Redescription. Dimension. BL: 1.96–2.60 mm; BW: 1.28–1.64 mm.

Body black. Elytra with dense white setae on 1st strial interval, in small patch at base of 3rd and 5th interstices, forming rounded patch occupying 2nd strial interval at its narrowest section until 4th strial interval on their broadest part on median region; small, shorter and horizontal strip on submedian region, which occupies part of 5th to 9th interstices, sometimes dense patch in 7th and/or 9th interstices ( Fig. 9 ). Pygidium with intermixed sparse white and golden setae; patch of dense white setae on median-basal region and moderately dense on latero-anterior corners ( Fig. 10 ). Median lobe of male genitalia with long, moderately curved and broad hinge sclerites; apical region without spicules; subapical region with long and short spicules denser in two irregular groups; submedian region with groups of spicules at apex of latero-basal lobes; latero-basal lobes of internal sac with spicules denser at apex; basal region with denticles denser near gonopore ( Fig. 11 ). Tegmen with lateral lobes separated by emargination about 0.7 times their length ( Fig. 12 ).

Material examined and detailed diagnosis. See Viana & Ribeiro-Costa (2013).

Diagnosis. Sennius bondari (subgroup 3) is externally similar to S. leucostauros and S. lojaensis by sharing horizontal strip of white setae on elytra, but the male genitalia pattern place this species in subgroup 3, along with S. leucostauros . Sennius bondari differs from S. leucostauros and S. lojaensis by the shape of the horizontal strip on elytra, the white setae pattern in pygidium and characters in male genitália.
