Hong Kong Moths 香港蛾類

A series of three papers in the journal Zootaxa were published in 2020 and 2021 on the genus Stathmopopda from China.
Specifically:

1. Wang, A.L.; Guan, W. & Wang, S.X., 2020. Genus Stathmopoda Herrich-Schäffer, 1853 (Lepidoptera: Stathmopodidae) from China: Descriptions of thirteen new species. Zootaxa 4838 (3): 358-380. DOI:10.11646/zootaxa.4838.3.3
2. Wang, A.L.; Wang, S.X. & Guan, W., 2021. Genus Stathmopoda Herrich-Schäffer, 1853 (Lepidoptera: Stathmopodidae) from China: Descriptions of ten new species. Zootaxa 4908 (4): 451-472. DOI:10.11646/zootaxa.4908.4.1
3. Wang, S.X., Guan, W. & Wang, A.L., 2021. Genus Stathmopoda Herrich-Schffer, 1853 (Lepidoptera: Stathmopodidae) from China (III): Descriptions of fourteen new species. Zootaxa 5039 (1): 71-108. DOI:10.11646/zootaxa.5039.1.3

The individual species treatments and figures are all avaliable via Zenodo, and I've linked to the adult habitus plates here, below, with HK species captioned in the figure legends in bold font and marked with ^HK. Scales = 2 mm.

What this means is that we now have a better understanding of the Hong Kong stathmopodid fauna, with resolution of three spp nov from HK and the id of at least two other species. The second and third papers specifically deal with HK material, and the first paper has spp nov that look allied to some of the yellow and dark brown HK species awaiting an id.

There are 6 HK species treated:
S. orbiculata Meyrick, 1913 (already known from HK and correctly identified)
S. tetracantha Wang, Wang & Guan, 2021 - one of the known unkowns, now described.
S. xanthomochla Meyrick, 1913 (already known from HK and previously tentatively identified as sp A near xanathomochla)
S. similignominiosa Wang & Guan, 2021 (already known from HK and previously misidentified as S. sycophanta)
S. diplaspis (Meyrick, 1887) - a known unknown, separated from S. paradiplaspis, below, by the orange (not dark brown) thorax and patagia; separated from S. octicaspis by the lack of eyespot markings on the thorax
S. paradiplaspis Wang & Guan, 2021 - one of the known unkowns, now described; separated from the allied S. diplaspis by the bark, not orange, thorax and patagia and with the sub- and post-medialwhite bands edged with orange.

Further clues to other unidentified HK taxa also in these papers. . . .
The "Stathmopoda near cellifera" is still unresolved, but even closer to the newly described S. triloba
There are at least two further species close to xanthomochla in HK - they differ by the arrangement of the sub-and post-medial banding in placement and thickness of both the black edging and yellow bands; one of the candidate taxa is the new S. apicihamata. The other HK taxa doesn't match any of the xanthomochla group treated in part III
One of the yellow & brown HK species looks allied to S. flavescens.
Still penty of work to be done!
