Asyndetus
Asyndetus is a large genus of long-legged flies in the family Dolichopodidae, containing over 100 described species with worldwide distribution. The genus was established by Loew in 1869. Species occur across diverse biogeographic regions including the West Indies, the Palaearctic, and Scandinavia. Several species have been subject to taxonomic revision, with numerous synonymizations and transfers to other genera.
Phthiracarus
Phthiracarus is the second largest genus of ptyctimous mites (Euptyctima), with nearly cosmopolitan distribution. The genus belongs to the family Phthiracaridae within the oribatid mites (Oribatida), a diverse group of soil-dwelling arachnids. Species in this genus are primarily found in temperate forest soils and are associated with decomposition processes. Recent taxonomic work has described new species from previously understudied regions including Northeast China.
Sparganothoides
Sparganothoides is a New World genus of tortricid moths established in 1986, containing 32 described species. The genus exhibits greatest species diversity at middle elevations from central and southern Mexico through Costa Rica. A 2009 systematic revision organized species into six monophyletic groups based primarily on male genitalia morphology. Biological data remain limited, derived mainly from laboratory rearings of eight species.
Stephensia
Stephensia is a genus of moths in the family Elachistidae, a group of small, often inconspicuous microlepidoptera. The genus name has been used for multiple taxa across kingdoms, including a genus of fungi (Pyronemataceae) and historically as a synonym for a tachinid fly genus (Microsoma), but in entomological contexts refers primarily to the moth genus. The genus contains multiple described species distributed primarily in the Palearctic region.
Trigonometopus
Trigonometopus is a genus of true flies in the family Lauxaniidae, established by Macquart in 1835. The genus contains at least 25 described species. Lauxaniidae flies are generally small to medium-sized and often associated with decomposing plant material.
Valentibulla
Valentibulla is a genus of true fruit flies (Tephritidae) established by Foote & Blanc in 1959. The genus exhibits sexual dimorphism in which females are larger than males, but males possess enlarged forefemora used in mating. Male forefemur size predicts copulatory success. The genus is part of the diverse tephritid radiation, though detailed biological information remains limited.
