Abstract

Landmark characters were defined and recorded for 19 species and subspecies of the water mite genus Torrenticola (Acari, Hydrachnellae). This set of taxa has been previously studied by Lundblad (1956), who gives detailed morphological descriptions, standardized drawings of different body parts and metric measurements (distances). The distance data and shape coordinates derived from landmarks are compared in terms of their relative usefulness for discerning alpha taxonomic relationships.
