Togodolentus
Togodolentus is a genus of dirt-colored seed bugs in the family Rhyparochromidae, tribe Drymini. It was established by Barber in 1918. Species in this genus are small, ground-dwelling true bugs with cryptic coloration. The genus is part of the lygaeoid radiation of seed-feeding heteropterans.
Trapezonotus
dirt-colored seed bugs
Trapezonotus is a genus of dirt-colored seed bugs in the family Rhyparochromidae, established by Fieber in 1861. The genus comprises approximately 19-20 described species distributed primarily across Europe and parts of Asia. Taxonomic revision has clarified subspecies boundaries in some members, notably Trapezonotus dispar, which is divided into European and Caucasian-Asian Minor subspecies. The genus is part of the diverse lygaeoid assemblage of true bugs.
Trichocorixa kanza
water boatman
Trichocorixa kanza is a species of water boatman (family Corixidae) described by Sailer in 1948. It belongs to the genus Trichocorixa, a group of small aquatic true bugs characterized by hair-fringed hind legs adapted for swimming. The species has been documented in both North and Central America. Like other corixids, it inhabits freshwater environments where it swims upside-down near the water surface.
Trichopepla grossa
Trichopepla grossa is a species of stink bug in the family Pentatomidae, order Hemiptera. The genus Trichopepla is characterized by hairy or setose bodies, distinguishing it from many other pentatomid genera. Very limited information is available for this particular species, with only three observations recorded on iNaturalist. The species epithet "grossa" (Latin for "thick" or "coarse") likely refers to the robust body form or prominent setae typical of the genus.
Tyrannocoris
Tyrannocoris is a genus of stink bugs (Pentatomidae) established in 1992. The genus is characterized by predatory habits, distinguishing it from the primarily herbivorous majority of stink bugs. It is one of several predatory genera within the family. The genus has been documented in the Americas with limited but growing observational records.
Uhleriola
Uhleriola is a genus of dirt-colored seed bugs in the family Rhyparochromidae, containing a single described species, U. floralis. The genus was established by Horváth in 1908. Members of this genus belong to the diverse assemblage of true bugs commonly referred to as seed bugs or ground bugs.
Usingerella
Usingerella is a genus of plant bugs in the family Miridae, established by China & Carvalho in 1952. The genus contains at least two described species: Usingerella bakeri (Knight, 1943) and Usingerella simplex (Reuter, 1909). As a member of Miridae, it belongs to the diverse group of true bugs characterized by piercing-sucking mouthparts. The genus is poorly documented in literature, with limited information available beyond taxonomic descriptions.
Valtissius
Valtissius is a genus of dirt-colored seed bugs in the family Rhyparochromidae, established by Barber in 1918. The genus contains at least three described species. Members belong to the tribe Lethaeini within the subfamily Rhyparochrominae.
Vanduzeephylus falcatus
Vanduzeephylus falcatus is a species of plant bug in the family Miridae, first described by Van Duzee in 1917 under the basionym Reuteroscopus falcatus. The species belongs to a small genus of mirid bugs distributed in western North America. It is a true bug (Heteroptera) characterized by piercing-sucking mouthparts typical of the order Hemiptera.
Vazquezitocoris repletus
Vazquezitocoris repletus is a species of leaf-footed bug in the family Coreidae. The species was described by Van Duzee in 1925. It is known from the southwestern United States and Mexico.
Veliidae
riffle bugs, small water striders, broad-shouldered water striders, ripple bugs
Veliidae is a large family of predatory true bugs in the suborder Heteroptera, comprising approximately 1173 species across 66 genera. Members are small (1.5–6 mm), surface-dwelling insects that walk on water using surface tension and hydrophobic leg adaptations. They are distinguished from the related family Gerridae by their broader pronotum, smaller size, and internal genitalia differences. The family has a cosmopolitan distribution excluding Antarctica, with centers of origin in the Indo-Malayan region and the Caribbean.
Vesperocoris
Vesperocoris is a genus of plant bugs in the family Miridae. It belongs to the suborder Heteroptera within the order Hemiptera. The genus contains species that are part of the diverse mirid fauna, commonly known as capsid bugs or leaf bugs. Members of this genus are true bugs characterized by piercing-sucking mouthparts and hemelytra—forewings with leathery bases and membranous tips.
Weda tumidifrons
Weda tumidifrons is a species of stink bug in the family Pentatomidae, described by Barber and Sailer in 1953. It belongs to the genus Weda, a small group within the diverse stink bug fauna of North America. The species is poorly documented in scientific literature, with minimal published information on its biology and ecology. Records indicate it occurs in North America, though specific habitat preferences and life history remain largely unstudied.
Wheelerodemus
Wheelerodemus is a genus of true bugs in the family Blissidae, described by Henry and Sweet in 2015. The genus contains at least one described species, Wheelerodemus muhlenbergiae. Members of this genus are associated with grasses in the genus Muhlenbergia.
Xanthomelanodes
Xanthomelanodes is a genus of tachinid flies comprising 13 described species. As members of the subfamily Phasiinae and tribe Gymnosomatini, these flies are endoparasitoids of true bugs (Hemiptera: Heteroptera). Larvae develop inside their hosts and kill them. The genus was erected by Townsend in 1893 as a replacement name for Xanthomelana Wulp, 1892, which was already in use.
Xestocoris nitens
dirt-colored seed bug
Xestocoris nitens is a species of dirt-colored seed bug in the family Rhyparochromidae, tribe Lethaeini. It was described by Van Duzee in 1906. A lectotype was designated and redescribed in 2007, with new distributional records provided for the species. The species belongs to a genus of rhyparochromine bugs found in North America.
Xyonysius
false chinch bugs
Xyonysius is a genus of seed bugs in the family Lygaeidae, established by Ashlock & Lattin in 1963. The genus contains approximately eight to ten described species distributed primarily in the Americas. The most well-known member is Xyonysius californicus, commonly called the California false chinch bug, which is recognized as an agricultural pest. Species in this genus are small, elongate-oval true bugs with characteristic lygaeid morphology.
Zeridoneus
dirt-colored seed bugs
Zeridoneus is a genus of dirt-colored seed bugs in the family Rhyparochromidae, established by Barber in 1918. The genus contains three described species: Z. costalis, Z. knulli, and Z. petersoni. These true bugs belong to the tribe Myodochini within the subfamily Rhyparochrominae.
Zeropamera nigra
Zeropamera nigra is a species of seed bug in the family Rhyparochromidae, described by Barber in 1948. It belongs to the tribe Myodochini, a group of ground-dwelling seed bugs. Very little is known about its biology or ecology. Records indicate it occurs in the United States, though specific habitat associations and life history details remain undocumented.
Zicrona
Blue Bug (Z. caerulea)
Zicrona is a small genus of shield bugs (Pentatomidae: Asopinae) established by Amyot and Serville in 1843. The genus name derives from the Hebrew word זכרון (zicron), meaning "odorant." Four species are currently recognized, with Z. caerulea (Linnaeus, 1758) being the most widely distributed and commonly encountered. The genus is placed in the predatory subfamily Asopinae, though specific biological details for most species remain poorly documented.
