B22687F3EC7DFF88FF5FF908FBBC4CC4.taxon	diagnosis	Diagnosis and comments. This group comprises 14 species, Sennius abbreviatus, S. bondari, S. durangensis, S. lawrencei, S. lebasi, S. leucostauros, S. lojaensis, S. medialis, S. nappi, S. rufomaculatus, S. transversesignatus, S. trinotaticollis, S. vivi sp. nov. and S. flinte sp. nov. (Table 1). It is based on the following characters of the male genitalia: internal sac trilobed (Fig. 7); dense rows of spicules on subapical region, usually short, forming a mass (Fig. 7, SMR); submedian region with two groups of large spicules (Fig. 7, SAR); latero-basal lobes with short spicules (Fig. 7, LAL). Johnson & Kingsolver (1973) defined the S. abbreviatus group and subgroups mainly based on the color of the integument, elytra pubescence and male genitalic characters. In this work, however, we allocated species to this group and its subgroups based only on characters of the male genitalia, especially the sclerites of the internal sac. Most species of the S. abbreviatus group have black elytra each with red-orange or brown maculae, but S. bondari, S. leucostauros and S. lojaensis have entirely black elytra and there are still other species that display intraspecific variation in color, from black with red-orange maculae to entirely black (S. nappi, S. lebasi and S. rufomaculatus).

Subgroup 1 includes S. abbreviatus, S. lawrencei, S. nappi, S. rufomaculatus, S. lojaensis, S. transversesignatus and S. vivi sp. nov., the last three are newly included. Species in this group are characterized by the male genitalia, which are similar among the included species, and the basic pattern of sclerites described for the S. abbreviatus group (Figs 7, 36, 73, 81, 61, 90, 106). This basic pattern is modified in the other seven species. Subgroup 2 comprises Sennius durangensis, S. medialis and S. flinte sp. nov., the latter species newly included. This subgroup is characterized by the male genitalia weakly sclerotized (Figs 19, 70, 27) and the latero-basal lobes of the internal sac narrower than in other species of the group. Subgroup 3 includes S. lebasi, S. leucostauros, S. trinotaticollis and S. bondari, the latter species newly included. All species in this subgroup lack the two large groups of spicules on the submedian region of the internal sac, and have spicules on the basal region, covering the lobes or forming more than two dense clusters (Figs 45, 53, 98, 11).	en	Viana, Jéssica Herzog, Ribeiro-Costa, Cibele Stramare (2013): Review of the largest species group of the New World seed beetle genus Sennius Bridwell (Coleoptera: Chrysomelidae), with host plant associations.

B22687F3EC7DFF88FF5FF908FBBC4CC4.taxon	biology_ecology	Biology. The most common way to collect adult Sennius is by rearing them from pods. Specimens have also been collected by flight intercept and Malaise traps. The species of the S. abbreviatus group are strongly associated with Senna Mill. (Family Fabaceae, subfamily Caesalpinioideae), where their larvae develop, consuming the seeds. One species, S. nappi, was found on flowers of Vochysia divergens Pohl, but this is not listed as a host plant since larvae have not been reared on the seeds of this plant. However, there are records of other hosts besides Senna. The following species have the greatest number of hosts plants (others genera besides Senna in parenthesis): S. rufomaculatus, 10 species (Amomum Roxb.); S. bondari, 14 species (Memora Miers); S. lebasi, 16 species (Acacia Mill. and Sebasnia Scop.) (Table 1). Different Bruchinae species may be found on the same plant (Viana & Ribeiro-Costa 2013). The following species are, as far as we know, associated with only one host plant: S. abbreviatus, S. lawrencei, S. lojaensis (with new host record), S. transversesignatus (with new host record) and S. durangensis, S. flinte sp. nov. and S. vivi sp. nov. (Table 1). The following host plant species have the greatest number of records of Sennius species from the S. abbreviatus group eating their seeds (each with five Sennius species recorded): S. obtusifolia and S. occidentalis (Table 2).

B22687F3EC79FF85FF5FFC83FD724B63.taxon	materials_examined	Material examined. Types: Bruchus abbreviatus Say, 1824. In the revision of Sennius, Johnson & Kingsolver (1973) indicated the type was lost. Bottimer (1968) synonymized Bruchus bivulneratus Horn, 1873 with Bruchus abbreviatus and Johnson, in the same year, designated a lectotype for Bruchus bivulneratus (Type locality: “ Southern and Western States ”) which is deposited in MCZ. This material was studied based on photos available in MCZ website and male genitalia illustrated in the revision of Johnson & Kingsolver (1973). Note: Until the publication of the work of Mawdsley (1993) it was believed the entire Say collection was lost, however this author recorded 56 species described by Say and deposited in MCZ.

