818 G.B. Wiggins and C.R. Parker FIGS. 12 –13. Limnephilus fumosus Banks (102) (Limnephilidae) (AK: USNM). 12, Lectotype male, genitalia: a, lateral; b, dorsal; c, caudal; d, phallus, lateral; e, phallus, dorsal; 13, Paratype female, genitalia: a, lateral; b, ventral. lus isobela Nimmo (1991) as a junior subjective synonym of L. fumosus Banks; the type locality given for L. isobela Nimmo is Isobel Pass (= Isabel or Isabell Pass) mi. 206, Richardson Highway, Yukon, but the Richardson Highway and Isabel Pass are within Alaska. Males of the 2 species can be separated by the parameres, which are bifid apically in L. fumosus (Fig. 12) but undivided in L. santanus (Fig. 14). The females are distinguished by the structure of segment X; in L. fumosus segment X is produced as a pair of heavily sclerotized blade-like projections (Fig. 13), broad apically in ventral aspect with the posterior margin broadly U-shaped. In females of L. santanus (Fig. 15) segment X terminates in a pair of elongate slender processes, and in ventral aspect is narrowed apically. In addition to genitalic differences, L. fumosus and L. santanus differ in the colour of the forewings: Limnephilus fumosus is uniformly brown with conspicuous light areas, much as illustrated by Banks (1900, fig. 10), whereas L. santanus is brown with light speckling widely distributed over the wing, in addition to the large light areas along the chord and at the apex, as described by Ross (1949).
Caddisflies of the Yukon 819 FIGS. 14 –15. Limnephilus santanus Ross (Limnephilidae) (OR: INHS). 14, Holotype male, genitalia: a, lateral; b, dorsal; c, caudal; d, phallus, lateral; e, phallus, dorsal; 15, Allotype female, genitalia: a, lateral; b, ventral. Ross (1949) stated that the type of L. fumosus is a female; however, a type has not been designated. Therefore, we select the following male from the type series as the lectotype of Limnephilus fumosus (Banks, 1900): LECTOTYPE male: Alaska, Berg Bay, June 10 ’99; Harriman Expedition ’99, T. Kincaid, collector; #192, USNM Paratype (sensu cotype) No. 5262. Records confirmed for Limnephilus fumosus indicate that this species is known from Alaska, Yukon, and the Northwest Territories (NT: Midway L., 67°14′N 135°26′W, 8.vii.1985, SMDV). A series in the ROME identified as L. santanus was cited by Nimmo and Wickstrom (1984: YT. Mirror Creek, Alaska Hwy. mile 1209, 28.vi.1958, ROME); these specimens have been re-examined in light of the information now available for these 2 species, and they are L. fumosus. Nimmo’s list of Alaskan Trichoptera (1986) includes L. fumosus based on earlier records from the literature, and also L. santanus based on material
