03AC2D4B8863FFBFFF20FE42B3AB45CA.taxon	discussion	Remarks. Cobelura prenai sp. nov. is similar to C. stockwelli Corbett, 2004 (Figs 6 – 8), but differs as follows (males): scape distinctly, somewhat abruptly widened apically; central area of pronotum with sparse yellowishbrown pubescent maculae, and sides of this area with dense pubescent bands of same color; mesoventral process with sides convergent from base to posterior third and divergent in posterior third; metatibiae not arched. In C. stockwelli, the scape is slightly and gradually widened from base to apex; central area of pronotum with abundant yellowish-brown pubescent maculae, and sides of this area with fragmented band of same color; mesoventral process wider and with sides uniformly convergent from base to apex; and the metatibiae are arched.	en	Santos-Silva, Antonio, Devesa, Sergio (2021): New species and new records in American Acanthocinini (Coleoptera, Cerambycidae, Lamiinae).

03AC2D4B8860FFBEFF20FA86B27D4236.taxon	description	“ 7 (6). Scape dark brown on apical fifth; irregular maculae of yellowish-white (two behind upper eye lobes, other on pronotal disc), more or less confluent in two longitudinal bands on pronotum; elytra reddish-brown on basal half and dark brown on apical half. Panama (Canal Zone, Darien) ....................................................... C. stockwelli sp. nov. - Scape black; small yellowish-white pubescent maculae scattered on pronotal disc, not confluent in bands; elytra black. Peru (Junín) .................................................................... C. peruviana (Aurivillius, 1920). ” However, although Aurivillius (1920) did not indicate the color of the scape, it is possible to see that it is reddish brown with the apex blackish in a syntype male (Fig. 9). It is true that there are no distinct longitudinal pubescent bands on pronotum of the male syntype of C. peruviana, as well as that the elytra are entirely black. Nevertheless, it is possible that these features are variable in C. peruviana, as for example, the color of the femora, which may be dark or entirely reddish (Aurivillius 1920). Still according to Corbett (2004) (translated from Portuguese): “ Cobelura stockwelli is similar to C. peruviana and C. vermicularis by the pronotum and elytra with abundant small yellowish-white pubescent maculae, without whitish or brownish pubescent band … However, the maculae in C. stockwelli are larger and irregular, more or less confluent in two longitudinal bands on pronotum, and may be agglomerated or even fused on the lateral of the elytra (on median region or apical third) … In C. peruviana and C. vermicularis: maculae very small, well-distributed on pronotum and elytral surface. ” There is no difference between the size of the pubescent maculae in C. peruviana (syntype) and C. stockwelli. As Corbett (2004) affirmed that the pubescent maculae on elytra of C. stockwelli may be agglomerated or even fused on the lateral of the elytra, we can conclude that they may be as in the syntype of C. peruviana. In this case, the differences between C. stockwelli and C. peruviana become questionable. For now, it is not possible to affirm that they are or not the same species without examining a large number of specimens. According to Monné (1984) (translated from Portuguese): “ Antennae just surpass elytral apex. ” However, they distinctly surpass the elytral apex in the syntype male, and also in the male specimen illustrated by Monné (1984) (Fig. 10). According to the key from Monné & Monné (2017), C. stockwelli differs from C. peruviana by the scape black only apically in the former, and entirely black in the latter. This information does not agree with the syntype of C. peruviana (Fig. 9) and, apparently, nor with the specimen illustrated by Monné (1984) (Fig. 10).	en	Santos-Silva, Antonio, Devesa, Sergio (2021): New species and new records in American Acanthocinini (Coleoptera, Cerambycidae, Lamiinae).

03AC2D4B886BFFB1FF20FF2BB2EC4001.taxon	discussion	Remarks. Paranisopodus thalassinus sp. nov. is similar to P. peruanus Monné & Monné, 2007. According to Monné & Monné (2007), their species was described based on a single female from Peru (Cuzco) and the holotype was destroyed during the fire in 2018 at the MNRJ. According with the original description, P. viridis differs as follows: centrobasal elytral crest long and tuberculate dorsally; circular dark brown pubescent macula near middle of the elytra positioned in an obliquely descending band from apex of nearly black lateral macula to the center of the dorsal area; mesofemora almost entirely yellowish-brown, and metafemora with most of club yellowish-brown. In P. peruanus, elytra with subrounded centrobasal crest, with tubercles on top (translated from the original description), circular dark brown pubescent macula near middle of the elytra positioned in a slightly obliquely ascending band from the apex of the dark lateral macula to the center of the dorsal area, meso- and metafemora mostly dark brown (there is no information about the color of the legs in the original description, but the photographs of the holotype, show them entirely dark). Additionally, the scape in P. thalassinus is slightly widened from base to apex, while it is distinctly widened in the holotype of P. peruanus. In other species in which both sexes are known (e. g. P. heterotarsus Monné & Martins, 1976), the scape in male is narrower basally than in females. P. thalassinus differs from males of P. heterotarsus (see Nascimento & Santos-Silva 2019) especially by the distance between upper eye lobes about twice width of one upper lobe (larger than 2.5 times width of one upper lobe in P. heterotarsus), and metafemora not surpassing elytral apex (distinctly surpassing in P. heterotarsus). Paranisopodus thalassinus sp. nov. can be included in the alternative of couplet “ 5 ” from Monné & Monné (2017) modified: 5 (1).
