Panorpa yucheni Wang sp. nov.

( Figs 197–205 )

Type material. HOLOTYPE: J ( CN20 Piskyuc001), CHINA: YUNNAN: Nujiang Lisu Autonomous Prefecture, Lushui City, Gaoligong Mountains , Yaojiaping , 25°57′30″N, 98°42′52″E, 2240 m, 13.v.2020, leg. Yu-Chen Zheng ( DALU) . PARATYPE: 1 ♀ ( CN 20Piskyuc002), same data ( DALU).

Diagnosis. This species resembles P. issikiana in the male genitalia, especially in the crossed dorsal branch of parameres and the median cleft of dorsal processes of aedeagus. However, it can be readily differentiated from the latter by: 1) ventral branch of parameres not extending to apex of ventral valves ( Figs 202, 203 vs. exceeding ventral valves in Fig. 2 ); 2) distal portion of ventral branch of parameres tapering towards apex ( Figs 202, 203 vs. enlarged subdistally in Figs 2, 3 ); 3) dorsal processes of aedeagus with apex much elongated ( Fig. 203 vs. shorter in Fig. 2 ); and 4) median cleft of dorsal processes with its length longer than width of dorsal processes ( Fig. 203 vs. shorter in Fig. 2 ). It can also be differentiated from other members in the group by female genitalia: 1) laterotergites IX broad, with caudal margin rounded ( Fig. 204 ); 2) medigynium with posterior arms shorter than half length of main plate ( Fig. 205 ); and 3) main plate of medigynium slightly expanded laterally in basal 1/3 ( Fig. 205 ).

Measurements (mm). Male (n = 1): AtL 12.8, AbL 10.6, BdL 15.0, FL 15.2, FW 3.4, HL 14.0, HW 3.3. Female (n = 1): AtL (broken), AbL 9.4, BdL 13.8, FL 15.8, FW 3.6, HL 14.4, HW 3.4.

Etymology. Dedicated to Yu-Chen Zheng, who collected and donated the specimens. Noun in the genitive case.

Distribution. China: Yunnan: Lushui: Gaoligong Mountains ( Fig. 212 ).
