ABSTRACT The earliest fossil member of Bothrideridae, Alveoderes yamamotoi Li & Cai gen. et sp. nov., is reported from mid-Cretaceous amber of northern Myanmar. Alveoderes gen. nov. appears to be ...most similar to extant Deretaphrus in the 3-segmented antennal club and pronotal morphology, but is also distinctive among the whole Bothrideridae in having a large cavity (possible glandular opening) at each anterior pronotal angle. Our discovery of a definitive bothriderid beetle from the late Mesozoic highlights the antiquity of the family. A key to the extant and extinct genera of Deretaphrini is added.
Los escarabajos joya (Coleoptera: Buprestidae) es una de las familias de escarabajos más diversas, sin embargo, en Colombia su diversidad no ha sido previamente estudiada. Este trabajo representa el ...primer análisis de la diversidad de la familia basada en una revisión bibliográfica para el país. Se registran cuatro subfamilias, catorce tribus, 30 géneros y 147 especies. De las 147 especies registradas, 100 no cuentan con datos específicos de localidad y 67 son especies endémicas. La región Caribe y la región Andina representan el mayor número de registros, siendo el departamento de Cundinamarca, el que cuenta con el mayor número de especies. En Colombia, el conocimiento de la familia es escaso comparado con países vecinos, en los cuales la familia ha sido muy estudiada durante los últimos años. A partir de esta primera revisión, Colombia se ubica como uno de los países con mayor diversidad de Buprestidae en la región.
Jewel beetles (Coleoptera: Buprestidae) represent one of the most diverse families of beetles. However, the diversity of the family has not been addressed in Colombia. This work represents the first analysis of the diversity of the family based on a bibliographic review of the country. As a result, a total of four subfamilies, fourteen tribes, 30 genera, and 147 species were recorded. Out of the 147 registered species, 100 do not have specific locality data, and 67 are endemic species. The Caribbean and Andean regions represent the highest number of records, with the department of Cundinamarca being the one with the highest number of species. In Colombia, knowledge of the family is scarce compared to neighboring countries, where the family has been widely studied in recent years. However, based on this first review, Colombia ranks as one of the most diverse countries in the region regarding Buprestidae.
This work presents the state of knowledge of the aquatic beetles from Colombia, with emphasis on species lists for 17 families recorded for the country, provided by Grupo Coleoptera de Colombia, and ...published by SiB-Colombia. Updated information on richness, diagnosis, habitat, and geographic distribution is provided for all families of aquatic beetles present in Colombia. Two hundred and forty-one species were recorded in 112 genera, which are considered true aquatic, false, or riparian beetles, according to their association with water bodies.
Este trabajo presenta el estado del conocimiento de los coleópteros acuáticos de Colombia, con énfasis en los listados de especies de 17 familias registradas en el territorio colombiano, los cuales han sido provistos por el Grupo Coleoptera de Colombia y publicados por el SiB-Colombia. Se aporta información actualizada de riqueza, diagnosis, hábitat y distribución geográfica de todas las familias de coleópteros acuáticos presentes en Colombia. Se registraron 241 especies en 112 géneros, los cuales son considerados como coleópteros acuáticos verdaderos, falsos o riparios según su asociación con los cuerpos de agua.
La larva de Parachrysina parapatrica Deloya y Morón, 1988 se describe por primera vez con base a especímenes procedentes del Valle de Tehuacán, localidad de Santa Ana, municipio de Teloxtoc, Puebla, ...México. Las larvas se recolectaron en raíces de amaranto (Amaranthus hipochondriacus L.) y se criaron hasta obtener pupas y adultos. Se incluyen ilustraciones de las estructuras de importancia taxonómica y comentarios sobre su biología.
The objectives of the present work were to determine the species of bats as floral visitors of Stenocereus huastecorum Alvarado-Sizzo, Arreola-Nava & Terrazas, 2018 in the Jaumave Valley, the night ...activity patterns of these floral visitors, their abundance within the flowering periods of 2018 and the comparison of effectiveness of nocturnal and diurnal pollinators. During March-May and August-October 2018, 12 nights were sampled per flowering period using three mist nets of 12 x 2.6 meters. Bats captured were identified, samples of pollen were taken from them which was processed by Erdtman's acetolysis. Three different treatments were applied to evaluate pollination effectiveness (nocturnal exclusion, diurnal exclusion, and control), selecting three flowers in 19 individuals. Leptonycteris yerbuenae (Martínez & Villa, 1940), L. nivalis (Saussure, 1860) and Choeronycteris mexicana (Tschudi, 1844) were the nocturnal floral visitors of S. huastecorum during its two flowering periods, the first species being the most frequently recorded throughout the night. Although this species has flowers with chiropterophilous characteristics, no significant differences were found in the effectiveness of diurnal, nocturnal and control pollinators. Very little is known about the nocturnal floral visitors of S. huastecorum and the effectiveness of its pollinators in the north of its distribution. Since this species is very important for the economy of rural communities due to the sale of its fruits, this research provides basic information for the conservation and use of this species.
Se registra al escarabajo acuático de dedos largos Postelichus musgravei (Hinton, 1935) (Coleoptera: Byrrhoidea: Dryopidae) para el estado de Nuevo León, México, siendo, el primer registro de la ...familia Dryopidae para este estado, así como el registro más norteño de esta especie. Además, se presenta un listado de especies de la familia Dryopidae de México y una clave de identificación para los géneros encontrados en Norteamérica continental.
