A New Brachypterous Species of Dichotomius Hope, 1838 (Coleoptera: Scarabaeidae: Scarabaeinae) from Bolivia
(The Coleopterists Society, 2024) Marcelo Amaya; Yannet Condori; Eunice Copa-Beltrán; Jorge Armando Arias-Buriticá; Fernando Zagury Vaz‐de‐Mello
A new brachypterous species of Dichotomius (Selenocopris) Burmeister, 1846 from Bolivia, Dichotomius abayoyensis Amaya, Condori, Copa-Beltrán, Arias-Buriticá, and Vaz-de-Mello, new species is described with diagnosis, photographs, and discussion of its taxonomic position in the genus. This new species is the eleventh known with the brachypterous condition in Dichotomius Hope, 1938. This species belongs to the Dichotomius geminatus (Arrow, 1913) species group and is related to Dichotomius vidaurrei Nunes and Vaz-de-Mello, 2013. Dichotomius abayoyensis differs from D. vidaurrei in having a longer cephalic process, pronotum with anterior excavation, pygidium with distinct punctures on the entire surface, parameres with a pronounced constriction on their distal lateral margins, subgenital plate present with sclerites without projection, and hind wing reduced with a row of dense setae on the superior margin. This species is known only from the “Chaparral de Abayoy” vegetation, located in Roboré (Chiquitos Province, Bolivia).

The growing public interest in biodiversity monitoring has led to a significant increase in initiatives that unite citizen scientists, researchers, and machine learning technologies. In this context, we introduce WildLIVE!, a dynamic biomonitoring and citizen science project. In WildLIVE!, participants analyze a vast array of images from a long-term camera trapping project in Bolivia to investigate the impacts of shifting environmental factors on wildlife. From 2020 to 2023, more than 850 participants registered for WildLIVE!, contributing nearly 9,000 hours of voluntary work. We explore the motivators and sentiments of participant engagement and discuss the key strategies that have contributed to the project’s initial success. The findings from a questionnaire highlight that the primary motivational factors for our participants are understanding and knowledge, as well as engagement and commitment. However, expressions of positive and negative sentiments can be found regarding involvement. Participants appeared to be driven primarily by a desire for intellectual growth and emotional fulfillment. Factors crucial to the success of this digital citizen science project include media exposure, creating emotional connections through virtual and in-person communication with participants, and visibility on public citizen science portals. Moreover, the project’s labeled dataset serves as a valuable resource for machine learning, aiding the development of a new platform that is compliant with the FAIR principles. WildLIVE! not only contributes to outcomes in science, society, and nature conservation, but also demonstrates the potential of creating a collaborative bridge between the general public, scientific research, biodiversity conservation, and advanced technological applications.
Habitat destruction threatens jaguars in a mixed land use region of eastern Bolivia

Large carnivores such as the jaguar (Panthera onca) are particularly susceptible to population decline and local extinction as a result of habitat loss. Here, we report on the long-term monitoring of a local jaguar population in a mixed land use area in the eastern lowlands of Bolivia from March 2017 to December 2019. We recorded 15 jaguar individuals and four reproduction events (five offspring from three females), suggesting that our study area harbors a resident breeding population. Seven iterations of spatially explicit capture-recapture models provided density estimates ranging from 1.32 to 3.57 jaguars per 100 km². Jaguar capture rates were highest in forested areas, with few to no jaguar captures occurring in pastures used for livestock. Massive deforestation after the survey period reduced the proportion of dense forest cover by 33%, shrinking the availability of suitable jaguar habitat and placing the resident jaguar population at risk. We use the jaguar as an indicator species to highlight the threat of habitat destruction in the Chiquitano region and to emphasize the importance of intact forest patches for jaguar conservation.
Historia natural del murciélago cara de perro del Mato Grosso Neoplatymops mattogrossensis (Vieira, 1942) (Chiroptera: Molossidae) en Bolivia

El murciélago cara de perro del Mato Grosso (Neoplatymops mattogrossensis), tiene hábitos muy pobremente conocidos. Presentamos datos sobre su historia natural (estructura poblacional, temperatura y humedad relativa en el interior y exterior de los refugios, dieta en base al análisis de muestras fecales) obtenidos en refugios de los predios de la Reserva Privada de Patrimonio Natural San Sebastián. Los refugios encontrados estuvieron habitados entre 1-10 individuos y en más del 70% de los refugios existe un solo macho adulto escrotal. Las temperaturas dentro de los refugios tienden a ser más estables que en el exterior, pero no así la humedad relativa. La dieta, esta está compuesta por Insecta, Arachnida, con los coleópteros como los más frecuentes seguido por Lepidoptera y Hemiptera.
