Description
Nemoura gemma Ham & Lee, 1998
(Figs. 15, 16)
Nemoura gemma Ham & Lee, 1998:357. Holotype ♂, REPUBLIC OF KOREA, Tugyasan National Park, Chollabuk-do (Chonnam National University, Kwangju).
Material examined. REPUBLIC OF KOREA: Jirisan, Hamyang-gun, Macheon-Myeon, Samjeon-li, Alt. 700 m, 35°20.93'N 125°38.50'E, 11.IV.-8.V. 2004, Malaise trap on small stream, 4♂. Chungbuk, SangchonMyeon, Dungeon-li near Doma Pass, Alt. 750 m, 2.- 26.V. 2006, 2 Malaise traps in forest on small stream, ca. 20♂; same locality but Alt. 500 m, 2.-26.VI. 2006, Malaise trap in forest on small stream, 9♂.
Supplementary description. The paraproct possesses an entire elongate apex. The cercus has a double outer tooth extending slightly further backward than the single inner tooth. In caudal view the edge of the sclerotized area over the membraneous cercus apex is angled, the rudimentary 2 nd cercus segment lies directly below the angle. The soft part extends far mediad and is at the tip irregularly pigmented (Fig. 16).
The beak-like shape of the anterior portion of the short and stout male epiproct is distinctive (Fig. 15). The dark, shining apical sclerites appear like a forward extension of the looped sclerite, not like a structure attaching to it. The slender tip bears some fine asperities. The sharply pointed setae which in most species sit on the lower face of the apical sclerite are clearly visible on the side of the beak-like apex.
The cercus of N. gemma somewhat resembles two new species (N. rugosa, N. lazoensis) which, however, differ strogly in paraproct and epiproct, see below.
