The Dynastinae (Coleoptera: Scarabaeidae) of the Bahamas with a description of a new species of \u3ci\u3eCyclocephala\u3c/i\u3e from Great Inagua Island

The seven genera and 13 species of dynastine scarabs recorded from the Bahamas are reviewed. Two of those species are endemic, including Cyclocephala dolichotarsa Ratcliffe and Cave, new species, described from Great Inagua Island. Eleven species are also known to occur in the USA and/or Cuba. Six species are probably not established based on infrequency of collection

Temperature-dependent development of the cycad aulacaspis scale, aulacaspis yasumatsui (Hemiptera: Diaspididae)

Egg duration period, immature development time, and pre-oviposition period of the cycad aulacaspis scale, Aulacaspis yasumatsui Takagi, were measured at 9 constant temperatures in the laboratory. Egg duration period ranged from 15 d at 20°C to 7 d at 30°C. First instar development time was 30 d at 18°C but only 4 d at 35°C. No first instars completed development below 18°C or above 35°C. Development time of second instar females ranged from 19 d at 18 and 20°C to 9 d at 30°C. Development time of male second instar + pupa ranged from 15 d at 20°C to 910 d at 2532°C. Pre-oviposition period averaged 14 d at 20°C to 8 d at 25 32°C; no females laid eggs at 18 and 35°C. The lowest temperature threshold for all stages ranged from 8 to 12°C and 538 degree-days were required for female immature development in a linear model. Development rates of the scale are compared to those of 3 of its natural enemies, Cybocephalus nipponicus Endrdy-Younga, Rhyzobius lophanthae (Blaisdell), and Coccobius fulvus (Compere and Annecke)

The Dynastine Scarab Beetles (Coleoptera: Scarabaeidae: Dynastinae) of Chile

The eight species of dynastine scarab beetles that occur in Chile are reviewed. Keys, descriptions, geographic distributions, monthly adult activity, notes on natural history, illustrations, and distribution maps are provided for all species. The erroneous records of 16 dynastine species reported from Chile are reviewed and clarified. The monotypic genus Chiliphileurus Endrödi, 1977 is reduced to junior synonymy with Eophileurus Arrow, 1908, and its only species, Chiliphileurus tuberculatus Endrödi, 1977, follows as a new junior synonym of the Asian Eophileurus cingalensis Arrow, 1908

Contribuciones de Zamorano al Entendimiento de la Biodiversidad de los Artrópodos de Honduras

The Zamorano Arthropod Collection was founded more than 30 years ago. It includes more than 250,000 specimens, with the dominant orders being Coleoptera, Hymenoptera, and Lepidoptera. Data of more than 90,000 of the identified insect specimens are digitized in a comprehensive database, and were collected in more than 300 sites, most within Honduras. The inventories of scarab and longhorn beetles, as well as of hymenopterous parasitoids, are of outstanding scientific value and unique in the region. Four influential projects, financed by external funds, were performed during the first 25 years of the collection´s existence, and are described with their main achievements: 1) inventory of the parasitoids of the sweetpotato whitefly, Bemisia tabaci (Gennadius); 2) diversity and biology of jewel scarab Chrysina spp. (Scarabaeidae); 3) inventory of the scarab beetle subfamily Dynastinae (Scarabaeidae); and 4) advanced capacity-building for teachers, nature reserve guards, and guides in various aspects of entomology. Often, support is provided in the way of coordination, logistics, and implementation for foreign entomological research projects in Honduras. Also, in cooperation with national foundations and governmental institutions, research on the arthropod biodiversity of protected areas in Honduras is conducted. For most of these, only fragmentary or no data still exist concerning the present arthropod fauna. During the coming years, the Zamorano Arthropod Collection will be united with another collection of outstanding regional importance, The Entomological Museum currently located in León, Nicaragua; this will add another 250,000 specimens, mainly collected in Nicaragua, to the Zamorano collection. Therefore, the Zamorano collection will house about 500,000 insect specimens and will evolve into the most comprehensive and representative arthropod collection of both Honduras and Nicaragua, becoming one of the largest and most important arthropod collections in Central America.

