This study aimed to determine the efficiency of four handmade traps with attractants for capturing Scolytinae in the "Laguna del Carpintero", Tampico, Tamaulipas. The traps were made with 1, 1.5, and 2.5 L PET bottles, placed 1.5 m from the ground and separated by 20 m. The attractants used were ethanol, methanol, ethanol + methanol, and apple cider vinegar + ethanol. For data analysis, a correspondence analysis was used to evaluate capture frequencies and treatments (trap type + attractant); in addition, a descriptive analysis was performed to calculate the total, minimum, maximum, and average number of individuals captured per species, as well as the capture percentage according to the trap and attractant design. A total of 408 specimens were collected, and four genera and 10 species of Scolytinae were identified, Hypothenemus, Coccotrypes, Microcorthylus, and Xyleborus; the first with seven species, while the other three with one species each. Hypothenemus birmanus (Eichhoff, 1878) with 237 specimens was the most abundant, on the contrary, Coccotrypes cyperi (Beeson, 1929) the least abundant with one specimen. Coccotrypes cyperi, Hypothenemus eruditus and Hypothenemus obscurus represent new records for Tamaulipas. Trap number 4 captured the highest number of individuals (200), while the capture frequency of each species was significantly associated with the treatments evaluated, the attractants ethanol + methanol and apple cider vinegar + ethanol were the most effective, with 109 and 123 captures, respectively. These results suggest that handmade traps represent an efficient alternative for collecting Scolytinae in mangrove ecosystems.

Based on the morphological study of specimens from the Maatawi Ecotouristic Park, five firefly species of the genus Photinus Laporte, 1833 were recognized, two of which are new to science: P. totiwi sp. nov. of nocturnal habits and its relationship with P. palaciosi (Zaragoza-Caballero, 2012) is discussed and P. ximutiwi sp. nov. of diurnal habits and is compared with P. badilloae Zaragoza-Caballero, 2017, P. ishwari Zaragoza-Caballero, 2017 and P. nayeliae Zaragoza-Caballero, 2017. To perpetuate the traditional knowledge of indigenous peoples, the scientific names were assigned in Bot’una language by the Matlatzinca community from San Francisco Oxtotilpan.

La hembra de la araña Curicaberis pedregal Rheims, 2015 (Sparassidae) es descrita por primera vez. La descripción está basada en dos hembras adultas del estado de Tlaxcala, México. La corroboración de la especie está basada en dos machos de la especie, recolectados junto con las hembras. Con estos nuevos registros, actualmente la especie está distribuida en Ciudad de México y Tlaxcala, estados del centro de México.

The genus Paraphetea Sakakibara and Creão-Duarte is reassigned to the tribe Polyglyptini based on the description of new morphological characters of adults and nymph that also represent new records from Colombia. As a result, the tribe Polyglyptini now comprises 89 species classified in 23 genera. Additionally, a key is provided for the genera of Polyglyptini morphologically related to Phormophora Stål (Aphetea Fowler, Dioclophara Kirkaldy, Paraphetea). The females and nymphs, as well as the biology of Paraphetea gibbula (Fairmaire), are described for the first time, including ant mutualism and maternal care. On the other hand, the biology of this species is compared with new natural history records of species from the tribe Thuridini, where Paraphetea was previously classified. In addition, the genitalia of males and females of P. gibbula and Thuris fenestratus Funkhouser are described. Thuris binodosus (Goding) is recorded in Colombia for the first time.

Se describe a Potosa pisaflores sp. nov. proveniente de material recolectado en la Cueva del Caracol, Pisaflores, Hidalgo, México. Esta es la cuarta especie del género y la segunda donde las hembras son conocidas. La especie nueva es similar a Potosa dybasi Goodnight & Goodnight, 1947, pero puede ser reconocida por el elevado número de tarsómeros de las patas II, así como por la forma general de los genitales masculinos.

Is described Anisostylatus elena gen. and sp. nov. based on revised material from the Colección Nacional de Insectos, UNAM (CNIN). This new genus presents all the diagnostic characters of the South American tribe Triboniini Roth, 1970, being the first representative of the tribe and the second genus of the subfamily Zetoborinae present in Mexico.

ABSTRACT. A study was conducted to determine which Coleoptera holotypes are primarily deposited at the National Museum of Costa Rica. To this end, a literature search and review were conducted on the publications for each species in the MNCR's Coleoptera holotype collection. Of the 471 holotypes currently present at the MNCR, the respective publications were found. Twenty-two specimens labeled as holotypes were also located, for which no publication has yet been found. Descriptions of 50 holotypes were found that were not deposited in the collection of the National Institute of Biodiversity or currently in the MNCR, despite one of these institutions being mentioned as a depository. The 471 holotypes belong to 27 Coleoptera families. This research aims to publicize the holotype species that are primarily in the MNCR collection and that have been published, as well as contribute to the return of holotypes that are not in the collection and that are important for biodiversity research in the Coleoptera order.

The fourth species of cockroach of the Neotropical genus Oulopteryx Hebard is described for Mexico, being the northernmost record of the genus. All the sclerites of the male genitalia are named by first time.

El estudio pr opone una nueva interpretación de las coronas de flores en los retratos de las monjas de la comunidad de santa Inés de Montepulciano, Bogotá. Esta particular manifestación pictórica surge en Colombia posiblemente en el siglo XVII y se extiende hasta el XIX. La evidencia material recuperada, con base en el estudio de 16 retratos de religiosas, apoyada en el empleo de técnicas de imágenes multiespectrales y de análisis instrumentales, sugiere varios momentos en la decoración de los adornos florales, especialmente, en las pinturas del siglo XVIII. La representación de las flores y su evolución estaría ligada al desarrollo del pensamiento científico en América y a la Expedición Botánica llevada a cabo en el Nuevo Reino de Granada. 

This ar ticle analyzes the work of the Franciscan Pedro de Alva y Astorga, a strong promoter of the cause of the Immaculate Conception in the 17th century; it focuses on the book Radii Solis and the engraving that accompanies it, since this provided the reference that inspired a canvas by Pedro López Calderón found in what was once northern New Spain. The article examines a dialogue that can be established between a Franciscan recognized for his staunch defense of the mystery of the Immaculate Conception, a little-known flamenco engraver, and an engraving that synthesizes the Immaculist thought of padre De Alva y Astorga. It also recalls the years spent in defense of his ideas and suffering constant harassment, and how this served as the basis for a painting signed in Mexico in 1731.
