Collctidae

Collctidae is not a recognized taxonomic family in contemporary zoological nomenclature. The name is commonly regarded as a misspelling or historical variant of Colletidae, a valid family within the order Hymenoptera. As such, there is no distinct diagnostic description or accepted classification for Collctidae as a separate lineage.

In modern references, Collctidae is typically treated as a typographical error or a synonymizing artifact rather than a legitimate taxon. The family Colletidae, to which it is often linked by confusion, is widely accepted and studied under that name.

Colletidae comprises several genera of solitary bees and is traditionally divided into subfamilies such as Colletinae and Hylaeinae. Members are generally known for nesting in cavities or in the ground, and many produce a cellophane-like lining in their nests. They tend to be generalist or floral-visitor species, contributing to pollination across a range of habitats. The group's distribution is worldwide, with particular diversity in temperate regions.

Nomenclature notes: The correct spelling and accepted rank for this lineage in current taxonomy is Colletidae. When Collctidae appears in a source, it is most often a misspelling or misinterpretation rather than an independently defined family. For accurate taxonomy, researchers refer to Colletidae and its subfamilies and genera.
