In this issue of the journal Dugesiana, we pay a well-deserved tribute to Dr. Rodolfo Novelo Gutiérrez, a passionate researcher of Odonata from the Instituto de Ecología, A.C. in Xalapa, Veracruz

Richness and edaphic diversity in a subdeciduous medium forest: a study on the Maya Train route

2025-05-11T13:09:38-06:00

A study was conducted to evaluate the impact of the Maya Train construction on edaphic biodiversity. For this purpose, several collections were made in 2024, during the months of June and July, at the end of the dry season and the beginning of the rainy season. A total of 28 leaf litter samples and 28 soil samples were collected. The leaf litter samples were processed using Berlese funnels, while the soil samples were analyzed to determine moisture content using the gravimetric method.
The Shannon & Wiener diversity index, the Simpson dominance index, and Pielou's equitability index were calculated to assess edaphic biodiversity. A list of mites and springtails species found in the study area is presented and compared with similar studies conducted in well-preserved sites in the Yucatán Peninsula.
Finally, the loss of edaphic biodiversity associated with vegetation clearing and soil erosion was analyzed based on the data obtained in the study.

A new species of 𝑆𝑡𝑒𝑛𝑜𝑡𝑎𝑟𝑠𝑢𝑠 Perty (Coleoptera: Endomychidae: Endomychinae) from Costa Rica, with the establishment of a new species group

2025-06-25T10:04:37-06:00

Stenotarsus is a mainly pantropical genus with nearly 270 species described. Here we describe a new species from Puntarenas, Costa Rica, belonging to the newly defined and diagnosed Stenotarsus spiropenis species group. The new species is diagnosed, described in detail an illustrated. The species of the S. spiropenis species group show characteristics that are unique among Neotropical species of the genus.

𝐷𝑖𝑝𝑙𝑜𝑡𝑎𝑥𝑖𝑠 𝑟𝑜𝑑𝑜𝑙𝑓𝑜𝑛𝑜𝑣𝑒𝑙𝑜𝑖, a new Mexican species from Hidalgo state (Coleoptera: Scarabaeidae: Melolonthinae), with a new definition of the Puberula species group.

2025-06-11T20:11:25-06:00

𝐷𝑖𝑝𝑙𝑜𝑡𝑎𝑥𝑖𝑠 𝑟𝑜𝑑𝑜𝑙𝑓𝑜𝑛𝑜𝑣𝑒𝑙𝑜𝑖 sp. nov. is described and illustrated from arid region of southern of state of Hidalgo, Mexico. This species is related with the species of the Puberula species group of this genus, group newly defined with different composition of species as previously known, adding to 𝐷. 𝑔𝑢𝑎𝑡𝑒𝑚𝑎𝑙𝑖𝑐𝑎 Moser, 𝐷. 𝑟𝑢𝑔𝑜𝑠𝑖𝑓𝑟𝑜𝑛𝑠 Moser, 𝐷. 𝑠𝑞𝑢𝑎𝑚𝑖𝑠𝑒𝑡𝑖𝑠 Delgado & Capistrán and this new species, including all these species within a new key. A checklist of the Puberula species group is provided, including data on distribution, seasonality, and known elevational range, along with distribution maps for each species.

The “helicopter damselflies” of Mexico (Odonata: Coenagrionidae: Pseudostigmatinae): Diversity, distribution and natural history

2025-06-18T18:50:43-06:00

The “helicopter damselflies” comprise a group of zygopterans characterized by their large size and with unique life history traits. Current molecular studies of the suborder Zygoptera place them as a subfamily within the large group of Coenagrionidae. Mexico hosts three of the six recognized genera of helicopter damselflies in America: Mecistogaster, Megaloprepus and Pseudostigma. Among its members some of the largest odonates in the world are included. Most species occur in humid tropical forests (including montane mesophytic forest), with the exception of Mecistogaster ornata Rambur, 1842 which has colonized and apparently successfully adapted to both humid and dry tropical forests. As far as is known, the naiads of these species are exclusive phytotelmata inhabitants, living in bromeliads, bamboo nodes and in water stored at tree holes. Some of its species are considered indicators of tropical forest disturbance in the Americas.

