Idiogramma
Idiogramma is a genus of ichneumonid wasps and the sole extant genus in the tribe Idiogrammatini. The genus contains three described species: I. comstockii, I. elbakyanae, and I. euryops. It belongs to the subfamily Tryphoninae within the large parasitoid wasp family Ichneumonidae.
Nipus
Nipus is a genus of lady beetles in the family Coccinellidae, established by Casey in 1899. The genus comprises at least four described species distributed in North America: N. biplagiatus and N. niger (both described by Casey, 1899), and N. occiduus and N. planatus (both described by Gordon, 1970). These beetles are part of the diverse Coccinellidae family, which includes many species valued for predation on pest insects.
Protophotopsis
Protophotopsis is a genus of velvet ants (family Mutillidae) described by Schuster in 1947. The genus belongs to the diverse group of solitary wasps characterized by aposematic coloration and wingless females. As a member of Mutillidae, males are winged while females are wingless and often exhibit defensive behaviors including a powerful sting. The genus appears to be rarely encountered, with limited observational records available.
Synorthodes
Synorthodes is a genus of noctuid moths established by Franclemont in 1976. It contains three described species distributed in North America. The genus belongs to the tribe Eriopygini within the subfamily Noctuinae. Knowledge of this genus is limited due to its small size and rarity in collections.
Thornburghiella
Thornburghiella is a genus of moth flies in the family Psychodidae, established by Vaillant in 1982. It belongs to the tribe Pericomini and is characterized by specific morphological traits that distinguish it from related genera. The genus contains relatively few described species and is poorly represented in biological collections.
Usingerella simplex
Velvet-striped grasshopper
Usingerella simplex is a species of plant bug in the family Miridae, first described by Reuter in 1909 under the basionym Cyrtopeltis simplex. It is one of very few species in the genus Usingerella, a small and poorly documented mirid genus. The species is known from limited records in the southwestern United States, specifically Arizona and California. Available information on its biology and ecology is minimal.
Vesicephalus
Vesicephalus is a genus of globular springtails in the family Katiannidae, distinguished by a unique pair of interocular vesicles with demonstrated photoreception function. The genus is rare and has been recorded from North America, Spain, and Russia. The photoreceptive vesicles are thought to provide high sensitivity to light, potentially restricting these animals to dark microhabitats. At least four species are currently recognized.
Zagloba
Zagloba is a genus of lady beetles (Coccinellidae) established by Casey in 1899. The genus contains relatively few described species and is among the less commonly encountered coccinellid genera in North America. Members of this genus are small, dark-colored beetles with reduced or absent spotting patterns compared to more familiar lady beetles.
