INTRODUCTION
The family Cerambycidae is one of the largest of Coleoptera with about 40,000 described species (Tavakilian & Chevillotte, 2022).Historically, Brazil is one of the countries with more specialists and with the Cerambycidae fauna best studied.Despite that, there are still many new species to be described, and many new geographical records and taxonomical notes to be published.
Recently, we studied a large quantity of specimens collected by the junior author and collaborators as part of a national survey of wood-boring beetles, the "Nationwide survey of Brazilian bark and ambrosia beetles (Coleoptera, Curculionidae, Scolytinae and Platypodinae)", and that belongs to MEFEIS (see acronym below).This allowed us to find interesting geographical and taxonomical results.
Herein, we describe a new Acanthocinini species (Lepturges (L.)) from the state of Goiás (Brazil), propose a new synonymy in Piezocera (Piezocerini), and register new geographical records of 18 species belonging to three subfamilies (Cerambycinae, Lamiinae, Lepturinae) and 15 tribes.Additionally, the only Piezocera key available is updated.

Material
All specimens from Venezuela and Colombia that were examined have the apex of the antennal tubercles distinctly acute (somewhat spiniform).The specimen from Brazil has the apex of the antennal tubercles flattened.However, as no other morphological differences were found, we believe that this is just an extreme variation.In the same way, the specimen from Brazil has a very distinct longitudinal pale-yellow band on the curvature of the elytra (Fig. 1C).The specimens from Venezuela and the two males from Colombia (Figs. 1F-1H) do not even have a trace of that band.However, the other male from Colombia has that band slightly distinct.Therefore, we believe that the presence of that band is another feature variable in the species.
Remarks: According to Martins (1976) on Piezocera flavipennis (translated): "Absence of a demarcated anterior pronotal sulcus separates flavipennis from the unicolorous species examined above, where this sulcus is visible;" and in the key, "Pronotum without trace of anterior longitudinal sulcus …, " leading to P. flavipennis.Still according to Martins (1976), he examined the holotype.The holotype belonged to the MNRJ and was destroyed in a fire.Posteriorly, Martins (2003) repeated the same information about the pronotal shape of Piezocera flavipennis.However, this information does not correspond to the shape of the anterior area of the pronotum of this species.Zajciw (1970) reported (translated): "Prothorax narrow … in the middle of the anterior area with a longitudinal groove resembling that of Piezocera nodicollis Melz., 1934 …" In fact, it is possible to see the distinct sulcus in the photograph of the holotype taken by Steven W. Lingafelter (Fig. 11).
Remarks: Comparing a paralectotype male of P. monochroa (Figs.2D-2E) with specimens identified as P. serraticollis, from Mexico and the USA (Figs. 2F-2G), we could not find any morphological difference.Furthermore, the current geographical distribution of both species is overlapped in the Mexican state of Chiapas, reinforcing the indication that the two names correspond to the same species.
Martins (1976) reported about P. serraticollis (translated): "The redescription given below is restricted to topotypic specimens.Other specimens, in some cases intermediate between serraticollis and monochroa, are discussed in the item variations.Only the examination of very abundant material from Mexico and Central America will be able to elucidate the status of this species;" "Three specimens from Almolonga, Veracruz, Mexico (BMNH, MNHN) were included by Bates (1885: 258) in the type series of Piezocera monochroa; it seems to me that they actually belong to serraticollis.They are different from topotypic specimens: elytra apex with less prolonged lateral projection; erect setae on dorsal surface almost the same length as the scape." This later affirmation contradicts one of the differences between P. serraticollis and P. monochroa pointed out by him: erect dorsal setae shorter than length of the scape in P. serraticollis, and longer than the scape in P. monochroa.Furthermore, the elytral apex is variable in other species of the genus, which makes it evident that the same also occurs in P. monochroa.To reinforce that the differences pointed out by Martins (1976) are just specific variations, it is interesting to translate another part of his comments on variations in P. serraticollis: "Specimen from Salina Cruz, Oaxaca, Mexico: erect dorsal setae very elongated; spicule of the prothorax distinct; erect setae very abundant on entire body…" The number of erect setae was a feature used by him to separate P. serraticollis from P. monochroa in the key: erect setae more abundant in the latter than in the former.Another feature used in the key by Martins (1976) was the sexual punctation on the abdomen: present in males of P. serraticollis; absent in males of P. monochroa.However, in the redescription of P. monochroa, he reported that perhaps they are absent in males of this species.Therefore, based on this evidence of intraspecific morphological variation, P. serraticollis is synonymized with P. monochroa.

Pronotum    Monné (1993) listed the species as Tilloglomus spectabilis, a condition kept until today.However, as indicated in the original description, the correct is T. spectabile, because "glomus" (Latin) is neuter gender.
