Yufengus Lin, Lin & Epstein gen. nov.

Type species.

Yufengus atrophaneuroides sp. nov. (here designated).

Diagnosis.

No known adults or larvae of Limacodidae from Asia are similar in general appearance to Yufengus . Structurally they are most comparable to Phrixolepia as larvae (Figs 36–39 View Figures 23–40 , 52–56 View Figures 41–58 ) and adults (Figs 57 View Figures 41–58 , 58 View Figures 41–58 ), although adult Phrixolepia forewing lacks the distinct white forewing spots and dark subapical marking on ventral surface (Figs 9–12 View Figures 9–12 ), have male filiform (Fig. 15 View Figures 13–16 ) rather than bipectinate antenna (Fig. 13 View Figures 13–16 ), have Rs 4 originating beyond discal cell (Fig. 18 View Figures 17, 18 ) rather than from discal cell, have gnathos present (Fig. 21 View Figures 19–22 ) rather than absent, have coiled ductus bursae (Fig. 22 View Figures 19–22 ) rather than straight, and the labial palp 3 rd segment is much shorter compared to 2 nd segment compared to Yufengus (Fig. 16 View Figures 13–16 ) (Note: the description of Yufengus is found below under Y. atrophaneuroides ).

Etymology.

The genus is named after Dr Yu-Feng Hsu, the advisor of the first two authors, who has provided support and encouragement for limacodid studies over the past 10 years.
