Shaun
Winterton
After
graduating from the University of Southern Queensland in 1992,
Shaun spent the last three and a half years with the Cooperative
Research Centre for Tropical Pest Management and CSIRO,
researching insect-plant interactions of introduced water
weeds. His taxonomic interests have been on Australian Neuroptera
and he has published studies on the taxonomy and ecology of
the Chrysopidae and Hemerobiidae. |

In July 1996, Shaun started a Graduate Diploma in Entomology
with the University of Queensland,
monographing [a new Australian genus] Winterton & Irwin
(in press), for which he was conferred his Post-Graduate Diploma
in Science (Entomology) in July 1997. In August 1997, he began
a Ph.D. under Dr.
David Yeates and Dr.
Michael Irwin, monographing the endemic Australian genus
Agapophytus (Diptera: Therevidae).
As
part of his Ph.D., and in collaboration with Mr. Stephen Gaimari
and Co-PI's David Yeates and Michael Irwin, Mr. Shaun Winterton
has proposed a standardized terminology for body vestiture
and male genitalia. The former developed using scanning electron
microscopy facilities at the University of Queensland. This
terminology will be adopted in all monographs produced by
the therevid group.
In
collaboration with Dr. David Merritt and Anthony O'Toole (University
of Queensland), Mr. Shaun Winterton, Co-PI David Yeates and
Co-PI Michael Irwin have made detailed studies into the morphology
and histology of a novel structure in the female therevid
reproductive system. The studies include histological sections
of virgin and mated females to determine the possible function
of this structure.

Also
in collaboration with Mr. Anthony O'Toole, Mr. Shaun Winterton
and Co-PI David Yeates have begun to accumulate a photographic
library of live therevids collected from the field. One of these
photographs (of an undescribed genus and species) won first
prize in the photographic competition at the 1997 AGM of the
Australian Entomological Society in September. |

In
October 1996, Shaun accompanied David Yeates on a field excursion
to Great Sandy National Park, Cooloola
Section (southeast Queensland). During September 1997,
Mr. Winterton, with other postgraduate students from the University
of Queensland Entomology department, traveled on a one week
trip to far western Queensland to collect near the town of
Birdsville. Several new species
of desert Therevidae were collected.
The
following month, Mr. Winterton, with other postgraduate students
from the University of Queensland Entomology department, traveled
for one month through Victoria, South Australia and New South
Wales. Collections were made in Wyperfeld, Flinders Ranges,
Dutchmans Stern, Warrumbungle and Gammon Ranges National Parks.
Approximately 40 species from close to 25 genera were collected
during the trip, with greatest diversity in Gammon Ranges
and Warrumbungle National Parks.

September 1998, Shaun attended the International Congress of
Dipterology in Oxford, England to present his work on the female
reproductive sac. During this trip he also visited various museum
throughout Europe and the United Kingdom to examine type specimens.
Starting January 1999, Shaun Winterton spent several months
in the Wiegmann lab (North Carolina) to work on the molecular
systematics of Agapophytus. From there he also attended
with the rest of the therevid PEET group, the PEET III conference
on Monography at the Smithsonian Institute in Washington, DC,
where he presented a poster (right) of part of his work. |

attained his Ph.D. in 2000, and has returned to North Carolina
to assume a post-doctoral position and marry. |
