Memoirs of the American Entomological Society 31, 1-208. PDFQuote from page 94: "This family [Leuctridae] is represented in the Rocky Mountains by five [They discuss 4 genera, but Pomoleuctra has been split out since this publication] genera in two subfamilies. The adults are ususally small and dark grey or black in color. The wings are uniformly dark in color and they tend to curl laterally producing a slightly rolled appearance. The adult cerci are composed of single segment in both males and females. (figs 306, 328). The nymphs are lightly colored and the wing pads are parallel with the body axis. They are similar to the nymphs of the Capniidae but are usually much more elongate. The adults emerge in the spring or summer and a few species as late as early fall. They are often found in springs and the genus Perlomyia seems to be limited to springs and spring fed habitats." Quote about the genus Paraleuctra from page 96: "Paraleuctra exhibits a holarctic distribution pattern and can be common in Rocky Mountain streams. The males have heavily sclerotized cerci that terminate in a fork-like apex (figs. 306, 307). Females are difficult to separate because of their simple bilobed subgenital plate (fig. 311). Two species groups are apparent: the P. sara group, characterized by a simple elongate titillator and the P. occidentalis group, that has a titillator with an enlarged variable apex. The adults emerge in the spring and summer months and are most common in waters influenced by springs.

Abstract: " Larval structures diagnostic of several Plecoptera families, subfamilies or genera are described and illustrated. They concern the following: distinction of larval Leuctridae from Capniidae; an additional apomorphy of Nemouridae; a synapomorphy of Perlidae and Perlodidae; monophyly of each of the two subfamilies of Chloroperlidae, and the generic limits among Chloroperlidae: Paraperlinae. Paraperla lepnevae Zhiltzova is transferred to Utaperla. Some comments on Notonemouridae are included." |
