927A87C7FFA7F165FEDAFBAFFA8F5862.taxon	discussion	Remarks. – Among the genera of Tillomorphini without distinct upper eye lobes (Licracantha Lingafelter, 2011; Pentanodes Schaeffer, 1904; and Gourbeyrella Lane, 1959), Kerasellum gen. nov. is similar to Pentanodes, but differs as follows: elytra without eburneous or yellowish transverse band; centrobasal crest of elytra C-shaped; and apex of prosternal process slightly widened, making procoxal cavities slightly open. In Pentanodes, the elytra have eburneous or yellowish transverse band (except in P. albofasciatus Fisher, 1932, provisionally kept in the genus by Heffern et al. (2020 )), the centrobasal crest of elytra is longitudinal, from distinct to practically absent, and the apex of the prosternal process is strongly widened, making the procoxal cavities distinctly closed posteriorly. From Gourbeyrella, the new genus differs by the prothorax not subcylindrical (subcylindrical in Gourbeyrella), and elytra with C-shaped centrobasal crest (centrobasal crest absent in Gourbeyrella); and from Licracantha it differs by the antennomeres III-V without apical spine (present in Licracantha), elytra without eburneous or yellowish transverse band (present in Licracantha), and the centrobasal of elytra C-shaped (longitudinal and slightly tumid in Licracantha). Vitali (2011) transferred Eudereces elachys Martins & Galileo, 2013) to Tillomorphites Vitali, 2011. However, thisspecies has noupper eye lobes (Martins & Galileo 2013; one paratype male examined by us). The illustrations of the type species of the genus (Vitali 2011, 2017), T. robustus Vitali, 2011, and of T. otiliae Vitali, 2017 (see original description) clearly show that both species have distinct upper eye lobes. Therefore, we think thatthe transference of Euderces elachys to Tillomorphites was a mistake. A more detailed study will be necessary to correctly allocate Euderces elachys, which differs from Kerasellum by the absence of spine on the basal flagellomeres (present in Tillomorphiteselachys). On the tribal allocation of Kerasellum. – According to Martins (1975) (translated): “ The systematic of the subfamily Cerambycidae at tribal level is almost incomprehensible and, in the groups related to Tillomorphini (sensu Lacordaire, 1869), seems to me to be one of the most chaotic, needing urgently a broad-spectrum review. One of the main confusions arises from the genus Tillomorpha, type of Tillomorphini; the type species of Tillomorpha, T. lineoligera Blanchard (by monotypy and later designation by Thomson 1860: 229) [sic] deviates greatly from the tribal concept defined by Lacordaire (1869: 88); in this species, the procoxal cavities are widely open behind and the mesocoxal cavities are visibly open laterally. Now, Lacordaire himself states that the Tillomorphini are a dismemberment of the Clytini, separable by the closed mesocoxal cavities, but, “ il est, très-difficile de trouver une ligne de démarcation entre eux et ceux des groupes suivants (Cleomenini, Rhopalophorini, etc.) qui présentent le même caractère ” [it is very difficult to find a line of demarcation between them and those of the following groups [Cleomenini, Rhopalophorini, etc.] which present the same feature] (p. 88). ” More recently, Heffern et al. (2020), reported: “ The characteristics mentioned by diverse authors to separate Tillomorphini from Anaglyptini (and also Neocorini) appear not to be useful (see, for example, Lingafelter 2011). Thus, future studies to separate these tribes should be done. ” Whether the new genus belongs to Tillomorphini or Anaglyptini (or even another tribe) remains opened. However, based on the general appearance much more similar to genera currently included in Tillomorphini, we prefer to include the new genus in this tribe. Kerasellum afasciatum sp. nov.

927A87C7FFAAF169FED8FB05FADC5A59.taxon	discussion	Remarks. – The holotype was found in a large living branch that broke off and fell because of the galleries the beetled excavated, suggesting that this species develops in living wood, which is not uncommon among Trachyderini. Originally, the beetle was distinctly lemon yellow (Fig. 9 a), which is why we named the species “ citrinum, ” but the color faded over time.	en	Vlasak, Josef, Botero, Juan Pablo, Santos-Silva, Antonio, -, U.

927A87C7FFAFF16DFF6AFE13FE6A5899.taxon	etymology	Etymology. – The name “ zonatum ” (Latin, meaning banded) refers to the three color zones (brownish – yellowish – brownish) on the elytra.	en	Vlasak, Josef, Botero, Juan Pablo, Santos-Silva, Antonio, -, U.

927A87C7FFAFF16DFF6AFE13FE6A5899.taxon	discussion	Remarks. – Compsibidion zonatum sp. nov. is similar to C. achiraense Santos-Silva, Galileo & Wappes, 2017 (Fig. 26 - 29; see also photographs on Bezark (2025) and in Santos-Silva et al. (2017 )), but differs as follows: in females, distance between upper eye lobes wider, 0.36 times distance between outer margins of eyes (Fig. 30, 33); in females, distance between lower eye lobes 0.5 times distance between outer margins of eyes, making frons wider (Fig. 35); longitudinalcarinae between antennaltubercles almost absentin both sexes (Fig. 30, 33, 35); in females, narrowest area of mesoventral process distinctly wider than half mesocoxal width (Fig. 31, 34); central macula on elytra yellowish-brown in both sexes; and elytra at least partially yellowish-brown posteriorly in both sexes. In the holotype female of C. achiraense (the only known specimen), the distance between the upper eye lobes is shorter, 0.3 times the distance between the outer margins of the eyes (Fig. 26), the distance between the lower eye lobes is 0.41 times the distance between the outer margins of the eyes, making the frons narrower (Fig. 29), the longitudinal carinae between the upper eye lobes are wellmarked (Fig. 29), the narrowestarea of the mesoventralprocess is as wide as half the width of the mesocoxa (Fig. 27), central macula on elytra is yellowish white, and the elytra are entirely dark brown posteriorly. Additionally, the three specimensof Compsibidion zonatum examined have the first vertical row of the upper eye lobes with two ommatidia, while in there are three ommatidia in holotype female of C. achiraensis. However, this feature may eventually be variable. The new species is also similar to C. amboroense Santos-Silva, Galileo & Wappes, 2017 (see also photographs on Bezark (2025) and in Santos-Silva et al. (2017 )), but differs especially by the elytra with more abundant, long and erect setae (very sparse in C. amboroense), yellowish-brown macula on center of elytra reaching the suture (not reaching in C. amboroense), inner area of the upper eye lobes narrower, with two ommatidia (wider, with three / four ommatidia in C. amboroense), and the widest area of the upper eye lobes with three ommatidia (five in C. amboroense).	en	Vlasak, Josef, Botero, Juan Pablo, Santos-Silva, Antonio, -, U.
