800 G.B. Wiggins and C.R. Parker 46. Micrasema bactro Ross (I) Nearctic, western montane Distribution: Yukon to Utah. Yukon records: 10, 12 (ROME). Biological information: Adults have been collected in the Yukon 23 June – 23 July. Family Goeridae This is a small family widely distributed in the northern hemisphere, but extended to tropical latitudes in Asia and even to southern Africa. There are 4 North American genera comprising about a dozen species. Larvae of most species live in cool running water, and some in the water-saturated muck of spring seepage. Genus Goera. This is the largest genus in the family with 6 species in North America. Larvae that are known live in streams and graze diatoms and organic particles from rocks. 47. Goera tungusensis Martynov (II) Holarctic Distribution: Northwest Territories, Quebec; Siberia. Yukon records: This species is included provisionally in the Yukon fauna on the basis of a single female collected in the Northwest Territories, very close to the Yukon border (Midway L., 67°14′N 135°26′W, 8 July85, SMDV). This female is similar to, but not entirely identical with, the female of G. tungusensis from Siberia. Taxonomic notes: See Taxonomic Note 2. Family Lepidostomatidae This family is widely distributed in the northern hemisphere, with some 70 Nearctic species. Two genera are recognized in North America, Theliopsyche and Lepidostoma, with most species assigned to the latter; 4 subgenera have been proposed for species in Lepidostoma, 3 of them represented in the Yukon fauna. No Holarctic species are known. Larvae of most species live in cool, running water, where they are important detritivores; some Lepidostoma larvae live in the littoral zone of lakes. Genus Lepidostoma. This genus is widely represented in North America and Eurasia. 48. Lepidostoma cascadense (Milne) (I) Nearctic, western montane Distribution: Yukon, Alaska to California. Yukon records: 17 (NW 1984). Biological information: Adults have been collected in the Yukon 28 June – 24 July. 49. Lepidostoma cinereum Banks (I) Nearctic, transcontinental, western montane Distribution: Yukon, Alaska to California and Utah, to Newfoundland and Maine. Yukon records: 10, 14 (ROME); 11 (NW 1984). Biological information: Adults have been collected in the Yukon 5 July –12 August. Taxonomic notes: Lepidostoma strophe Ross is a junior synonym. 50. Lepidostoma pluviale (Milne) (I) Nearctic, western montane Distribution: Yukon to California. Yukon records: 10, 16, 19 (ROME). Biological information: Adults have been collected in the Yukon 27 July – 9 August. Taxonomic notes: Lepidostoma veleda Denning is a junior synonym. 51. Lepidostoma roafi (Milne) (I) Nearctic, western montane Distribution: Yukon, Alaska to California. Yukon records: 17 (NW 1984). Biological information: Adults have been collected in the Yukon 28 June – 24 July. 52. Lepidostoma stigma Banks (I) Nearctic, western montane Distribution: Yukon to Utah. Yukon records: 17 (NW 1984). Biological information: Adults have been collected in the Yukon 24 July.
Caddisflies of the Yukon 801 53. Lepidostoma unicolor (Banks) (I) Nearctic, transcontinental, western montane Distribution: Yukon to Quebec, California, and Arizona. Yukon records: 10 (ROME, SMDV). Biological information: Adults have been collected in the Yukon 4 – 9 August. Family Leptoceridae The Leptoceridae are a large family represented on all continents. In North America there are approximately 100 species assigned to 8 genera, 5 of which are represented in the Yukon fauna. Larvae live in lakes, marshes, and slow rivers, feeding on organic particles and aquatic plants, or on insects. Genus Ceraclea. Of some 36 North American species in this genus, 4 are known in the Yukon. Larvae live in large rivers and the littoral zone of lakes where some species feed on colonies of freshwater sponges (Resh et al. 1976). 54. Ceraclea annulicornis (Stephens) (II) Holarctic, transcontinental Distribution: Yukon, Alaska to California, Newfoundland and Kentucky; northern Europe and Asiatic Russia to the Amur region and Japan (Lepneva 1966). Yukon records: 4 (SMDV). Biological information: Adults have been collected in the Yukon 3 July. 55. Ceraclea cancellata (Betten) (I) Nearctic, transcontinental Distribution: Yukon, Alaska to Newfoundland, south to Florida and Arizona. Yukon records: 10, 12 (ROME). Biological information: Adults have been collected in the Yukon 20 July – 9 August. 56. Ceraclea nigronervosa (Retzius) (II) Holarctic Distribution: Yukon, Alaska, British Columbia and Wyoming; northern Europe and Asia. Yukon records: 4, 10, 12, 17 (ROME, SMDV). Biological information: Adults have been collected in the Yukon 5 June –11 July. Taxonomic notes: See Taxonomic Note 3. 57. Ceraclea resurgens (Walker) (I) Nearctic, transcontinental Distribution: Yukon, Oregon to Maine and Louisiana. Yukon records: 10, 12, 14, 15 (ROME, SMDV). Biological information: Adults have been collected in the Yukon 17 – 28 July. Genus Mystacides. This is an Holarctic and Oriental genus with 3 widely distributed North American species; larvae live in standing or slowly moving water, where they are mainly predacious. 58. Mystacides alafimbriata Hill-Griffin (I) Nearctic, western Distribution: Yukon, Alaska to California and Mexico. Yukon records: 10, 17 (ROME); 12 (NW 1984). Biological information: Adults have been collected in the Yukon 2 July – 5 August. Taxonomic notes: See Taxonomic Note 4. 59. Mystacides interjectus (Banks) (I) Nearctic, transcontinental Distribution: Yukon, Alaska to Quebec, Massachusetts and Ohio. Yukon records: 4, 10, 12, 17, 19 (ROME, SMDV). Biological information: Adults have been collected in the Yukon 24 June – 5 August. Taxonomic notes: See Taxonomic Note 5. 60. Mystacides sepulchralis (Walker) (I) Nearctic, transcontinental Distribution: Yukon, Alaska to California, Newfoundland and Georgia. Yukon records: 4, 5, 8, 10, 12, 14, 16, 17, 19 (ROME, SMDV). Biological information: Adults have been collected in the Yukon 26 June –19 August. Taxonomic notes: See Taxonomic Note 4.
