Aphelia
Aphelia is a genus name with multiple unrelated applications across biological and non-biological domains. In zoology, Aphelia is a genus of tortricid moths (family Tortricidae, order Lepidoptera). In botany, Aphelia is a genus of monocot plants in the family Restionaceae (order Poales), with authority R.Br., 1810. The name also appears in astronomy as the plural of aphelion, referring to the points in solar orbits most distant from the Sun. This record addresses the biological taxa only; the astronomical usage is nomenclaturally coincidental.
Contacyphon
marsh beetles
Contacyphon is a genus of marsh beetles in the family Scirtidae, comprising over 100 described species. The genus was established to accommodate species formerly placed under the invalid name Cyphon. These beetles are associated with moist habitats and are frequently encountered at artificial lights.
Devia
Devia is a genus of rove beetles in the family Staphylinidae, subfamily Aleocharinae. The genus was established by Blackwelder in 1952 and is classified within the tribe Oxypodini. Rove beetles in this genus are small, elongate beetles with the characteristic abbreviated elytra that leave much of the abdomen exposed. The genus is distinct from the plant genus Devia (Iridaceae), which was described later by Goldblatt & Manning in 1990.
Echemus
Echemus Simon, 1878 is a genus of ground spiders in Gnaphosidae. GBIF treats it as accepted and records 25 descendants, while the World Spider Catalog lists 24 accepted species and four synonyms; the difference reflects database scope and name treatment rather than a species-level conclusion here. The catalog identifies Echemus ambiguus as the type species name and records it as a synonym of Echemus angustifrons. The consulted genus-level records provide strong taxonomic information but do not support one uniform description of appearance, habitat, diet, or seasonality for all Echemus species.
Incertae sedis
Incertae sedis is a taxonomic term used to indicate that a taxon's placement within a higher classification is uncertain or unresolved. It does not represent a biological group but rather a placeholder status pending further research. The term applies to taxa whose relationships to other groups remain unclear due to insufficient morphological, molecular, or fossil evidence.
La cerveza
La cerveza is a moth species in the family Crambidae described by Bernard Landry in 1995. The species name is a pun in Spanish meaning "the beer," reflecting a pattern of humorous nomenclature within the genus La. It has been documented in four southwestern U.S. states.
Ochterus perbosci
Ochterus perbosci is a species of velvety shore bug in the family Ochteridae. The species name was originally published as O. perboscii by Guérin-Méneville in 1843, but the spelling O. perbosci became established in prevailing usage and was formally fixed under ICZN Article 33.3.1. The name-bearing type has been designated as a lectotype. Like other members of Ochteridae, it is an aquatic bug associated with riparian habitats.
Pityobiinae
Pityobiinae is a subfamily of click beetles (family Elateridae) established by Hyslop in 1917. The subfamily contains two valid genera: Pityobius (Leconte, 1854) and Tibionema (Solier, 1851), with at least two described species. It is one of ten subfamilies treated in recent nomenclatural catalogues of Elateridae genus-group names. The classification follows Costa et al. (2010) with subsequent modifications by Kundrata et al. (2016).
Undescribed
undescribed taxon, undescribed species
An undescribed taxon refers to any organism that has been discovered but not yet formally described and named according to established nomenclatural codes. These taxa lack official scientific names, though temporary informal designations are commonly used in practice. The phenomenon spans all major organismal groups, with particularly high prevalence in insects, fungi, and tropical invertebrates. Modern molecular techniques have dramatically accelerated discovery of undescribed diversity, revealing cryptic species that appear morphologically identical but are genetically distinct. The interval between discovery and formal description averages 13–21 years, creating a substantial backlog known as the 'taxonomic impediment.'
