Multivariate morphometrics of geographic variation of Gerris costae (Heteroptera: Gerridae) in Europe
Revue suisse de zoologie
The waterstrider species Gerris costae (Herrich-Schaeffer) has a large and disjunct distribution in the southern part of the palearctic region. Multivariate morphometric techniques were used to assess the geographic variation in the European part of its range, where three subspecies are currently recognized: G. c. costae (Herrich-Schaeffer), G. c. fieberi Stichel, and G. c. poissoni Wagner and Zimmermann. Twelve variables were selected from a larger set (56 or 57 variables for males anddoi:10.5962/bhl.part.79819 fatcat:rnj5v3ljqbc3rm7ynercalpxly
