47. Mustilizans drepaniformis Yang, 1995

Mustilizans drepaniformis Yang, 1995 , Insects of Baishanzu Mountain, Eastern China: 356. TL: “ China, Prov. Zhejiang, Mt. Baishanzu 1600 m ”.

Diagnosis. This species was characterized in the original description by a forewing with a hook-shaped apex, concave outer margin edged with ocher, and a discal cell with a small black spot.

Specimens examined. [ZHEJIANG] Qingyuan County (Lishui City): 1 male, holotype, Mt. Baishanzu, 1600 m, 21.VIII.1994, Hong Wu leg. (ZAU); 2 males, paratypes, Mt. Baishanzu, 550 m, 23.IV.1994, Min Lin leg. (ZAU) (Notes: The type specimens are lost (Zolotuhin, 2007), and the data given here are those provided in the original description).

Bionomics. The larval host is unknown.

Distribution. Mainland China (Zhejiang).

Remarks. The type specimens have been lost (Zolotuhin, 2007) and no more specimens have been collected. According to the original description and other Mustilizans specimens captured since in the type locality, we consider that the type specimens of drepaniformis are probably just variations of M. hepatica . However, more information is needed to confirm this suggestion, and so we here continue to treat drepaniformis as a valid species.

Bionomics. The larval host is unknown.

Distribution. Mainland China (Zhejiang, Jiangxi, Hubei, Shaanxi, Sichuan, Yunnan) and Hainan, Vietnam, Malaysia, Indonesia, Thailand. The Chinese population is attributed to ssp. refugialis by Zolotuhin, (2007) and we used the species name dierli to treat with the subspecies name refugialis here.

Remarks. This species is widely distributed in Southeast Asia and China. Yang (1995b) described a new species baishanzua based on specimens collected from Baishanzu Mountain. Here, we consider that the species baishanzua as a new synonymy of the species dierli based on the comparing detailly with the original description by Yang (1995b).
