The cicadas (Hemiptera: Cicadidae) of Los Amigos Biostation, Peru with the description of a new species and three new records for Peru

ALLEN F. SANBORN — 2026-02-04

The cicadas (Hemiptera: Cicadidae) of Los Amigos Biostation, Peru are identified. Twenty-eight species representing 13 genera, three tribes, and two subfamilies were collected between August and December 2024. Guyalna protrudusa Sanborn sp. nov. is described along with the first female of Guyalna fasciata Sanborn, 2019. The first Peruvian records are provided for Ariasa bilaqueata (Uhler, 1903), Guyalna fasciata and Guyalna viridifemur (Walker, 1850). A list of the 28 cicada species currently known from Los Amigos Biostation is provided. The additions bring the total known Peruvian cicada diversity to 120 species.

Brazilian craneflies (Diptera: Tipulomorpha): the distribution and the challenges of a diverse group

DAUBIAN SANTOS — 2026-02-04

Craneflies in Brazil comprise 649 species. Despite this, they remain under-sampled and understudied, with a distribution record currently lacking. This study analyzed 1,626 individual records, revealing the species’ distribution. A total of 75.2% of these species are found exclusively in Brazil. Internal distribution patterns expose biases and gaps within the biomes, with the Atlantic Forest hosting 426 species, while the Caatinga and Pantanal each have just one. Only 2.8% of species are found across more than one biome, and the Atlantic Forest records the highest level of endemism (97%). Despite the diversity, craneflies require more attention, further research, improved databases, and better integration to achieve a comprehensive understanding of this diverse group.

**A new species of the genus Lathrobium Gravenhorst (Coleoptera: Staphylinidae) from Yakushima Island, southern Japan**

YUYA SATO — 2026-02-04

Lathrobium yakushimanum Sato, Hirai & Horiuchi sp. nov. of the L. brachypterum species group is described from Yakushima Island, Kagoshima Prefecture, Kyushu, Japan. This new species is easily distinguishable from other members of the L. brachypterum group with the internal sac of aedeagus with single sclerotized and slender part. For the Japanese species of the genus Lathrobium Gravenhorst, 1802, it is the first record from Yakushima Island and corresponds to the southernmost part of the distribution.
