Panorpa maershana Wang sp. nov.

( Figs 86–95 )

Type material. HOLOTYPE: J ( CN23 Piskmes001), CHINA: YUNNAN: Dali Bai Autonomous Prefecture, Heqing County, eastern slope of the Ma’er (Horse Ear) Mountain , 26°15′35″N, 100°08′43″E, 2650 m, 7.vii.2023, leg. Ji-Shen Wang ( DALU) . PARATYPES: 1J 7♀♀ ( CN 23Piskmes002–009), same data ( DALU).

Diagnosis. This new species can be differentiated from the other members of this group by the combination of the following characters: 1) wings with greatly reduced apical band in both sexes ( Figs 86, 87 ), in males, 2) dorsal branch of parameres extending nearly to apex of ventral valves of aedeagus ( Figs 92, 93 ); 3) ventral branch of parameres approximately 2/3 as long as dorsal branch ( Figs 92, 93 ); 4) dorsal processes of aedeagus nearly truncated apically with shallow median cleft ( Fig. 93 ); in females, 5) subgenital plate with its apical prominence lacking emargination terminally ( Fig. 94 ); 6) laterotergites IX greatly elongated, approximately 3/4 as long as subgenital plate, and with membranous region latero-subapically ( Fig. 94 ); and 7) medigynium with apodemes of axis only slightly extending beyond main plate and widely divergent ( Fig. 95 ).

Measurements (mm). Male (n = 2): AtL 9.8–10.0, AbL 11.2–11.4, BdL 14.8–14.9, FL 11.7–11.8, FW 2.9, HL 10.5–10.6, HW 2.8. Female (n = 7): AtL 10.0–10.8, AbL 8.2–8.8, BdL 12.0–12.7, FL 12.0–12.4, FW 3.0–3.1, HL 11.0–11.3, HW 2.9–3.0.

Etymology. Named after the type locality, Ma’er Mountain (Ma’er Shan in Chinese). Adjective.

Distribution. China: Yunnan: Heqing: Ma’er Mountain ( Fig. 212 ).
