Chinoperla rhododendrona Cao & Bae

( Figs. 11-18 )

Chinoperla rhododendrona Cao & Bae, 2007:125 . Holotype ♂ (Aquatic Insect Collection, Seoul Women’s University), Do Quyen stream, Bach Ma National Park , Thua ThienHue Province, Vietnam

Material examined. Vietnam: Thua Thien-Hue, Vietnam, Bach Ma National Park, small stream ca. 200 m along Five Lakes Trail , 1200 m, 16° 11’ 37.4” N, 107° 51’ 19.5” E, 4-16 June 2000, ROM 2000505, B. Hubley, 1♂ ( ROM). Same site, 7-16 June 2000, ROM 2000515, B. Hubley, 1 pinned ♀ ( ROM).

Remarks. The aedeagus of this species is shaped somewhat like that of C. sila and it is also similar in having the dorsal surface of the median process of tergum 9 covered with tooth-like projections (present in our specimen but not mentioned by Cao & Bae, 2007). The two species differ markedly in the shape of the apical process on the dorsal aedeagal lobe, and this species appears to lack the pale wing margin found in C. sila . The everted sac of the aedeagus is short, has a basal membranous lobe and is armed over much of its surface with small triangular spines, not shown by Cao & Bae (2007). The female, collected at the same site as our male is slightly darker but shares the same weakly banded hind leg pattern, and unlike the female of C. rhododendrona described by Cao & Bae (2007), it lacks a mesal notch on the subgenital plate. The egg, however, is similar to that described by Cao & Bae (2007). We include Figs. (11- 18) to assist in recognition of this species.
