In this study, we present the first draft genome assembly of Rowlandius potiguar, a cave-associated species endemic to karst systems of northeastern Brazil. Genomic DNA was sequenced using Illumina paired-end technology (2 × 150 bp), and reads were assembled using a de novo assembly pipeline. The resulting genome assembly has a total length of 1.8 Gb, distributed across 1,505,104 scaffolds and 1,510,944 contigs, indicating a highly fragmented assembly. The scaffold N50 and contig N50 values were both 3.2 kb, and the GC content was ...

New and interesting spiders (Arthropoda, Araneae) from Vashlovani National Park and Chachuna Managed Reserve (Georgia). Part II

Spiders collected individually during short outings at different locations, as well as during a trip to Vashlovani National Park and Chachuna Managed Reserve, were identified, resulting in the recognition of 22 species, of which three are described as new: Harpactea digitata Seropian, sp. nov. (♂, Dedoplistskaro) (Dysderidae), Leptopilos longiembolus Seropian & Japaridze, sp. nov. (♂, Vashlovani National Park), and Palpimanus obscurus Seropian & Bulbulashvili, sp. nov. (♂♀, Georgia, Azerbaijan, and Iran) (Palpimanidae). A female of Synema inexpectatum Seropian, Bulbulashvili, Makharadze & Baznikin, 2024, collected with several males, is described, while the species is recorded for the first time from the Kvemo Kartli region. Furthermore, Bogdocosa kronebergi (Andreeva, 1976), Marinarozelotes adriaticus (Caporiacco, 1951), and Pseudicius palaestinensis Strand, 1915 are recorded in Georgia for the first time. Diagnostic drawings and photographs of preserved specimens are included, along with detailed collecting data.
