Anthroleucosomatidae
Anthroleucosomatidae is a family of small to medium-sized millipedes in the order Chordeumatida, with approximately 19 genera and at least 40 described species. The family exhibits a core distribution centered on the Balkans and Caucasus region, extending eastward to Iran and central Siberia, with one highly disjunct North American species in Washington State. Many species are troglobionts (obligate cave-dwellers), including the world's deepest-occurring millipede, Heterocaucaseuma deprofundum, found below 2,000 meters in Krubera-Voronja Cave. The family shows exceptional diversity in the Caucasus, where 15 new genera and 36 new species were described in a single monograph.
Catopocerus
Catopocerus is a genus of small beetles in the family Leiodidae, subfamily Catopocerinae. These beetles are primarily subterranean or cave-dwelling, with reduced eyes and elongated appendages adapted to dark environments. The genus was established by Motschulsky in 1870 and contains species distributed across parts of North America and Eurasia. Members of this genus are among the most troglomorphic beetles in their family.
Geostiba
Geostiba is a genus of rove beetles (Coleoptera: Staphylinidae) in the subfamily Aleocharinae, tribe Geostibini. The genus contains over 250 described species distributed across Europe, Asia, North America, and Australia. Many species are placed in subgenera including Sibiota, Tropogastrosipalia, Sipalotricha, and Typhlusida. Species are predominantly found in temperate regions, with significant diversity in the Caucasus, Mediterranean, and Appalachian Mountains. Several species have been documented as predators of tick nymphs in soil ecosystems.
Leptusa
Leptusa is a genus of rove beetles in the family Staphylinidae, subfamily Aleocharinae. The genus was established by Kraatz in 1856 and currently comprises at least 20 described species globally. The Palaearctic fauna includes approximately 420 species and 74 subspecies distributed across 71 subgenera. Recent taxonomic work from the Georgian Caucasus has significantly expanded knowledge of the genus in that region.
Marinarozelotes barbatus
A ground-dwelling spider species in the family Gnaphosidae, first described by L. Koch in 1866. The first cytogenetic analysis of this species was conducted on specimens from Turkey, revealing a diploid chromosome number of 2n♂=22 with an X1X20 sex chromosome system. All chromosomes are telocentric, with X1 being the largest and X2 the smallest chromosome in the karyotype. Sex chromosomes exhibit positive heteropycnosis during prophase I of meiosis. The species has a broad native distribution across the Mediterranean to Caucasus region and has been introduced to the USA.
Plectrocnemia
tube maker caddisflies
Plectrocnemia is a genus of tube maker caddisflies in the family Polycentropodidae comprising more than 120 described species. Larvae are aquatic predators that construct silken capture nets to intercept prey. The genus has been extensively studied for its larval silk production, vibration-mediated predatory behavior, and population genetics. Species occur across Europe and into western Asia, with detailed biological information available for several well-studied species including P. conspersa and P. brevis.

A genus of springtails (Collembola: Symphypleona) in the family Arrhopalitidae. The genus was established by Vargovitsh in 2009. Multiple species have been described, including both epigean and troglobiont (cave-dwelling) forms. Some species exhibit troglomorphies including reduced pigmentation, elongated appendages, and modified foot complex.
