Abstract

The disjunct distribution of Cambarus monongalensis has led to speculation about its taxonomic status. An Appalachian Plateau population occurs in northern and central West Virginia and Southwestern Pennsylvania, and a mountain population occurs in the Allegheny Mountains and Ridge and Valley physiographic provinces of the Virginias. Herein we describe the mountain population as Cambarus fetzneri sp. nov. The two species differ genetically and morphologically, and have different color patterns. Specifically, C. fetzneri sp. nov. chelae lack extensive red coloration on the distal end of the propodus and dactyl, possess rostral margins that lack any red coloration, compared to C. monongalensis , which has extensive red coloration on the dactyl and propodus, as well as red rostral margins. Morphologically, the rostrum of C. fetzneri sp. nov. is shorter and wider than that of C. monongalensis . Also, adult C. fetzneri sp. nov. are considerably smaller in body size than those of C. monongalensis .

Systematics of three Amazonian antwren groups (Aves: Passeriformes: Thamnophilidae: Myrmotherula and Isleria)

Working within the framework of a companion phylogenetic analysis, we reexamined species limits within three lineages of antwrens (two species and one species complex) widely distributed across the Amazon Basin. Diagnostic differences in vocal and plumage characters provided the basis for the following taxonomic revisions. Myrmotherula longipennis is found to comprise three species: (1) M. longipennis ( sensu stricto ), which is confined to the region north of the Amazon; (2) M. garbei , which is elevated from subspecies status and includes the subspecies zimmeri ; and (3) M. paraensis , which is also elevated from subspecies status and includes subspecies transitiva and ochrogyna . Myrmotherula menetriesii also comprises three species: (1) M. menetriesii ( sensu stricto ), which occurs in the southwest quadrant of Amazonia and includes the subspecies berlepschi ; (2) M. cinereiventris , which is elevated from subspecies status and includes the subspecies pallida ; and (3) M. omissa , which is monotypic and is also elevated from subspecies status. We maintain two species in the Isleria complex, I. guttata and I. hauxwelli . Isleria guttata remains monotypic, but the subspecies of I. hauxwelli are revised. Isleria h. hellmayri is preserved as currently defined, but I. h. suffusa is synonymized with the nominate form, the geographic range of which is restricted to western Amazonia. A fourth subspecies, I. h. clarior , is resurrected; this subspecies occupies the major part of the range previously assigned to I. h. hauxwelli .

Phylogenomics, male internal genitalia, a new species, and other notes on New World Stenopelmatus Jerusalem crickets (Orthoptera: Stenopelmatoidea: Stenopelmatini)

Based on past and expanded DNA sampling, the orthopteran families Stenopelmatidae and Anostostomatidae, as currently structured, are shown to be non-monophyletic. The splay-footed cricket genus Comicus is confirmed to be genetically distinct from all Stenopelmatidae. We add two specimens to our previously published phylogenetic tree for New World Stenopelmatus Jerusalem cricket species and report the first multilocus DNA recovery for S. ater from Costa Rica. Male internal genitalia may be of systematic value in Jerusalem crickets, but we believe they should be analyzed when in their unfolded, “physiologically functional” configuration, where morphological characters can be seen in more detail when compared to their preserved, folded state. We describe Stenopelmatus nuevoguatemalae n. sp. from Guatemala.
