merging at medial third; sixth and seventh striae terminating at end of middle third; eighth stria reaching apex; ninth stria with deeper punctures at base becoming shallower to apex and terminating before apex ( Figs 1 View FIGURES 1–4 , 5 View FIGURES 5–8 ). Elytra with three small, rounded patches of white setae arranged as follows: one anterior between fourth and sixth striae, two medially between first and third striae and between sixth and eighth striae ( Fig. 1 View FIGURES 1–4 , 5 View FIGURES 5–8 ). Median lobe of aedeagus with lateral margins parallel and convergent to apex; internal sac of aedeagus with sparse pilosity and microsculpture ( Figs 9, 10 View FIGURES 9–13 ). Tignum with distal area wide, rectangular, basally sclerotized, with long setae on apical margin ( Fig. 13 View FIGURES 9–13 ). Vaginal palpi parallel, sides of each slightly divergent, with setae on apex; external margin on apical third slightly inflated, then oblique to rounded apex ( Fig. 12 View FIGURES 9–13 ). Bursa copulatrix membranous, without sclerites, except ring with small, sclerotized plicae proximally. Spermathecal receptacle oval, less sclerotized than pump and canal; pump longer than receptacle, with apical projection elongate and curved; canal deeply curved ( Fig. 11 View FIGURES 9–13 ).

Etymology. The specific epithet is an adjective (ethonym) to designate that it originated from the state of Bahia, Brazil, the state where the specimens were collected.
