7A1987D6FFC51024B06EFE397D82F954.taxon	discussion	Remarks The new species is differentiated from the other two species in Apagomerella by the presence of dense light-yellow pubescence on the ventrites; the different pattern of light denser pubescence on the pronotum, on the lateral region and post-mid portion centrally in the new species, only on the lateral region in A. dissimilis, and on the mid-anterior portion and along mid longitudinal band in A. versicolor; and the absence of light dense pubescence on the elytron along lateral margin, apex, and elytral suture. The new species is herein assigned to Apagomerella because of the following shared characters with its congeneric species: lower ocular lobe longer than anterior portion of the gena in frontal view (not examined in A. dissimilis); antennomere III filiform, subequal or with similar length to scape and antennomere IV; prothorax without lateral projections; elytron without carinae, with elytral apex rounded; and tarsal claws with inner teeth shorter than outer teeth (not examined in A. dissimilis). Apagomerella dissimilis is known from Costa Rica, while A. versicolor is distributed in the Brazilian Southeast and South regions, Argentina, and Paraguay (Tavakilian & Chevillotte 2024). Hence, the new species represents the first record of Apagomerella for the Brazilian Northeast Region (Fig. 2). Comments on the genus Gilmour (1962) described Apagomerella briefly, based only on male specimens of A. suturella (= A. versicolor), pointing out the scape longer than antennomere III and mesotibia sulcate dorsally. The latter character is in fact absent in A. versicolor, which presents only a dense pubescent coverage on the outer face of mesotibia. This is also the case for the new species. The mesotibial sulcus is a common feature in many groups of Lamiinae (e. g., Acanthoderini and Onciderini), but it is absent in Hemilophini (Lacordaire 1872; Martins & Galileo 2014 a). The mesotibial sulcus usually is surrounded by a dense coverage of setae, then, possibly for this reason, Gilmour (1962) misinterpreted this character in Apagomerella. Martins & Galileo (2014 a) redescribed the genus mentioning, among other characteristics, the antenna reaching the elytral apex in the antennomere IX in females, scape subequal to antennomere III and IV individually in length, antennomere XI about half of antennomere X in length, prothorax wider anteriorly than the “ base ” [posterior margin], and ventral surface of the body without coverage of dense pubescence [free translation from Portuguese]. Apparently, Martins & Galileo (2014 a) based their redescription only on A. versicolor, since this character set does not properly represent A. dissimilis, the other species of the genus. In A. dissimilis, the antenna almost reaches the elytral apex in females (as in the new species), the anterior margin of the prothorax is a little narrower than the posterior margin, and the ventral surface of the body is partially covered by dense pubescence (on the mesoventral sclerites) (Galileo & Martins 2005). Besides, antennomere XI is subequal or just a little shorter than antennomere X in all the species of the genus. The new species resembles some fireflies (Lampyridae) in its coloration pattern, as do the other two species of the genus (see photos in Bezark 2025). This similarity in the coloration pattern with Lampyridae is also observed in many genera of Hemilophini (e. g., Hemilophus Audinet-Serville, 1835 and Pyrobolus Chevrolat, 1838), indicating potential mimicry associations among these groups (Linsley 1961; Nascimento et al. 2010), although there have been no fieldwork studies focused on this topic.	en	Júnior, José Osvaldo Silva, Souza, Diego de Santana, Machado, Renato José Pires, Iannuzzi, Luciana (2025): New species and new records of flat-faced longhorned beetles (Cerambycidae, Lamiinae) from the Brazilian Northeast Region.

7A1987D6FFC91020B048FBC17F26F8BA.taxon	discussion	Remarks The new species is diagnosed by the following character set: distinct elytral coloration pattern, apical fusion of the two dorsal elytral striae, and the strongly depressed area in the metaventrite. The new species shares with its congeneric species the shape of the scape, slightly curved on the inner face basally, and antennomere III very elongated, more than twice as long as antennomere IV, with fringes of dense black setae on its inner face. A pair of dorsal striae on the elytron is also present in other species of Malacoscylus (e. g., M. cirratus and M. xanthotaenius), but the fusion of these striae apically was never previously described in the genus. This type of fusion of dorsal striae or carina in Hemilophini is also present in Acabanga Martins & Galileo, 1991 and Lycidola Thomson, 1864. Malacoscylus is known from South America, with species distributed in the Amazon or Atlantic Forest. In Brazil, four species are known from the Southeast and South regions (Tavakilian & Chevillotte 2024). Hence, the new species represents the first record of Malacoscylus for the Brazilian Northeast Region (Fig. 2). Comments on the genus Malacoscylus has some similar genera in Hemilophini, as defined by Martins & Galileo (1991 a), where they discussed the differences with Tyrinthia Bates, 1886, and described two related genera to comprise species classified in Malacoscylus at that time: Lamacoscylus Martins & Galileo, 1991 and Sybaguasu Martins & Galileo, 1991. Although this and other works (Martins & Galileo 1991 b, 2014 b; Galileo & Martins 1998) focusing on these genera are useful to separate each other and their species, they rely upon a series of shared characters, e. g., frons with projections in the males (some species of Malacoscylus, Sybaguasu, and Tyrinthia), scape curved basally (Malacoscylus and Sybaguasu), fringes of dense setae on the inner face of antennomeres III or III – IV (Malacoscylus and Tyrinthia), presence of conspicuous dorsal striae on the elytron (forming a dorsal carina in some species of Lamacoscylus), and body length short in general (Martins & Galileo 1991 a, 2014 b). There are so far no phylogenetic studies on these genera, and possibly at least part of them are paraphyletic or polyphyletic. We hope for future phylogenetic and revision works focused on these genera to better understand the relationships among them and the classification of their species. In Malacoscylus, many species present a coloration pattern similar to net-winged beetles (Lycidae) (e. g., M. cirratus and M. auricomus), varying between dark and yellow shades, especially noticeable in the pronotum and elytron, besides the presence of distinct elytral striae (Linsley 1961). The new species also presents this coloration pattern. Besides, apparently, some species are similar to fireflies (Lampyridae) in their coloration pattern (e. g., M. fasciatus, M. nearnsi, and M. xanthotaenius) (see photos in Bezark 2025).	en	Júnior, José Osvaldo Silva, Souza, Diego de Santana, Machado, Renato José Pires, Iannuzzi, Luciana (2025): New species and new records of flat-faced longhorned beetles (Cerambycidae, Lamiinae) from the Brazilian Northeast Region.
