Description.

Wing expanse 30-32 mm in male, 35-39 mm in female. In male genitalia, the juxta is short and ends in 1-3 long spines each side. In female genitalia, the sclerotized base of ductus bursae is diagnostic.

Distribution.

Heilongjiang, Jilin, Liaoning, Inner Mongolia, Beijing, Hebei, Shandong, Henan, Shaanxi, Qinghai, Jiangsu, Shanghai, Zhejiang, Hubei, Jiangxi, Fujian, Taiwan, Guangdong, Guangxi; Russia (Far East), Korea, Japan.

Remarks.

Monema melli was described based on a single male from Guangdong, China. It differs from Monema flavescens by the smaller size and the shorter labial palpus. According to the male genitalia of the holotype examined and provided by Mr. Solovyev, it matches well with that of Monema flavescens . Thus we synonymize Monema melli with Monema flavescens . Solovyev and Witt (2009) treated Monema flavescens var. nigrans as a full species. However, the black form (var. nigrans) and the normal form (flavescens) are from the same population and the var. nigrans do not show any differences in the male or female genitalia with flavescens. Therefore we treat Monema flavescens var. nigrans merely as a dark form. In Guiyang 2.75% of the population of flavescens belonged to the black form; the black individuals can interbreed with the non black individuals and produce fertile offspring ( Long et al. 2008).
