Crossidius suturalis
Crossidius suturalis is a longhorn beetle species in the family Cerambycidae, described by John Lawrence LeConte in 1858. The species belongs to the tribe Trachyderini, a group of often brightly colored and flower-visiting cerambycids. Field observations indicate it is strongly associated with composite flowers (Asteraceae), particularly Isocoma tenuisecta, and shows sexual dimorphism in antennal length with males possessing longer antennae than females. Multiple subspecific taxa have been described across its range.
Paramiana n-sp-two
Paramiana n-sp-two is an undescribed species within the noctuid moth genus Paramiana, a group of medium-sized owlet moths in the tribe Xylenini. The genus Paramiana is native to western North America, with species distributed primarily in arid and semi-arid regions of the southwestern United States and Mexico. As an undescribed species, formal documentation is limited to specimen records and preliminary taxonomic notes. The species is recognized as distinct based on genitalic morphology and wing pattern characteristics that separate it from described congeners.
Tigrinestola tigrina
Tigrinestola tigrina is a species of longhorn beetle (Cerambycidae: Lamiinae) originally described by Skinner in 1905. The species has been collected from oak habitats in southeastern Arizona, specifically from dead branches of Quercus hypoleucoides (silverleaf oak). It is attracted to ultraviolet and mercury-vapor lights at night. The species occurs in the southwestern United States and Mexico, including Baja California.