Más de 90,000 especímenes identificados están digitalizados en su propia base de datos y han sido recolectados en más de 300 sitios, la mayoría en Honduras. Los inventarios de escarabajos de las familias Cerambycidae y Scarabaeidae y de parasitoides himenópteros son de valor científico enorme y único en toda la región. Cuatro proyectos muy influyentes, financiados por fondos externos, fueron realizados durante los primeros 25 años de la colección y están descritos con sus logros centrales: 1) inventario de los parasitoides de la mosca blanca de la batata, Bemisia tabaci (Gennadius); 2) la diversidad y biología de los escarabajos joya, Chrysina spp. (Scarabaeidae); 3) inventario de la subfamilia Dynastinae (Scarabaeidae); y 4) la capacitación de maestros, guardarecursos y guías sobre varios aspectos de la entomología. Catorce estudiantes zamoranos hicieron sus tesis en biodiversidad vinculadas con la misión de la Colección. Zamorano apoya la organización, la logística y las investigaciones entomológicas internacionales en Honduras. Además, en cooperación con fundaciones e instituciones nacionales y estatales, se investiga la biodiversidad de artrópodos en áreas protegidas de Honduras. En la gran mayoría de estas áreas, pocos o ningún dato existe sobre la fauna de artrópodos presente. Próximamente, se unirá la Colección de Artrópodos de Zamorano con otra colección importante regionalmente, el Museo Entomológico de León, Nicaragua, añadiendo otros 250,000 especímenes, en su mayoría recolectados en Nicaragua, para ser incorporados al inventario presente. Así, la colección de Zamorano contará con aproximadamente 500,000 especímenes y se convertirá en la colección más grande y representativa de Honduras y Nicaragua, y será una de las colecciones más grandes e importantes de Centroamérica.DOI: http://dx.doi.org/10.5377/ceiba.v52i1.103

Sondeo biótico e inventario de los escarabajos dinastinos de Mesoamérica, Norteamérica y las Antillas: un proyecto multinacional a largo plazo

A Biotic Survey and Inventory of the Dynastine Scarab Beetles of Mesoamerica, North America, and the West Indies: a Long-term, Multi-country Project. Our long-term, multi-country inventory explores the diversity of the subfamily Dynastinae (Coleoptera: Scarabaeidae) in a megadiverse region seriously imperiled by deforestation, invasive species, and urbanization. The project’s objectives are (1) study and document the diversity, spatial and temporal distributions, and ecological preferences of dynastines north of South America, and clarify the nomenclature of the genera and species; (2) disseminate knowledge to the scientific community, students, and public through monographs and an electronic database; (3) train students, parataxonomists, and collection curators on taxonomy, biology, and identification of dynastines, and collection management; (4) develop synoptic collections of dynastines; and (5) provide educational opportunities for students and other groups not represented in science in the study area. Broad impacts encompass discovery, solidifying alliances for exploring biodiversity, enhancing investigative infrastructure by developing and disseminating databases, training students and technicians, increasing the ability to monitor habitats by using taxonomic knowledge, and establishing authoritatively identified collections.

Catalog and distribution atlas of the Scarabaeoidea (Insecta: Coleoptera) of El Salvador

Menos del 1% de la literatura sobre la biodiversidad de El Salvador es sobre invertebrados terrestres, lo que limita nuestro conocimiento de la diversidad, riqueza y distribución de este grupo en el territorio. Los Scarabaeoidea son megadiversos en múltiples ecosistemas y cumplen muchas funciones. Este trabajo tiene como objetivo catalogar los Scarabaeoidea en El Salvador. Se realizó una revisión exhaustiva de la literatura publicada y se revisaron numerosas colecciones entomológicas con material relevante. Se construyeron mapas para visualizar la distribución conocida de cada especie en el país. Existen 295 especies de escarabajos (incluyendo 19 nuevos registros en el país) representando 106 géneros en 7 familias en El Salvador. Se conocen seis especies precursoras. Veintidós especies se descartan como presentes en El Salvador, ya sea porque no son especies válidas o por identificaciones erróneas o registros dudosos. Este trabajo es la primera aproximación al conocimiento de los Scarabaeoidea en El Salvador, un territorio que usualmente se considera de nula importancia para la conservación de la biodiversidad regional debido a su reducida superficie, alta tasa de deforestación y sobrepoblación. Los resultados de este trabajo refuerzan la necesidad de realizar prospección biológica en el territorio para conocer, conservar y proteger la biodiversidad remanente. 2023 Universidad Nacional Autónoma de México.

Scarabaeoidea are megadiverse in multiple ecosystems and perform many functions. This work aims to catalog the Scarabaeoidea in El Salvador. We conducted an exhaustive review of published literature and reviewed numerous entomological collections with relevant material. Maps were constructed to visualize the known distribution of each species in the country. There are 295 scarab beetle species (including 19 new country records) representing 106 genera in 7 families in El Salvador. Six precinctive species are known. Twenty-Two species are discarded as occurring in El Salvador, either because they are not valid species or because of misidentifications or dubious records. This work is the first approach to knowing the Scarabaeoidea in El Salvador, a territory that is usually considered of no importance for the conservation of regional biodiversity due to its small area, high rate of deforestation, and overpopulation. The results of this work reinforce the need for biological prospecting in the territory to know, conserve, and protect the remaining biodiversity. © 2023 Universidad Nacional Autonoma de Mexico.
