Aphoebantus rattus
Aphoebantus rattus is a species of bee fly (family Bombyliidae) in the subfamily Anthracinae, described by Osten Sacken in 1887. The genus Aphoebantus is part of the tribe Aphoebantini, a group of small, often inconspicuous bee flies. Species in this genus are poorly documented in the literature, with limited biological information available. The genus has been subject to taxonomic uncertainty, with at least one authority suggesting that Epacmus may be a synonym of Aphoebantus rather than a distinct genus.
Cradytes
Cradytes is a genus of soft-bodied plant beetles in the family Melyridae, established by Casey in 1895. The genus has limited documentation and is classified as doubtful in GBIF, indicating taxonomic uncertainty. Only 29 observations are recorded on iNaturalist, suggesting it is rarely encountered or poorly studied. Its placement within Melyridae indicates it belongs to a diverse family of predatory and pollen-feeding beetles.
Hilarimorphidae
hilarimorphid flies
Hilarimorphidae is a small family of flies (Diptera) with uncertain phylogenetic placement. They have been variously associated with Acroceridae or Bombyliidae within the superfamily Asiloidea. The family is primarily Nearctic in distribution and includes both extant and fossil species.
Homocerynea
Homocerynea is a monotypic moth genus in the family Erebidae, established in 1913 by William Barnes and James Halliday McDunnough. It contains a single species, Homocerynea cleoriformis, known only from Arizona. The genus has been classified in various subfamilies, including Phytometrinae within Erebidae and Acontiinae within Noctuidae, reflecting taxonomic uncertainty.
Listronotus lutulentus
Listronotus lutulentus is a species of weevil in the family Curculionidae, originally described by Boheman in 1843. The species has been historically classified under the genus Eupages as Eupages lutulentus, but is currently recognized as belonging to Listronotus. Available records for this species are extremely limited, with only three observations documented on iNaturalist. No specific ecological, behavioral, or economic information has been published for this particular species.
Magdalis aenescens
Magdalis cf-aenescens is a small weevil in the tribe Magdalini, recognized by its metallic bronze or coppery coloration. The genus Magdalis comprises bark- and wood-associated weevils with elongated snouts and compact bodies. This species is part of a taxonomically challenging complex where identification often requires examination of genitalia or host associations. Records indicate association with woody plants, though specific host relationships for this species remain incompletely documented.
Paralithodes rathbuni
spiny king crab, California king crab
Paralithodes rathbuni is a deep-sea king crab in the family Lithodidae, commonly known as the spiny king crab or California king crab. It inhabits the continental shelf and slope off the coast of California and Baja California at depths of 86–380 meters. The species is closely related to P. californiensis, with which it shares the common name "California king crab," and some authorities have suggested the two may be conspecific.
Tycherus ater
Tycherus ater is a species of parasitoid wasp in the family Ichneumonidae, first described by Cresson in 1877. The genus Tycherus belongs to the subfamily Ichneumoninae within the large and diverse ichneumonid wasp family. Very little published information exists specifically for this species, though it has been documented in biodiversity surveys including DNA barcoding studies of Great Smoky Mountains National Park, where a specimen was identified as likely representing a new species to science—suggesting potential taxonomic complexity or misidentification issues within the genus. The specific epithet 'ater' refers to the black coloration typical of many Tycherus species.