Notes on the diversity, current distribution and natural history of Mexican helicopter damselflies are presented with a key to separate the species of the group.

Ants (Formicidae: Hymenoptera) associated with caves in Mexico: distribution and checklist

2025-06-24T18:40:56-06:00

Formicids have a relevant ecological role within cave ecosystems, harboring a great diversity that has not been fully recorded and represented. Therefore, presenting an annotated list of the formicidae associated with caves in Mexico is an important contribution to the understanding of their relationship with cave environments. The present list comprises a total of 562 individuals belong to 32 genera from 9 subfamilies were recorded, with 60 species and 20 morphospecies. The species recorded are distributed among 23 caves in 9 states of the country. New records are also presented in the distribution of species in some states of the country and 48 of the 60 mentionen species are new records for caves.There are two new records to Mexico: Hylomyrma dentiloba (Santschi, 1931) and Carebara ca. pilosa. This is the most comprehensive effort at the date in order to synthesize knowledge of ants in cave environments in Mexico.

2025-05-15T18:27:11-06:00

We present two cases of teratology in 𝐻𝑒𝑙𝑖𝑐ℎ𝑢𝑠 𝑠𝑢𝑡𝑢𝑟𝑎𝑙𝑖𝑠 LeConte, 1852 and a compilation of teratological records for aquatic Coleoptera.

The genus 𝑃𝑠𝑖𝑙𝑜𝑐𝑙𝑎𝑑𝑢𝑠 Blanchard, 1845 (Coleoptera: Lampyridae: Psilocladinae) in Mexico

2025-05-15T18:22:38-06:00

Almost a century and a half since the description and record of 𝑃𝑠𝑖𝑙𝑜𝑐𝑙𝑎𝑑𝑢𝑠 𝑠𝑡𝑜𝑙𝑎𝑡𝑢𝑠 (Gorham, 1881) in Mexico, three new species of 𝑃𝑠𝑖𝑙𝑜𝑐𝑙𝑎𝑑𝑢𝑠 Blanchard, 1845 are described: 𝑃. 𝑎𝑧𝑡𝑒𝑐𝑢𝑠 sp. nov. from San Luis Potosí and Tamaulipas, 𝑃. 𝑐𝑎𝑛𝑐𝑖𝑛𝑜𝑖 sp. nov. from Chiapas and 𝑃. 𝑛𝑜𝑣𝑒𝑙𝑜𝑖 sp. nov. from Hidalgo. In addition, a distribution map and an identification key are provided.

Two new lampyrid (Coleoptera) species from Santuario de Niebla, Xalapa, Veracruz, México

2025-06-23T13:09:00-06:00

Two new species of fireflies are described from the Bosque de Niebla Sanctuary, Veracruz, Mexico: 𝐴𝑜𝑟𝑝ℎ𝑎𝑙𝑙𝑢𝑠 𝑛𝑜𝑣𝑒𝑙𝑜𝑖 sp. nov and 𝑃ℎ𝑜𝑡𝑖𝑛𝑢𝑠 𝑟𝑖𝑐𝑎𝑟𝑑𝑎𝑒 sp. nov. 𝐴𝑜𝑟𝑝ℎ𝑎𝑙𝑙𝑢𝑠 𝑛𝑜𝑣𝑒𝑙𝑜𝑖 sp. nov. differs from the only other species of the genus by its larger size, coloration and morphological characteristics present in the clype and elytra, thus extending the known distribution of the genus 𝐴𝑜𝑟𝑝ℎ𝑎𝑙𝑙𝑢𝑠. 𝑃ℎ𝑜𝑡𝑖𝑛𝑢𝑠 𝑟𝑖𝑐𝑎𝑟𝑑𝑎𝑒 sp. nov. is distinguished from 𝑃ℎ𝑜𝑡𝑖𝑛𝑢𝑠 𝑎𝑙𝑑𝑟𝑒𝑡𝑒𝑖 by its larger size and the morphology of its aedeagus. With this new record, the genus 𝑃ℎ𝑜𝑡𝑖𝑛𝑢𝑠 in Veracruz amounts to 43 species, highlighting the importance of the state for the diversity of this genus in Mexico.
