A new genus, Cyclomacula Qiao & Wang, gen. nov., is established to accommodate a new species and three new combinations from China: C. medogensis Qiao & Wang, sp. nov., C. glaucinoptera (Collenette, 1934), comb. nov., C. dudgeoni (Swinhoe, 1907), comb. nov. and C. flavimacula (Moore, 1865), comb. nov. Images of adults and genitalia of all currently recognized Cyclomacula species are provided, with illustrations of wing venation of the type species in the new genus. A key to species of the genus is presented, along with DNA barcode data.

The tribe Orgyiini, belonging to the subfamily Lymantriinae of the family Erebidae, is primarily distributed in the Old World and Nearctic Realm (
In the present study, we propose a new genus to accommodate a new species and three species previously classified under the complex genus Dasychira Hübner, 1809. We provide illustrations of adults and genitalia of the currently recognized species of the new genus, as well as wing venation of the type species. We also provide a key and DNA barcode data for the species of this genus.
The type specimens of Cyclomacula glaucinoptera (Collenette, 1934), comb. nov. and C. flavimacula (Moore, 1865), comb. nov. are from the Natural History Museum in London, UK. The other specimens were collected by light trap and were deposited at the Insect Collection, Department of Entomology, College of Plant Protection, South China Agricultural University, Guangzhou, China. Photos of male adults were taken with a NIKON CoolPix S7000 digital camera. The male genitalia were examined after the abdomen was removed and boiled in 10% NaOH solution for 3–5 minutes. The genital slides were photographed with a Carl Zeiss Stemi 2000-CS stereoscope. All photos were processed with Adobe Photoshop CC2023 and SAI ver. 2 software. The terminology of adults and genitalia follows
Total genomic DNA was extracted from two or three legs of adults using a TIANamp Genomic DNA Kit (Tiangen Biotech Co. Ltd, Beijing, China). A 658 bp fragment of the mitochondrial gene cytochrome c oxidase I (COI), namely DNA barcode, was amplified from the new species and Cyclomacula glaucinoptera comb. nov., with the universal primers LCO1490 and HCO2198 (

Dasychira glaucinoptera Collenette, 1934, by present designation.
The new genus usually possesses a nearly ring-like basal spot on the male forewings. It can be easily distinguished from the type species of Dasychira and Olene Hübner, 1823 (D. tephra and O. mendosa) by valvae without branching into two arms in the male genitalia. The new genus is also similar to Telochurus Maes, 1984, but can be separated from the latter by the aedeagus without a cornutus.
Labial palpi short and brown. Antennae bipectinate, stronger in male compared to female. Forewings usually with a ring-like basal spot in male, and an irregular, sometimes wavy oblique postmedial fascia in female; wing venation (Fig.
Male genitalia. Uncus short, digitate. Gnathus bifid, each fork crescent-shaped. Valvae board basally, narrowed distally. Saccus small. Aedeagus simple.
Female genitalia. Anal papillae broad. Apophyses well developed. Ductus poorly sclerotized at base. Bursa large, signum sclerotized medially or absent.
The new genus is named after the Latin words “cyclus” and “macula”, which refer to the ring-like basal spot on the forewings.

Holotype : China • ♂; Xizang Autonomous Region, Linzhi City, Medog County; alt. 2400 m; 1 Nov. 2023; Chuhang Qiao & Ziqi Yuan & Liang Guo leg. Paratype: • 1♂; same collection data as for preceding.
The new species is similar to C. glaucinoptera (Collenette, 1934), comb. nov. in male, but can be distinguished from the latter by the hindwings light brown, uncus slightly pointed, valvae with a weak and indistinct saccular process. It also resembles C. dudgeoni comb. nov. in male, but the latter has dark brown wings and longer valvae. The new species differs from C. flavimacula comb. nov. by forewings without a yellow-white crescent spot near anal angle, and gnathus bifurcating into two slenderer forks.

Three of the four recognized species in Cyclomacula gen. nov. were previously classified under the very complex genus Dasychira. However, the valvae of the type species of Dasychira, D. tephra, are divided into two arms (
