Macrochelidae
family of arachnids
Macrochelidae is a family of mites in the order Mesostigmata.
Description
Adult females of Macrochelidae have: an undivided dorsal shield bearing at least 28 pairs of setae, a sternal shield with three pairs of setae, a genital shield with one pair of setae and with a pair of conspicuous accessory sclerites beneath lateral margins, usually a ventrianal shield with 1–5 pairs of setae in addition to circumanal setae, peritreme usually looped around stigma, and movable cheliceral digit usually with a well-developed arthrodial brush at the base. Adult males are similar but with a holoventral shield or separate sternigenital and ventrianal shields.
Reproduction
Macrochelidae reproduce sexually and some can also reproduce asexually. Species of Geholaspis and Macrocheles can perform thelytoky, the production of female offspring from unfertilised eggs. Species of Glyptholaspis, Holostaspella and Macrocheles can perform arrhenotoky, the production of male offspring from unfertilised eggs.
Ecology
Mites of this family are predators. The majority of species are coprophilous, meaning they live in animal dung and feed on the prey available there (oligochaete worms, nematodes, arthropod eggs and larvae). Dung offers high prey availability and shelter from the weather, but it is a temporary resource. Melicharids therefore attach to insects (e.g.
This brief starts where responsible research should: with the source description of “Macrochelidae” as family of arachnids. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as family of arachnids. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 23, 2026. The linked authority identifier is Q3274878. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
