Revision of the Tribe Onciderini Thomson, 1860 (Coleoptera: Cerambycidae) from the Entomological Collection (CACH), Agronomic Sciences, Villaflores, Chiapas

: The present work was carried out in the Entomological Collection (CACH) located in the CUTT (University Center for Technology Transfer) San Ramón, property of the Faculty of Agronomic Sciences, Campus V of the Autonomous University of Chiapas; with the entomological material of the Onciderini Tribe (Cerambycidae: Lamiinae) in order to determine taxonomically at the genus and species level. Noting the collection data that each specimen presents as: place and date of collection and collector, which served to know its distribution and date of appearance in the state of Chiapas. The determination of the species that are reported in this work was carried out based on the specialized literature consulted and by comparison with photographic catalogs, where the external morphological characteristics of each species are described. 84 specimens of the Onciderini Tribe were reviewed, of which three genera Lochmaeocles , Oncideres and Tulcu s were determined, which group 19 species. The species with the highest number of specimens were: Lochmaeocles pseudovestitus , Oncideres ocellaris , L. cornuticeps pacificus , O. fulvostillata and O. putator putator with 13, 13, nine, six and six specimens respectively; the species Lochmaeocles marmoratus , Oncideres punctata , O. pallifasciata and O. rubra are only represented by one specimen respectively. The species Lochmaeocles cortuniceps cortuniceps , L. pseudovestitus , Oncideres albipilosa and Tulcus lycimnius are new records for Chiapas. Oncideres pallifasciata and O. rhodosticta are new records for Oaxaca. The species Lochmaeocles marmoratus and Oncideres sparsemaculatus are reported for the first time for Mexico.


Introduction
The knowledge of the specimens of an entomological collection is of vital importance to carry out studies of classification and taxonomic determination of species, at the same time a database is generated to reach an entomological collection of scientific reference. The Family Cerambycidae (Coleoptera) is one of the largest families of the Class Hexapoda, with distinctive and specific morphological characteristics of this group of insects. The specimens of the Onciderini Tribe (Coleoptera: Cerambycidae: Lamiinae) are morphologically characterized by having a body of moderate to large size, elongated, ovate, robust, subcylindrical, with colors ranging from reddish brown to black, more or less pubescent, the forewings (elitra) marked with rounded macules of variable colour, from pale yellow to ochraceous; specimens with white bands that vary in distinction are frequently found, and in some species these bands are reduced to a simple vestige, providing a characteristic aspect of each species [1].
In the first review of the Onciderini tribe made by Thomson in 1868; he described 13 new genera of the 28 he reports, which include the 151 recorded species. The second revision of this Tribe was carried out by Dillon & Dillon in the years 1945 and 1946 [1], who determined 65 genera, of which 33 of them were classified as new records, grouping 260 species, being the only important revision carried out to date. The 95.0% of the genera of the Onciderini tribe (77 of 81) are distributed and recorded for South American countries, of which 87.6% are found in Brazil (71 of 81) [2][3][4]. Although there are works related to this Onciderini Tribe, it is considered under the number of publications that make reference and emphasis, in its distribution and specific determination; In this sense, the present work was proposed with the objective of knowing the species of the Onciderini tribe specimens deposited in the Entomological Collection (CACH) of the Faculty of Agronomic Sciences, of the Autonomous University of Chiapas.

Materials and Method
The work was carried out with the entomological material of the Onciderini Tribe (Coleoptera: Cerambycidae: Lamiinae), which are dry and mounted on entomological pins and deposited in the Entomological Collection (CACH) of the Faculty of Agricultural Sciences, Campus V, of the Autonomous University of Chiapas; which come from collections made from 1984 to the present, which were captured by means of light traps and sporadic direct collections in the field in different locations in the state of Chiapas.
To carry out the taxonomic classification, each one of the specimens of the Lamiimae subfamily was separated at the Tribe, Genus and Species level, through morphological comparisons of the specialized literature for this subfamily; to determine the specimens at the species level, the works carried out by the researchers Dillon and Dillon, Noguera and Ailleo (1,5,6) were consulted, where they mention the external morphological characteristics of each species; and by comparison using the photographic catalogs made and published by Maes and collaborators, Martins and Galileo, and Bezark [7][8][9][10][11]. To observe the distinctive conspicuous morphological characters of each specimen, a Carl Zeiss brand electronic stereoscope was used. Once the species was determined, a total count of the specimens of each species existing in the entomological collection was carried out; In addition, the collection data for each of them was noted as follows: country, state, municipality, the latter written in bold, then the town, date of collection, and finally the name of the collector.
