A. sulcicollis (Stephens 1835). (Brekke: A. cinera Olivier)<br />
Earlier records in West Norway: Laerdal SFi (M.O.).<br />
Own records: Sauda and Suldal Ri. 4 3 and 3 9 3115-64,316-<br />
61, 25/6-64, 27/6-64, 3016-62.<br />
186 nymphs were found, the younger stages in January and<br />
February. From 116 to 3016, male and female nymphs were found<br />
ready for emergence. The nymphs agree closely with Hynes's<br />
description. The colour is dark brown on the dorsal side, paler<br />
on the ventral side. The ventral side is somewhat more reddish<br />
than in A. borealis. The sout bristles on the femura are distinct.<br />
In the anterior part of the cerci the bristles are about half the<br />
length of the joints (fig. 10B) ; in the posterior part, the bristles<br />
are less than half the length of the joints. The length of the<br />
full-grown nymphs 4-5 mm. The adults agree closely with<br />
Illies's description. Length of the females 6-7 mm, the males<br />
about 6 mm.<br />
Genus Nemoura (Latreille) Pictet, 1841<br />
Nemoura cinera (Retzius, 1783). (Brekke : N. variegata Olivier) .<br />
Earlier records in West Norway: Herdla, Hagavik og Bergen<br />
HOy (Kn), Laerdal, Kvamma, Eggum, Maristova SFi (M.O.).<br />
Own records: Sauda and Suldal Ri. 15 nymphs were found, the<br />
younger stages on 3111. Full-grown male nymphs ready for<br />
emergence were taken on 2716. Length 6-8 mm. On 25 May 1962<br />
4 3 and 4 9 nymphs ready for emergence were taken from the<br />
stomach of a trout in Suldalsligen. The specimens were determined<br />
by means of adult character after removing the nymph<br />
skin. The nymphs agree closely with Hyne's description.<br />
Genus Nemurella Kempny, 1898<br />
Nemurella picteti KlapAlek, 1900.<br />
Earlier records in West Norway: Bergen HOy (Kn), Laerdal,<br />
0deg;rd SFi (Kn).<br />
Own records: Sauda and Suldal Ri. Only 3 nymphs were found<br />
3016-62 and 14/9-61. The nymphs agree closely with Hynes'<br />
description. This is the only specimen determined by nymphal<br />
characters only. As the species is very conspicuous the determination<br />
is beyond all doubt.<br />
