  • Agabetes

    Agabetes is a small genus of diving beetles (family Dytiscidae) in the subfamily Laccophilinae. The genus contains two described species: Agabetes acuductus, described from North America in 1828, and Agabetes svetlanae, described from the Palearctic region in 1989. The genus is the type genus of the tribe Agabetini. Members are aquatic beetles inhabiting freshwater environments.

  • Alaocybites

    A genus of small, eyeless or microphthalmic weevils in the family Raymondionymidae. Originally described from California with two eyeless species, the genus was later discovered in the Russian Far East (Primorsky Kray) and represented by a fossil in Alaska. The genus is characterized by reduced or absent eyes and the absence of tarsomere IV on all legs, traits associated with edaphic (soil-dwelling) habits.

  • Anterastria

    A small genus of noctuid moths established by Japanese lepidopterist Shigero Sugi in 1982. The genus comprises two disjunct species with remarkably different geographic ranges: one Palearctic species distributed across south-eastern Siberia, Korea, and Japan, and one Nearctic species found in Tennessee, United States.

  • Tipulomorpha

    crane flies, crane flies and allies

    Tipulomorpha is an infraorder of Nematocera containing crane flies and allied families, representing one of the largest and most diverse groups of true flies. The infraorder comprises five extant families: Tipulidae (large crane flies), Limoniidae (limoniid crane flies), Pediciidae (hairy-eyed crane flies), Cylindrotomidae (long-bodied crane flies), and Trichoceridae (winter crane flies). With approximately 15,000 described species in the family Tipulidae alone, this group exhibits remarkable morphological diversity, particularly in larval forms. Adults are characterized by elongated bodies, extremely long legs, and single pair of membranous wings. Larval habitats range from aquatic environments to terrestrial soils, decaying wood, and even snow-covered surfaces in specialized groups.
