Cyclomacula, Qiao & Xu & Wang, 2025

Qiao, Chu-Hang, Xu, Yong-Qiang & Wang, Hou-Shuai, 2025, A new genus of Orgyiini (Lepidoptera, Erebidae, Lymantriinae) from China, with description of a new species, ZooKeys 1243, pp. 131-142 : 131-142

Cyclomacula gen. nov.

Type species.

Dasychira glaucinoptera Collenette, 1934 , by present designation.

Diagnosis.

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.

Description.

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. 1 ) with an accessory cell; R 1 branching from distal 1 / 3 of dorsal margin of discal cell, R 2, R 3 + 4 and R 5 arising from accessory cell, respectively; M 1 originated from upper angle of discal cell, M 2 and M 3 originated from lower angle of discal cell, respectively; Cu 1 parallel to Cu 2. Hindwings without markings in male, but an indistinct postmedian fascia often present in female; Rs short stalked with M 1; M 2 present, arising from lower angle of discal cell; Cu 1 parallel to Cu 2.

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.

Etymology.

The new genus is named after the Latin words “ cyclus ” and “ macula ”, which refer to the ring-like basal spot on the forewings.

Distribution.

China (Jiangsu, Zhejiang, Hubei, Hunan, Fujian, Guangdong, Guangxi, Hainan, Shaanxi, Gansu, Sichuan, Yunnan, Xizang); India, Nepal, Malaysia, Indonesia.
