A New Species of Melanoplus (Orthoptera: Acrididae) from the Cumberland Plateau of Tennessee, USA.

We describe a new species in the caddisfly genus Rhyacophila (Trichoptera: Rhyacophilidae) from the southern Cumberland Plateau of the United States. Rhyacophila dandaganu n. sp. is placed in the Rhyacophila lobifera Group from North America, the second known species in this group. The new species is distinguished from Rhyacophila lobifera Betten, 1934 by the shape and dimensions of several genitalic structures, as well as the absence of parameres accompanying the endotheca and the characteristic shape of the tenth segment and phallicata. We discuss the geographic range of these two species and the questions raised by the curious (apparent) lack of sympatric populations. We discuss some testable hypotheses that might determine how populations of R. dandaganu n. sp. and R. lobifera could maintain phenotypic distinctiveness, in the absence of obvious geographic barriers to gene flow, including behavioral, chemical or tactile mating cues.

A New Species

A new species of eastern Nearctic snowfly, Allocapnia tsalagi, is described from Jackson Co., Alabama, U.S.A. The new species is distinguished from closely-related A. malverna and A. mohri by details of the epiproct. Additionally, the dorsal process of the 8 th abdominal tergite of morphologically-variable A. recta is illustrated from the Cumberland Plateau region of northeastern Alabama.

We describe the new species, Nesticus pecki, an apparently cave-limited (but not troglomorphic) species from the southeastern edge of the Cumberland Plateau in southern Tennessee. Previously unknown males of N. dilutus Gertsch, N. stygius Gertsch, and N. furtivus Gertsch are illustrated and described. These male specimens, along with additional females, are all taken from their respective type localities. Nesticus valentinei Gertsch is considered a junior subjective synonym of N. barri Gertsch (new synonymy). Several cave-limited species in the region are single-site endemics, including N. furtivus, N. dilutus, and N. pecki. We discuss the conservation status and biological factors that may potentially threaten the continued existence of these populations.
