Plaumannimyia
Plaumannimyia is a genus of fruit flies in the family Tephritidae, established by Hering in 1938. The genus contains three described species distributed in Mexico, Guatemala, and Brazil. As members of Tephritidae, these flies likely exhibit the characteristic wing patterning and body form typical of the family, though specific morphological details for the genus remain poorly documented in available literature.
Plinthocoelium suaveolens plicatum
Bumelia Borer
Plinthocoelium suaveolens plicatum is the western subspecies of a striking longhorned beetle distributed from Texas west to New Mexico, Arizona, and northern Mexico. Distinguished from the nominate eastern subspecies by bronze or cupreous tints and weak transverse rugae on the pronotum, this beetle exhibits brilliant iridescent green coloration with contrasting orange and black legs. Larvae develop in the roots of living Sideroxylon lanuginosum (gum bumelia), with adults active during summer months. The subspecies intergrades with P. s. suaveolens in northeastern Texas.
Plionoma rubens
Plionoma rubens is a species of longhorned beetle in the family Cerambycidae, described by Thomas L. Casey in 1891. It belongs to the tribe Trachyderini, a group known for bright coloration, diurnal activity, and attraction to flowers. The species occurs in the southwestern United States and northern Mexico, with records from Texas west to California. Like other members of its genus, adults are associated with mesquite and other woody legumes.
Poecilocapsus nigriger
Poecilocapsus nigriger is a plant bug species in the family Miridae, native to North and Central America. It is closely related to the fourlined plant bug (Poecilocapsus lineatus), a well-documented pest of ornamental plants and vegetables. As a member of the Hemiptera, it possesses piercing-sucking mouthparts used to extract plant fluids. Specific ecological details for P. nigriger remain sparse in published literature, with most research attention focused on its congener P. lineatus.
Poecilotettix
Poecilotettix is a genus of spur-throated grasshoppers in the family Acrididae, tribe Dactylotini. The genus contains two described species: Poecilotettix pantherinus (panther-spotted grasshopper) and Poecilotettix sanguineus (red-lined grasshopper). Members of this genus are distributed in the southwestern United States and Mexico.
Pogonodaptus
Pogonodaptus is a genus of ground beetles in the family Carabidae, tribe Stenolophini. The genus was established by G. Horn in 1881 and contains two described species: Pogonodaptus mexicanus (Bates, 1878) and Pogonodaptus rostratus Darlington, 1935. Members of this genus occur in the Neotropical region.
Pogonomyrmex tenuispinus
Pogonomyrmex tenuispinus is a species of harvester ant in the genus Pogonomyrmex. Like other members of this genus, it is a seed-collecting ant native to arid regions. The species was described by Auguste Forel in 1914. As a harvester ant, it likely participates in seed dispersal and ecosystem engineering through nest construction, though specific ecological studies for this species are limited.

negundo
Poliaenus negundo is a species of longhorn beetle in the family Cerambycidae, first described by Schaeffer in 1905. The species is known from Mexico and the United States. As a member of the subfamily Lamiinae and tribe Pogonocherini, it belongs to a group of beetles commonly associated with woody plants. Information regarding its biology, host associations, and specific habitat requirements remains limited in published literature.
Polpochila capitata
Polpochila capitata is a species of ground beetle in the family Carabidae. It was originally described as Melanotus capitatus by Chaudoir in 1852 and later transferred to the genus Polpochila. The species is known from North America, with records from Mexico and the United States. As a member of Carabidae, it belongs to a large family of predatory beetles commonly found in terrestrial habitats.
Polycentropus arizonensis
Polycentropus arizonensis is a species of caddisfly in the family Polycentropodidae, first described by Nathan Banks in 1905. As a member of the order Trichoptera, it represents one of the diverse aquatic insect groups whose larvae develop in freshwater environments. The species is known from the southwestern United States and adjacent regions of Mexico. Like other Polycentropus species, it likely possesses larvae adapted for predatory or filter-feeding lifestyles in lotic or lentic habitats.
Polyergus mexicanus
Western Amazon Ant
Polyergus mexicanus is an obligate social parasite known as the Western Amazon Ant, widely distributed across western North America. This species is incapable of performing basic colony tasks including foraging, nest excavation, and brood care, and depends entirely on enslaved workers of Formica host species. The species performs dramatic, coordinated raids on Formica colonies to capture larvae and pupae, which are then integrated into the parasite colony. Recent genetic studies have revealed substantial population structure associated with different host species, suggesting incipient speciation into host-specific lineages.
Polyphylla cavifrons
Polyphylla cavifrons is a species of scarab beetle in the family Scarabaeidae. It occurs in the southwestern United States and northwestern Mexico, including Arizona, California, Nevada, and Baja California. The species belongs to a genus known for large-bodied beetles with fan-like antennae in males, though specific details about this species' biology remain limited in published literature.
Ponana dohrni
Ponana dohrni is a species of leafhopper in the family Cicadellidae, subfamily Iassinae, tribe Gyponini. First described by Carl Stål in 1864, this species is currently accepted as valid. Available distribution records indicate occurrence in the southwestern United States (Arizona, Colorado) and Mexico (Veracruz). As a member of the Gyponini, it belongs to a group of leafhoppers characterized by particular morphological features of the head and wing venation, though specific diagnostic traits for this species are not well documented in accessible literature.
Ponana puncticollis
Ponana puncticollis is a leafhopper species in the family Cicadellidae, first described by Spångberg in 1878. It is a member of the large genus Ponana, which contains numerous North and Central American species. The species has been documented across a broad geographic range spanning the southeastern United States and Mexico, with over 950 observations recorded on iNaturalist. As with other cicadellids, it likely feeds on plant phloem, though specific host associations remain poorly documented.
Porcellionides floria
Flowery Blue Isopod
Porcellionides floria is a species of terrestrial isopod (woodlouse) in the family Porcellionidae, first described by Garthwaite and Sassaman in 1985. The species has been recorded in North America and Mexico, with 89 observations documented on iNaturalist as of the source date. Like other members of its family, it is a detritivorous crustacean adapted to life on land.
Praeschausia
Praeschausia is a monotypic moth genus in the family Notodontidae, established by Foster Hendrickson Benjamin in 1932. It contains a single species, Praeschausia zapata, described by William Schaus in 1920. The genus is endemic to Mexico.
