Redescription
Dimension. Length (Pronotum-elytra) 1.96–2.60 mm. Width 1.28–1.64 mm.
Integument colour. Black body (Figure 3A), except labrum, maxillary and labial palps dark brown to black (Figure 3C). Antennae orange-red, some specimens with seven apical segments dark brown (Figure 3B). Legs light to dark brown (Figure 3B).
Pubescence. Head with dense tuft of white pubescence posterior to the postocular lobe (Figure 3C). Ocular sinus, postocular lobe and mandibles with white pubescence moderately dense. Labrum with scattered golden pubescence, denser at the apex (Figure 3C). Pronotum with intermixed white and golden pubescence, moderately white pubescence distributed in small tufts in lateral third and at midline of basal lobe (Figure 3A). Scutellum with dense white pubescence (Figure 3A). Elytron with white, golden and black intermixed pubescence, white pubescence densely distributed as follows: in a continuous line at first striae interval, in small tufts at bases of the third and fifth striae intervals; wide semicircular macula almost covering the base and apex of second striae interval at its smaller width, and reaching its greatest width over middle of fifth striae interval; in small, short and transversal band in the submedian region that covers part of the sixth to ninth striae interval, sometimes dense tuft in seventh and / or ninth striae interval (Figure 3A). Pygidium with intermixed sparse white and golden pubescence; macula of dense white pubescence in the median-basal region and moderately dense in the lateroanterior corners (Figure 3D). Ventral surface with white pubescence denser at base of mesepimeron, posterior margin of metepisternum, distal region of hind coxa, and at base of first abdominal ventrite (Figure 3B).
Head with coarse punctuation, except median line of frons with fine punctuation; labrum smooth, frons convex, frontal carina and transverse sulcus absent; ocular sinus deep, more than half an eye length (Figure 3C). First and third antenna segments filiform, second and fourth moniliform, fifth to tenth wider than long, and eleventh globular with pointed apex (Figure 3B). Pronotum moderately convex (Figure 3B); disc with basal lobe not sulcate (Figure 3A). Scutellum subquadrate, slightly wider than long (Figure 3A). Fourth striae of elytron with denticle at base (Figure 3E). Hind femur with a prominent tooth (0.01–0.06 mm) on ventral margin slightly microserrate (Figure 3F). Hind tibia with lateroventral carina extending half its length (Figure 3G), lateral, dorsomesal and ventral carinae long, ending near coronal denticles (Figure 3F, G); mucro about 1.8 times longer than the opposite coronal denticle (Figure 3F, G). Last abdominal ventrite of male emarginate at middle, rounded in female. Pygidium not concealed by elytra, lateral margins slightly curved, with rounded apex in males, more acuminate in females (Figure 3B, D).
Male genitalia. Median lobe about 5.2 times longer than the width at its middle, expanded at apex; ventral valve with convex lateral margins and truncate apex; hinge sclerites long and wide, with external margin moderately concave and sinuous (Figure 3H – HS). Internal sac trilobate, basal region without spines (Figure 3H – BR), submedian region (Figure 3H – SMR) with small spicules in two irregular dense clusters; subapical region (Figure 3H – SAR) with lateral clusters of large spicules not aligned at bases of lateral lobes; apexes of lateral lobes with minute spicules; apical region (Figure 3H – AR) of middle lobe with denticles near the gonopore sclerite (Figure 3H). Tegmen with lateral lobes separated by deep emargination, about 0.7 times the length of lateral lobes (Figure 3I).
Type material
It was possible to compare the type deposited in BMNH only by photos. Labels: “ Type ” “ Brazil | Bahia | 1928 | Dr. G. Bondar. | 1233 [right vertical label]” “Pres. by | Imp. Bur. Ent. | Brit. Mus. | 1928-504” “[unreadable]” “ Bruchus | bondari | n sp.” Note: In the original description, Pic (1929) did not mention the number of specimens studied, however, the information on labels of the photographed material correspond to those described in that work, therefore this is probably type material.

Host plants
Fabaceae: Caesalpinioideae: Senna pistaciifolia, S. pendula, S. occidentalis, S. bicapsularis, S. macranthera, S. multijuga, S. surattensis, S. splendida, S. alata.
New record. Fabaceae: Caesalpinioideae: Senna neglecta var. oligophylla, S. neglecta var. neglecta, S. appendiculata (= S. australis).
Note: Koller and Nunes (2006) found a few specimens of S. bondari in seed capsules of Memora peregrina (Bignoniaceae), however, it is unclear whether the larvae really consume its seeds. Hence, because of the scarce information of Koller and Nunes (2006) and the unusual Bignoniaceae as a host of Sennius, we will not consider it as a record for S. bondari until more information is added.
Discussion
Sennius bondari differs from Sennius nappi mainly by black integument of elytron with white pubescence forming a semicircle at the midline, and a dense tuft of white pubescence on basal half of pygidium. Belongs to the abbreviatus group of Sennius established by Johnson and Kingsolver (1973) that has three subgroups: subgroup 1, with Sennius abbreviatus (Say 1824) and Sennius rufomaculatus (Motschoulsky 1874); subgroup 2 with Sennius medialis (Sharp, 1885) and Sennius durangensis Johnson and Kingsolver 1973; subgroup 3, with Sennius lebasi (Fähraeus 1839), Sennius leucostaurus Johnson and Kingsolver 1973, and Sennius trinotaticollis (Pic 1930). It shares with these species the same male genitalia pattern, with internal sac trilobate, submedian region with small spicules, and large lateral clusters of spicules not aligned in subapical region at base of lateral lobes. Sennius bondari is more similar to the species of subgroup 3, in particular to Sennius leucostauros by sharing with it a horizontal band of white pubescence on elytra, and hinge sclerites of middle lobe larger than those seen in the other species of the subgroup. Sennius bondari has elytra with sparse golden pubescence and pygidium with dense macula of white pubescence in median basal region not extending to apex, whereas in Sennius leucostauros the golden pubescence is denser at the first and second striae intervals, pygidium with dense white pubescence on median side extending to apex. In male genitalia, Sennius bondari has hinge sclerites wider than those of Sennius leucostauros, and the internal sac of Sennius bondari has clusters with large spicules aligned in the subapical region, as in Sennius leucostauros they are absent.
