Abstract

Scorpions from Utah were collected and studied to determine species present, geographic distribution, seasonal occurrence, sex ratio, and some morphological variations associated with distribution. Nine species were identified--Anuroctonus phaeodactylus, Centruroides sculpturatus, Hadrurus arizonensis, H. spadix, Vejovis becki, V. boreus, V. confusus, V. wupatkiensis, and an undescribed species of Vejovis, subgenus Paruroctonus. Five species--C. sculpturatus, H. arizonensis, V. becki, V. confusus, and V. wupatkiensis--are reported from Utah for the first time. Most specimens were collected from May through October, with greatest numbers taken in May, June, and July. Sex ratios differed with the species. Two species--A. phaeodactylus and V. boreus--showed statistically significant morphological variations in the lengths of the preabdomens.
