Anania shanxiensis
species of moth
Anania shanxiensis is a moth in the subfamily Pyraustinae of the family Crambidae. It was described by Zhaofu Yang and Jean-François Landry in 2019 as Anania sinensis, which turned out to be a junior secondary homonym of a previously described taxon, Anania lancealis sinensis (Munroe & Mutuura, 1968). The replacement name for A. sinensis Yang & Landry, 2019 is Anania shanxiensis Yang & Landry, 2019.
Description
With a similar colouration and wing pattern, the imagines (adult moths) of the A. shanxiensis closely resemble those of A. hortulata, as which they might have been misidentified in the past. Both species can be distinguished from each other by a number of genitalic features, such as the number of coils in the female ductus bursae and the male ductus ejaculatorius (eight coils in A. shanxiensis, seven in A. hortulata), the shape of the sella lobe and of its spinulose process, or the structure of the phallic rods.
Genetically, A. shanxiensis and A. hortulata are closely related: In the DNA barcoding fragment of the cytochrome c oxidase subunit I gene, the species exhibit an average of 2.73% of interspecific Kimura two-parameter distance. Using a molecular clock of 0.0115 per site per million years, the divergence time of the sister species A. shanxiensis and A. hortulata is estimated to be 0.9 million years ago.
Distribution
Anania shanxiensis is distributed in the Chinese provinces of Beijing, Gansu, Guangdong, Guizhou, Hainan, Hebei, Henan, Jiangsu, Ningxia, Qinghai, Shaanxi, Shanxi, Sichuan and Yunnan. So far, the species has not been recorded outside of China.
Biology
The larval host plant is probably Marrubium vulgare (Lamiaceae), which was recorded as food plant for Chinese specimens of A. hortulata, a likely misidentification of A. shanxiensis.
The public source identifies “Anania shanxiensis” as species of moth. This brief keeps that definition visible, then builds a research path around Anania, shanxiensis and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Anania shanxiensis”, the useful work is to connect “species of moth” to the records capable of establishing context and consequence.
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 Aug 29, 2026. The linked authority identifier is Q85741477. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2019 and 1968.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
