Nomenclatural Changes For Some Diatoms Found In Iowa, David B. Czarnecki
Nomenclatural Changes For Some Diatoms Found In Iowa, David B. Czarnecki
Journal of the Iowa Academy of Science: JIAS
Nomenclatural revisions for four diatom taxa found in Iowa, two of which are presently maintained in the Loras College Freshwater Diatom Culture Collection (FDCC), are necessary because of systematic interpretations of the Division Bacillariophyta. Achnanthidium hauckianum (Grun.) Czarnecki comb. nov. was originally assigned to the genus Achnanthes Bory. Three taxa were previously assigned to the morphologically diverse genus Navicula Bory. These are Cavinula weinzierlii (Schimanski) Czarnecki comb. nov., Craticula cuspidata var. major [(Meist.) Czarnecki comb. nov. and] Craticula halophila var. subcapitata (0str.) Czarnecki comb. nov.

The Taxonomy And Biology Of Strauzia (Diptera: Tephritidae), W. Bryan Stoltzfus
Journal of the Iowa Academy of Science: JIAS
The North American genus Strauzia is revised. Five new species are included with keys to adults of the 12 known species. Host plant, important larval characteristics, and life cycle information are given for 11 of the species. The evolution of the genus is discussed and 14 host plants are reported. All species bore in the stems of Asteraceae, pupariate in the crown area or in the soil, and are univoltine.
