Paraleuctra occidentalis (Banks)

Leuctra occidentalis Banks, 1907:329 .

Lectotype ♀ (Museum of Comparative Zoology, Harvard University), Laggan , Alberta, designated by Ricker, 1952

Leuctra bradleyi Needham & Claassen, 1925:225 .

Holotype ♂, damaged (Cornell University), Emerald Lake , Canadian Rockies

Material examined. Canada: Emerald Lake, Canadian Rockies, P. bradleyi holotype, abdomen lost ( Cornell University ). Alberta, Laggan , 22 July 1901, R. Osburn , lectotype ♀ ( Museum of Comparative Zoology ). Same location, 23 August 1902, R. Osburn, paralectotype ♀, abdomen lost ( Museum of Comparative Zoology ) .

Remarks. The female specimen in the MCZ which Ricker (1952) selected as lectotype was not labeled as such, but he indicates it is the “complete ♀ specimen” and by elimination, the specimen listed above must be the lectotype. The second MCZ specimen (paralectotype), collected at Laggan, “BC” on 23 August 1902 has no abdomen. We clipped the lectotype abdomen, cleared it and found it to be consistent with the figure of P. occidentalis (Fig. 32) provided by Stark & Kyzar (2000). We also accept the Ricker (1954) synonymy of P. bradleyi with P. occidentalis based on the figures provided by Needham & Claassen (1925) on Plate 41 of that publication.
