The New World whirligig beetles of the genus Dineutus Macleay, 1825 (Coleoptera, Gyrinidae, Gyrininae, Dineutini)

Abstract: All New World members of the whirligig beetle genus Dineutus Macleay, 1825 are treated. The New World Dineutus are found to be composed of 18 species and 6 subspecies: one species, Dineutus mexicanus Ochs, 1925, stat. n. is elevated from subspecies to species rank, and the subspecies Dineutus carolinus mutchleri Ochs, 1925, syn. n. is synonymized here with the typical form. Lectotypes are designated for Dineutus discolor Aubé, 1838, Dineutes metallicus Aubé, 1838, Dineutus solitarius Aubé, 1838, Dineutes anali… Show more

“…4). However, the distributions of a recently described Dineutus beetle species from the Apalachicola region and its closest congener are proposed to follow an ecotone in stream acidity (Gustafson & Miller 2015;Miller & Bergsten 2012), so differentiation in the case of N. similaris apalachicola should not be ruled out. The narrowness of the contact zone in Florida may best be explained by a combination of selection against hybrids and limited time since contact was established-perhaps very limited if anthropogenic forest clearing has been a factor.…”

“…This also differs from the common pattern, shown by many southeastern USA animals, of an Atlantic/Florida lineage and a Gulf/Texas lineage (presumably deriving from eastern-and western-refuging Pleistocene populations) meeting approximately where N. similaris apalachicola is found (Avise et al 1987;Swenson & Howard 2005;Walker & Avise 1998). Taxa such as N. similaris apalachicola, the beetle Dineutus angusta (Gustafson & Miller 2015) which is also centered on the Apalachicola region, and the Myola frog (Litoria myola) in northeast Queensland, Australia (which also exhibits a small distribution within a "suture zone"), show how differences in ecological and/or historical factors can cause individual taxa to diverge from patterns found in other local community members. Several other southeastern USA cicadas show a different concordant pattern of a "mainland" species or subspecies meeting a Florida peninsula form (e.g., Cicadetta floridensis, Neocicada hieroglyphica johannis, Neotibicen lyricen virescens, and Neotibicen tibicen australis) (see maps in Sanborn & Phillips 2013).…”

“…Terminology of dineutine structures and measurements follows Gustafson and Miller (2015). Images were obtained by use of a Leica MZ16 stereo microscope coupled with the Leica Application Suite V4.4 Extended Depth of Focus module, followed by image preparation with Photoshop CS5 (Adobe Systems Inc., San Jose, California).…”
