New species of Cirratulidae (Polychaeta) from the northeastern United States

AbstractDioryctria resinosella, a species feeding on red pine cones or shoots, is described as new and recorded from Maine, southern Ontario, Wisconsin, and Minnesota. The new species is distinguished from D. zimmermani (Grote) and D. banksiella Mutuura & Munroe by the differences in wing markings, genitalia characters, and ecological aspects.

Three new species of Gyroporus, one from the southern hemisphere (Gyroporus madagascariensis sp. nov.) and two from the northern hemisphere (Gyroporus borealis sp. nov. and Gyroporus smithii sp. nov.), are described. G. madagascariensis is a brownish bolete currently known from Madagascar; it has a mottled pileus somewhat reminiscent of G. mcnabbii, another species known from the southern hemisphere. G. borealis is known from the northeastern United States and is also recorded from the northwestern United States under planted landscape trees. G. smithii corresponds to an orange-colored species that has often been encountered in the United States west and south of the Appalachian Mountains (east of the Great Plains) and is likely often mistaken for G. borealis, which can display orange coloration. Additionally, this study presents evidence that G. roseialbus Murrill and G. subalbellus Murrill, previously synonymized by Rolf Singer, are in fact distinct species.

Abstract The highly fossiliferous St. Marys Formation is exposed along Calvert Cliffs, Maryland, and comprises one of the best available records of late Miocene life in the northeastern United States. Rachycentron stremphaencus new species, a cobia from the late Miocene (Tortonian) of the St. Marys Formation is described herein on the basis of a single three-dimensional neurocranium. This fossil represents the earliest known occurrence of neurocranial remains of the genus Rachycentron in the record. Rachycentron stremphaencus differs from Rachycentron canadum (Linnaeus, 1766) in many ways. The most obvious include a different ornamentation of the outer surface of the cranial bones; a notably pronounced lateral ridge resulting in a considerable gradient from the dorsal-medial exposure of the frontal to its lateralmost supraorbital margin; the size, shape, and position of the sphenotic that is located in the posterior half of the neurocranium and its lateralmost edge being adjacent to the anteriormost extent of the wedge-shaped trough in the dorsal surface of the skull formed by the lateral and medial ridges; the two contralateral medial ridges forming a proportionately much wider trough on either side of the supraoccipital; the epioccipitals not reaching the rear edge of the neurocranium; and the lack of a conspicuous posterolateral prong of the intercalar.
