The description is supported by the morphology of all castes and COI barcoding. Both the morphological traits and COI sequence data indicate that the new species is closely related to Forel, 1910, a species restricted to the eastern Balkans and Anatolia. Furthermore, the little-known gyne of was redescribed based on a specimen collected in Bulgaria. The new data increases the number of species known from Bulgaria to nine, for which an updated key is provided.

The new species can be distinguished from other species of the genus by a combination of the following characteristics: snout-vent length 43.5-46.9 mm in males, females approximately two times size of males, head length greater than head width, nostril closer to tip of snout than to eye, tibiotarsal articulation reaching tip of snout when hindlimb stretched forward, relative lengths of fingers III > IV > I > II, dorsolateral fold absent, anterior dorsum green with evenly distributed small irregular shaped black blotches and posterior dorsum greyish brown with evenly distributed, large, irregular-shaped, black blotches, external vocal sacs present in adult males. In addition, the new species differs from its congeners by a genetic distance of 3.6%-14.2% in the mitochondrial 16S rRNA gene.

Knowledge about the identity and number of Mexican geometrids is limited, and particularly in regions of disproportionate Lepidoptera diversity such as Chiapas. This study provides the first comprehensive checklist of the ennomine moths from Chiapas, Mexico, a key region from the Mesoamerican biodiversity hotspot. Our checklist is derived from an exhaustive review of national and international scientific collections, digital databases, and intensive field work. A total of 239 taxa is documented: 227 named species in 101 genera, including 167 new state records and 12 unidentified taxa that likely represent undescribed entities. Representatives of 12 ennomine tribes are reported, Ennomini being the most diverse, followed by Odontoperini, Palyadini, Boarmiini, Caberini, and Macariini. The inclusion of a new combination for the genus is discussed based on comparative genital morphology. Our results add relevant regional faunistic information and help advance the knowledge of the geometrid fauna in Mexico, and ultimately provide a key step to understanding the biogeographical origin of this diverse moth group in the Mesoamerican biodiversity hotspot.

The new species is the first described from outside peninsular India and distributed north of the Indo-Gangetic Plains. . forms the deeply divergent sister taxon to Indian members of the complex with 15.7-18.1% uncorrected mitochondrial sequence divergence from them, and 21.0-28.5% from other . The new species is also recognised in tree-based delimitation methods and can be morphologically distinguished from other and species by a small body size (snout to vent length, SVL up to at least 45.5 mm), length of original tail < SVL, 16-18 rows of dorsal tubercles, 30-32 ventral scales across belly at midbody; dorsal colour pattern of four or five paired spots between neck and hindlimb insertions alternating with two or three much smaller paired spots. The divergence between . and Indian members of the complex is estimated to have occurred in the Middle Miocene, and it may be that tropical forest expansion during the Mid-Miocene Climatic Optimum allowed dispersal across the Indo-Gangetic Plains.

The region is subject to intense exploration for potential future deep-sea mining. One of the challenges associated with understanding potential impacts of extraction of these nodules is the insufficient knowledge of the CCZ fauna. In response to the need for improved taxonomic knowledge of the CCZ fauna, the International Seabed Authority (ISA) initiated the Sustainable Seabed Knowledge Initiative: One Thousand Reasons campaign, aiming to describe 1000 species new to science before the end of the decade. Within this call, a taxonomic workshop "New species of Amphipoda from the Clarion-Clipperton Zone" took place at the University of Lodz, Poland in February 2024, providing the impetus for the description of 24 new species of amphipods from the central Pacific abyss. This special issue is devoted to the publication of the new species from the workshop, and we summarise those findings here.