B22687F3EC79FF85FF5FFC83FD724B63.taxon	diagnosis	Diagnosis. Sennius abbreviatus (subgroup 1) is externally similar to S. durangensis, S. medialis (subgroup 2) and S. rufomaculatus (subgroup 2) in having the pubescence regularly distributed on almost all elytra and the redorange maculae. Sennius abbreviatus differs by having most of the macula at the basal region of each elytron which in S. durangensis is more elongated occupying most of each elytron; in S. rufomaculatus the maculae are usually irregular; in S. medialis the maculae are more oval and smaller at the base and apex. Besides, S. abbreviatus differs in the distribution of pubescence on the dorsum, which is sparse in S. abbreviatus, and moderately dense in S. medialis; in the coloration of setae on the dorsum, which is white and brown in S. abbreviatus and only white or white and gold in S. durangensis; without dense patches on 3 rd and 5 th interstices in S. abbreviatus and present in S. rufomaculatus; and in the pubescence pattern on pygidium, which is homogeneous in S. abbreviatus and S. durangensis and denser basally in S. medialis and S. rufomaculatus. The male genitalia of S. abbreviatus is similar to that of S. rufomaculatus. Both species are placed in subgroup 1, but S. abbreviatus differs by the hinge sclerites with apex broader and slightly curved, and S. rufomaculatus with hinge sclerites broader at the base and strongly curved.	en	Viana, Jéssica Herzog, Ribeiro-Costa, Cibele Stramare (2013): Review of the largest species group of the New World seed beetle genus Sennius Bridwell (Coleoptera: Chrysomelidae), with host plant associations.

B22687F3EC76FF86FF5FFBBDFD5F4EA1.taxon	diagnosis	Diagnosis. Sennius durangensis (Subgroup 2) resembles S. medialis (Subgroup 2), S. abbreviatus (Subgroup 1) and S. rufomaculatus (Subgroup 1) by the extremely similar coloration of the dorsum. Sennius durangensis differs from the others only by having the elytra with sparse white or white and golden pubescence. In S. medialis the pubescence is moderately dense, not forming patches, which are present in S. rufomaculatus at the base of the 3 rd and 5 th interstices. And it differs by having the maculae more elongated, occupying most of each elytron, which in S. abbreviatus are smaller and occupy only the basal region. Comparing the genitalias, S. durangensis is more similar to S. medialis by having the median lobe slightly sclerotized, characteristic of subgroup 2, and differ from each other by the hinge sclerites, wider and bifid in S. durangensis, and thin with narrower base in S. medialis.

B22687F3EC74FF80FF5FF91CFB394A94.taxon	diagnosis	Diagnosis. Sennius flinte sp. nov. (subgroup 2) differs from all species of the S. abbreviatus group by the color of the integument and the pubescenceon the dorsum. The male genitalia of this species is most similar to that of S. durangensis (subgroup 2), by having hinge sclerites more elongated and almost straight. Both species can be separated mainly by the color of the elytra, which is entirely brown in Sennius flinte sp. nov. and black with pale macula in S. durangensis. The male genitalia of both species also differ in the groups of spicules on the subapical region and on the latero-basal lobes, which are denser in Sennius flinte sp. nov. than in S. durangensis.	en	Viana, Jéssica Herzog, Ribeiro-Costa, Cibele Stramare (2013): Review of the largest species group of the New World seed beetle genus Sennius Bridwell (Coleoptera: Chrysomelidae), with host plant associations.

B22687F3EC72FF83FF5FFD11FE6B4FAE.taxon	diagnosis	Diagnosis. The specimens of S. lawrencei with black elytra each with red-orange rounded macula superficially resembles S. rufomaculatus (subgroup 1). The male genitalia of S. lawrencei is more similar to S. rufomaculatus and S. nappi (both subgroup 1) however S. lawrencei differs externally from S. nappi by the lack of a horizontal stripe of white setae on the median basal region and from S. rufomaculatus by the lack of a white setal patch at the base of the interstices. The male genitalia in these three species are similar, but the internal sac of S. lawrencei lacks spicules in the apical region (present in S. rufomaculatus and S. nappi), the subapical region has one short group of spicules (two long group of spicules in S. rufomaculatus and three in S. nappi) and the submedian region has two elongated, lateral groups of long spicules (S. rufomaculatus with four, grouped in pairs, and S. nappi with three, two lateral and one medially).	en	Viana, Jéssica Herzog, Ribeiro-Costa, Cibele Stramare (2013): Review of the largest species group of the New World seed beetle genus Sennius Bridwell (Coleoptera: Chrysomelidae), with host plant associations.

