Taxonomically-doubtful
Guides
Dermestes rattus
Dermestes rattus is a species of hide beetle in the family Dermestidae, described by LeConte in 1854. The species is currently listed as taxonomically doubtful in major databases. As a member of the genus Dermestes, it belongs to a group of scavenging beetles commonly employed in forensic entomology and museum specimen preparation for cleaning skeletal remains. The specific biology and ecology of D. rattus remain poorly documented compared to better-known congeners such as D. maculatus and D. lardarius.
Enallonyx
Enallonyx is a genus of soft-winged flower beetles (family Melyridae) described by Wolcott in 1944. The genus is poorly documented, with minimal available information regarding its constituent species, biology, or ecology. Its taxonomic status is flagged as doubtful in some databases, suggesting potential issues with its validity or circumscription. The genus belongs to a family characterized by soft, flexible elytra and frequent association with flowers.
Exon
Exon is a genus of parasitoid wasps in the family Platygastridae, described by Masner in 1980. These are minute wasps that develop as parasitoids of insect eggs. The genus is currently classified as taxonomically doubtful (DOUBTFUL status in GBIF), indicating uncertainty about its validity or circumscription. Platygastridae as a whole are understudied, and detailed biological information for this genus is extremely limited.
Philoxenus
Philoxenus is a genus of clown beetles in the family Histeridae, described by Mazur in 1991. The genus is classified within the subfamily Saprininae. Its sole known species, Philoxenus desertorum, is currently treated as a synonym of Hypocaccus desertorum. The genus name derives from Greek, meaning "lover of foreigners" or "hospitable".
Plebejus glandon punctatus
Plebejus glandon punctatus is a subspecies of the Arctic blue butterfly, a small lycaenid found in mountainous regions of Europe. The subspecies was described by Austin in 1998 and is currently listed as taxonomically doubtful by GBIF. Like other members of the P. glandon complex, adults are associated with alpine and subalpine habitats where their caterpillars develop in association with ants.
Rysepyris
Rysepyris is a genus of small parasitoid wasps in the family Bethylidae, first described by Kieffer in 1906. Members of this genus are poorly known, with very few observations and limited taxonomic study. Bethylid wasps are generally ectoparasitoids of insect larvae, particularly beetles and moths.
