Two New Nymphalidae From Western North Carolina: New Subspecies Of Speyeria Aphrodite And Phyciodes Batesii, Ronald R. Gatrelle Dec 1998

Two New Nymphalidae From Western North Carolina: New Subspecies Of Speyeria Aphrodite And Phyciodes Batesii, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

Two new subspecies are described from Macon County, North Carolina, United States. Speyeria aphrodite cullasaja is characterized by dorsal melanism, especially in females, by usually lacking the dorsal FW basal spots in cell Cu1 and Cu2, and by a narrowed buff marginal band on the ventral HW (sometimes absent in females). Phyciodes batesii maconensis males are characterized by wholly yellow ventral hind wings devoid of any dark marginal dusting or whitish crescents; and females occasionally possessing, lightly dusted, brown margins and rarely having a silvered marginal ventral HW spot. PPhyciodes batesii maconensis larvae are gregarious Aster feeders. Females are …


The Rediscovery, Taxonomy, And Biology Of Chlosyne Gorgone Gorgone And Chlosyne Ismeria (Nymphalidae) In Burke County, Georgia, Ronald R. Gatrelle Nov 1998

The Rediscovery, Taxonomy, And Biology Of Chlosyne Gorgone Gorgone And Chlosyne Ismeria (Nymphalidae) In Burke County, Georgia, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

On April 24, 1993 a colony of Chlosyne gorgone gorgone was found in Orangeburg County, South Carolina, United States. This led to the rediscovery on April 27, 1993 of C. g. gorgone at its type locality in Burke County, Georgia. This species had not been seen or collected anywhere in east coastal Georgia or coastal South Carolina since its description in 1810. The type locality is xeric, scrub oak sandhill. This habitat is generally unsuitable for the survival of later broods. The larvae of nominate gorgone have only been found on Helianthus divaricatus. Topotypical gorgone differ slightly, …


An Addendum To Anthocharis Midea Dos Passos And Klots 1969: Description Of A New Subspecies From Texas, Ronald R. Gatrelle Oct 1998

An Addendum To Anthocharis Midea Dos Passos And Klots 1969: Description Of A New Subspecies From Texas, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

This paper verifies and expands upon the information presented by dos Passos and Klots in their 1969 systematic revision of Anthocharis midea. Their restriction of the range of A. midea midea to the coastal islands and immediate coast of Georgia and South Carolina, United States is confirmed and expanded north into southern coastal North Carolina. Their range of A. m. annickae is expanded southward from Virginia to central Georgia. A new subspecies, A. midea texana, is described from Texas. Texana is annickae’s ancestor. It differs from annickae only in having greatly reduced black scaling …


Population Biology Of Intraspecific Polyploidy In Grasses, Kathleen H. Keeler Jan 1998

Population Biology Of Intraspecific Polyploidy In Grasses, Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

Polyploidy is the duplication of an entire nuclear genome, whether diploid or higher level (Stebbins, 1971; Thompson & Lumaret, 1992) and a frequent occurrence in plants. Stebbins (1971) estimated that 30-35% of flowering plant species are polyploid, and that many more had a polyploid event in their evolutionary history, including all members of such important families as the Magnoliaceae, Salicaceae, and Ericaceae. Goldblatt (1980) estimated 55%, but probably up to 75%, of monocotyledons had at least one polyploid event in their history, using the criterion that if the species has a base number higher than n=13 it is derived …