B22687F3EC70FF9CFF5FFF7AFA8F4ACC.taxon	diagnosis	Diagnosis. Except for specimens with black elytra, this species is the only with a horizontal and red-orange macula on the submedian region. This macula extends to the outer margin of the elytra and, in general, occurs with another apical, irregular, red-orange macula, both in each elytron. Comparing the male genitalia, S. lebasi is more similar to species of subgroup 3, S. leucostauros, S. trinotaticollis and S. bondari. It differs mainly by the strongly curved and shorter hinge sclerites, in addition to the mass of spicules on the subapical region of the internal sac, which is more elongated and expanded, with the largest part being in the apical and subapical region.	en	Viana, Jéssica Herzog, Ribeiro-Costa, Cibele Stramare (2013): Review of the largest species group of the New World seed beetle genus Sennius Bridwell (Coleoptera: Chrysomelidae), with host plant associations.

Sennius lojaensis (subgroup 1) externally resembles S. bondari and S. leucostauros (subgroup 3) and specimens with black elytra of S. nappi (subgroup 1). All four species have a horizontal strip of white setae on the submedian region of the elytra. Sennius lojaensis differs from the other three by having a vertical strip of setae on the mid-apical region that reaches the submedian horizontal strip mentioned above. The male genitalia of S. lojaensis resembles that of S. nappi, however at the subapical region of the internal sac has larger dense groups of spicules similar to an open hand fan, whereas in S. nappi the spicules are aligned side by side.	en	Viana, Jéssica Herzog, Ribeiro-Costa, Cibele Stramare (2013): Review of the largest species group of the New World seed beetle genus Sennius Bridwell (Coleoptera: Chrysomelidae), with host plant associations.

B22687F3EC6BFF9AFF5FFA2AFA084B98.taxon	diagnosis	Diagnosis. Sennius medialis (subgroup 2) resembles externally S. abbreviatus (subgroup 1) and S. durangensis (subgroup 2). The similarities and differences between these species are mentioned under the " Diagnosis " of the respective species. The male genitalia of S. medialis and Sennius flinte sp. nov. are similar, corresponding to weakly sclerotized versions of the pattern found in the S. abbreviatus group. For this reason these two species are placed in subgroup 2. However, they are easily distinguished by their external morphology, mainly by the integument color of the elytra (black, each with macula, in S. medialis and red-orange in Sennius flinte sp. nov.).	en	Viana, Jéssica Herzog, Ribeiro-Costa, Cibele Stramare (2013): Review of the largest species group of the New World seed beetle genus Sennius Bridwell (Coleoptera: Chrysomelidae), with host plant associations.

B22687F3EC67FF97FF5FFCC0FA8C4D30.taxon	materials_examined	Material examined. Type: Bruchus rufomaculatus Motschulsky, 1874. Studying the types deposited at ZMUC, NHRS and ZMUM, Kingsolver (1979) synonymized Bruchus instabilis Sharp 1885 (Type locality: Guatemala) with B. rufomaculatus Motschulsky, 1874, however he did not specify in which museum was deposited the type of B. rufomaculatus. Followed the ZMUM website all V. Motschulsky types are deposited in their collection and probably the type of this species is there, but we have no answer from the curator of this museum until now. However B. instabilis was reviewed by Johnson & Kingsolver (1973) and based on this paper the species was recognized. Non-type (100): USA: Arizona: Nogales: 1, 11 / IV / [19] 71, Ehni (USNM).

B22687F3EC67FF97FF5FFCC0FA8C4D30.taxon	diagnosis	Diagnosis. Sennius rufomaculatus is a extremely variable species. According to Johnson & Kingsolver (1973) this species have a widespread distribution and the variation on the tegument color and pubescence “ is gradual over the range of this species, but similar specimens can be found in all parts of the range ”. Sennius rufomaculatus is similar to S. durangensis, S. medialis (both subgroup 2) and S. abbreviatus (subgroup 1) in the color of the pubescence and the presence of macula on the elytra. The difference between S. rufomaculatus and these species are discussed in the diagnosis of them. The few specimens of S. rufomaculatus that are completely black resemble specimens of S. leucostauros and S. bondari. However, they can be distinguished by the absence of white setae on the elytra forming a cross pattern in S. rufomaculatus.	en	Viana, Jéssica Herzog, Ribeiro-Costa, Cibele Stramare (2013): Review of the largest species group of the New World seed beetle genus Sennius Bridwell (Coleoptera: Chrysomelidae), with host plant associations.

B22687F3EC62FF92FF5FF9E8FB394C64.taxon	diagnosis	Diagnosis. Sennius vivi sp. nov. (subgroup 1) is easily distinguished from all other species of the S. abbreviatus group by the color and the pattern of pubescence on the dorsum. The male genitalia is most similar to S. nappi (subgroup 1) in having hinge sclerites long and narrow and a group of spicules on the subapical region of similar size. Sennius vivi sp. nov. differs by the two groups of spicules on the basal region of the internal sac, which is slightly dense, with few shorter spicules, while in S. nappi the spicules of this group are denser and longer.	en	Viana, Jéssica Herzog, Ribeiro-Costa, Cibele Stramare (2013): Review of the largest species group of the New World seed beetle genus Sennius Bridwell (Coleoptera: Chrysomelidae), with host plant associations.
