844 G.B. Wiggins and C.R. Parker FIG. 20. Distribution of Dicosmoecus atripes (Hagen) (80) and D. obscuripennis Banks (81) (Limnephilidae); the latter is widely distributed in eastern Asia.
Caddisflies of the Yukon 845 FIG. 21. Distribution of the sister species Limnephilus kennicotti Banks (107) and L. fenestratus (Zetterstedt) (101) (Limnephilidae); symbols superimposed indicate occurrence of both species at the same locality. Limnephilus fenestratus (Zetterstedt) (101) The very similar sister taxon of L. fenestratus is L. kennicotti (107) (category I), which occurs widely through northern North America and in Greenland (Fig. 21). We have identified both taxa in separate collections from the Yukon (Kluane and Firth River). The two are most readily separable by male genitalic structure: in L. fenestratus the intermediate appendages are relatively short and do not extend beyond the superior appendages in lateral aspect, but are longer in L. kennicotti and do extend beyond the superior appendages in lateral aspect. Diagnostic characters for males and females of both species were illustrated by Kimmins and Denning (1951, figs. 10, 11, as L. miser McLachlan which is a junior subjective synonym of L. fenestratus proposed by Schmid 1955; and figs. 12, 13, as L. moselyi Kimmins and Denning from Greenland which is a junior subjective synonym of L. kennicotti proposed by Ross and Merkley 1952). We presume that records of L. fenestratus from Greenland by Fristrup (1942), repeated by Gislason (1981), were based on Mosely’s (1929) misidentification of L. kennicotti as L. miser (= fenestratus); a series of specimens we examined from Greenland (Zoologisk Museum, Copenhagen, per N.P. Kristensen) proved to be L. kennicotti. From the Yukon, Nimmo and Wickstrom (1984) do not record L. fenestratus, but provide several records for
