Andronova annulata
species of arachnid
Andronova annulata is a species of spider in the family Dictynidae. It is found in Korea and Japan.
Taxonomy
The species was originally described as Lathys annulata by Bösenberg and Strand in 1906 from Japan. A closely related form, Lathys novembris, was described by Dönitz and Strand in the same publication, but this was later considered a synonym of L. annulata.
In 2025, the species was transferred from the genus Lathys to Andronova by Montana and colleagues as part of a comprehensive revision of the family Dictynidae.
Distribution
A. annulata is distributed across Korea and Japan, including Hokkaido, Honshu, Shikoku, and Kyushu.
Description
Andronova annulata is a small spider with a body length of 2.0–2.5 mm in both sexes. The cephalothorax is blackish-brown in color, while the opisthosoma has a light brownish background with indistinct dark reddish-brown markings and scattered fine white spots. The legs are brownish with numerous dark rings or bands.
In females, the chelicerae bear two teeth on the anterior margin (promarginal teeth) and three teeth on the posterior margin of the cheliceral furrow.The epigyne has copulatory openings that come together to form a heart-shaped structure.
This brief starts where responsible research should: with the source description of “Andronova annulata” as species of arachnid. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of arachnid. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Apr 22, 2026. The linked authority identifier is Q136192941. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1906 and 2025.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
