The species name 'clytrinoides' suggests a resemblance to the genus Clytrinus, a group of cryptocephaline leaf beetles.
Laemosaccus gossypii
Laemosaccus gossypii is a species of weevil in the family Curculionidae, described by Hespenheide in 2019. The specific epithet "gossypii" suggests an association with cotton (Gossypium), though the exact nature of this relationship has not been detailed in available sources. The genus Laemosaccus is characterized by modified front femora bearing teeth, a trait shared with related anthonomine weevils.
Laemosaccus obrieni
Laemosaccus obrieni is a species of weevil in the family Curculionidae, described by Henry Hespenheide in 2019. The genus Laemosaccus is characterized by modified front femora bearing teeth, a trait shared with certain other weevil genera including Tachygonus. This species belongs to a group of weevils exhibiting structural elaboration of leg segments.
Liriomyza euphorbiella
Liriomyza euphorbiella is a species of leaf-mining fly in the family Agromyzidae, described by Eiseman and Lonsdale in 2019. The specific epithet suggests an association with plants in the genus Euphorbia. As a member of the genus Liriomyza, it belongs to a group of flies whose larvae create distinctive mines within leaf tissue. The species is recognized as valid and accepted in taxonomic databases.
Mixogaster fattigi
Fattig's Ant Fly
Mixogaster fattigi is a species of ant-mimicking hoverfly (family Syrphidae, subfamily Microdontinae) described in 2019. The genus Mixogaster belongs to the tribe Microdontini, a group whose larvae are known to develop within ant colonies as inquilines or predators of ant brood. The specific epithet honors entomologist Delbert La Rue Fattig. The species is part of a lineage exhibiting remarkable morphological convergence with ants, representing an evolutionary strategy to avoid predation while foraging or accessing ant-associated resources.
Ophiomyia antennariae
Ophiomyia antennariae is a recently described species of leaf-mining fly in the family Agromyzidae, described by Eiseman and Lonsdale in 2019. The species is named for its association with host plants in the genus Antennaria (pussytoes), indicating a specialized herbivorous relationship. As a member of the genus Ophiomyia, it likely produces serpentine or blotch mines in leaves, though specific mine morphology has not been formally documented in the original description. The species represents part of the diverse radiation of agromyzid flies that specialize on Asteraceae host plants.
Paraidemona behrstocki
Paraidemona behrstocki is a species of band-winged grasshopper in the family Acrididae, described by Otte in 2019. It belongs to the genus Paraidemona, which is known to serve as prey for parasitoid wasps in the genus Prionyx. The species is part of the Melanoplinae subfamily, a diverse group of grasshoppers primarily found in North America.
Saphenista bartellae
Saphenista bartellae is a small tortricid moth described in 2019. The species occurs in two disjunct populations: a coastal California population found at low elevations, and a montane population ranging from British Columbia through the Sierra Nevada to the Rocky Mountains. Adults fly in mid-summer at high elevations but in autumn along the coast. The species is known from relatively few collections.
Sphecomyia interrupta
Sphecomyia interrupta is a species of hoverfly (family Syrphidae) described in 2019. It is a large wasp mimic within the Holarctic genus Sphecomyia, belonging to the S. vittata species group. The species is characterized by distinctive morphological features including a completely pruinose scutellum without a black posterior rim, an interrupted medial facial vitta, and specific antennal segment proportions. Like other members of subtribe Criorhinina, it likely exhibits Batesian mimicry of stinging wasps.
Sphecomyia oraria
Sphecomyia oraria is a species of hoverfly (Syrphidae) described in 2019. It belongs to the S. pattonii species group within the Holarctic genus Sphecomyia, which comprises large wasp-mimicking flies in subtribe Criorhinina. The species exhibits Batesian mimicry of vespid wasps, particularly yellowjackets. Like other members of its genus, it is presumed to have larvae that develop in rotting wood or tree holes, though this has not been confirmed for S. oraria specifically.
Sphecomyia pseudosphecomima
Sphecomyia pseudosphecomima is a species of hoverfly (Diptera: Syrphidae) described by Moran in 2019. It belongs to the genus Sphecomyia, a Holarctic group of large wasp-mimicking syrphid flies. The species is placed in the S. pattonii species group, characterized by the absence of pruinose scutellar vittae and broadened fore tarsi. Like other members of its genus, it exhibits Batesian mimicry of vespid wasps, though specific details of its biology remain undocumented.
Strumigenys ananeotes
Strumigenys ananeotes is a species of miniature trap-jaw ant described in 2019 from Costa Rica. It belongs to a diverse genus of predatory ants known for their elongated mandibles that snap shut to capture prey. The species name derives from Greek, meaning 'newly emerged' or 'returning to life', possibly referencing its discovery or cryptic habits. Like other members of its genus, it is likely a specialized predator of small soil arthropods.
Xanthonia marquai
Davis Mountains Juniper Xanthonian
Xanthonia marquai is a recently described species of leaf beetle (Chrysomelidae) endemic to the Davis Mountains in western Texas. The species was described in 2019 and is known from a single iNaturalist observation. It is associated with juniper vegetation in montane habitats.
Xanthonia parva
Lacey Oak Xanthonia
Xanthonia parva is a species of leaf beetle in the family Chrysomelidae, described in 2019 from material collected in Texas. It is one of the smallest species in the genus Xanthonia and is associated with Quercus laceyi (Lacey oak). The species was distinguished from congeners based on morphological characters and represents part of ongoing taxonomic revision of North American Eumolpinae.
